PHL Terminal Aviation Weather Discussion (AFD) - Prepared: 338 PM EDT SAT SEP 20 2014


.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG, 
KMIV, KACY AND SURROUNDING AREAS.

VFR CONDITIONS ARE ACROSS THE TERMINALS FOR THE MOST PART THIS 
AFTERNOON. WHEN THE DIURNAL CU KICKED IN...A FEW SHORT PERIODS OF 
MVFR WERE OBSERVED...AND THIS COULD STILL HAPPEN AGAIN EARLY...BUT 
FOR THE MOST PART VFR SHOULD CONTINUE INTO THE EVENING. A FEW WIDELY 
SCT SHOWERS MAY DEVELOP ACROSS THE DELMARVA OR SE NJ LATER...BUT 
THEY WERE NOT PUT IN THE TAFS WITH CONFIDENCE IN THIS RATHER LOW. 

TONIGHT...THE CONTINUING ONSHORE FLOW WILL CONTINUE AND WITH A BLEND 
OF THE PREVIOUS TAFS AND THE PRESENT GUIDANCE...WE HAVE FAVORED A 
SLOW LOWERING OF CIGS AND VSBYS IN FOG OVERNIGHT. SOME LIGHT SHOWERS 
OR PATCHY DRIZZLE MAY OCCUR CLOSE TO THE SHORE. THIS WAS PLACED IN A 
TEMPO GROUP FOR KACY. SUNDAY...SLOW RECOVERY BACK TO VFR WITH AN 
APPROACHING COLD FRONT AND A GRADUAL SWITCH IN WINDS TO SW. IT IS 
LIKELY THAT MOST SITES WILL BE BACK TO VFR 14Z-16Z. 

OUTLOOK...

SUNDAY NIGHT...COLD FRONT MOVES THRU THE TERMINALS. SCT SHRA ALONG 
AND AHEAD OF THE FRONT BUT GENERALLY VFR CONDITIONS EXPECTED. WIND 
SHIFT FROM SW TO NW WILL OCCUR WITH THE FROPA. 

MONDAY...NW WIND GUSTS AROUND 20 KT ARE POSSIBLE MONDAY IN 
ASSOCIATION WITH POST-FRONTAL PRESSURE SURGE. STRATOCU FAVORED IN 
THIS SETUP, WHICH MAY RESULT IN A PERIOD MVFR CIGS FOR PHILLY 
TERMINALS NORTH AND WEST.

MONDAY NIGHT THROUGH THURSDAY...VFR AND LIGHT WINDS EXPECTED.
