HIGH PRESSURE OVER THE BASIN IS MOVING SLOWLY TO THE NORTH AND EAST
TODAY AS A LOW PRESSURE SYSTEM IS CENTERED OFF THE CAROLINA COAST.
THIS LOW WILL MOVE ALONG THE EAST COAST TODAY AND TOMORROW. LOW
PRESSURE OVER THE NORTHERN PLAINS WILL MOVE INTO THE NORTHERN GREAT
LAKES BY WEDNESDAY AFTERNOON.

A DEVELOPING LOW PRESSURE SYSTEM WILL STRENGTHEN ALONG THE GULF COAST
TOMORROW AND WILL MOVE NORTHEAST INTO THE TENNESSEE VALLEY BY WEDNESDAY
MORNING. PRECIPITATION AHEAD OF THIS SYSTEM WILL MOVE INTO OUR SOUTHERN
BASIN DURING THE EARLY MORNING HOURS OF WEDNESDAY. THIS SYSTEM WILL
EVENTUALLY MOVE NORTH OF THE GREAT LAKES AND WILL SWING A STRONG COLD
FRONT THROUGH THE BASIN.

PRECIPITATION AMOUNTS FOR THE NEXT 3 DAYS RANGE FROM ABOUT A HALF INCH
IN THE FAR WESTERN BASIN (CENTRAL/WESTERN PENNSYLVANIA...WESTERN
MARYLAND...AND WESTERN VIRGINIA) TO OVER AN INCH IN THE FAR EASTERN
PORTION OF THE BASIN (EASTERN PENNSYLVANIA...NEW JERSEY...AND EASTERN
VIRGINIA). THIS PRECIPITATION IS FORECAST TO PRODUCE MINOR RISES OF ONE
TO FOUR FEET ON MANY OF OUR RIVERS...HOWEVER NO FORECAST POINTS ARE
EXPECTED TO EXCEED FLOOD STAGE.
