Area Forecast Discussion National Weather Service New York NY 134 PM EDT Fri Apr 10 2020

SYNOPSIS. Strong low pressure will track up into the Canadian Maritimes into this afternoon, while high pressure over the mid section of the country builds east. The high passes to the south Saturday night into Sunday morning. A complex low pressure system will then approach Sunday night and move across the area Monday into Monday night. High pressure follows through mid week with a weak frontal system crossing the area Wednesday night into Thursday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Forecast remains on track with just some tweaks in updating database to latest observations/trends. Lowered daytime max by a degree or so in most locations as diurnal warming has been hard to come by. Held firm with winds with observations essentially as expected thus far, with only a few locations seeing gusts at or just above 40 mph.

Deepening low pressure will track up through the Canadian Maritimes into this afternoon, while high pressure over the mid section of the country crawls east. This will keep the area in another day of gusty west winds with frequent gusts up to around 40 mph. A few higher gusts up to 45 mph will be possible, especially for the locations that typically gust a touch higher. Thus far any slightly higher gusts have been confined mainly to the higher elevations across the interior.

In addition, cyclonic flow and steep low-level lapse rates will result in mostly cloudy skies much of the time with some widely scattered showers this afternoon. These showers may briefly enhance wind gusts up to 45 mph.

Highs will be in the upper 40s inland to around 50 at the coast, which is about 5 to 8 degrees below normal.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Gusty W-NW winds will gradually diminish through the night with gusts up to 25 mph lingering into Saturday afternoon. Height rises following the departure of the upper low will allow for subsidence Friday night into Saturday with clear skies.

Lows Friday night will range from near freezing across upper portions of the Lower Hudson Valley and interior northeast NJ, to the mid and upper 30s at the coast.

Highs Saturday will rebound a bit into the lower and mid 50s. Still though a few degrees below normal.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. High pressure will pass to the south of the area Saturday night into Sunday morning, giving way to a deepening storm system over the Lower Mississippi Valley. The latter of which has the potential to bring a period of moderate to heavy rain and strong southerly winds to the area on Monday. Gusts of 40 to 50 mph will be possible along with embedded thunderstorms. Rainfall amounts could exceed an inch, especially north and west of the NYC metro due to orographic enhancement in a strong S/SE flow. Any lingering showers taper off Monday night.

High pressure builds in for the mid week with a weak frontal system possibly impacting the area late Wednesday night into Thursday.

Near normal temperatures on Sunday, above normal Sunday night through Monday night, and closer to normal thereafter.

AVIATION /17Z FRIDAY THROUGH WEDNESDAY/. Deep low pressure continues to track into the Canadian Maritimes as high pressure builds to the west.

VFR is expected through Saturday morning. A few passing light showers are possible for the remainder of the afternoon.

The 6-8 kft ceilings scatter tonight.

Winds remain W/NW into the evening, with speeds 15-25 kt and gusts 25-35 kt. A few higher gusts are possible at times. Winds diminish tonight, but gusts should continue 25-30 kt around NYC metro into the overnight. 20-25 kt gusts are expected Saturday morning.

OUTLOOK FOR 18Z SATURDAY THROUGH WEDNESDAY. Saturday afternoon. VFR. WNW winds 15G20-25kt. Sunday. VFR. Sunday night and Monday. MVFR to IFR (or lower) in rain. S winds 20-30G30-40 kt. Strongest winds along the coast. Chance of LLWS. Monday night. VFR with a cold frontal passage. W winds G15-20kt. Tuesday. Mainly VFR with a low chance of afternoon MVFR showers. W winds G15-25kt. Wednesday. MVFR possible in showers.

MARINE. Gale warning remains up on all waters today and has been extended into the first half of tonight.

Gales will return to the waters this morning as another shot of cold air moves across the waters and strong low pressure lifts up into the Canadian Maritimes.

SCA gusts for all waters Saturday. Sub-SCA conditions Saturday night into Sunday as high pressure moves across the waters. SCA gusts return for all waters late Sunday night with gales likely on all waters Monday as another strong frontal system impacts the area. There is the potential for storm force gusts on the ocean waters with seas building in excess of 12 ft.

Conditions gradually improve Monday night into Tuesday as the storm system lifts to the north.

FIRE WEATHER. Rainfall from yesterday should help to limit fire growth potential today despite strong winds and low afternoon RH (30 to 40 percent). This may enhance fire spread and will really depend on how fast the surface ground layer dries out. Additionally, there will be widely scattered showers across the area.

With further drying on Saturday, could be a day of concern as there will be more potential for fire spread, with W winds still gusting to around 25 and minimum RH 20 to 30%.

HYDROLOGY. QPF in excess of an inch is possible Sunday night into Monday which could at least result in minor poor drainage flooding. Higher amounts will be possible across the interior due to orographic lift in a strong S/SE flow.

EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is undergoing its final stages of testing, and is operating at full 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.
