Area Forecast Discussion National Weather Service New York NY 1017 AM EST Fri Dec 6 2019
SYNOPSIS. A cold front approaches from the Great Lakes this afternoon, passing through the area this evening. High pressure will follow for Saturday and then build offshore on Sunday. A frontal system will impact the area for the beginning of next week.
NEAR TERM /UNTIL 6 PM THIS EVENING/. A northern stream shortwave trough will send low pressure over the Great Lakes this morning quickly east, passing to the north late this afternoon into early this evening and dragging a cold front through the region.
Ahead of the front, a tightening pressure gradient will result in a gusty SW flow by afternoon. Gusts of 30 to 35 mph will be possible along the immediate coast, especially across LI.
Limited moisture and upper dynamics will limit precip with the frontal passage, but a few snow showers/flurries possible across the interior Tri-State this morning into early afternoon, and then potential for scattered showers across LI and SE CT late this afternoon into early evening ahead of the cold front as it interacts with more moisture. No snow accum expected across Interior, with less than a tenth of an inch of rainfall for coastal areas.
For the most part, the day will be cloudy with temperatures in the mid-upper 30s Interior to lower to mid 40s for city/coast, which is right around normal.
SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Cold front passes through early this evening along the coast with a brief shower possible, otherwise conditions will be dry with a gusty NW flow the first half of the night.
The gusty winds will keep temperatures from dropping too much below normal, with lows by daybreak Saturday ranging from the mid 20s across the interior, to the around 30 at the coast.
High pressure builds in from the west on Saturday with diminishing NW winds and cold conditions. Highs will be about ten degrees below normal in the 30s.
LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. The center of high pressure will move over the area Saturday night. This will mean light winds and mainly clear skies, leading to a pretty good radiational cooling night, especially in the outlying areas as usual. Went a couple of degrees below guidance for Saturday night, and several degrees below for Pine Barrens of Long Island. Lows will be in the 10s and 20s.
Thereafter, the forecast area will be on a warming trend as the center of high pressure moves offshore Sunday morning. Veering winds in forecast soundings as a warm front lifts well north of the area will mean warm advection for Sunday and highs warmer than Saturday, but still below normal for this time of year, ranging from the middle 30s inland, to the middle 40s along the coast.
A complex frontal system will impact the area at the beginning of the new work week as an upper level shortwave over the Northern Rockies dives south into the mid-West Sunday into Monday, which phases with a southern stream system Monday night into Tuesday, inducing a surface low that tracks over the Great Lakes and then into southeastern Canada into Tuesday. This will allow a cold front to approach through Tuesday. That will mean a continued southerly flow and progressively warmer temperatures Sunday through Tuesday. By Tuesday, highs will be well above normal, in the 50s region-wide. There is a slight chance that some precipitation moves in early Sunday night for western sections of the forecast area. If it does, it may be cold enough for a wintry mix, including some freezing rain across the Lower Hudson Valley. However, it is too far out at this time for any certainty in precipitation types, and if it does occur, it is expected to be brief. From late Sunday night through Tuesday, it should be warm enough for plain rain for the entire forecast area.
There is the potential for moderate to heavy rain from Monday through Monday night as there looks to be a sub-tropical connection south of the high that comes up northward on its west side. From Sunday night through Tuesday night, both the ECMWF and the GFS have over 2 inches of rainfall across portions of the area, with a widespread 1 to 2 inch rainfall for the entire forecast area. PWATs of over an inch are also noted in the GFS (as well as NAM coming up the east coast Sunday night). There is still a great deal of uncertainty with where the heaviest rain would actually set up and with the timing. The one good thing is that this will be a long duration event.
The cold front pushes offshore Tuesday night, ushering in a colder air mass for Wednesday, with highs in the 30s to around 40.
AVIATION /15Z FRIDAY THROUGH TUESDAY/. VFR as high pressure settles south early this morning. A cold front will pass this evening.
There is a chance for a mix of light snow and light rain across the interior Lower Hudson Valley terminals and across most of Connecticut terminals, this afternoon. TEMPO group for KSWF and KGON to account for this potential but confidence in occurrence is on the low side.
Fairly high confidence in winds backing SW and increasing to 10-15G20-25kt this afternoon. Gusts to 30 kt are possible along south coastal locations. Timing of fropa roughly 00Z NYC metros and 01Z-02Z east, with winds shifting WNW at first and then right of 310 mag toward midnight.

OUTLOOK FOR 15Z SATURDAY THROUGH TUESDAY. Saturday and Sunday. VFR. Sunday night and Monday. Rain showers likely with MVFR or lower conditions. Tuesday. MVFR or IFR in rain, with conditions improving late at night.
MARINE. A gale warning remains in effect for the ocean waters with SCA conditions elsewhere.
Winds ramp up quickly late this morning into this afternoon ahead of an approaching cold front. The cold front passes through the waters this evening. Gusts of 30 to 35 kt are expected this afternoon into tonight, diminishing to below SCA toward daybreak Saturday as high pressure builds in from the west.
Winds may briefly reach 25 kt Sunday night on the ocean waters. An approaching frontal system will allow southerly flow to increase late Monday morning into the afternoon, with gusts 25-35 kt into Monday night for all coastal waters except the western sound and harbor. Winds diminish late Monday night, with 25 kt gusts still possible over the waters through the day Tuesday.
Waves will remain below 5 ft through Sunday night, but build to 5 ft on the ocean waters by late Monday morning/early Monday afternoon. Waves continue to build on the ocean to 5 to 12 ft by Tuesday afternoon. Waves of 5 to 8 ft are possible across the extreme eastern portion of the eastern sound, with 5 ft waves more likely across this area Tuesday. Waves diminish Tuesday night.
HYDROLOGY. No significant liquid equivalent is forecast through Sunday.
A significant long duration rainfall event is possible beginning late Sunday Night through Tuesday night.
EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.
The KOKX WSR-88D radar will be out of service until approximately 12/7 due to the refurbishment of the transmitter. This work is part of the NEXRAD Service Life Extension Program.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
