High pressure builds back in from the north and west on Tuesday, then moves into gulf of maine Tuesday night. A complex area of low pressure will move through the northeast Wednesday through Thursday. High pressure builds in from the north and west to close out the week. Low pressure impacts the area next weekend. Near term until 6 am Monday morning Update... precip has overspread much of the area as of 9:30 pm. Temperatures remain in the low to mid 30s across a large portion of the area, with the exceptions being NW nj, the poconos, and portions of the lehigh valley. The big concern this evening continues to center over precip type. The general trend is for mixed precip to occur over the lehigh valley and into the poconos NW nj, but exactly what for occurs where remains tricky. Based on current surface temperatures, am beginning to think that more areas are going to stay mostly rain. Do anticipate surface temperatures to cool both diurnally and due to evaporative effects. This should drop temperatures near to just below freezing across the lehigh valley. This will make all the difference as to whether surfaces stay wet or begin to freeze. However, freezing rain has been reported across parts of maryland, mostly between baltimore and the mason dixon line, so this could be an indication that surfaces will continue to cool as the remaining boundary layer continues to moisten. Since temperatures will sit right on the freezing line, it's looking more likely that freezing rain issues will be more localized. This could still cause issues as roadways may freeze in some area, while only remaining wet in others. Adjusted the grids to reflect this. All in all, precip type is a bit of a beast with this system. Previous discussion... the latest winter storm will be affecting our region mostly during the near term with low pressure moving towards WRN pa as another low forms off the DELMARVA coast overnight. Between these lows, there is plenty of moisture and temperatures are marginal for either all rain or snow. Complicating things is the temperates aloft which are not strongly indicating any preferred p-type. We will mostly keep things as they are, but also add chester and northern montgomery county into the present winter weather advisory. It's possible that these areas may also get some light -zr this evening. Confidence in p-type along the edges of the advisory is not the best, so it's good that the overall amounts will not be too high and that the timing of the system is not during any exceedingly busy commuting period. The precipitation will arrive from SW to NE this evening and be mostly rain across DELMARVA and SRN nj. A little sleet at onset wounln't be surprising however. Across the delaware valley a mix of sleet and rain is expected with a change to rain overnight. The lehigh valley area will have some snow and sleet and then some freezing rain overnight. The northern most areas will have sleet and freezing rain with some snow possible. The precipitation will end from W to E around dawn. Lows tonight will drop into the mid upper 20s across the north and remain in the low mid 30s across much of the rest of the area. Winds will be mostly light from the SE or e, becoming w towards dawn. Short term 6 am Monday morning through 6 pm Monday On Monday, the low pressure system, associated with the bad weather Sunday night, will be offshore and moving away from our region. Improving conditions will arrive during the morning with the precipitation done (for ERN areas) by mid-morning. A drier and gusty west wind will develop across the area with increasing amounts of sunshine expected by afternoon. High temperatures will be in the upper 40s low 50s S E and in the upper 30s to mid 40s across the southern poconos lehigh valley and NRN nj. Wind gusts up to 30 mph expected to develop during the afternoon. Long term Monday night through Sunday High pressure over the northern plains states Monday evening will slowly build to the south and east early in the new week, and will be centered over new york state by Tuesday evening. Meanwhile, a deep upper trough with several strong shortwaves will move out of the rocky mountains and into the plains. Surface low pressure will develop out ahead of that trough over the gulf coast states, and will lift through the lower mississippi valley and towards the tennessee valley by Wednesday morning. The 1040 mb high over ny will slowly push east, and overrunning precip will develop out ahead of the developing low and lift into DELMARVA and the delaware valley by Wednesday morning. 