Area Forecast Discussion National Weather Service New York NY 928 AM EST Tue Jan 21 2020

SYNOPSIS. A large high pressure system covering the eastern two thirds of the nation will build over the area through Thursday, then retreat to the north on Friday. Low pressure will impact the region this weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Only minor adjustments were made to the forecast today to account for current conditions.

A 1040 high remains centered over the mid Mississippi/Ohio river valleys this morning. The high will continue to build towards the area today with winds diminishing. Temperatures very similar to yesterday, with highs around 30. The NBM was used with local adjustments. Clear to start, but some high clouds currently over the nrn Great Lakes begin to move into the lower Hudson Valley this morning, and then across much of the region by evening.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/. Some high clouds at times tonight, otherwise dry and continued cold with lows mainly in the teens and single digits. A blend of the MET/MAV was used. Light winds 5 kt or less overnight. The high builds over the area on Wednesday, with light winds and mostly sunny skies. Some cirrus possible at times. Increasing heights but a lack of deep mixing will keep highs in the 30s.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/. High pressure will remain in control resulting in dry weather with moderating temperatures as upper level ridging builds into the northeast. High temperatures on Thursday and Friday will be above normal, reaching the lower to middle 40s.

High pressure will retreat on Friday as a system over the midwest tracks towards the region Friday night. There is good agreement among medium range guidance showing an upper low lifting northeast from the Mississippi Valley with a surface low developing across the Mid Atlantic. Precipitation will overspread the area slowly late Friday night into Saturday morning. While there is good agreement in regards to timing and track of the system, there remains uncertainties regarding precip type especially this far out. The track and timing of the developing surface low will be key in deciding the precipitation type. Quicker development of the surface low would supply colder air at the low levels translating to more wintry precip. Have kept a mainly plain rain event with the possibility of some wintry precip away from Long Island.

The upper low then tracks towards the Mid Atlantic Saturday and over the region on Sunday which could keep clouds and precipitation in the forecast through the day. The upper low will then move east of the area early next week.

Temperatures Saturday through Monday will average slightly above normal.

AVIATION /15Z TUESDAY THROUGH SATURDAY/. High pressure builds from the west today and tonight.

VFR. Winds fluctuate between WNW and NNW with speeds around 10 kt or less. Light winds expected tonight and Wednesday morning.

NY Metro Enhanced Aviation Weather Support .

Detailed information, including hourly TAF wind component forecasts, can be found at: http:/www.weather.gov/zny/n90

KJFK TAF Comments: No unscheduled amendments expected.

OUTLOOK FOR 12Z WEDNESDAY THROUGH SATURDAY. Wednesday through Friday night. VFR. Saturday. MVFR/IFR in developing rain, possibly mixed across the interior. E winds 10-15G15-25 kt.

MARINE. Seas on the ocean were slightly higher than forecast, and will continue to subside in the northerly flow.

With high pressure in control through Thursday, winds and seas will remain below SCA criteria.

Ocean seas will gradually build late Thursday night through Friday as a system passes offshore. Seas continue to build on Saturday as low pressure develops. Winds will also increase to SCA levels by Saturday.

HYDROLOGY. A widespread precipitation event is becoming likely this weekend. Precipitation amounts remain uncertain at this time therefore it is still too early to determine what impacts may occur.

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

OKX WATCHES/WARNINGS/ADVISORIES. CT . None. NY . None. NJ . None. MARINE . None.

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.
