A cold front will approach from the west late tonight and Thursday. This front will combine with a developing coastal low to bring rain to the region on Thursday. Another cold front will move through on Friday. Gusty northwest winds and dry weather move in behind that front for Friday night and Saturday. Building high pressure will bring tranquil weather Saturday night and Sunday. By Monday, a cold front moving in from the north will bring a renewed shower threat. High pressure and drier weather may return for the middle of next week. Near term until 6 am Thursday morning Still quiet this afternoon as high pressure continues to slip off to the east while some high clouds are streaming in from the west. Major story will be the coastal storm that will impact the area beginning later tonight and continuing through Thursday. At this time, a piece of this system is already starting to organize off the se coast with some rain pushing north as far as virginia. And as we go through the latter part of this afternoon into this early this evening this will continue to creep north reaching the DELMARVA this evening. Otherwise, north of the mason-dixon line conditions stay rain free through this evening. As we head through the overnight tonight, shortwave energy will drop southward helping deepen an upper level trough over the eastern conus. This will result in a surface low beginning to take shape over eastern north carolina by 12z Thursday. Meanwhile, rain ahead of this system will spread north enveloping the entire CWA by morning. The one area of concern though for wintery precip will be the southern poconos where the precip is likely to begin as a bit of wet snow or a rain snow mix since low level temps will be near freezing. Any accumulation though will be a half inch or less, if that. && Short term 6 am Thursday morning through Saturday Main story will continue to be strengthening coastal low as it moves north. Forecast models continue to trend wetter with this system now indicating a good potential for 1-2+ inches of rainfall to occur over much of eastern pa into northern nj. There will be rises on the rivers but since conditions have been dry we don't think this will cause widespread hydro issues... At least on the mainstem rivers. However the smaller creeks and streams will have to be watched as some of these could overspill their banks, especially in areas that see over 1.5 inches of rain. Urban and poor drainage type flooding could also become an issue in spots though it doesn't appear rainfall rates will be enough for flash flooding. In terms of details, surface low will continue to deepen through tomorrow as it moves northward from virginia toward the DELMARVA by late day. Expect an area wide all day type rainfall event for the area with the heaviest rainfall rates looking to be over central and eastern pa and eventually northern nj. As mentioned in the near term section, precip is likely to begin as a rain snow mix over portions of the southern poconos but this should change to all rain by mid morning. Highs Thursday range from the upper 30s low 40s over the southern poconos and NW nj to the low to mid 50s over southern nj and the delmarva. Thursday night... Low pressure continues to deepen as it moves N ne right over nj then onward to southern new england. Rain will continue at least into the early evening before tapering off SW to ne as the system departs. In fact as cooler air is wrapped in behind the system the rain is likely to end as a bit of wet snow over the poconos with some minor accumulation possible. Heading into Friday, conditions should start mainly dry as the still deepening low moves northeast through new england. Winds will be gusty though as the pressure gradient increases behind the departing system. NW winds gusting at least 20 to 30 mph can be expected by the afternoon. Also during the afternoon, as the main shortwave associated with the upper level low dives S e through the area this will spark some showers returning across the area. Highs will range from around 40 over the southern poconos to the low to mid 50s over SE pa into central and southern nj. The big concern for stronger winds looks to be Friday night into Saturday as the pressure gradient tightens across the area in the wake of a secondary cold front that crosses the area Friday evening. Expecting peak gusts of at least 30 to 40 mph but have some concerns gusts of 40 to 50 mph could be realized for a time Friday night immediately following the passage of the front as cold advection aids in mix down potential. However timing with the diurnal cycle will be a mitigating factor. Cooler temperatures will be the other story with low temps Friday night generally in the 20s to low 30s and highs Saturday mainly in the 30s and 40s except around 50 over the delmarva. Combined with the wind, this will result in wind chills in the 20s and 30s so a good 10 degrees colder than the actual temps. Otherwise, other than a few lingering snow showers over the southern poconos