High pressure will gradually build in from the west through Wednesday, before moving across to the north of our area on Wednesday night and Thursday. An area of low pressure will develop near the panhandle of florida late Wednesday, then track northeast along the coast of the mid atlantic Thursday into Thursday night before heading northeast into atlantic canada Friday. High pressure will then return later Friday through the weekend. Near term through Wednesday Forecast remains on track as of 9:30 pm. Light precip passing south of DELMARVA is drying up, and precip chances continue to diminish over the next couple of hours. Clouds will gradually start breaking up through the night. A few flurries could make their way into carbon and monroe but at this point expect it to generally be dry tonight. Temperatures will drop to near or below freezing across most of the cwa, but the winds and clouds will prevent a big plunge in temps, and also should limit city suburb differences. Short term Wednesday through 6 am Wednesday High pressure will be building in from the west on Wednesday with drying at all levels. Winds will remain a bit gusty as pressures continue rising but generally expecting gusts no higher than 20-25 mph. The drying should allow a decent amount of sunshine, but with strong cold advection, temps will struggle to rise much, with most of the region having their coldest day of the season thus far. Many areas will get stuck in the 30s while warmer areas should reach the lower 40s. The extremes will be the poconos, where it will likely stay near freezing, and far southern de nj, where temps may read the middle 40s. Long term Wednesday through Tuesday The first winter weather event of the season is gearing up to impact the mid-atlantic and northeast Thursday through Friday as a developing nor'easter slides along the coast. High pressure centered over the eastern great lakes Wednesday evening will build east overnight, and then parks itself over new england through the end of the work week. Unusually cold air will be in place during this time. Meanwhile, 500 mb closed low over the gulf coast will track east Wednesday night, and surface low pressure develops and begins to intensify over the southeast. The surface low will track along the coast Thursday and Thursday night, will be just south of nyc by Friday morning, then departs during the day with the 500 mb low following behind it. Overrunning precip develops out ahead of the low late Wednesday night, and some rain and or a wintry mix will move into southern portions of delmarva. Going through Thursday morning, with temperatures below freezing for for most of the region, precip starts out as snow for all but southern de and extreme southeast nj. Up to an inch of snow will fall across southern nj and delmarva, and between 1 and 2 inches of snow will fall along and south of i-78 through midday Thursday before warmer air surges northward and changes precip to all rain. A prolonged period of moderate to locally heavy rain at times will then fall through Friday. North of i-78, a prolonged period of snow will fall through the day Thursday. As the warmer air continues to lift to the north, a shallow layer of below freezing temperatures will remain in place. 850-750 mb temps will warm to +4c to +5c, and this sets the stage for a period of freezing rain across the southern poconos, the lehigh valley, and northern nj Thursday night and Friday morning. Up to 1 4" of ice is possible for the southern poconos, and up to 1 10" of ice is possible from along i-78 to i-80. Surface low pressure, followed by the 500 mb low, will then quickly track from nyc to the canadian maritimes on Friday. Precip tapers off from south to north. High pressure then builds in from the north and west for the weekend. Conditions should be dry, and highs will generally range from the upper 30s in the southern poconos, to the 40s for most of the region, to the low 50s for southern delmarva. Some upper levels disturbances may pass through the region for the start of the new work week. Will carry slight chance low chance pops for now.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
