Area Forecast Discussion
National Weather Service New York NY
1255 PM EST Thu Feb 27 2020
.SYNOPSIS...
Low pressure stalls and pivots well north of the CWA through
Friday. High pressure builds across the region through the
weekend, then slides east on Monday. A slow frontal system will
then impact the area Monday Night and into the mid- week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
The forecast is on track this aftn. Peak gusts of around 45 kt
have been reported today. The wind advy remains in effect until
8 pm. With strong CAA in the CWA, temperatures will gradually
drop through the day and into this evening. Clearing skies from
the encompassing dry airmass will promote mixing of stronger
winds aloft down to the surface during the day.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
The longwave trough over the Great Lakes and Northeast will
remain in place as the low pressure well to our north occludes
and stalls. Strong gusty winds will gradually decrease through
the night and into Friday morning. Conditions will continue to
remain dry as CAA brings high temperatures back to average to a
few degrees below average generally in the middle to upper 30s.
&&
.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Quiet and colder weather through Sunday as high pressure builds
across the region. A gusty northwesterly flow combined with
temperatures in 30s to near 40 during the day and upper teens to low
20s at night will make conditions feel even colder over the weekend.
Temperatures will moderate by Sunday night as high pressure slides
east and winds go around to the southwest.
High pressure slides east on Monday, with a slow moving frontal
system approaching the region Monday Night and affecting the region
into Midweek. This will bring an increasingly moist and mild airmass
to the region, but also unsettled weather in the form of periods of
rain as waves of low pressure track along the slow moving "cold"
front. Potential for a wintry mix across the interior, Monday into
Monday Night, otherwise thermal profiles suggest rain for the
remainder of the event. Temperatures will moderate from a few
degrees above seasonable Monday to potentially well above seasonable
by mid week.
&&
.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
A cold front has pushed east of the terminals as deep low
pressure tracks north of the region.
Mainly VFR through the remainder of the TAF period with
ceilings lifting to 4-5 kft before scattering.
West winds 20-25 kt with gusts 30-35 kt through afternoon. A
few higher gusts are possible this afternoon, especially at the
city and coastal terminals. Some low level wind sheer will be
possible through the afternoon.
