Area Forecast Discussion National Weather Service New York NY 1003 AM EST Sun Dec 15 2019
SYNOPSIS. High pressure builds in from the west today as low pressure continues to track well to the north. High pressure briefly builds over the region tonight, then drifts offshore Monday. A low pressure system impacts the region Monday through Tuesday, departing to the northeast Tuesday night. High pressure builds into the region on Wednesday and remains over the area through the end of the week.
NEAR TERM /THROUGH TONIGHT/. Forecast on track with just a few minor adjustments to reflect latest observations. With the cyclonic flow remaining across the northeast clouds have begun to move back into the western zones. So increased cloud cover through this morning, as drying should begin this afternoon with the ridge building. Also adjusted dew points and temperatures, which were running higher than forecast.
The deep upper closed low that affected to the region Saturday will continue to track through eastern Canada as the flow across the area becomes zonal. Snow streamers were coming off the eastern Great Lakes in the strong west flow. The flurries should remain west of the region, however, would not be too surprised if a few made it into the lower Hudson Valley. Meanwhile the next shortwave to affect the region will be amplifying into the intermountain southwest. With a zonal, progressive flow, this shortwave will quickly translate eastward. However, there remains uncertainty as to the timing of this system.
Meanwhile weak surface ridging builds into the area today as the developing surface low tracks through the southern plains and into the lower Mississippi Valley. With a strong pressure gradient between the departing low to the north and high pressure to the west, strong and gusty westerly winds are expected. These winds and gusts will diminish early this evening as the surface high builds into the area. The high will be over the area through tonight, with the center of the high shifting off the Mid Atlantic coast toward morning. The high will keep the frontal system suppressed to the south with precipitation remaining to the southwest of the area 12Z Monday.
SHORT TERM /MONDAY/. While the guidance has come into a little better agreement with the shortwave tracking toward the area, there still remains uncertainty with the track of the low. The latest trend has been a shift a little farther to the south. And later guidance may continue this trend or even shift the low back to the north. The uncertainty will have impacts to the timing and type of precipitation across the forecast area.
With the latest trends have held off the timing of the precipitation as the high shows weak signals of damming, keeping cold air across the northern tier. So, will have likely probabilities after 18Z and only across the far southern zones with low end chance probabilities reaching much of the area by later Monday afternoon.
With cold air in place precipitation will be in the form of light snow. And then with warmer air moving in along the coast, especially aloft, a mix of rain, snow, and sleet will be possible late day. There may even be pockets of light freezing rain across northeastern New Jersey and into northern portions of New York City.
LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. STORM SYSTEM MONDAY NIGHT THROUGH TUESDAY.
Timing and placement differences remain with the track of the low through Tuesday night with the GFS a little quicker and farther north than the ECMWF. Thus confidence is on the low end with precipitation types across the region. And the NAM was showing colder lower levels as a warm layer moves in aloft, with a strengthening warm frontal boundary. So, used a blend for precipitation types Monday night through Tuesday. With the possibility of colder surface air remaining Monday night into Tuesday, there may be more freezing rain closer to the coast than currently forecast. While inland may be predominately freezing rain.
The low will be tracking well east of the area Tuesday night with the precipitation quickly ending. Drying conditions are expected by later Tuesday night as the low deepens and accelerates northeast to eventually southeast of Nova Scotia by early Wednesday.
For the rest of the long term, high pressure starts to build back into the region on Wednesday and will remain over the area through the end of the week. Expect dry conditions with temperatures below normal. Low pressure may impact the area over the weekend.
AVIATION /15Z SUNDAY THROUGH THURSDAY/. Strong low pressure tracks north through eastern Canada today, with weak high pressure building into the region tonight. A weak area of low pressure approaches the region Monday.
VFR through Monday 12z.
Main concern will be gusty W winds, sustained 20-25ktG30-35kt today, with an isolated peak gusts to 40 kt possible. Winds and gusts gradually subside through the evening push, diminishing late tonight.
OUTLOOK FOR 12Z MONDAY THROUGH THURSDAY. Monday. MVFR/IFR conds in light snow/wintry mix becoming likely for NYC/MJ metro terminals in the afternoon. Monday night. IFR or lower likely. NYC metros and coastal terminals, wintry mix gradually changing to plain rain late. KEWR/KTEB/KBDR could see freezing rain linger into early Tue morning push. KHPN/KSWF wintry mix, including freezing rain. Tuesday. IFR or lower conds. Wintry mix, possibly changing back to all snow at KSWF before ending. Rain at NYC/NJ metro and coastal terminals, possibly changing to wintry mix before ending late. N gusts to 20kt developing Tue afternoon. Tuesday night. VFR. NW winds G20kt NYC metros/KISP mainly eve. Wednesday. VFR. NW winds G25kt mainly afternoon. Thursday. VFR.
MARINE. No changes to the winds and seas at this time.
Gale force wind gusts today, subsiding this evening, and falling below SCA by late tonight. Ocean seas will be a bit slower to respond with residual s/se swells, but should fall below SCA from w to e through Monday morning.
Sub-SCA condition expected through Tuesday morning, with SCA conditions becoming increasingly likely late Tuesday, and then likely all waters Tuesday Night through Thursday. Potential for a period of gale conditions on the ocean waters Wednesday Night with passage of an arctic front.
HYDROLOGY. Remaining flooding concerns are for the larger stem rivers in CT with a combination of the recent rainfall and melting snow to the north.
Another significant precipitation event is likely Monday through Tuesday, with liquid equivalent QPF of 0.5 to 1.25 inches possible. There is uncertainty in this amount given uncertainty in the track of the low and frontal positions.
EQUIPMENT. NYC NOAA Weather Radio Station KWO35 (162.55 MHz) is still operating at reduced power.
