Area Forecast Discussion National Weather Service New York NY 642 PM EST Tue Jan 28 2020

SYNOPSIS. A weak cold front moves across tonight with high pressure building in from Southeast Canada for late tonight through Wednesday night. High pressure Thursday and Friday will yield to low pressure passing offshore over the weekend. After fair weather on Monday, a weak system may produce some rain on Tuesday.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Increased clouds for the next few hours based on satellite. Otherwise the forecast is on track. NW flow will be gusty at times into this evening towards the coast with a cold front moving across. There will be abundant clouds to start tonight ahead of the front with an accompanying mid level shortwave and its positive vorticity advection moving across the area. High pressure builds in late tonight behind the front and this will bring in an airmass from Southeast Canada, with a slight decrease in winds and decreasing clouds.

Lows overnight into early Wednesday morning are expected to be a general range from around 20 for outlying rural locations and the interior to near 30 for NYC. This is consistent with a consensus of MOS.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. For Wednesday, expecting the clouds to further decrease as the center of high pressure moves closer to the local region. In the mid levels, a ridging trend with slow steady height rises is evident in the numerical weather prediction models.

NW winds will be around 5 to 10 kt but not expecting much in the way of gusts as the pressure gradient will be relatively weak. The ridging aloft will promote subsidence, allowing for much more sunshine. However, model soundings show vertical mixing heights will be limited to around 925mb. Highs are generally expected to be in the upper 30s to lower 40s, a consensus of MOS.

For Wednesday night, the combination of clear skies and light winds will provide ideal radiational cooling conditions. Took the relatively lower MET MOS for temperatures, which will bring lows for some interior and rural locations near 10 to 15 degrees while NYC will be in the mid to upper 20s.

LONG TERM /THURSDAY THROUGH TUESDAY/. The models were in good agreement in the extended, so the NBM was generally used, with some local adjustments to temperatures made. High pressure builds into the Northeast on Thursday, providing fair weather across the forecast area. A moisture starved upper level system passes south of the region Thursday night into Friday. The light precipitation associated with this is progged to stay well south of the area. There could be some cloud development around 3000 ft late in the day however with a light southerly flow aloft and weak lift. Dry again on Friday, but increasing clouds are likely as low pressure begins to organize over the Southeast. The modeling takes the low east of the area, leaving the forecast area on the wrn fringe of the system Friday night and Saturday. The current track would be mainly snow due to the thermal profiles, but little in the way of liquid equivalent. Rain or snow has been included in the forecast to incorporate track and timing uncertainties due to the long lead time. The model blend approach of an H5 trough on Sunday has led to inclusion of low probabilities for Sunday. If a deterministic approach was used, the forecast would have been kept dry per the 12Z data. A quick warmup ensues for the beginning of the week with ridging building into the area. A shortwave riding the ridge could produce some rain on Tuesday. There is likely to be some feedback from convection as the feature emerges from Texas and tracks newd, so confidence in the details are low this far out.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. A large area of high pressure gradually builds in from the west tonight and Wednesday.

VFR. BKN-OVC clouds 4-6 kft this evening should gradually scatter and clear later tonight. Few if any clouds are expected during the day Wednesday.

NW winds prevail 8-13 kt before diminishing some later tonight. These NW winds persist through the day Wednesday, 10-13 kt.

OUTLOOK FOR 00Z THURSDAY THROUGH SUNDAY. Wednesday night through Friday night. VFR. Saturday. MVFR or lower possible in rain or snow. Sunday. Mainly VFR. Slight chance rain or snow. NW gusts 15-20 kt possible.

MARINE. Marginal SCA conditions will be in place across the ocean into this evening with a few wind gusts to 25 kt possible at times. Most gusts are expected to be near 20 kt on the waters this evening. Ocean seas will be 2 to 4 ft. Winds subside late tonight and through midweek with high pressure moving in from the north. Conditions are expected to be well below SCA criteria.

Winds and seas will remain below Small Craft Advisory levels Thursday into early Saturday. There is then the potential for advisory conditions, primarily on the ocean, into Monday depending on the track and intensity of low pressure.

HYDROLOGY. No hydrologic impacts are expected through Tuesday.

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

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.
