I’m hoping it never happens, one of the biggest things I worry about on this island. Cat 3 or worse would be catastrophic for us. 

Yes, even a Cat 1 might be too much, do you remember when we had that high end tropical storm that moved to our west a few years ago? My house was shaking with 80 mph wind gusts.

[TWCCraig]

Probably gusted no more than 30mph here with 0.09" of rain so far. Fell apart pretty fast as it headed east

Thankfully they are conscious, and alert. Taken to hospital as a precaution.

do you know if it was a direct strike or if it hit a tree first or the ground first?

Isaias. Yeah was pretty gusty. Had to drive from south shore to north shore about 4pm and saw plenty of damage. Power at Huntington LIRR was out.

lots of trees down and some very large ones too, I thought my windows were going to blow in that afternoon

The operational ECMWF and GFS are now in good agreement that daily record temperatures will likely be challenged or broken during June 23-24 across the New York City region. June monthly records could be challenged, as well.

Marine layer plus the air is further stabilized from the storm earlier. 

[SACRUS]

 

Ended with around 0.52

[SACRUS]

 

Looks like dew points temps maxed out at 75/76 is the highest i see today.   Slowly dropping now into the upper 60s.

[lee59]

Was in D.C. area this afternoon, numerous trees down and some unfortunately on cars that were on the roadway. Meanwhile back home 88 for a high.

[winterwx21]

Only 0.17" here today. 

[JerseyWx]

Pretty underwhelming here, just some moderate rain at best.  I feel like the strongest severe storms pop up on days when there's less risk.  Today I think we were in enhanced.  It's not like we need the rain anyway.

Breeze kicking up now and can already notice a significant drop in humidity.

who's the guy in the hot tub, Forky?

 

Yes

[Wxoutlooksblog]

Again 2 nights in a row. GFS significant backdoor cold front comes through on Wednesday. CMC, backdoor cold front remains to our north for the entire week. It's the difference between a 3-4 day heatwave starting Sunday and a 5-6 day heatwave starting Sunday. Whatever, upper 90s to lower 100s likely at least Monday & Tuesday. Notably, GFS has a second surge of 90+ degree heat later in the period for at least Saturday 6/28 & Sunday 6/29.

Either we have siting standards or we don't.

Central Park's weather station, located at Belvedere Castle, has been recognized as a Centennial Observing Station by the World Meteorological Organization (WMO). This designation acknowledges the station's continuous, high-quality meteorological measurements for over a century. The Central Park station is one of only eleven such stations in the United States to receive this recognition. 

 

Among the recognition criteria is that Any known observing station relocation or change in the measurement technique have not significantly affected the climatological time-series data.

 

Among the siting standards is that A weather station is supposed to be in an open area, not underneath trees and overgrowth. The best site for the measurements is, therefore, over level ground, freely exposed to sunshine and wind and not shielded by, or close to, trees, buildings and other obstructions.

 

I would argue that the instrument relocation is a qualitative change that materially compromises the long term time series data and defeats the goal of accurate scientific comparison, sort of like the Roger Maris, Mark McGuire asterisk controversy in baseball. Regardless of whether one agrees with this view, it is irrefutable that the siting guidelines are being violated.

Apart from time series comparisons is the issue of comparing NYC weather and climate with other locations and regions and also describing NYC summer weather characteristics to the general public. In the interest of simplicity, summer weather is frequently measured by the number of days which exceed 90 degrees while other factors, such as high minimum temperatures, are basically ignored. Recently, a top meteorologist at a leading weather service provider was giving his summer forecast and it was based on the number of 90 degree days. If I remember correctly he used 16 days as average for NYC while the corresponding figures for other cities were 14 for Boston, 30 for Philly and 40 for DC. While it is certainly true that PHL and DCA have higher summer maxima, this gives the misimpression that overall summer conditions for NYC (usually interpreted as Manhattan) and Boston are largely indistinguishable. Of course you can blame the one dimensional criterion that he used but the thermometer siting is certainly a nontrivial factor. Just as an aside, when comparing NYC to other locations, an overwhelming number of observations are taken in airport or urban environments so maybe concrete is a more useful comparison.

