Area Forecast Discussion National Weather Service New York NY 351 AM EST Fri Feb 28 2020

SYNOPSIS. High pressure builds across the region through the weekend before sliding offshore into Monday. A weak frontal disturbance approaches the area from the west into Tuesday with a stronger low pressure system likely developing behind it by Wednesday. High pressure may return by Thursday.

NEAR TERM /THROUGH TONIGHT/. Blustery westerly flow will continue through tonight as the pressure gradient remains tight across the area. However peak gusts will be about 10 to 15 kt less than on Thursday. Wind speeds should decrease significantly by this evening and into tonight.

High temperatures today will be in the 30s to low 40s with lows in the 20s.

SHORT TERM /SATURDAY/. Dry and chilly conditions continue into Saturday as high pressure builds across the area and winds shift around to the northwest. Temperatures will remain below average for this time of year with highs on Saturday in the 30s.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. As the trough slides offshore, surface ridging slides into the region as the center of high pressure stays mainly to the south on Sunday and through Monday. Seasonable temperatures in the low 40s on Sunday gradually increase as surface winds shift to a more southerly flow by Monday with highs in the upper 40s and low 50s.

The unsettled week begins with a weak shortwave that approaches the CWA from the west by Tuesday. Increased moisture from southerly flow may result in a few showers as the shortwave passes through the day. Global models then diverge on a solution mid-week as a longwave trough enters the upper Midwest. The GFS has its typical progressive bias and phases a cutoff low in the Southern Plains with the shortwave rounding the base of the trough by Wednesday. This forces surface low pressure development over the mid-Mississippi and Ohio Valleys. The ECMWF keeps these two disturbances separate as the shortwave rounding the base of the trough stays a bit more to the north. Though the interactions between these systems vary between models, low pressure development to our west is likely by late Tuesday into Wednesday with a warm front moving in from the south through Tuesday night and the cold front pushing through by late Wednesday and into Thursday. This results in the chance of rain showers through most of the middle of the week. High pressure then looks to build back into the area by Thursday.

Temperatures over the week look to be generally well above average. With a dominating southerly flow ahead of the low pressure system, an increase in moisture accompanies warming temperatures. High temperatures will likely be in the middle to upper 50s through mid- week with temperatures possibly cresting 60 degrees in the city by Wednesday. Temperatures gradually cool with the passage of the cold front by late week.

AVIATION /09Z FRIDAY THROUGH TUESDAY/. Deep low pressure well north of the area will continue to remain nearly stationary through this evening.

VFR through the TAF period.

West winds generally 15 to around 20 kt with gusts 20-30 kt for the city terminals, with a few terminals closer to 10 kt with gusts to 20 kt overnight. The gusts will increase by 14z to 15z today with gusts generally at 25-30 kt. Gusts start to diminish by the early evening, and should end around 00z to 03z Saturday.

OUTLOOK FOR 06Z SATURDAY THROUGH TUESDAY. Friday night. VFR. W winds 5-10kt. Saturday. VFR. W/NW winds G20-25kt. Sunday. VFR. NW winds G15-20kt. Monday. VFR expected. Tuesday. Sub-VFR with a chance of rain.

MARINE. Gales has been extended through 17z today across far eastern ocean waters, elsewhere SCA is now in effect through tonight. Winds will decrease further tonight, but an advisory will be needed on the ocean as seas will remain likely above 5 feet through Saturday, with conditions marginal elsewhere.

High pressure moves over the waters Sunday night into Monday with winds and seas below SCA levels on all waters. Winds and seas look to approach SCA on Tuesday ahead of an approaching cold front.

HYDROLOGY. No hydrologic impacts are expected thru the middle of next week.

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

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
