Area Forecast Discussion National Weather Service Mount Holly NJ 612 AM EST Sun Jan 26 2020

SYNOPSIS. Strengthening low pressure will move further northeast of the area today and tonight. A large area of high pressure will start to build into the region by Tuesday, and high pressure will dominate the weather for most of the work week. An area of low pressure may approach from the south by the end of the week or next weekend.

NEAR TERM /UNTIL 6 PM THIS EVENING/. We have issued an SPS for much of the area to mention the possibility of some black ice developing. The ground is wet in many areas after yesterdays rain and with the cold temperatures overnight, black ice will develop in many areas. The ice will only be around for a few hours after sunrise, when it will become too warm to support ice development.

High pressure at the surface well SW of the area will slowly build up into the Middle Atlantic today. A deep low pressure system aloft will spin up across NY and New England at the same time. These systems will yield dry weather, but cloudy at times. It's typical in these type of situations to have sunshine during the morning then more clouds for the afternoon. I can't rule out a few sprinkles or a flurry up across the higher peaks of the southern Poconos or north-most NJ, so we'll keep the slight chc pops there. Highs today will remain above normal, but 5 to 10 degrees below the abnormal warmth of the past few days. Highs will be mostly in the mid/upper 40s for most areas ,but in the low 40s for the Lehigh Valley, southern Poconos and north NJ. Winds will be gentle from the W, mostly, at 5 to 10 mph.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/. High pressure will remain in control, so a dry night is expected. Again, a brief flurry up across the far north/west is possible, so a slight chc pops will be there. Elsewhere, deceasing clouds and cool weather is expected. Lows will be mostly in the low 30s with some upper 20s across the north areas. Winds will be light.

LONG TERM /MONDAY THROUGH SATURDAY/. Overview .

A quiet work week is expected for the region as an expansive area of high pressure builds into the East out of Canada. Continuing northwest flow on Monday combined with a shortwave passage could yield a spotty rain or snow shower across the far north. Otherwise, dry weather and near seasonable temperatures will dominate the week. The only potentially more consequential weather comes towards the very end of the work week or more likely next weekend, as the flow across the CONUS becomes more amplified. There are some indications for potential storminess during that time, but it is much too early to know how that will play out.

Dailies .

Monday-Monday night . Northwesterly flow continues Monday as low pressure from over the weekend moves further away. Likely a good deal of stratocumulus again Monday especially to the north and west, with a shortwave passing near or north of the region helping to enhance this. A passing rain or snow shower is possible in the Poconos or northern NJ. Otherwise, high temperatures running above average, mainly in the low to mid 40s.

Tuesday-Thursday . Looks like a very quiet stretch of weather as high pressure builds in from the northwest. All three of these days look similar to one another as we sit in the same continental polar air mass for an extended period. Made some sizable downward adjustments to the low temperatures for the midweek period, as we will likely have multiple nights of good radiational cooling. But with dry air and 850mb temperatures a near seasonable -5 to -8C, daytime highs should be near to slightly above average. A shortwave moving through Wednesday looks to pass by with very little fanfare, and dry weather should be a lock for the entirety of this stretch.

Friday and next weekend . Most indications are for high pressure to hold through the day on Friday, with the GEM being an exception and bringing some light precip to the area. Kept the daytime Friday dry for now, and it will probably be similar to the Tuesday-Thursday period. Heading into the weekend, guidance has been fairly consistent on showing a potential storm system, but with wildly different outcomes from run to run. It is not possible at this stage to know how that storm may evolve. We can speculate that the continued lack of Arctic air in the region will lead to temperatures being marginal at best for frozen precip, especially to the east, but we have several days to let this period come into closer view.

AVIATION /11Z SUNDAY THROUGH THURSDAY/. The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today . Mainly VFR. Broken ceilings of around 4000-6000 feet can be expected for much of the day, especially this afternoon, and cannot rule out some pockets of MVFR conditions especially near ABE and RDG. Winds westerly or west-southwesterly at around 10 kt with gusts as high as 20 kt possible this afternoon. High confidence.

Tonight . VFR. Westerly or west-southwesterly wind at 5 to 10 kt. High confidence.

Outlook .

Monday-Thursday . An extended stretch of quiet, VFR conditions is expected. Westerly winds of around 10 kt on Monday with gusts to 20 kt possible during the daytime. NW winds on Tuesday with gusts up to 20 kt during the daytime hours. Light NW winds on Wednesday, and light N or NNE winds on Thursday. High confidence.

MARINE. High pressure will gradually build over the waters today and tonight. SCA flags for seas will continue today, but it doesn't appear that we will need to extend the ending time. Winds will be mostly from the W around 10 to 15 knots today with gusts near 20 knots possible. Fair weather today and tonight.

Outlook .

Monday-Thursday . An extended stretch of sub-SCA conditions is expected. Westerly winds expected Monday with gusts to 20 kt. NW winds Tuesday and Wednesday with gusts mainly below 20 kt. Light northerly or northeasterly winds should develop on Thursday. Seas 3 to 4 ft on Monday, then 2 to 3 ft for the remainder of the period.

PHI WATCHES/WARNINGS/ADVISORIES. PA . None. NJ . None. DE . None. MD . None. MARINE . Small Craft Advisory until 6 PM EST this evening for ANZ450>455.
