Fxus61 kphi 210120 afdphi area forecast discussion national weather service mount holly nj 920 pm edt Fri sep 20 2019 Synopsis High pressure will slide southward tonight and then offshore through the weekend. A cold front will approach from the west on Monday, crossing the area Monday night. High pressure will return for the midweek period. Near term until 6 am Saturday morning Temperatures dropping off fairly quickly due to radiational cooling from clear skies and light winds. Some patchy fog is possible in the predawn hours, mainly away from the urban corridor. Short term 6 am Saturday morning through Sunday Dry weather will continue through Saturday and Saturday night as high pressure remains to our south and a surface trough remains across the area. Temperatures will warm well above normal starting Saturday as ridging aloft builds across the east coast and return flow brings in warmer, more moist air. Vertical moisture remains limited, so precipitation is not expected through Saturday night, regardless of any short wave vorticity impulses. By Sunday, the ridge aloft breaks down while the high pushes offshore of the mid-atlantic coast and the weak surface trough remains near the area. This will allow for the return flow to continue through Sunday. Very warm temperatures and increasing moisture are expected through Sunday. Later Sunday, there is a chance some showers may develop to our west, but they are expected to stay out of our area and remain near the surface trough as it drifts westward through the day. Long term Sunday night through Friday Not much change in the extended period as we are largely dominated by high pressure. Main opportunity for precipitation will be with the frontal passage on Monday night. A cold front will approach the region from the west on Monday, crossing through the area Monday night. Low level moisture will be on the rise in the return flow around the departing high pressure. Flow looks to be pretty progressive with the front working through the area Monday night and then offshore by Tuesday morning. Some instability may develop head of the front with the best forcing right in front of and along the boundary. Only will mention a slight chance of thunder, mainly during the afternoon, with it waning once we head into the evening and lose the diurnal component. Once the front moves through, high pressure starts to build back into the region. There may be a weak front that moves through on Thursday but most guidance shows little moisture around and it may not be much more than a wind shift across our area.

GEOS Local Image of Mid-Atlantic    EDIT
NOTE: East coast views moved to GEOS-16. They are experimental and not well supported by NOAA so they may not be correct so be warned. This change required redoing a large amount of the GOES code. If the image you are expecting is not showing, please let me know. You may need to use the EDIT function to update your location.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
