VALID 00Z THU FEB 14 2013 - 00Z SAT FEB 16 2013

...LIGHT SNOW EXPECTED FOR PARTS OF MID ATLANTIC/SOUTHERN NEW
ENGLAND WEDNESDAY NIGHT...

...LIGHT SNOW SHOWERS ARE EXPECTED FROM THE DAKOTAS TO THE GREAT
LAKES...

...RAIN EXPECTED FOR FLORIDA THROUGH THE END OF THE WORK WEEK...

A SURFACE LOW PUSHING THROUGH THE MID ATLANTIC TODAY WILL
INTENSIFY OFF THE DELAWARE COAST THIS EVENING. A BAND OF LIGHT
SNOW WILL DEVELOP ALONG THE NORTHERN EDGE OF THE PRECIPITATION
SHIELD. A SWATH OF LIGHT SNOW WILL AFFECT SOUTHEASTERN
PENNSYLVANIA THROUGH LONG ISLAND AND EXTREME SOUTHERN NEW ENGLAND.

A SURFACE LOW DIVING SOUTHEASTWARD OUT OF CANADA WILL BRING LIGHT
SNOW FROM THE DAKOTAS INTO THE GREAT LAKES THROUGH FRIDAY. DUE TO
A LACK OF MOISTURE...PRECIPITATION SHOULD REMAIN ON THE LIGHTER
SIDE FOR THE NORTHERN PLAINS AND UPPER MIDWEST. ONCE THE SURFACE
LOW PASSES THE GREAT LAKES...LAKE EFFECT SNOW IS EXPECTED TO
DEVELOP DOWN WIND OF EACH GREAT LAKE...AND THE INCREASED MOISTURE
FROM THE LAKES COULD INCREASE PRECIPITATION INTENSITY.

IN THE WEST... A BUILDING UPPER LEVEL RIDGE WILL MOVE INLAND BY
THE END OF THE PERIOD. UNTIL THEN...HEAVY PRECIPITATION ALONG THE
WEST COAST WILL REMAIN IN BRITISH COLUMBIA...BUT ONSHORE FLOW IS
EXPECTED TO BRING LIGHT PRECIPITATION TO WASHINGTON. AS THE RIDGE
BUILDS OVER THE WEST...AN UPPER LEVEL JET WILL DIVE SOUTHWARD OVER
THE ROCKIES...BRINGING LIGHT SNOW SHOWERS TO MUCH OF THE HIGHER
ELEVATIONS.

IN FLORIDA...A FRONTAL BOUNDARY WILL STALL OUT OVER THE SOUTHERN
PORTION OF THE STATE. SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED THROUGH THURSDAY. BY THURSDAY EVENING...AN APPROACHING
SHORTWAVE IS EXPECTED TO ENHANCE PRECIPITATION INTENSITY AND
COVERAGE...RESULTING IN HEAVY RAINFALL ACROSS CENTRAL AND SOUTHERN
FLORIDA.
