Winter Weather in Pennsylvania, December 7, 2007
An approaching cold front helped trigger light snow across the Poconos during the afternoon of the 7th. Accumulations averaged only one to two inches, but with temperatures below freezing, untreated roadways were slippery and slowed the afternoon commute.

Area forecast discussion, Dec 7, 9:32 AM EST, 2 hours 28 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MOUNT HOLLY NJ 932 AM EST FRI DEC 7 2007 .SYNOPSIS... HIGH PRESSURE JUST OFF THE MID ATLANTIC COAST WILL MOVE OFF TO THE EAST TODAY AS A WEAK COLD FRONT APPROACHES FROM THE WEST. ONCE THE FRONT CROSSES THE AREA SATURDAY MORNING, A WEAK AREA OF HIGH PRESSURE WILL MOVE IN FOR SATURDAY AFTERNOON INTO SATURDAY NIGHT. THEN IT APPEARS THAT OUR AREA WILL BE IN FOR A PROLONGED PERIOD OF UNSETTLED WEATHER AS HIGH PRESSURE TRIES TO PUSH IN FROM THE NORTH WHILE MILD MOIST AIR STREAMS NORTHEAST FROM THE LOWER MISSISSIPPI VALLEY. THIS PATTERN WILL PRODUCE PLENTY OF CLOUDS BUT NOT A TREMENDOUS AMOUNT OF PRECIPITATION. THE BEST CHANCE FOR A SIGNIFICANT PRECIPITATION EVENT WILL BE THURSDAY AS THE LAST IN A SERIES OF LOW PRESSURE SYSTEMS MOVES ACROSS. && .NEAR TERM /THROUGH 6 PM THIS EVENING/... AT 14Z, RADAR SHOWED THE LEADING EDGE OF THE PRECIPITATION CONTINUED TO ERODE AS IT MOVED EAST, BUT SOME MOISTENING OF THE COLUMN WAS ALLOWING PRECIP AS FAR EAST AS CENTRAL PA, THE WASHINGTON DC AREA AND THE VIRGINIA NORTHERN NECK. THE 12Z IAD SOUNDING INDICATED THAT COOLING OF THE COLUMN WAS IMMINENT IF PRECIP FELL INTO IT, AND WHEN PRECIP DID START THERE IT WAS FREEZING RAIN WITH THE INITIAL WARM LAYER ABOVE THE SURFACE AND THEN CHANGED OVER TO SNOW WITHIN AN HOUR. MEANWHILE, TEMPERATURES OVER OUR AREA WERE RISING FROM THE VERY LOW MORNING MINS, BUT THE SOUTHERN HALF OF THE FA WAS STILL IN THE MID TO UPPER 20S AS OF 14Z. A BIT OF A COOLING EFFECT SHOULD RESULT FROM WHAT SURVIVES ALOFT AS IT MOVES EAST TO US, AND SO THERE IS A BIT OF A CONCERN, GIVEN THAT INITIAL WARMER LAYER, THAT SOME OF OUR SOUTHERN LOCALES MAY SEE A LITTLE FREEZING RAIN THIS MORNING IF PRECIP CAN MAKE IT IN. THE OKX SOUNDING INDICATES ANY PRECIP THAT MAKES IT INTO THE NORTHERN ZONES THIS MORNING SHOULD MAINLY BE SNOW. FOR THIS AFTERNOON, WE STAND WITH THE POSSIBILITY OF A FEW RAIN OR SNOW SHOWERS INTO THE EVENING HOURS. && .SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/... THE WEAK SHORT WAVE THAT IS BRINGING TODAYS SHOWER THREAT WILL MOVE OFF TO THE EAST THIS EVENING. THAT WILL GIVE US A BREAK IN THE SHOWER THREAT. BUT THAT WILL BE SHORT LIVED AS THE ACTUAL FRONT APPROACHES FROM THE WEST AND BRINGS THE POSSIBILITY OF ADDITIONAL SHOWERS LATE TONIGHT INTO EARLY SATURDAY. THE FRONT WILL MOVE OFF TO THE EAST BY SATURDAY AFTERNOON BRINGING AN END TO THE SHOWER