area should be precip free under variable cloud cover. && Long term Saturday night through Wednesday The storm system will move into the canadian maritimes Saturday night and out to sea on Sunday as high pressure settles into the southeast. A southwesterly return flow on Sunday will result in max temperatures in the mid to upper 50s. Low pressure passing north of the area will drag a cold front through the region early in the new week. Showers possible Monday ending as a mix of rain snow showers on Tuesday. Fair and cool weather for Wednesday. Aviation 19z Wednesday through Monday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Rest of today... VFR conditions will continue through this evening. Winds became slightly more robust than expected, but overall a quiet day. Mid and high level clouds gradually fill in this evening. Winds |
gradually trending more southeasterly in areas where they are still southerly. Tonight... Conditions deteriorate from south to north. InitiallyVFR but ceilings lower to MVFR in the early to middle part of the night and possibly borderline ifr by late night especially near and south of phl. Rain, initially light, starts to break out around 5z. Steadier, moderate rain fills in towards the end of the night. Winds southeasterly trending towards easterly but staying on the light side, around 5 kt. Thursday... Rain, moderate to heavy at times, is likely for most of the day. Brought ceilings down to around 1000 ft, but it is possible they could be a little lower at times tomorrow morning. Winds mainly out of the east and increasing to around 10 kt, with gusts at acy up to 25 kt and around 20 kt at miv and ilg. Llws also a bit of a concern especially at southern and eastern terminals, where stronger southeasterly flow aloft is expected. Not especially confident on timing of higher winds aloft but did add llws to the acy TAF to indicate the potential. Outlook... Thursday night... MVFR ifr initially in rain and low clouds, improving to mostly MVFR later in the night near and south of phl. Winds variable at around 5 kt through midnight, then becoming NW at 5 to 10 kt. Friday... Lingering MVFR conditions early, improving to mainlyVFR but patchy areas of MVFR lingering with scattered showers developing. NW winds 10 to 20 kt with gusts to 30 kt in the afternoon. Friday night-Saturday... VFR. NW winds 15 to 20 kt with gusts to 35 kt. Saturday night-Sunday... VFR. NW winds diminish to 5 to 10 kt and gradually shift to westerly on Sunday, possibly southwesterly by Sunday afternoon. Sunday night-Monday... VFR expected Sunday night, but ceiling and visibility reductions possible by Monday with rain showers. Winds light from the west-southwest. Low confidence on Monday. Marine Conditions expected to remain below advisory levels tonight, although winds and waves begin to increase later tonight north of a developing low pressure system to our south. Thursday... East winds increase to 15-25 kt with 25-30 kt. Seas build to 4-7 ft. Vsby restrictions in rain fog. Outlook... Thursday night-Friday... Small craft advisory conditions likely with gale force winds possible late Friday. Friday night-Saturday... Nw winds 25-30 kt with 35-40 kt gusts. Winds may start to diminish Saturday afternoon and especially into the evening, possibly to SCA levels. Seas should run generally 4 to 6 ft. Saturday night-Monday... Diminishing winds with a gradual shift from northwesterly to westerly. SCA conditions should linger for the first half of Saturday night before dropping to sub-sca. Seas diminishing to 2 to 4 ft by the latter half of Saturday night and into Sunday and Monday. Tides coastal flooding Developing low pressure will move up the east coast on today and Thursday. The low will pass over new jersey Thursday night before lifting towards eastern canada. An onshore flow will develop ahead of the low from Wednesday into Thursday. Tidal departures will increase at that time. The high tide Wednesday evening should not pose any problem. It is possible that there could be some spotty minor flooding with the high tide Thursday morning. The main focus is on the Thursday evening high tide. Tidal departures of +0.8 to +0.9 feet would begin to create minor flooding at that time along the coasts of new jersey and delaware, along delaware bay and on the tidal delaware river. Departures of greater than +1.0 foot would produce some noticeable impacts on the coastal tidal communities in our region, with some roadway flooding. Also, moderate to heavy rainfall could worsen any roadway and poor drainage area flooding. Based on the present forecast, a coastal flood advisory may be needed for the Thursday evening high tide. Once the low moves away to our northeast, an offshore wind will develop and the potential for minor coastal flooding will come to an end. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... Small craft advisory from 8 am Thursday to 6 am edt Friday for anz450>455. Small craft advisory from 8 am to 6 pm edt Thursday for anz430- 431. Synopsis...
