July 2025 Discussion-OBS - seasonable summer variability

[wdrag]

Pretty good chance will issue a thread for Fri-Sun at 8P this evening.

Includes SVR FF potential Fri afternoon (in my opinion only-despite weak 5-7H lapse rates T/TD spreads of 30F at max heating 2PM Fri will favor downdrafts-downbursts---especially near NYC) as well as 'possible' first 100F NYC since 2012; and SVR FF Sunday with  spot 5" 72 hr total by 06z/Monday.  

I know the group think is that CP is viewed as a cooling center relative to surroundings.  However, EC continues pushing 100 for NYC.  We'll see if its too aggressive.

Well done Walt! Referring to Central Park as a, thought of, cooling center was civil,  diplomatic  and for many true. Stay well and cool, as always ….

It’s really cool that they just updated the Newark area weather records back to 1843. They used to average only 6 days reaching 90° a year from 1843 to 1872. The winter weather records are pretty fun to look at also.

How do the records in the Newark area go that far back? 

I thought Central Park had the longest period of records around here and that goes back to 1869.

If we get a bunch of offshore wind days behind cool fronts, the SSTs will cool down from upwelling. The warm waters here are shallow. But no doubt if we go through Aug with these warm waters we’re asking for trouble-either from a tropical system or stalled out front and MCS deluge like we saw last summer and happens most frequently in August around here. 

What the water temps are within 25 miles of the coast has little impact on any tropical activity up here. Because we have some of the longest and shallowest continental shelf in the world. Super shallow water has little to no OHC. That’s why it’s left off OHC maps.

What we need to focus on is the water temps from 50 to 300 miles off the coast. And those waters are less effected by localized upwelling events. Those waters are currently near record warm.

78 / 64 sunny.   First warm - hot day with upper 80s - low 90s in the hot spots.  Tomorrow pending on afternoon clouds / showers-storms, mid - upper 90s in the hot spots - see if anyone can get 100.  Saturday cooler with onshore flow but inland hot spots still to low 90s.  Sunday storms / clouds likely keep the heat at bay to the south and west as the ridge retreats then builds back north with more heat mon - Wed.  Ride backs west by Wed and sets up cooler period between 7/31 - 8/5-6.   Looks to get warm - hot /humid towards the 6th with onshore flow coming around more southerly flow.  Heat expanding east - Atlantic ridge coming west - probabyl spells a much warmer / wetter second half.

Certainly would have been a very pleasant July climate, which is a good thing in the pre-AC days.

I always liked that Toronto, Canada has continuous records back to 1840. Seems to paint a similar picture, obviously Toronto being colder in general.

July 1859 was probably the most comfortable one from that era with only 2 days reaching 90° and 10 days with lows in the 50s.

1886 - Rain fell at Lawrence, KS, for the first time in four weeks. Rain fell over much of the state of Kansas that day relieving a severe drought which began in May. The very dry weather ruined crops in Kansas. (David Ludlum)

 

1931: Searing heat prevailed in the San Joaquin Valley in California. Many locations saw highs of 110 °F or better from the 21st through the 26th. Highs on this date reached 114 °F at Bakersfield, 113 °F at Hanford, 112 °F at Madera and 111 °F Wasco. (Ref. Wilson Wx. History)

1934: A terrible heat wave settled over much of the Midwest. South Bend, IN and Chicago, IL set their all-time high temperature records of 109 °F and 105 °F respectively. Lansing, MI equaled their all-time high temperature of 102°. (Ref. Wilson Wx. History)

1936 - A record all time Kansas state high temperature set just 6 days earlier was tied in the town of Alton, located in Osborne County. (US National Weather Service Wichita)


1936: The state maximum temperature record for Kansas was equaled today at Alton, Kansas which was 121 °F. The state maximum temperature record for Nebraska was also equaled today at Minden, Nebraska which was 118 °F. (Ref. Lowest and Highest Temperatures for the 50 States)

1942 - The temperature at Las Vegas, NV, hit 117 degrees to set an all-time record for that location. The record was tied on July 19, 2005.

