(Ref. Wilson Wx. History) 1816: The mean temperature for June 1816 in Philadelphia, PA was a record breaking 64°F (p.33 Washington Weather Book 2002 by Ambrose, Henry, Weiss) 1841: A tornado hit Danvers, Salem, and Marblehead, MA. During this severe weather event, small fish fell on a street in Boston. (Ref. Wilson Wx. History) 1886 - The second destructive hurricane in nine days hit the Apalachicola-Tallahassee area. (David Ludlum) 1900: The combination of high winds and the presence of wooded fuel-filled cargo helped to spread fire on the Hoboken Docks in New Jersey. The fire began when cotton bales caught fire and spread to nearby volatile liquids. The fire killed at least 300 people and was seen in New York City. 1901 Maximum temperature greater than 85° in Washington, DC from June 21st until July 7th, and greater than 90°F from 25th to 4th and 98° on 30th. (Ref. Washington Weather Records - KDCA) 1908: A huge fireball streaked across the sky during the early morning hours over Siberia. A huge explosion occurred in the air near the remote Stony Tunguska River. The explosion flattened trees for 40 miles around and killed wildlife, but no crater or meteorite fragments were ever found. (Ref. Wilson Wx. History) 1930: The Great Drought of 1930-1931 the year of 1930 was the driest year since the drought of 1869 to 1870. The drought caused $40 million dollars (1930 dollars) in losses to farmers in Maryland alone. Forest fires by the dry spell caused $580,000 in losses in Maryland. The precipitation deficit began in December 1929 and was fully classified as a drought by May of 1930. An extreme dry period set in from the end of June 1930 and continued through February 1931. During the 15-month period from December 1929 through February 1931, most places saw 60 percent or less of their normal rainfall. The average precipitation across Maryland and Delaware was 29.58 inches, which was 21.51 inches below normal. Baltimore recorded 27.31 inches for the 15-month period that was 23.03 inches below normal or 54% or normal. Washington, DC recorded 26.78 inches, which was 20.40 inches below normal or 57% below normal. The drought of 1998 to 1999 did not come near this severity, but it was the second severest drought of this century. The Palmer index, which is used to signal drought severity, classifies values of -3 to -4 as "severe drought" and values at -4 or less as "extreme drought". The Palmer Index for the region reached its lowest values during the end of the extreme dry period. In Maryland, west of the bay, Northern Virginia and the eastern panhandle of West Virginia, the Palmer Index was between -6.5 and -7.5 for January and February. Areas experienced up to 17 months of extreme drought conditions. The drought moderated some after February 1931 with periodic rains and showers through the summer months that helped the crops. However, these rains were not enough to restore the water table and water flow levels. Officially the drought did not end until about May 1932. 1942 - The temperature at Portland, OR, hit 102 degrees, an all-time record for that location. (The Weather Channel) 1949: Only 0.02 inches of rain fell at Central Park in New York City for its driest month on record. (Ref. Wilson Wx. History) 1968: A cloudy June came to an end in Sault Ste. Marie, MI. Not one clear day was observed during the month. (Ref. Wilson Wx. History) 1972: The entire state of Pennsylvania was declared a disaster area as a result of the catastrophic flooding caused by Hurricane Agnes, which claimed 48 lives, and caused 2.1 billion dollars damage. (The Weather Channel) 1972 - The entire state of Pennsylvania was declared a disaster area as a result of the catastrophic flooding caused by Hurricane Agnes, which claimed 48 lives, and caused 2.1 billion dollars damage. (The Weather Channel) 1978: Havre, MT measured a wind gust to 138 mph from a severe thunderstorm. (Ref. Wilson Wx. History) 1986: Thunderstorms produced large hail and high winds in southwest South Dakota. During the afternoon hours hail up to the size of baseballs pounded Ellsworth Air Force base near Rapid City. 20 people were hurt at the Air Force Base as the hail broke over one thousand windows. Hail was 3 to 6 inches deep on the roads in Spearfish Canyon in the Black Hills and snowplows needed to be called out to clear the roads. 1986: Today marked the end of the driest six months on record for the Athens, GA area since records began in 1845. The six month precipitation total at Athens was 11.23 inches compared to the normal of 27.33 inches. This also marked the end of the driest six months on record for Lynchburg, VA, with only 9.43 inches measured. Where as San Antonio, TX had their wettest June on record with 11.95 inches of rain besting the previous record of 10.44 inches set back in 1973. (Ref. Wilson Wx. History) 1987 - Hot weather prevailed in the Pacific Northwest, with readings above 100 degrees reported as far north as southern British Columbia. Yakima, WA, reported a record high of 100 degrees, while temperatures near the Washington coast hovered near 60 degrees all day. Thunderstorms prevailed from southwest Texas to New England. Thunderstorm winds gusting to 100 mph at Gettysburg, PA, killed one person. High winds and large hail caused more than five million dollars damage to property and crops in Lancaster County, PA. (The National Weather Summary) (Storm Data) 1988 - Thunderstorms in eastern Kansas drenched Worden with 12.21 inches of rain, and a wall of water two to four feet deep swept through Lone Star, KS, flooding every home in the town. Up to ten inches of rain was reported southeast of Callaway, NE. Thunderstorm winds gusted to 75 mph at Winfield, KS. Seventeen cities in the north central and northeastern U.S. reported record low temperatures for the date, including Duluth, MN, with a reading of 36 degrees. (The National Weather Summary) (Storm Data) 1989 - Winnfield, LA, reported 22.52 inches of rain in three days, and more than thirty inches for the month, a record for June. Shreveport LA received a record 17.11 inches in June, with a total for the first six months of the year of 45.55 inches. Thunderstorms also helped produce record rainfall totals for the month of June of 13.12 inches at Birmingham AL, 14.66 inches at Oklahoma City, OK, 17.41 inches at Tallahassee FL, 9.97 inches at Lynchburg, VA, and more than 10.25 inches at Pittsburgh, PA. Pittsburgh had also experienced a record wet month of May. (The National Weather Summary) 1991: Five inch diameter hailstones bombarded a spot near the town of Hathaway, MT. (Ref. Wilson Wx. History) 1992: 399 tornadoes occurred across the U.S. during June. This set a new record for the greatest number of tornadoes in a single month up to that time (this record was broken in May 2003). (Ref. Wilson Wx. History) 1993: Across parts of South Dakota, June of 1993 was a cool and wet month. In Iowa, temperatures averaged nearly three degrees below normal while precipitation averaged 8.09 inches, which is 3.67 inches above normal. Le Mars was one of only two stations which recorded below normal rainfall for June of 1993, but still received 3.09 inches. Not too far away though, Estherville recorded its wettest month on record with an astounding 13.49 inches. 1993: Mississippi River levels rose dramatically during the last half of the month. On the Upper Mississippi River basin near the Quad Cities, river levels rose above major flood levels which occurred in 1965 and 1973. (Ref. Wilson Wx. History) 1994: El Paso, TX soared to 114° to break their all-time record high temperature, again. A record high of 113° was just set on the 27th and 28th of this month. (Extreme Weather p. 277, by Christopher C. Burt - The 1981 record) (Ref. Wilson Wx. History) 1999: Mount Baker, Washington closed out a record snowfall season both for the United States and the verifiable world record as the seasonal total from July 1, 1998, to June 30, 1999, finished with 1,140 inches. 2001: A severe thunderstorm at 1 AM produced baseball size hail and 80 mph winds at Ashland, MT.

