IPT missed the record high by a degree. Looks like CDW was the warmest in our area at 95°. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KCDW

EWR gusted to 71 mph. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KEWR

Very heavy downpour, frequent lightning, and 20-30 mph gusts here in SW Suffolk.

The radar velocity looks like there may have been some 50+ gusts around Miller Place and Rocky Point.

Southhold gusted to 52 mph. http://www.nysmesonet.org/weather/meteogram#network=nysm&stid=sout

91° now in Wantagh with a 96° HX. http://www.nysmesonet.org/mesonow#network=nysm&stid=want

Harrisburg made it to 98° with the warm downslope flow. Late afternoon high temperatures for our area as WAA keeps going into this evening. 850s peak at +18C to +20 C in a few hours. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KCXY

Yeah, it felt great. Looks like the warm front is further north today than expected. The NAM has us warming into the 90s as the flow becomes more WSW this afternoon.

Unfortunately, these rapid intensifications prior to landfall have become more common in recent years. https://www.wunderground.com/cat6/Highly-Unusual-Upward-Trends-Rapidly-Intensifying-Atlantic-Hurricanes-Blamed-Global-Warming It’s very sobering to see that two of the most rapidly intensifying hurricanes before landfall (Michael in 2018 and Harvey in 2017) since 1950 have occurred in the past two hurricane seasons, and that a significant increase in such rapidly intensifying hurricanes is predicted by some of our top computer models. Since 1950, here are the greatest 24-hour intensification rates prior to a U.S. landfall: Since 1950, here are the greatest 24-hour intensification rates prior to a U.S. landfall: Humberto 2007 (65 mph increase, Cat 1 landfall) King 1950 (60 mph increase, Cat 4 landfall) Eloise 1975 (60 mph increase, Cat 3 landfall) Danny 1997 (50 mph increase, Cat 1 landfall) Michael 2018 (45 mph increase, Cat 5 landfall) Harvey 2017 (40 mph increase, Cat 4 landfall) Cindy 2005 (40 mph increase, Cat 1 landfall)

Today was our lowest humidity on Long Island since the end of June. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=157&network=NY_ASOS&station=ISP&year=2020&var=min_rh&dir=above&thres=95&dpi=100&_fmt=png

Most impressive temperature gradient of the summer tomorrow ahead of the severe threat. This will be one of the few times this year that the strongest heat won’t be found over New England. Maybe the warmest spots around the region can make another run on 95°.

Finally got a NW flow day with dew points in the low 50s. We may see the next one Sunday into Monday. Kennedy Intl PTCLDY 69 53 56 NW10

Great view from the Queens College Mesonet. http://www.nysmesonet.org/mesonow#network=nysm&stid=quee

Yeah, it fits the pattern really well. https://www.climate.gov/news-features/blogs/beyond-data/climate-change-rule-thumb-cold-things-warming-faster-warm-things Climate change rule of thumb: cold "things" warming faster than warm things Colder places are warming faster than warmer places Colder seasons are warming faster than warmer seasons Colder times of day are warming more than warmer times of day

Yeah, looks like you were one of the cooler spots along the general I- 84 corridor.

It took until the end of the month for the Pacific to finally become favorable. The models were showing fantasy day 6-10 snows for much of December before Boxing Day delivered.

It could be the 5th La Niña-like winter in a row for us. The La Niña background state has been very persistent since 16-17. The SE Ridge was a big player for us last 4 winters. La Niña winter snowfall is usually determined by whether NYC gets 3” of snow in December or not. So we should get an early idea of seasonal snowfall potential. Every La Niña-like snowfall season since 95-96 with under 3” in December turned out below normal like the last 2 winters. All the 3”+ Decembers featured above normal seasonal snowfall. Even the mild La Niña winters like 17-18, 16-17 and 05-06 did well in the snowfall department.