12z guidance seems to have slowed the onset of precip, with precip not really making it into the southern and far western portions of the area until closer to daybreak Wednesday, and then precip will overspread the area from southwest to northeast by midday Wednesday. Low pressure redevelops over the mid-atlantic late Wednesday, and passes over nj Wednesday night before moving out to sea on Thursday. Ptype issues will be abundant with this system. Precip starts out as accumulating snow late Tuesday night through Wednesday morning. As the afternoon progresses, the high moves towards cape cod, allowing winds to shift to more of an easterly flow, then more of a southeast flow. Although there should be good cad initially, the position of this high allows for some warmer air at both the surface and in the midlevels to lift in from the south. Snow becomes a wintry mix for southern new jersey, the delaware valley, including philly, and DELMARVA early Wednesday afternoon, but snow continues for northern nj, the lehigh valley, and the southern poconos through at least the daytime hours Wednesday. Going through Wednesday evening, precip changes to plain rain for delmarva, while precip becomes rain and sleet for much of southern nj and southeast pa, eventually becoming plain rain. For the northern half of the forecast area, as well as far western zones, expecting a prolonged period of sleet and |
freezing rain that will result in accumulating ice Wednesday night. Will continue to monitor potential for at least winter weather advisories with this system. By Thursday morning, precip eventually becomes all rain before tapering off behind the departing low. High pressure then builds back in from the north and west. A frontal boundary seems to set up across the mid-atlantic, and several waves of low pressure will pass along this boundary, likely staying south of the region through the end of the work week. The high moves overhead on Friday, then offshore for the weekend. Another storm system may lift in from the south and west next weekend. Aviation 03z Monday through Friday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. This afternoon... Increasing clouds. Light E to SE winds. Tonight... Lowering CIGS and then vsbys with precipitation arriving 00 01z (west) and 02z 03z (east). P-type: rain expected at kmiv kacy with mostly snow sleet freezing rain at kabe krdg. The delaware valley will have mostly a mix of snow sleet initially, then a change to rain overnight. Ifr CIGS expected shortly after precip arrives and will remain through the night. Winds E to SE at 5 to 10 knots. Monday... The precipitation will be ending across the eastern areas during the morning and improving CIGS and vsbys will continue. Any ifr MVFR conditions will improve toVFR during the morning as drier air arrives on a moderate west wind.VFR will likely return to the delaware valley (and phl) around 13z 14z time frame. TheVFR will remain for the rest of the day once it arrives. Wind speeds will increase during the afternoon with some g25 expected. Outlook... Monday night through Tuesday...VFR. NW winds 10 kt or less. High confidence. Tuesday night through Wednesday night...VFR will become MVFR late Tuesday night and then become MVFR ifr as snow, rain, and a wintry mix move through the terminals. Northeast to east winds around 10 knots or less. Low confidence with respect to precipitation type. Thursday... MVFR or lower conditions in the morning, improving toVFR late in the day. West to northwest winds around 10 knots. Moderate confidence. Friday...VFR. N winds 5-10 kt. Marine Tonight... Sub-sca conditions with E to SE winds around 10-12 knots. Rain developing with snow possible across the northern waters. Monday... Sub-sca early then increasing west northwest winds and building seas with SCA flag for the afternoon. Rains ending during the morning then fair. Outlook... Monday night through Tuesday... SCA continues through Monday night before diminishing by early Tuesday morning. Seas generally around 2 to 4 feet, subsiding some through the night. Wednesday through Wednesday night... East winds increasing to 15-20 kt. Vsby restrictions in snow, then a wintry mix, then rain by Wednesday night. Seas possibly building to SCA levels Wednesday night. Thursday... Potential for SCA level seas on the ocean waters. Otherwise, sub-sca conditions. Friday... Sub-sca conditions. Tides coastal flooding A subtle onshore flow will continue through much of the night. Tidal departures around this morning's high tide were generally in the +0.7 to +0.9 foot range, a bit higher than originally anticipated. The onshore flow and the decreasing atmospheric pressure should cause those departures to increase by a few tenths of a foot by Monday morning's high tide. We are now anticipating some advisory level minor flooding in coastal areas of new jersey and delaware on Monday morning. We have issued a coastal flood advisory that is in effect from 5:00 am until 11:00 am. It appears as though at least some spotty minor flooding may occur with the morning high tides into the mid week period. We will continue to monitor the water level trends. The full moon occurs on Tuesday. Phi watches warnings advisories Pa... Winter weather advisory until 10 am est Monday for paz054-055- 060>062-101>103-105. Nj...