What a glorious morning wow

[SnoSki14]

Temporary relief today before hell unleashes. 

Current forecast for my area is 101-103 Mon-Tue with upper 90s Sunday & Wednesday 

[TJW014]

Pretty pathetic at the beach yesterday evening. One or two distant rumbles of thunder, 35 mph gusts, and a brief 10 minute downpour.

Made for a good 45 minute window to catch a few waves before the sun set. Gotta get some reps before Indonesia.  

Gorgeous morning. Windows will be open all day. Looks to be the best beach day of the coming week.

71 / 56 .  Breezy gorgeous day as the transition bridge to the strong ridge and building heat.  Hot Saturday through the end of the month with peak heat Sun - Wed /  with Mon-Tue hottest days area wide with century mark potential certainly in the hot spots but more area as well.  A nice weekend with storms looking to stay north and clouds clearing to allow sunday off to the races by the afternoon.    Storms Wed pm / night could spoil a 3 100 day streak.  Ridge rebuilds towards the 27th for next weekend 6/28 - 6/29. 

Beyond there overall warm - hot but looks like it could remain wetter with storm chances as ridge in west and along the coast keeps a more humid flow with building heat into the north and east.

Historical:

 

1682 - A major tornado ripped through southwestern Connecticut, passing through Stratford, Milford, and New Haven, and then into Long Island Sound. (Sandra and TI Richard Sanders - 1987)

1921 - Circle, MT, received 11.5 inches of rain in 24 hours, a record for the state. The town of Circle received a total of 16.79 inches of rain that month to establish a rainfall record for any town in Montana for any month of the year. (The Weather Channel)

1928 - A farmer near Greensburg, KS, looked up into the heart of a tornado. He described its walls as rotating clouds lit with constant flashes of lightning and a strong gassy odor with a screaming, hissing sound . (The Weather Channel)

1964 - A squall line producing large hail swept through central Illinois. A second squall line moved through during the early morning hours of the 21st, and a third one moved through shortly after dawn. The series of hailstorms caused nine million dollars damage. Hailstones as large as grapefruit caused heavy damage to trees, utility lines, crops and buildings. The thunderstorms also produced as much as five inches of rain in an eight hour period. (David Ludlum)

1987 - Thunderstorms prevailed east of the Rockies, producing severe weather in the Central High Plains Region. Thunderstorms spawned four tornadoes in Colorado, and produced wind gusts to 70 mph at Goodland, KS. (The National Weather Summary) (Storm Data)

1988 - Thirty-eight cities in the central U.S. reported record high temperatures for the date. Afternoon highs of 97 degrees at Flint, MI, and 104 degrees at Chicago, IL, equalled records for the month of June. Thunderstorms in North Dakota produced baseball size hail near Kief, and wind gusts to 100 mph near McGregor. (Storm Data) (The National Weather Summary)

1989 - An early morning thunderstorm produced wind gusts to 61 mph at Pierre, SD, and the hot thunderstorm winds raised the temperature from 86 degrees at midnight to 96 degrees by 1 AM, and 104 degrees by 2 AM. Butte, MT, and Yellowstone Park, WY, reported snow that afternoon. (The National Weather Summary) (Storm Data)

1989:A meteorological "hot flash" hit Pierre. Descending air from collapsing thunderstorms caused the temperature in Pierre to warm from 86 degrees at midnight to 96 at one a.m. and to 104 at 2 a.m. Pierre's record high for the date of 105 degrees in 1974.

2001: Large hail driven by strong thunderstorm winds raked Denver International and front-range airports. Wind gusting to 54 mph along with hail as large as 2 inches in diameter punched at least 14 thousand holes and cracks in the flat roofs of several buildings at Denver International Airport. Also, 93 planes and hundreds of cars were damaged. About 100 flights had to be canceled stranding 1500 travelers. The Airport was completely shut down for about 20 minutes. The storm also damaged ground avoidance radar used to track planes on the ground to prevent collisions. Damage was estimated at 10 million dollars not counting the cost to the 93 airliners. The storm moved south and struck Watkins Colorado with hail as large as 2 1/2 inches in diameter and winds gusting to 60 mph.