One of the women was critically injured when “scalped” by flying debris. (Ref. Weather Guide Calendar with Phenomenal Weather Events 2011 Accord Pub. 2010, USA) 2010: The hottest June on Record! The Richmond International Airport reported the mean temperature for June was 81.1 °F which was a new 113 year record. This breaks the old record of 79.2 °F set in 1943 and was a +8.7 °F departure from average. June had 8 new daily temperature records and all were for heat. Both June 27th and 28th had a maximum temperature 102 °F. Richmond has never had back to back 102 °F days before in June. Only three June days have been hotter: (June 30, 1937 103 °F) (June 19, 1944 103 °F) (June 26, 1952 104 °F ) June 2010 also had 19 days of 90 °F or higher temperatures the record was 20 in 1943. June had only 0.82 inches rainfall making it the second driest in 113 years only 1980 was drier with only 0.38 inches and with the heat made severe drought conditions. (Ref.

Amazing You-Tube Video of a Very Close Lightning Strike) (Ref. NWS Tells the Complete Story in a 5 Min. Movie) 2015: The heat was a big story for us throughout the month of June. It may come as no surprise then that this was one of the warmest Junes on record in Richmond. Our average temperature was 77.92° for the month. That was high enough to place June 2015 as the 8th warmest June in Richmond since record-keeping began in 1880. Richmond International Airport normal average temperature is 74.3°F. Richmond's (Ref. NWS Wakefield) 2021: An intense late-June heat wave peaked across the Northeast on June 30, 2021, as a powerful upper-level ridge sent temperatures soaring into the upper 90s and lower 100s. Newark Liberty International Airport (EWR) reached 103°F, setting its hottest June temperature on record, while LaGuardia Airport (LGA) climbed to 101°F, tying its hottest June reading ever. Central Park reached 98°F, and Boston hit 100°F, marking its hottest June temperature on record. The remarkable heat capped one of the warmest Junes ever observed across much of the Northeast and produced numerous daily and monthly temperature records from New Jersey through southern New England.

