Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. A cold front approaching from the west is expected to arrive this evening before sliding south of our region. Low pressure riding along the front should pass off the north carolina coast on Saturday. Another low pressure system may pass just south of our region on Sunday night. A complex area of low pressure approaching from the southwest is expected to affect our weather from Wednesday into Thursday.

Low pressure riding along the front should pass off the north carolina coast on Saturday. Another low pressure system may pass just south of our region on Sunday night. A complex area of low pressure approaching from the southwest is expected to affect our weather from Wednesday into Thursday. Near term until 6 pm this evening A cold front extended across western pennsylvania late this morning. The boundary will progress to the east and it should be located in the susquehanna river valley at sunset. We are anticipating a break in the cloud cover early this afternoon before another cloud deck arrives in advance of the cold front. Some light rain showers will begin to move into eastern pennsylvania from the west during the afternoon. A gusty south to southwest wind will continue to bring mild air into our region. High temperatures should range from the upper 40s in the poconos and far northern new jersey, to the upper 60s in southern delaware. Short term 6 pm this evening through 6 am Saturday The aforementioned cold front moves offshore this evening, taking whatever precipitation is left with it. Behind the front, winds will turn to the west and then northwest before becoming more to the north by early Saturday morning. Skies will remain pretty overcast tonight. With a north to northwest flow, some colder air will make its way back into the area. Overnight lows will drop down into 20s across the north to low mid 30s across the south. Long term Saturday through Thursday Overview: a series of low pressure systems riding up over a broad ridge in the caribbean could get close to our region. The first should pass south of the region Saturday into Saturday night, though DELMARVA may be on the northern fringe of the precipitation shield. The second is expected Sunday night. A third one is due to arrive mid week next week. Details: Saturday: there was another shift south with most of the operational models in the track of the low. The low should develop along the front, which by this point should be in the carolinas. Thus, it is looking even more likely that precipitation will be confined south of a wilmington to atlantic city line. Even in these locations, precipitation looks to be very light. It should be a rain snow mix for much of the event. The combination of light QPF and very low snow ratios means snow accumulations, if any, should be very light - less than an inch. Saturday night and Sunday: surface ridge noses down from the northwest, bringing dry, albeit cool, conditions for most of the period. Temperatures will likely be slightly below normal. Precipitation may begin to nudge in from the west late in the day on Sunday, but it is more likely to hold off until Sunday evening. Sunday night: although not as distinct as the mid week system (more on that below), this period also features a system that initially has two surface lows, with the southern one becoming more dominant. By the latest model trends, the southern low will likely be too far south to result in much precipitation for our region. However, light precipitation is possible with the secondary low which should be lifting from west virginia to central pa before being absorbed in the southern low. Most of the area should see snow if any precipitation does develop. However, across DELMARVA and southeastern nj, model soundings depict an elevated warm layer which could mean a narrow corridor for a wintry mix of precipitation. Monday and Tuesday: the Sunday night system moves off shore and further away from the area as a surface ridge builds south into our region. The result is cold air advection Monday into Tuesday, with temperatures by Tuesday being about 5 degrees below normal (compared to near normal on Monday). Tuesday night through Thursday: there were some significant shifts in the model solutions with the mid week system. The most notable of which is a slower trend for the onset of precipitation, and a further south track of the dominant low. |
This will probably continue to be a low confidence period, especially considering how complex the system will be. As noted by the previous shift, there will initially be two lows, one propagating from the lower mississippi valley into the great lakes region and one propagating north along the atlantic coast. Our region should be stuck in the middle of these systems Wednesday into Thursday. Precipitation could begin as early as Tuesday night, though as mentioned above, the models have trended slower with the onset of precip. As for precipitation type, that will be highly dependent on the timing of the warm front, if it even reaches our region, which will be dependent on how close the coastal low tracks to the coast. With the 00z runs, models are depicting that the warm front may not reach areas north and west of the fall line. If this trend holds, it would favor mostly snow for areas northwest of the fall line and a snow rain mix for the coastal plains. Freezing rain would be much less likely. Therefore, removed mention of freezing rain, but still mention the possibility of sleet wedensday night into Thursday morning in case the warm front does reach further northwest than currently depicted. Aviation 18z Friday through Wednesday The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg, kmiv, kacy and surrounding areas. Rest of today... MainlyVFR conditions expected. South to southwest winds 10 to 15 knots with gusts to 20 knots. Isolated showers possible late this afternoon. High confidence. Tonight... MainlyVFR conditions expected. West winds around 5 to 10 knots will turn to the northwest with gusts up to 20 knots possible overnight. High confidence. Outlook... Saturday... MostlyVFR conditions. However, there is a chance for MVFR or even ifr conditions with rain and snow at kilg, kmiv, and kacy. Northwest winds around or below 10 kts. Moderate confidence on most aspects of the forecast. However, low confidence on how far north the rain and snow will reach. Saturday night and Sunday... MostlyVFR conditions with light and variable winds. High confidence. Sunday night... A chance of snow or a rain snow mix could lower conditions to MVFR or even ifr for a period. Mostly light and variable winds. Moderate confidence. Monday through Tuesday...VFR conditions are expected. Winds should be light (generally less than 10 kt) and northwesterly or northerly. High confidence. Marine A small craft advisory is in effect for the new jersey and delaware coastal waters through tonight. A strengthening southerly flow will help to build seas across the area waters today. Seas will build to around 4 to 6 feet through today before starting to subside tonight. While we typically don't see great mixing when warm air advection occurs over the waters, we do have fairly strong winds just above the surface and it won't take much to mix them down. With this in minds, we could see winds gusts around 25 to 30 knots across the ocean waters through tonight. Winds will turn more to the west and then northwest tonight at around 10 to 15 knots. Outlook... Saturday through Tuesday... Winds and seas should stay below sca criteria, although gusts above 20 kt are possible on Monday. Phi watches warnings advisories Pa... None. Nj... None. De... None. Md... None. Marine... Small craft advisory until 4 am est Saturday for anz450>455. Synopsis... Johnson near term... Iovino short term... Meola long term... Johnson aviation...
