Fxus61 kphi 191315 afdphi area forecast discussion national weather service mount holly nj 915 am edt Sat oct 19 2019 Synopsis High pressure will build to our east later today and tonight. Low pressure tracks from the eastern carolinas later tonight to offshore of the mid-atlantic coast during Sunday, then it moves out to sea into Monday. A cold front moves through our region late Tuesday, followed by high pressure Wednesday and Thursday. The next cold front should arrive later Friday. Near term until 6 pm this evening Temperatures will continue to slowly increase through the morning. Therefore, the frost advisory and freeze warning were allowed to expire at 9 am. Minimum temperatures early this morning dropped to 32 degrees or lower for the majority of both sussex and warren counties in new jersey, thus, the growing season has ended. This terminates the autumn frost freeze program for these two counties. Frost advisories or freeze warnings will no longer be issued for both sussex and warren counties for the remainder of 2019. Otherwise, no significant changes to the forecast with this update. High pressure centered over central pennsylvania will pass over new jersey today, and then offshore by the end of the period. Abundant sunshine on tap for the day. Return flow sets up this afternoon, and temperatures warm up a bit compared to Friday. Highs top off in the upper 50s in the southern poconos, and otherwise in the low to mid 60s. Short term 6 pm this evening through 6 am Sunday High pressure continues to drift offshore tonight. Meanwhile, tropical storm nester will be over the southeast u.S. This evening, and will lift towards the carolina coast during the overnight hours. The significant impacts will remain well to the south of the forecast area, but rain will begin to lift into southeast maryland and delaware towards daybreak Sunday. With increasing clouds and waa, lows tonight will be warmer, in the low to mid 50s for most of the region, and around 50 in delmarva. Long term Sunday through Friday Summary... Rain associated with current tropical storm nestor moves across much of our area Sunday before ending Sunday night. A cold front moves through later Tuesday with another cold front arriving later Friday. Synoptic setup... Amplified flow aloft with a trough ejecting into the plains with another trough from the great lakes to the mid- atlantic Sunday, then ridging builds across the east into early next week as a significant trough digs across the plains. This trough shifts eastward through midweek before lifting into canada with some zonal flow in its wake across the northern tier. Another trough amplifies into the northern plains late Wednesday, which then shifts eastward through Friday. For Sunday... Low pressure (remnants of current tropical storm nestor) is expected to move northeastward across the eastern carolinas, exiting off the coast near CAPE hatteras during Sunday. The low is then forecast to move out to sea during early next week. Despite the trough aloft weakening some as it slides across our region Sunday, the track of the surface low and ascent to its north and northwest side will result in a shield of rain. The highest rainfall amounts are expected to be across southeastern new jersey and into southern delaware. However, much of the guidance brings measurable rain to much of region. Based on this and the latest qpf forecast from wpc, increased the pops north and westward during the day Sunday. There will be a period of gusty onshore winds mainly along the coast Sunday into Sunday night, and while there is some uncertainty with the magnitude some guidance suggests 40-ish mph gusts. As of now though, we kept the winds well below advisory criteria. The conditions should quickly improve during Sunday night from west to east as the system moves far enough away and the flow turns more from the north, allowing some drying to work in. Temperatures were lowered Sunday across much of the area given onshore flow along with clouds and rain. For Monday... A sliver of surface high pressure extends southward across our area. Any lingering breeze along the coast is expected to subside as the pressure gradient collapses due to high pressure building in. The return of some sunshine should result in milder afternoon temperatures. For Tuesday... A strong area of low pressure is expected to lift from the upper mississippi valley and the western great lakes Monday and into western ontario during Tuesday. This feature is anticipated to pull a cold front through our region late Tuesday. The amplification of the parent upper-level trough should result in a slower arrival

of the cold front. We continue to mention a chance of showers ahead of and with the front, however given uncertainty regarding available instability held off in adding a thunder mention. For Wednesday and Thursday... High pressure is forecast to build across the southern states Wednesday, then across our region and off the coast Thursday. This should have enough of an influence on our weather and therefore we anticipate dry conditions. For Friday... The next cold front arrives later during this time frame, although timing is somewhat uncertain. Given the synoptic setup that is forecast, there is the potential for a surface low to develop along the front as it is crossing our area. If this were to occur, the precipitation would be enhanced across our region. For now and based on wpc guidance with the front arriving late, kept some slight chance pops in the gridded forecast. Aviation 13z Saturday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Today...VFR skc. Lgt vrb winds this morning, becoming SW less than 10 kt this afternoon. High confidence. Tonight...VFR. SW winds less than 10 kt become lgt vrb after 00z. High confidence. Outlook... Sunday... MVFR ifr conditions probable, especially for phl pne, ilg, ttn, miv and acy, due to rain and low ceilings. Conditions should improve toVFR during the night.

Moderate confidence regarding a period of MVFR or lower conditions, but low confidence on the timing and also wind speeds. Monday...VFR into the evening, then conditions may lower to MVFR or ifr during the night with some possible showers especially at abe and rdg. Northeast to east winds 5-10 knots, becoming southeast at night. High confidence during the day; low confidence at night. Tuesday... MVFR ifr conditions spread across the region through the day with showers, then conditions should quickly improve toVFR during the night. Moderate to high confidence on conditions below vfr, but low confidence on the timing of flight category changes. Southeast to south winds around 10 knots, shifting to northwesterly at night. Wednesday... MostlyVFR. Westerly winds of 5-15 knots. Moderate confidence. Marine Sub-small craft advisory conditions on tap for today and tonight. Nw winds around 15 kt with gusts up to 20 kt, become around 10 kt this morning, then become light and variable this afternoon. Winds tonight become s-se around 10 kt. Seas 2 to 3 ft. Outlook...

While wind gusts should drop below 25 knots, seas on our ocean waters are forecast to remain elevated. Tuesday... The conditions should be mostly below small craft advisory criteria during the day, however a wind shift to northwesterly behind a cold front at night may result in a wind surge with gusts to around 25 knots. Wednesday... West or west-northwest wind gusts to around 25 knots probable before diminishing at night. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine...
