353 AM EDT THU OCT 15 2009
VALID 12Z THU OCT 15 2009 - 00Z SAT OCT 17 2009
A DEEPENING LOW OFF THE EAST COAST HAS THE POTENTIAL TO BRING SNOW
TO THE MID-ATLANTIC REGION LATE THIS WEEK. A STRONG WAVE OF
MID-LEVEL ENERGY IS MOVING IN BEHIND THE LOW CURRENTLY OFF THE
SOUTH CAROLINA COAST. THE RAPID DEEPENING OF THIS LOW WILL ROTATE
A STRONG SURGE OF MOISTURE INLAND TO ITS NORTHWEST...PRODUCING
HEAVY PRECIPITATION ALONG THE MID-ATLANTIC COAST. COUPLED WITH THE
UNSEASONABLY COLD TEMPERATURES...THIS SYSTEM IS PRIMED TO BRING
SNOW TO CENTRAL PENNSYLVANIA...SOUTHERN NEW YORK...AND
NORTHEASTERN OHIO THROUGH SATURDAY NIGHT.
AS A RESULT OF THE STRENGTHENING COASTAL LOW...AND STRONG HIGH
PRESSURE PUSHING IN FROM THE NORTH...THE FRONT THAT HAS BEEN
CAUSING SUCH WET AND DREARY CONDITIONS ACROSS THE SOUTHEAST FOR
MORE THAN A WEEK IS FINALLY BEGINNING ITS SOUTHWARD PROGRESSION
TOWARDS THE GULF OF MEXICO. BY THIS WEEKEND THE GULF STATES WILL
FINALLY BE GETTING A MUCH NEEDED DOSE OF SUNSHINE.
A MASSIVE AREA OF HIGH PRESSURE WILL START SETTLING INTO THE NORTH
CENTRAL U.S. FRIDAY EVENING...FINALLY BREAKING UP THE STATIONARY
BOUNDARY THAT HAS BEEN DRAPED ACROSS THE CENTRAL U.S. FOR MORE
THAN A WEEK. AS THE HIGH STRENGTHENS OVER THE PLAINS AND MIDWEST
WE WILL SEE AN ADDITIONAL DROP IN TEMPERATURE ACROSS THE
REGION...KEEPING TEMPERATURES WELL BELOW NORMAL FOR THIS TIME OF
YEAR.
HEAVY PRECIPITATION ACROSS THE WEST IS FINALLY TAPERING OFF. AREAS
SOUTH OF SAN FRANCISCO CAN ANTICIPATE A SUNNY END TO THE WORK
WEEK...WHILE AREAS TO THE GOLDEN GATE CITY'S NORTH WILL REMAIN
UNDER MOSTLY CLOUDY SKIES WITH SCATTERED SHOWERS TO ROUND OUT AND
ALREADY GLOOMY WEEK. UNFORTUNATELY THERE IS TO BE NO REPRIEVE FOR
THE NORTHWESTERN U.S. AS ANOTHER PACIFIC SYSTEM TRACKS TOWARDS THE
COAST...BRINGING WITH IT THE PROMISE OF MORE RAIN FOR THIS
WEEKEND.
