NEAR TERM /THROUGH TONIGHT/
No changes to the forecast with the late morning update. 12z surface analysis shows the area of high pressure starting to slide offshore, resulting in a light northeasterly flow setting up. This will transition to more of an easterly flow as the day goes on and the high off to the northeast moves further offshore.

Otherwise, the only difference between yesterday and today looks to be some high cirrus crossing the region as a weak trough at jet-stream level moves across the area. Highs will rebound quickly with an otherwise sunny day, with highs likely nudging a degree or three above yesterday thanks to warming aloft.

Tonight, high slips further east, with a bit more southeasterly flow moistening the low levels a little bit more. Thus, will need to watch for additional areas of patchy fog and/or low clouds overnight. Lows will follow the trend of highs, nudging upward a degree or three.

SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/
High pressure will be situated to our north and east off the coast of New England through much of the short term period leading to continuing onshore flow. Aloft, a Rex Block pattern will be setting up as upper level ridging builds over the Great Lakes and closed low associated with what is currently Hurricane Francine meanders over the south-central US.

All in all, this will result in mainly clear skies throughout the period with some occasional high clouds from Francine fanning in from south to north at times. Highs will generally be in the upper 70s to mid 80s, with lows ranging from the mid 50s to low 60s. Humidity will rise some through the period but should remain rather comfortable.

LONG TERM /SATURDAY THROUGH TUESDAY/
As a whole, the long term period remains relatively unchanged through the weekend as the Rex Block pattern continues. This will yield continued dry conditions along with above normal temperatures through Sunday.

The blocking pattern does appear that it will break down early next week, which may finally result in some much needed precipitation returning to the area. For now, both the GFS/ECMWF global guidance indicate that there is potential for the development of a tropical disturbance off the Southeast US eventually lifting northward by midweek. Will have to monitor this closely as weather features following blocking patterns are often difficult to predict, but considering model to model run consistency, have maintained a 20-30% of showers on Tuesday for much of the area.

AVIATION /14Z WEDNESDAY THROUGH SUNDAY/
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG, KMIV, KACY and surrounding areas.

Today...VFR. Winds gradually veer as the day goes on. Sea-breeze looks to develop and could make it to the I-95 corridor by the late evening. Winds turn more southeasterly with the passage of the sea-breeze. Winds generally around 5 kt. High confidence in prevailing VFR, moderate confidence in wind direction and timing of wind shifts.

Tonight...VFR to start. Patchy fog then becomes possible overnight across more terminals across the area, though probably not KPHL itself. Winds southeasterly and light. Low confidence.

Outlook...

Thursday through Sunday...VFR. No significant weather expected.

MARINE
No marine headlines expected through tonight. Winds 10 kt or less and seas around 2 feet.

Outlook...

Thursday through Sunday...No marine headlines expected.
Generally easterly winds ranging between 5-15 kt. Seas around 2-3 feet through Saturday increasing up to 4 feet on Sunday.

Rip currents...

Today...Northeast winds around 5-10 mph in the morning, becoming east-southeast in the afternoon. Breaking waves around 1 to 2 feet with an 8 to 9 second period. This yields a LOW risk for dangerous rip currents for both the Jersey Shore and Delaware Beaches.

Thursday...Northeast to east winds around 5-10 mph. Breaking waves around 1 to 2 feet with a 7 to 8 second period. This yields a LOW risk for rip currents for both the Jersey Shore and Delaware Beaches.