78 / 66 day 2 for a few and for many others day 1 of a 5-6 or 7 day heatwave peaking Wed - Sat. Isolated / scattered storms Fri - Sat and look for MCS which looks north into New England if develops. Sunday looks a bit unsettled but enough sun extends the heatwave for the areas. Ridge > 594 DM and 850s peaking >22c Thu-Sat argues upper 90s / low 100s, maybe mid low - mid 90s in central park. Next week near to slightly above normal between 7/7 - 7/14 with ridge pulling back west and weak trough into the northeast. WC / Rockies ridge pumps up and pushes pieces of heat east towards mid month. The usual transition from these strong ridge / heat spikes is followed by near / below normal for 3 - 7 days before next push of heat.

Hey all. First time poster, long time reader. I was up in Slate Run on Pine Creek during the worst of the July 2011 heatwave. All the trout were huddled where the tiny seeps and feeders trickled into the main stem of Pine creek. They were so distressed you could pick them up with your hands. Walleye just floated up to the surface and you could grab them by hand as well. I don't know what the water temperature was, but there was no relief from being in the water.

Looks like we are going to finish June with a negative temperature departure for the month. A warm period at the beginning and end of the month couldn't overcome an incredibly pleasant middle part. It would take something like +42 departure today to bring us back to normal. It might feel like it with the humidity today, but that is a different story.

all kidding aside July 4th PM has some potential for the atmosphere to put on its own show in the region

81/78/89 at 8:30am... No thanks

Early July 1966-104,107,104 followed by a 100 on July 10th,and 100 on July 26th. and most other days that Summer were in the 90's

Even the GFS has a quite a bit of elevated CAPE with at least western sections on the instability gradient. It will be an interesting evening/overnight, especially if the NAM sort of verifies with the advection of rather impressive MUCAPE. The HRRR I think has been solid with the idea of convection moving into the region this evening but I think this may end up being a bit more impressive than modeled. These are tough environments, even more mesos to handle

I can remember back in 1988 summer when it was hot. I took a thermometer in the creek at my place where we have a swimming hole in the middle of the creek. The hole is about 5 foot deep in between 2 big rocks. In between the rocks the current flows, thats where I held a wire that was attached to My thermometer about half a foot under the water. The temperature was 88. The water felt like bath water. You cooled off but it wasn't exactly what I call refreshing. If we get several days of hot temperatures this week I'll have to see what the temperature of the creek is this time.

DCA: 98, 102, 103, 101 BWI: 97, 102, 103, 100 IAD: 96, 99, 101, 98 SBY: 96, 99, 101, 98 RIC: 97, 100, 102, 99 Total Rain: 0.05

I planted Texas grass seed in my full sun spots for a reason…

Also where there’s any compressional heating zone. That area just ahead of the seabreeze can really roast. Sometimes that’s around the Southern State Parkway/Five Towns to Roosevelt Field.

86 yesterday on the south shore For Long Island, the Euro has a prominent sea breeze on Thursday so Euro only has 90s for the island that day. West wind comes back on Friday (Euro) so that would be our best chance at 100+. GFS has more of a westerly wind both days but there will probably be a sea breeze both days. Where it sets up during the day will dictate the max temps. Longer it holds off, the hotter it'll get

Woke up to 24C/77F maybe locally more like 25C as of 7:30, I see CU in the distance with minor haze - that's my kind of morning! Low of 21C only. They adjusted for 44 humidex.

Not exactly— there’s definitely indication that the line bends southeast. Down to Boston in the mix for severe along the coast.

Still stuck in the clouds and fog, although point has 94 for the high today. It's the only 90+ temp in the forecast this week after yesterday's high temp busted by 22 degrees... .75" of rain the past 24 hours from a couple rounds.

Wildfire smoke is back. Noticed some yesterday and today it’s very noticeable

NOT looking forward to the next several days

Today should be our last sub 90 degree high until Monday. Mid to upper 80's today rising into the low to mid 90's tomorrow and then upper 90's in higher spots to near 100 in our valley locations both Thursday and Friday. Shower chances increase later July 4th with the days trending slightly cooler with highs by Monday in the upper 80's.

Glad the temps haven’t reached 100 yet, highs around 95 and only a couple heat advisories this summer which is pretty surprising.

MDT daily record highs for July 1 thru July 4 -- 100, 104, 107, and 104. That is one tough set of records to breach. Tomorrow is obviously the most gettable but that's also the one day where my current forecast is under 100. We shall see but quite the historic heat wave on tap regardless.

woke up to 80, lol

Historically will this 3-4 day stretch sit near the top? I think last time 3 days of 100 or greater was July 93?

Just a reminder that this will stay open for entries and edits until about 11PM tonight. In the spirit of transparency, my entries above are final.
