Area Forecast Discussion National Weather Service Mount Holly NJ 619 AM EST Tue Jan 21 2020

SYNOPSIS. High pressure across the Ohio River Valley today will build eastward across the Mid Atlantic and northeast states Wednesday through Thursday. This high will weaken and retreat to the northeast Friday before a storm system moves across the Mid Atlantic and northeast states late in the week and into the weekend. This low will strengthen as it moves into the Canadian Maritimes early next week while high pressure builds to our southwest.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Possible for temps to drop by a few more degrees over the next hour or so, as winds have become clear and winds have diminished to less than 5 mph across much of the forecast area. However, lows for the most part are in the teens. Could have a few spots dropping to the single digits, but temps will rebound in the 7-8am timeframe.

Otherwise, high pressure over the Midwest will slowly build east into the Ohio and Tennessee Valleys throughout the day.

With high pressure in control, abundant sunshine with dry conditions are on tap for today. W-NW winds 5-10 mph. Highs will top off in the low to mid 30s throughout, and in the 20s in the southern Poconos.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM WEDNESDAY/. High pressure continues to build east tonight and will be over the Appalachians by daybreak Wednesday. Clear skies and light winds will allow for strong radiational cooling conditions, but there will also be WAA in the middle layers of the atmosphere. As a result, it will be a cold night, but not quite as cold as Monday night.

Lows will be in the teens to around 20.

LONG TERM /WEDNESDAY THROUGH MONDAY/. Quiet weather will begin the long term forecast, then unsettled weather returns for the end of the week into the weekend, then quiet weather is expected to return again early next week.

High pressure builds across the Mid Atlantic and northeast states Wednesday into Thursday. This will keep dry, quiet weather in the forecast. Temperatures will be cool and near normal for Wednesday, then warm above normal by Thursday as thicknesses increase.

The high pressure will begin to weaken and retreat to the northeast by Thursday night and Friday. The forecast remains dry through Friday, however, cloud cover will be on the increase in advance of the approaching storm system as a couple of short wave moves across the area.

The main focus of the long term forecast then turns to the storm system over the weekend. An occluding low pressure system will be lifting across the Mid-West and into the Great Lakes Friday into Friday night, while lifting a frontal system toward the Mid-Atlantic region. A secondary low is forecast to develop to our southwest across the central Appalachians Friday night, then lift to the northeast near our region Saturday, and strengthen and become the main low of the storm system. There are timing and placement differences with the development of this secondary low, and this will have an impact on the precipitation type. The GFS is faster and closer to the coast, while the ECMWF is slower and farther inland. A wintry mix is expected for areas along and north of I-78 starting Friday night and continuing through Saturday into Saturday night. Areas along the I-78 corridor may change over to all rain for a time Saturday, before changing back to snow by Saturday night. Areas farther north, especially along and north of the I-80 corridor will likely remain all snow during the event. Those areas that see all snow may end up with several inches of snow, while areas farther south could see a couple of inches along with some icing. Areas farther south of the I-78 corridor will likely remain all rain until Saturday night into Sunday as the precipitation changes to snow for many areas as colder air wraps around the low as it moves to the northeast. Any precipitation will begin to end later Sunday into Sunday night as the low pulls farther away from the area.

High pressure will build to our southwest early next week, while low pressure moves through the Canadian Maritimes. Winds will become gusty due to a tight pressure gradient between the low to our northeast and the high to our southwest, beginning later Saturday, and continuing through Monday. Dry weather will return to the forecast for Monday