1947 - One of the most powerful strokes of lightning ever measured yielded 345,000 amperes of electricity in Pittsburgh, PA. (The Weather Channel)

1952 - The temperature at Louisville, GA, soared to 112 degrees to establish a state record. (The Weather Channel)

1979: The name Claudette has been used for six tropical cyclones in the Atlantic Ocean. This Claudette, a weak tropical storm, deluged southeastern Texas with torrential rains. The Houston suburb of Alvin received 43 inches, a 24-hour record for the U.S. (David Ludlum)

1984: Only four days of 90 °F heat for July in Washington, DC, the least since 1962 then only two. (Ref. Washington Weather Records - KDCA)

1980 - Claudette, a weak tropical storm, deluged southeastern Texas with torrential rains. The Houston suburb of Alvin received 43 inches, a 24 hour record for the U.S. (David Ludlum)

1987 - Twenty-one cities in the eastern U.S. reported record high temperatures for the date. The high of 91 degrees at Beckley, WV, was their hottest reading in 25 years of records, and marked their third straight day of record 90 degree heat. Bakersfield, CA, dipped to 60 degrees, marking their eighth straight morning of record cool weather. (The National Weather Summary)

1988 - Afternoon and evening thunderstorms produced large hail and damaging winds in Oklahoma, and over Nebraska and Wisconsin. Thunderstorms produced wind gusts to 75 mph at Brainerd, NE. (The National Weather Summary) (Storm Data)

1989 - Afternoon thunderstorms produced some flash flooding in New Mexico. Albuquerque, NM, was deluged with an inch and a half of rain in forty minutes. Evening thunderstorms soaked Whie Pine, PA, with two inches of rain in one hour. (The National Weather Summary) (Storm Data)

 

1993: A severe thunderstorm struck southern Hyde County, SD including the city of Highmore, with winds in excess of 60 mph and heavy rains of 2 to 4 inches. Near Stephan, an estimated 4 inches of rain fell in 20 minutes causing flood damage around a bridge. 3 to 9 inches of rain caused widespread flash flooding and flood damage to Day, Roberts, and southeastern Marshall Counties. A state of emergency was declared in Sisseton. The heavy rains overwhelmed a small creek that flows through Sisseton, swelling it to three blocks wide and up to 5 feet deep. Flood damage occurred to 70% of all buildings in Sisseton, including 100 homes. Roads and bridge damage was also extensive in Roberts, Day, and Marshall Counties with about 50 roads and bridges in Day County damaged by the flooding.HR> The line of thunderstorms exploded over southeast Nebraska then advanced into Iowa at nearly 60 mph. An amazing two inches of rain fell in 30 minutes at Council Bluffs. Winds of 70 mph or greater were widespread across western Iowa. 75 mph winds also struck southeast of Treynor. (Ref. Wilson Wx. History)

1995: Severe thunderstorms slashed through west and south Oklahoma City, OK just after midnight, leaving 175,000 people without power. Cleanup from downed trees took several weeks. Will Rogers Airport reported a wind gust of 97 mph. (Ref. Wilson Wx. History)

1996: A wet microburst centered over eastern Presidio, TX caused extensive damage over portions of the city. The winds destroyed 7 mobile homes and damaged up to 50 homes, businesses, and a school. Wind estimates put the speeds at up to 100 mph in the worst damage. Power was out for about 5.5 hours in parts of the city. (Ref. Wilson Wx. History)

1998: Lightning struck five rescue personnel as they rendered aid to occupants of an overturned truck along Interstate 15 near Sloan, NV. As the storm moved north, outflow winds estimated at 65 - 70 mph were observed by a NWS meteorologist near Lake Mead Drive and Interstate 15. Before dissipating, the thunderstorm produced another lightning strike which set fire to an apartment building in Henderson. (Ref. Wilson Wx. History)

2007: Miles City, Montana: Miles City hits 110°F. (Ref. WxDoctor)

 

2008: A tornado fluctuated between the category EF1 and the more destructive EF2 strikes Northwood and Pittsfield, as well as nine other towns in New Hampshire. It first touches down in Deerfield, then travels through Northwood, Epsom, Pittsfield, Barnstead, and Alton. From there, it rages through New Durham, Wolfeboro, Freedom, Ossipee, and Effingham. The storm destroys several homes, damaged dozens of others and kills at least one person.

