Area Forecast Discussion National Weather Service Mount Holly NJ 636 AM EST Sun Feb 23 2020

SYNOPSIS. High pressure over the area moves offshore late Sunday and Sunday night. Low pressure develops over the Midwest and lifts to the northeast for the start of the work week. Several waves of low pressure will then impact the area through the end of the week until a strong cold front passes through the region. Arctic high pressure returns next weekend.

NEAR TERM /THROUGH TONIGHT/. 630 AM Update . Forecast is on track. No update required at this time.

Prev Discussion-> Surface high pressure will slowly head east this afternoon with a weak mid-level wave moving overhead. The wave is currently located over the Great Lakes with only some cirrus forming in response. This afternoon 850 mb temperatures stay around 2 degrees C, but increased mixing will likely equate to a couple of degrees warmer than yesterday (or mid 50s for most of the region). Dewpoints will also likely mix out again today, as has been the case for the last several days, thanks to PWATs remaining around a tenth of an inch. A weak sea breeze will then move inland this evening resulting in a slight backing of the winds and increase in moisture.

SHORT TERM /MONDAY/. This evening a weak sea breeze will stall around the PA/ NJ state line with mostly clear skies. The back edge of the wave will then approach the area with the GFS, NAM, and RAP indicating a transient mid-level deck moving across the area.

Monday, a closed low will be heading east across the central United States with surface high pressure now offshore. The wave will then open up near Missouri Monday evening. As of current, it appears the near term will remain precipitation free as the dry continental air mass will take time to dislodge. Highs Monday will be in the upper 50s.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Expect an active week with several disturbances across the the Mid Atlantic followed by a final cold front late in the week bringing an arctic airmass to the region.

The high pressure from the weekend will be sliding off shore as a closed low tracks into the Ohio Valley region. This will bring warm air advection and rainfall into to the region in the form of a warm front on Tuesday. Warm air advection continues under modest southerly flow Tuesday night before a second strong low pressure system closes off over the great lakes and tracks through the Saint Lawrence Valley. Trends in the 12z guidance yesterday and the 00z suite this morning were to weaken a northern stream low up near the Hudson Bay which leads me to believe in the surface low that will affect our region to be more of the Saint Lawrence Valley origin rather than a potential coastal low setup. This is pretty much the going consensus now for the GFS/EC/GEM and their ensembles.

Wednesday and Wednesday evening will likely be a washout with widespread rainfall over the region. Anticipate on the order of one half to an inch of rain with could be locally heavy at times. As the low deepens to our north and west an intense dry slot pushes into eastern PA and all of NJ Thursday morning. The soundings are showing a fairly classic drizzle setup so I've changed the precip type forecast for Wednesday to be more drizzle than rain and with no saturation in the icing layer we shouldn't expect any wintry precip.

Behind the low, a cold front pushes through the region Thursday afternoon returning temperatures closer to normal, with highs generally in the 30s in the Poconos, and otherwise in the low to mid 40s, possibly approaching 50 in southern Delmarva.

A stronger cold front then passes through Thursday night into Friday morning bringing an Arctic airmass down into New England and the Mid- Atlantic. While dry, we should see temps falling quite a way below normal heading into and over the weekend.

AVIATION /12Z SUNDAY THROUGH THURSDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . VFR. Southwest wind 5 to 10 kt. High confidence.

Tonight . VFR. Southwest wind 5 knots or less, becoming south as a weak sea breeze moves inland. A weak wave will also translate east bringing a ~7/8kft deck across the terminals. High confidence.

Monday . VFR with increasing cloud cover through the day. S/SW wind 5 to 10 knots. No significant weather expected.

Outlook .

Monday night . Mainly VFR, with MVFR ceilings late. A chance of rain. South wind 5 to 10 knots. Medium confidence on timing and coverage of any rainfall.

Tuesday . MVFR with periods of IFR possible in rain. Southeast wind 5 to 10 knots. Medium confidence.

Tuesday night through Wednesday Night . Generally IFR improving to MVFR as rainfall clears the region. Winds light and variable Tuesday night becoming east 5-10 knots Wednesday.

Thursday . Generally MVFR improving to VFR. West winds 15-20 kt with gusts up to 25 kt.

MARINE. Sub- SCA conditions expected with seas generally running 2 to 4 feet. Westerly winds becoming southerly around 10 knots.

Outlook .

Sunday night through Monday . Sub-SCA conditions expected. Wind gusts up to 15 kt. Wave heights up to 3 feet

Monday night and Tuesday night . Wind gusts to 20 kt. Wave heights up to 4 feet. Rain expected Tuesday.

Wednesday and Wednesday night . SCA conditions likely by Wednesday night with wind gust up to 25kts and wave heights increasing to 4 to 7 feet. Rain expected Wednesday night.

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.
