Area Forecast Discussion National Weather Service New York NY 1231 AM EST Wed Jan 22 2020

SYNOPSIS. High pressure will dominate across the northeast and id Atlantic regions through Thursday, then retreat to the north on Friday. Low pressure will impact the region this weekend.

NEAR TERM /UNTIL 6 AM THIS MORNING/. Just a few slight adjustments based on latest observations, mainly with regard to temps and dew points. Also a slight adjustment with regard to high level clouds, which completely move out of the area a few hours later than previously advertised. Otherwise the forecast is on track as these slight adjustments will not have any sensible impacts on temperatures, etc.

Surface high pressure will remain across the area overnight. An upper level trough along the eastern seaboard was weakening and moving into the western Atlantic, as heights slowly rise across the forecast region. High level moisture with this trough and high clouds across the region will be moving out over the next few hours as the trough shifts offshore. Overnight there will be good radiational cooling conditions once again with the outlying areas falling into the teens and some single digits in the normally colder locations.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM THURSDAY/. Heights continue to rise through Wednesday as a ridge builds into the east coast. The ridge will then remain through Wednesday night. High level moisture will move back into the area Wednesday night as the ridge weakens somewhat and moistures spills over the ridge. Meanwhile surface high pressure remains across the area. Weak warm advection sets up late tonight and continues through Wednesday and Wednesday night. Temperatures will be modifying Wednesday and Wednesday night.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/. High pressure will be overhead on Thursday with dry weather, sunshine mixed with some cirrus, and high temperatures generally in the mid 40s. The dry weather continues on Friday with high pressure in control. It's shaping up to be similar to Thursday regarding sky conditions and temperatures.

A closed 500mb low moves through the Ohio Valley Friday night and eventually tracks over us late Saturday night. Associated surface low shifts NE from the Mid-Atlantic Saturday morning and passes through or nearby late Saturday night. Global models are in decent agreement with the track and timing of the storm, but differ with the thermal profile. PCPN chances begin late Friday night with PCPN becoming likely for all areas by the end of Saturday morning. Chances then lower Saturday night into Sunday morning with chances still remaining into Sunday afternoon with a cyclonic flow aloft. PCPN type will be mainly rain for coastal areas with a wintry mix inland. Based on an average of model thermal profiles, it appears that even the coldest spots would see a complete changeover to rain at some point given forecast freezing level heights. This of course is subject to change as we're still 4 days away from the event and the energy aloft driving the storm is just arriving into better RAOB sampling tonight into tomorrow.

High pressure builds in behind the storm with dry weather for Monday and Tuesday. Highs both days about 5 degrees above normal.

AVIATION /06Z WEDNESDAY THROUGH SUNDAY/. High pressure builds and remains in control into Wednesday and through Wednesday night.

VFR. Winds continue to diminish and decrease further to less than 5 kt overnight, becoming calm at many outlying terminals. Winds will remain light into Wednesday morning, and then will be west and southwest into Wednesday afternoon at around 5 kt.

OUTLOOK FOR 0Z THURSDAY THROUGH SUNDAY. Wednesday night-Friday night. VFR. Saturday-Saturday night. MVFR/IFR in developing rain at the coast, mixed precipitation across the interior. E winds 10-15G15-25 kt diminish overnight. Sunday. MVFR/IFR possible in lingering showers. Rain/snow mix possible in any showers across the interior.

MARINE. A weak pressure gradient remains across the forecast waters through Wednesday night as high pressure dominates. Winds and seas will remain below advisory levels.

Tranquil conditions on the waters continues Thursday and Thursday night with a high pressure ridge over the region. Winds and seas increase on Friday and Friday night in advance of a storm system that will approach from the SW. Seas on the ocean could build to 5 ft by the end of the day Friday, but more likely Friday night. SCA conds then likely on Saturday for all waters as the low passes through or nearby. Winds on the back side of this storm so far do not appear to be strong, but 25 kt gusts will still be possible Sunday morning on the ocean. Ocean seas will take some time to subside, so 5ft or greater seas on the ocean through the day on Sunday.

HYDROLOGY. Dry weather is expected through Friday.

A widespread precipitation event is 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.

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.