2010: The 105 °F recorded at the Richmond International Airport today ties the highest maximum temperature ever recorded in July in Richmond. The high of 105 °F and low of 79 °F today yields a daily average temp of 92.0 °F which breaks the all-time daily mean temp of 91.5. Thus making today the hottest day ever recorded in the past 113 years for Richmond. (Ref. Richmond Weather Records - KRIC) This highest temperature ever recorded for July of 105 °F has occurred on two other dates. (Ref. Richmond Weather Records - KRIC) DCA soared to a record 102 °F on the 7th and 101 °F on the 24th.
BWI recorded record high temperatures on 4 days: 6th (105 °F), 7th (101 °F), 24th (101 °F) and 25th (100 °F) BWI had on 5 days above 100 °F making the most on record. At or above 90 °F on 44 days in 2010 at DCA, most number of days through July on record.
Ref. July PRESTO Page 1

2012: Tuesday morning’s July 24, 2012 a severe thunderstorm with widespread 60-70mph winds in the Chicago area knocked out power to 300,000 at the peak. It was a bad storm with 55-70mph winds in Oak Park, IL again! From Tom Skilling’s blog - - - The line broke up over Blacksburg and Richmond and then reformed along the Eastern shore of Virginia !

Trough into the northeast Jul 31 - Aug 5/6  - onshore in that period and then southerly warmer/humid flow into the 2nd week of August.  Euro matches the GFS overall for the 7-10 period.

I think New Brunswick, NJ go back into 1890 as well.

So they were just sitting on this data for all these years and decided to all of a sudden release it?

I didn't think anyone was even keeping daily weather records in Newark from the early 1840s. 

How does the weather record of Newark beat NYC's by almost 30 years?

all Central Park records need to be put in a museum and do not update them anymore.

With all the shit government is doing these days, why can't they overrule the Conservancy bring a bunch of chain saws and chop down the trees? You know if they cared they could.

But they have continuous records going back to 1843 or just for a smaller time set (like from the 1840s to the 1860s)?

Historical:

 

1886 - Rain fell at Lawrence, KS, for the first time in four weeks. Rain fell over much of the state of Kansas that day relieving a severe drought which began in May. The very dry weather ruined crops in Kansas. (David Ludlum)

 

1931: Searing heat prevailed in the San Joaquin Valley in California. Many locations saw highs of 110 °F or better from the 21st through the 26th. Highs on this date reached 114 °F at Bakersfield, 113 °F at Hanford, 112 °F at Madera and 111 °F Wasco. (Ref. Wilson Wx. History)

1934: A terrible heat wave settled over much of the Midwest. South Bend, IN and Chicago, IL set their all-time high temperature records of 109 °F and 105 °F respectively. Lansing, MI equaled their all-time high temperature of 102°. (Ref. Wilson Wx. History)

1936 - A record all time Kansas state high temperature set just 6 days earlier was tied in the town of Alton, located in Osborne County. (US National Weather Service Wichita)


1936: The state maximum temperature record for Kansas was equaled today at Alton, Kansas which was 121 °F. The state maximum temperature record for Nebraska was also equaled today at Minden, Nebraska which was 118 °F. (Ref. Lowest and Highest Temperatures for the 50 States)

1942 - The temperature at Las Vegas, NV, hit 117 degrees to set an all-time record for that location. The record was tied on July 19, 2005.