THREAT. PARTIAL CLEARING WILL OCCUR DURING THE AFTERNOON AS HIGH PRESSURE PUSHES IN BEHIND THE FRONT. THE HIGH PRESSURE WILL SETTLE OVER OUR AREA SATURDAY NIGHT GIVING US FAIR AND DRY CONDITIONS. && .LONG TERM /SUNDAY THROUGH THURSDAY NIGHT/... THE HIGH PRESSURE WILL BEGIN MOVING OFF TO THE EAST SUNDAY. THIS WILL ALLOW THE MOISTURE TRAIN FROM THE LOWER MISSISSIPPI VALLEY TO TAKE AIM ON OUR AREA. THE FIRST IN A SERIES OF LOW PRESSURE SYSTEMS WILL BRING PRECIPITATION LATE SUNDAY INTO MONDAY. THE SECOND TUESDAY INTO WEDNESDAY. AND THE THIRD, WHICH IS EXPECTED TO BE THE STRONGEST IN THE SERIES, ON THURSDAY. WITH HIGH PRESSURE PUSHING DOWN FROM THE NORTH, THERE MAY BE SOME FROZEN OR FREEZING PRECIPITATION IN OUR NORTHERN ZONES, ESPECIALLY WITH SYSTEMS 1 AND 3. IT DOES APPEAR THAT THE SYSTEM TUESDAY INTO WEDNESDAY WILL NOT HAVE MUCH, IF ANY, COLD AIR TO DRAW FROM. && .AVIATION /14Z TODAY THROUGH TUESDAY/... STILL ONLY MID CLOUDS AROUND OUR REGION AS OF 14Z. WE MAINTAIN WITH THE TAF FORECAST THAT VFR CONDITIONS WILL PREVAIL TODAY, ALTHOUGH SOME LIGHT PRECIPITATION IS POSSIBLE LATER THIS MORNING AND THIS AFTERNOON. DONT EXPECT CIGS TO DROP BELOW 3000 FT ALL DAY EXCEPT PERHAPS AROUND TAF SITE ABE THIS AFTERNOON (TO AROUND 2000 FT). LIGHT PRECIPITATION (IN MANY CASES MIXED) LATE SUNDAY INTO A GOOD PART OF NEXT WEEK WITH CIGS BELOW MVFR AT TIMES IN THE HEAVIER PRECIPITATION. && .MARINE... GENTLE LONG PERIOD SWELLS OF 2 FT EVERY 15 SECONDS AT THE BUOY THIS MORNING. IF YOU DONT MIND A LITTLE LIGHT PRECIPITATION FROM TIME TO TIME, CONDITIONS OF THE WATER WILL NOT BE THAT BAD. GENERALLY WEATHER PRESSURE PATTERS WILL NOT BUILD THE SEAS OR INCREASE THE WINDS FOR SEVERAL DAYS. SOME LIGHT FOG WILL BE THE CASE LATE WEEKEND INTO NEXT WEEK. && .PHI WATCHES/WARNINGS/ADVISORIES... PA...NONE. NJ...NONE. DE...NONE. MD...NONE. MARINE...NONE. && SYNOPSIS...RPW NEAR TERM...RPW/DELISI SHORT TERM...RPW LONG TERM...RPW AVIATION...EBERWINE/DELISI MARINE...EBERWINE

AT 815 AM, WEATHER SERVICE RADAR SHOWED AREAS OF LIGHT FREEZING RAIN AND SLEET MOVING EAST-NORTHEAST FROM THE DULLES AREA OF FAR NORTHERN VIRGINIA. THESE AREAS WERE TENDING TO DRY OUT AS THEY MOVED TOWARD SOUTHEAST PENNSYLVANIA, SOUTHERN NEW JERSEY AND THE DELMARVA, BUT WE CANNOT RULE OUT A CHANCE OF SOME LIGHT FREEZING RAIN THIS MORNING OVER NEW JERSEY NEAR AND SOUTH OF INTERSTATE 195, SOUTHEAST PENNSYLVANIA INCLUDING PHILADELPHIA AND ITS WESTERN AND SOUTHWESTERN ENVIRONS, DELAWARE AND THE MARYLAND EASTERN SHORE. IF ANY FREEZING RAIN DOES FALL, IT WOULD START AFTER 830 AM AND PROGRESS FROM WEST TO EAST. IT ONLY TAKES A SMALL AMOUNT TO MAKE ROADS SLICK AND CAUSE DETERIORATING TRAVELING CONDITIONS. IF YOU ARE DRIVING THIS MORNING OVER THE AFOREMENTIONED AREAS, PLEASE BE VERY CAREFUL. MPD
