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.

OUTLOOK FOR 18Z FRIDAY THROUGH MONDAY. Friday. VFR. W winds G25-30kt. Saturday. VFR. W/NW winds G20-25kt. Sunday. VFR. NW winds G15-20kt. Monday. VFR expected.

MARINE. A Gale Warning is in effect for all waters today and through early Friday morning as strengthening westerly winds increase to up to 40 kts and waves increase to 7 to 9 feet south of Long Island. Gale conditions may persist into Friday afternoon, particularly on the ocean, as the low continues to pull away from the region.

Winds and seas slowly diminish to below SCA conditions by Friday night and into Saturday for all waters, but marginal SCA ocean seas may linger into Sunday for the ocean waters.

HYDROLOGY. No hydrologic issues are anticipated for entire forecast period.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