1947 - One of the most powerful strokes of lightning ever measured yielded 345,000 amperes of electricity in Pittsburgh, PA. (The Weather Channel)

1952 - The temperature at Louisville, GA, soared to 112 degrees to establish a state record. (The Weather Channel)

1979: The name Claudette has been used for six tropical cyclones in the Atlantic Ocean. This Claudette, a weak tropical storm, deluged southeastern Texas with torrential rains. The Houston suburb of Alvin received 43 inches, a 24-hour record for the U.S. (David Ludlum)

1984: Only four days of 90 °F heat for July in Washington, DC, the least since 1962 then only two. (Ref. Washington Weather Records - KDCA)

1980 - Claudette, a weak tropical storm, deluged southeastern Texas with torrential rains. The Houston suburb of Alvin received 43 inches, a 24 hour record for the U.S. (David Ludlum)

1987 - Twenty-one cities in the eastern U.S. reported record high temperatures for the date. The high of 91 degrees at Beckley, WV, was their hottest reading in 25 years of records, and marked their third straight day of record 90 degree heat. Bakersfield, CA, dipped to 60 degrees, marking their eighth straight morning of record cool weather. (The National Weather Summary)

1988 - Afternoon and evening thunderstorms produced large hail and damaging winds in Oklahoma, and over Nebraska and Wisconsin. Thunderstorms produced wind gusts to 75 mph at Brainerd, NE. (The National Weather Summary) (Storm Data)

1989 - Afternoon thunderstorms produced some flash flooding in New Mexico. Albuquerque, NM, was deluged with an inch and a half of rain in forty minutes. Evening thunderstorms soaked Whie Pine, PA, with two inches of rain in one hour. (The National Weather Summary) (Storm Data)

 

1993: A severe thunderstorm struck southern Hyde County, SD including the city of Highmore, with winds in excess of 60 mph and heavy rains of 2 to 4 inches. Near Stephan, an estimated 4 inches of rain fell in 20 minutes causing flood damage around a bridge. 3 to 9 inches of rain caused widespread flash flooding and flood damage to Day, Roberts, and southeastern Marshall Counties. A state of emergency was declared in Sisseton. The heavy rains overwhelmed a small creek that flows through Sisseton, swelling it to three blocks wide and up to 5 feet deep. Flood damage occurred to 70% of all buildings in Sisseton, including 100 homes. Roads and bridge damage was also extensive in Roberts, Day, and Marshall Counties with about 50 roads and bridges in Day County damaged by the flooding.HR> The line of thunderstorms exploded over southeast Nebraska then advanced into Iowa at nearly 60 mph. An amazing two inches of rain fell in 30 minutes at Council Bluffs. Winds of 70 mph or greater were widespread across western Iowa. 75 mph winds also struck southeast of Treynor. (Ref. Wilson Wx. History)

1995: Severe thunderstorms slashed through west and south Oklahoma City, OK just after midnight, leaving 175,000 people without power. Cleanup from downed trees took several weeks. Will Rogers Airport reported a wind gust of 97 mph. (Ref. Wilson Wx. History)

1996: A wet microburst centered over eastern Presidio, TX caused extensive damage over portions of the city. The winds destroyed 7 mobile homes and damaged up to 50 homes, businesses, and a school. Wind estimates put the speeds at up to 100 mph in the worst damage. Power was out for about 5.5 hours in parts of the city. (Ref. Wilson Wx. History)

1998: Lightning struck five rescue personnel as they rendered aid to occupants of an overturned truck along Interstate 15 near Sloan, NV. As the storm moved north, outflow winds estimated at 65 - 70 mph were observed by a NWS meteorologist near Lake Mead Drive and Interstate 15. Before dissipating, the thunderstorm produced another lightning strike which set fire to an apartment building in Henderson. (Ref. Wilson Wx. History)

2007: Miles City, Montana: Miles City hits 110°F. (Ref. WxDoctor)

 

2008: A tornado fluctuated between the category EF1 and the more destructive EF2 strikes Northwood and Pittsfield, as well as nine other towns in New Hampshire. It first touches down in Deerfield, then travels through Northwood, Epsom, Pittsfield, Barnstead, and Alton. From there, it rages through New Durham, Wolfeboro, Freedom, Ossipee, and Effingham. The storm destroys several homes, damaged dozens of others and kills at least one person.

