Area Forecast Discussion National Weather Service New York NY 718 PM EST Sun Jan 19 2020

SYNOPSIS. Low pressure moves farther away from the local region tonight, going through Newfoundland. Meanwhile, a strong high pressure area will continue to build in from the North Central US. This high will continue to gradually build in much of this week. The high pressure area weakens Thursday night into Friday with low pressure approaching into next weekend.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/. The trough upstream with associated snow shower activity using tracking of its movement, around 25 kts to the southeast, takes the shower activity to mainly interior parts of the region for this evening before 03Z. With the dry air in place as seen from the current dewpoint depressions, the showers may not hold together and break apart as they move in. So have low pops for snow showers and some brief snow flurries as well for this evening in the forecast before 03Z.

A low level and surface trough across New England and the mid Hudson Valley should slowly sag southward this evening, with mostly cloudy skies and few light snow showers or snow flurries. Expect mostly clear skies overnight after passage of a vigorous mid level vort max moving across southern New England, marking the arrival of colder air.

With winds staying up most of tonight, sided with slightly higher of the MOS guidance lows tonight, from the mid teens inland to the lower 20s along the coast and in the metro area. Minimum wind chills will reach 10 above in NYC, single digits most elsewhere, and near zero well inland N-NW of the city.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/. Gusty N flow will continue into Monday as another mid level vort max swings by. Temps will be below normal especially at night, with highs on Mon from the upper 20s inland to lower 30s coast/metro, then lows Mon night from the single digits inland to the teens most elsewhere to lower 20s only in NYC. Wind chills daytime Mon will be about 10 degrees colder than air temps, then during Mon night fall to near 10 above in NYC, single digits elsewhere in metro/coastal sections, and near zero across most of the interior.

LONG TERM /TUESDAY THROUGH SUNDAY/. Quiet for much of the period with the influence of high pressure until next weekend with a high moving farther northward and approaching low pressure from the south.

For Tuesday and going through Thursday, an air mass from the North Central US will be building into the region. Strong high pressure builds in gradually from the west Tuesday through Wednesday, moving overhead Wednesday night into Thursday. This will make for light and variable winds with the very weak pressure gradient. The high weakens Thursday night into Friday allowing for more clouds to move into the region as subsidence weakens.

Dry weather is expected through Friday. Next chances for precip arrive Friday night with increasing chances of precip for next weekend.

Next weekend, forecast has gusty E-NE flow and some potential heavy precip. Track of low center moves near region, either directly over the region or offshore. A lot of uncertainty with this event being a week away especially with the speed and position of the low center. Precip type will be highly dependent on track. Overall looking at the ECMWF, GFS, and Canadian models, the center of the low could track close enough to have some warming aloft. The retreating high going farther northward signals some cold air damming potential so with temperatures at 850mb getting potentially a few degrees C above freezing, could have a wintry mix Friday night into early Saturday changing to rain Saturday from south to north. Depending on how the low evolves next weekend, could have some wintry precip as well as Saturday night into Sunday. Have this as a rain and snow mix across the interior with a forecast of having the low move east of the area with colder air working into the area on the backside of the low.

Regarding temperatures, the air mass for Tuesday through Wednesday will be from the North Central states. Winds will be northerly but gradually decreasing as the center of the high moves in closer to the local area. The decrease of northerly winds will gradually lessen the cold air advection allowing for the air mass to moderate by midweek. Conveyed a gradual warmup for daytime highs each day Tuesday through Thursday going from several degrees below normal to several degrees above normal. There is more weight towards MOS for all temperatures Tuesday through Tuesday night as well as Wednesday night and Thursday night. The nighttime temperature use more MOS to convey radiational cooling conditions with more vast range of lows between NYC and rural sections.

AVIATION /00Z MONDAY THROUGH FRIDAY/. High pressure gradually builds to the west through Monday Night.

VFR. A few flurries or isolated -SHSN cannot be ruled out mainly across the Lower Hudson Valley and southern CT through this evening.

NW winds around 15ktg20-25kt through Monday afternoon for NYC/NJ metro terminals. Gusts will likely be occasional for outlying terminals overnight, but they should become frequent around 20 kt once again Monday morning. The wind direction should average right of 310 magnetic through the period. Winds and gusts subside for Monday evening push.

OUTLOOK FOR 00Z TUESDAY THROUGH FRIDAY. Monday Night-Friday. VFR.

MARINE. The waters will remain in a gusty NW-N flow regime into Monday. SCA remains in effect for all waters, and has been extended through Mon afternoon for NY Harbor with near shore gusts up to 25 kt now expected into daytime Mon, also into early Mon eve for the eastern ocean waters where 5-ft seas may linger a little longer.

A weak pressure gradient in place across the area waters with below SCA conditions Tuesday through Friday. Conditions trend upward for winds and seas Friday night as low pressure approaches from the south and west and the pressure gradient increases between the low and the retreating high well north of the region. Marginal SCA level seas develop on the ocean Friday night. SCA becomes more likely for most of the waters on Saturday as the low pressure system approaches closer and deepens slightly with a further increase of the pressure gradient.

HYDROLOGY. There is potential for widespread precip next weekend. Still it is too soon to tell what exact hydrologic impacts there will be due to uncertainty with precip types and amounts.

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.
