Area Forecast Discussion National Weather Service Mount Holly NJ 625 AM EST Sat Dec 7 2019

SYNOPSIS. High pressure will build across the Mid Atlantic and northeast states today and tonight, before shifting offshore on Sunday. A warm front is expected to lift northward across the area on Monday, followed by a cold front Tuesday into Tuesday night. High pressure builds back across the Mid Atlantic region Thursday into Thursday night, before shifting offshore through Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Quiet but cold weather expected for today. High pressure is building into the region out of the Midwest and will be directly overhead by this evening. Main point of interest today will be temperatures several degrees below normal behind yesterday's cold front, with a sharp trough overhead. A weak upper level disturbance, also tracking out of the upper Midwest, may lead to a period of increased high clouds this morning or early afternoon, but large scale subsidence associated with the high pressure will yield a dry day. Northwest flow continues behind the front but wind speeds will be on the light side without much of a gradient.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/. Strong high pressure remains overhead tonight. Winds will go nearly calm and the air is very dry, and with mainly clear skies in place it should be a very good night for radiational cooling. The upper level trough will push off to the east overnight and temperatures aloft will start to inch up slightly, but surface temperatures should drop quickly after sunset as the boundary layer decouples. Expecting one of the colder nights of the season so far with many areas dipping into the low to mid 20s and some teens to the north.

LONG TERM /SUNDAY THROUGH FRIDAY/. Quiet weather begins the long term period Sunday, then unsettled weather returns for the first half of next week, then quiet weather returns for the end of next week.

High pressure shifts offshore on Sunday, but the weather will remain dry through the day, although clouds will increase late in the day Winds may be a little gusty at times during the day Sunday, but gusts should remain mostly 15 to 20 mph, with occasional high peak gusts around 25 mph.

As we move into Sunday night, a warm front is expected to be lifting north toward the area, then lift across and through the area during the day Monday. At the same time, there will be multiple short wave/vorticity impulses moving across the area starting late Sunday night and continuing through Monday night, even once the warm front lifts through the area. With each of these short waves, there will be areas of enhanced lift and moisture. This is expected to lead to several possible periods of enhanced rainfall chances across the area, especially Monday into Monday evening. If any precipitation starts early enough Sunday night while temperatures a cold enough, a brief wintry mix may be possible for portions of northeast Pennsylvania and northern New Jersey before changing to all rain.

Then as we move into Tuesday, a cold front is expected to move across the area later during the day into the evening. This will lead to another period of enhanced rainfall chances, especially during the afternoon and evening. PW values will likely exceed 1.00 inches and approach 1.25-1.50 inches Monday-Tuesday, so there could be period of moderate to heavy rainfall at times. With the first round of rainfall Monday-Monday night, we could get around 1.00-1.25 inches, and with the second round of rainfall, we could get 0.50-0.75 inches. There is a chance for some poor drainage/nuisance type flooding in areas of heavier rainfall during Monday-Tuesday.

The cold front will have moved offshore overnight Tuesday. However, models are indicating additional short wave/vorticity impulses moving across the area behind the cold front Tuesday night into Wednesday. This could lead to another period of precipitation, but as temperatures cool behind the front, this precipitation could change over or mix with snow at times overnight Tuesday into Wednesday. There is still some uncertainty with this outcome, but if this happens, some areas could see some snow accumulations. This area of precipitation will move offshore during the first half of Wednesday, then our area will be under the influence of strong northwest flow the rest of the day. Lake effect snow showers will likely be ongoing through the day to our north across New York and northern Pennsylvania where the steepest lapse rates and enhanced moisture will be located. The low-mid level flow will likely keep the showers to our north, but there is still a slight chance if the flow turns a little more south some lake effect showers could make it down into our area later in the day.

The chance for showers cuts off by Thursday as high pressure builds across the area, so dry weather is expected for Thursday into Thursday night. This high builds offshore of New England on Friday, but dry weather continues to be expected through the day Friday, although there will be an increase in cloud cover later in the day ahead of an approaching storm system from the south.

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

Today . VFR. Northwest winds around 10 kt. High confidence.

Tonight . VFR. Light northwest winds early will turn light and variable or calm. High confidence.

OUTLOOK .

Sunday . VFR conditions expected. Southeast to south winds may gust around 15-20 knots at times. --High confidence.

Sunday night . Conditions may lower to MVFR later in the overnight ahead of a lifting warm front. South winds may shift to southeast late in the night. --Moderate confidence.

Monday-Tuesday . An extended period of MVFR and IFR conditions likely as periods of rain move across the area. Southeast winds early Monday become southwest once a warm front lifts across the area Monday. Winds shift to the northwest behind a cold front later Tuesday into Tuesday night. --Moderate confidence.

Tuesday night-Wednesday . Rain or snow remains possible with MVFR or IFR conditions possible. Improvement to VFR possible Wednesday afternoon. West to northwest winds become gusty to 20-25 knots on Wednesday.

MARINE. Update .

Have extended the Small Craft Advisory until 10AM due to lingering gusts near 25 kt with seas also having built to around 5 feet in some areas. Still expecting conditions to fall below SCA levels later this morning. Previous discussion follows.

A Small Craft Advisory remains in effect until 6:00 this morning except for the upper Delaware Bay. Currently expect this advisory will be able to come down on time but will reevaluate with the next update. Once the advisory comes down this morning, sub-SCA conditions are expected to continue through tonight. Northwest winds could gust up to 20 kt during the day today. Winds gradually shifting to northeasterly tonight. Seas 2 to 3 ft through tonight.

OUTLOOK .

Saturday-Sunday night . Conditions are expected to be below Small Craft Advisory levels.

Monday-Tuesday night . Small Craft Advisory conditions likely as winds and seas increase as a warm front lifts across the area Monday, then a cold front moves across the area Tuesday.

Wednesday . Small Craft Advisory conditions likely to continue.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 10 AM EST this morning for ANZ431- 450>455.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
