(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus61 kphi 152058 afdphi area forecast discussion national weather service mount holly nj 358 pm est Sat dec 15 2018 Synopsis Low pressure will continue to move through the area through early Monday morning, before lifting off to the northeast. A cold front will pass through the region Monday, ushering in colder air. High pressure will build into the region Tuesday and Wednesday. By late week, another expansive area of low pressure looks to move toward to the area. Near term until 6 am Sunday morning Light rain continues this afternoon over the southern part of our forecast area - generally philly southward - while northern areas remain cloudy but rain free. With the upper low now over the tn valley, SW flow aloft continues bring moisture into our are, while ne winds at the surface are maintaining near steady temps and dewpts. For tonight, elongated east-west low pressure will remain to our south while high pressure to the north over new england maintains the northeast surface flow. As the upper low moves east into va, upper difluence ahead of it and a jet streak rounding the SE quad will result in stronger UVV overnight. A band of heavier precip is forecast to move generally south to north across the area from late evening through the overnight. Addition rain amounts are expected to be around a half inch or so, and no sig flood issues are likely. P-type is a concern up north however, with colder surface air filtering into the poconos and far NW nj overnight. This is expected to result in some freezing rain late tonight and Sunday, with higher elevations accumulating perhaps a tenth to a quarter inch of ice. A winter weather advisory has been issued for these areas. Short term 6 am Sunday morning through Sunday night On Sunday, the upper low will slide by just to our south while the surface low will re-organize just off the nj coast. Some areas or bands of precip will likely continue through much of the day but amounts should be less than overnight. High temps on Sunday will not be able to rise much above tonight's lows. A wintry mix may continue over higher elevations in the poconos, and may begin to spread farther south towards evening as temperatures begin to fall. Low pressure surface and aloft will move northeast and away from our area Sunday night. Precip should end from west to east and be over by dawn Monday except for some lingering snow flurries in the poconos. Long term Monday through Saturday Monday through Wednesday night... By Monday morning, the weekend coastal storm will be continuing to push offshore and out to sea. Meanwhile, high pressure will begin building across the ohio valley creating a modest pressure gradient wind across the region through Tuesday. Otherwise, the building high pressure will quickly clear things out across much of our area. A few isolated light snow showers or flurries will be possible across the poconos on Monday, however guidance has shown a faster drying trend in this activity as of the last few cycles. Winds will increase through the day Monday and persist through the overnight hours and into early Tuesday before relaxing Tuesday night as the high shifts just south of our area. Winds could potentially gust over 30 mph on Monday. Expecting Tuesday to be an exceptionally clear, but chilly day with highs only topping out in the upper 30s to low 40s. Clear and cold will remain the story Tuesday night with temps bottoming out in the low to mid 20s by Wednesday morning. Fair weather is expected to continue into Wednesday with clouds moving back into the region by later in the day. Not as cold Wednesday night with increasing cloud cover and lows around normal for this time of year. Thursday through Sunday... Pleasant weather Thursday will begin to go downhill as the next area of low pressure tracks toward our region out the gulf coast states. Unfortunately, this will likely lead to similar conditions to this current weekend in terms of widespread dreariness and rainfall. Latest guidance appears to be in good agreement with a surface low tracking up the appalachians into the eastern great lakes region, staying off to our west. This places us in the warm sector with moist southerly flow Thursday and Friday. Highs will trend 5-10 degrees average these days, ranging from near 40 in the poconos to mid 50s across southern delaware. Given the forecast strength of the system (central pressure dropping below 980 mb) and strong warm air advection, wouldn't be surprised to see these forecast highs nudge even further upwards. The amount of cloud cover will ultimately play a part too. Forecast soundings from the gfs suggest some drizzle and or mist may be possible ahead of the system on Thursday, so this may hold things in check a bit. |
The rain looks to move through the area in two waves, at least giving us somewhat of a break in between. The first round looks to move through Thursday evening through the day Friday, while the second will likely be more showery behind the cold front Saturday. Saturday will be cooler with highs approaching 50 across delmarva, while staying in the mid 30s across the northern portions of the area. Thus, some snow showers are possible across the poconos and into the higher terrain of northwest new jersey Saturday. The precipitation lifts off to the north following the surface low Saturday night. Aviation 21z Saturday through Thursday Ifr conditions remain at most of our TAF sites except for abe rdg where some drier air has filtered in at low levels. Rain is expected to re-develop and spread northward tonight, bringing a return to ifr at all sites. Northeast winds will continue through Sunday and for phl vcnty and east, they should increase and become somewhat gusty overnight into Sunday morning. Ifr conditions are expected through most of Sunday, with periods of light rain. Outlook... Monday through Monday night... MostlyVFR conditions are expected. West to northwesterly winds through may gust up to 25 kt through the evening hours. A steady breeze is expected to last through the overnight hours. Tuesday through Tuesday night...VFR conditions expected. A steady breeze is expected with northwesterly winds gusting up to 20 kt during the day. Wednesday and Wednesday night...VFR conditions expected with light west to southwesterly winds. Thursday through Sunday... MainlyVFR conditions expected. MVFR to ifr possible with snow showers across the northern portions of the area Saturday. Southerly winds through Friday 10-15 knots, turning west to northwesterly Saturday. Gusts to 25 knots are possible Friday, especially across the southern portions of the area. Marine Small craft advisories for all forecast waters and gale warnings for northern nj coastal waters remain in place. Low pressure organizing off the nj combined with high pressure over new england should produce a northeast gale starting late tonight and continuing through much of Sunday. Seas will also build up to 7 to 10 feet during this time. Vsbys will be limited in areas of rain and fog through tonight and Sunday. Outlook... Monday through Monday night... SCA conditions expected by Monday afternoon as northwesterly winds increase through the day with gale force gusts possible Monday night. Waves are expected to be in the 5-7 feet range Monday. Tuesday through Tuesday night... SCA conditions expected to last through Tuesday evening with gale force gusts possible in the morning, otherwise sub-sca conditions expected overnight. Wednesday through Wednesday night... Sub-sca expected. Thursday through Sunday... Sub-sca conditions initially will likely reaching SCA criteria Friday, lasting through Sunday morning. Winds gusting from 25-30 knots possible during this timeframe. Waves building from 8-13 feet will be possible. Phi watches warnings advisories Pa...