2010: The 105 °F recorded at the Richmond International Airport today ties the highest maximum temperature ever recorded in July in Richmond. The high of 105 °F and low of 79 °F today yields a daily average temp of 92.0 °F which breaks the all-time daily mean temp of 91.5. Thus making today the hottest day ever recorded in the past 113 years for Richmond. (Ref. Richmond Weather Records - KRIC) This highest temperature ever recorded for July of 105 °F has occurred on two other dates. (Ref. Richmond Weather Records - KRIC) DCA soared to a record 102 °F on the 7th and 101 °F on the 24th.
BWI recorded record high temperatures on 4 days: 6th (105 °F), 7th (101 °F), 24th (101 °F) and 25th (100 °F) BWI had on 5 days above 100 °F making the most on record. At or above 90 °F on 44 days in 2010 at DCA, most number of days through July on record.
Ref. July PRESTO Page 1

2012: Tuesday morning’s July 24, 2012 a severe thunderstorm with widespread 60-70mph winds in the Chicago area knocked out power to 300,000 at the peak. It was a bad storm with 55-70mph winds in Oak Park, IL again! From Tom Skilling’s blog - - - The line broke up over Blacksburg and Richmond and then reformed along the Eastern shore of Virginia !

Most of the area was extremely rural back then.

Definitely zero cars.

 

It really makes the historic summer of 1896 in which 1,500 people died stand out.

Certainly would have been a very pleasant July climate, which is a good thing in the pre-AC days.

I always liked that Toronto, Canada has continuous records back to 1840. Seems to paint a similar picture, obviously Toronto being colder in general.

Thats not a continuous record from 1843 to today though is it?

Do they have snowfall records too?

the winter of 1859 was brutally cold even for 1800s winters

What the water temps are within 25 miles of the coast has little impact on any tropical activity up here. Because we have some of the longest and shallowest continental shelf in the world. Super shallow water has little to no OHC. That’s why it’s left off OHC maps.

What we need to focus on is the water temps from 50 to 300 miles off the coast. And those waters are less effected by localized upwelling events. Those waters are currently near record warm. 
 

Here’s the Delaware bay buoy 
 

Yes this is why you actually need westerly flow to get some of our hottest waters.

It's a complex process but from what I read you first need westerly flow with a long duration extreme heat wave followed by southerly onshore flow.  The westerly flow heats up the far offshore waters (since no upwelling happens there) and then the later onshore flow brings that water closer to shore.  That's why 2011 held our previous record for warmest waters.  We first had the record extreme triple digit heatwave with westerly flow, followed later by onshore flow.

The models sped up the frontal passage. While we still get a sea breeze, there is now a late day wind shift to the WNW. So areas from Huntington to maybe Commack could go 95°+. Even JFK could go mid-90s with that wind shift. The wild card will be convection. If it breaks up or heads to our south, then even the South Shore could have a late day high after the mid-day sea breeze. Another scenario would be a warm up on the outflow boundary if the convection comes right through the area. Where the sea breeze reverses on the NW gust front with a late day temperature jump. Saw this a bunch of times back in Long Beach.

Nice WNW wind is my favorite summer wind direction !!!

Most of the hot weather from here on out appears to me to be borderline heat as in upper 80s to lower 90s not the kind of furnace heat we saw the last week of June. While I can't rule out one longer heatwave sometime in August featuring again, mostly lower 90s, I think the odds are slightly against it. I am concerned about a pattern which to me looks ripe for tropical development off of the southeast coast of the U.S. or in the southwest Atlantic. And we'll have eventually what I'd call a dirty ridge over most of the east up into eastern Canada during August with some upper lows embedded at times that could pull a storm northward up the eastern seaboard.

I guess on Friday NYC could get up to about 92 or 93.

WX/PT

Last time NYC had 100 degree in August (notably it was 103!) was on August 9, 2001, that's 24 years ago lol.

Last time JFK hit 100 degrees in August (they did so in both July and August in that year) was August 20, 1983.  1983 is on my list of all time summers, with a very hot June, July, August AND September (can't argue with 7 90 degree days in September including a peak of 99 on 9/11/1983 at NYC.)

Newark also had what is considered the greatest minor league baseball team of all time (they were so good, they were considered a major league team.)
