Winds increasing quickly now on the South Shore with Gilgo Beach gusting to 42 mph. https://www.wunderground.com/dashboard/pws/KNYBABYL18/table/2020-02-7/2020-02-7/daily

Warm front just came through here on the South Shore. 51 degrees and south winds gusting to 24 mph in Wantagh.

We continue to see the 240hr SE ridge correct stronger than the 360hr forecast.

The warm sector where the high winds will develop is already into Philly. They jumped 8 degrees from 48 to 56 in just 30 minutes. Winds are now gusting close to 40 mph with pressure at 982 mb. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KPHL

This has to be one of the fastest Atlantic crossings for such an intense storm.

At least somebody is getting record snowfall.

The February record for the western half of CT was set just 10 years ago. At that time we were setting records for the -AO instead of the +AO now.

Parts of CT could challenge their all-time February record lowest pressure on Friday.

The Pacific Jet continues to set records.

Long Island could see higher gusts than that since it will be closer to the strongest LLJ near frontal passage. The warmer surface temperatures should really steepen the low level lapse rates for good mixing along and behind the cold front. Euro has highs in the low 60’s.

Areas around NYC are on track for their first sub 980 mb pressures since 10-29-17. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=18&network=NJ_ASOS&zstation=EWR&sdate=2017%2F01%2F01&days=1000&var=mslp&dpi=100&_fmt=js

At least we aren’t alone with the challenging snowfall situation. https://www.star.nesdis.noaa.gov/smcd/emb/snow/HTML/snow_extent_plots.html

This has been our default February pattern since 2017 as this Niña-like regime continues.

67 degrees in Atlantic City after the sun came out. http://wxweb.meteostar.com/meteogram/link.shtml?choice=KACY

While all the models have had a cold bias beyond 120 hrs, the GEFS has been much worse than the EPS.

I would much rather have a series of great KU events than a bunch of smaller ones adding up to 20 something. Our snowfall seasons have become more like a power hitter that either homers or strikes out a lot. So it leaves us open to slump years when it’s a struggle to just get on base.

The midrange 20’s snowfall seasons have vanished at places like BNL since the 93-94 winter. They used to be common before then. Snowfall distribution has become more extreme. Now snowfall is either over 30” or under 20”. https://www.bnl.gov/weather/4cast/MonthlySnowfall.htm

January finished with the 3rd most positive AO index for the month behind 1993 and 1989. Jan 1993...+3.495...1989....+3.106....2020...+2.419. Models continuing to forecast levels getting above +5. This would be near the all-time highest values. https://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/monthly.ao.index.b50.current.ascii.table
