...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE SOUTHERN MID-ATLANTIC...

...HEAVY RAIN POSSIBLE FROM THE CENTRAL GULF COAST THROUGH PARTS
OF THE TENNESSEE VALLEY AND INTO THE CENTRAL APPALACHIANS...

SCATTERED TO WIDESPREAD SHOWERS AND THUNDERSTORMS ARE DEVELOPING
ALONG A QUASI-STATIONARY FRONT EXTENDING FROM THE
MID-ATLANTIC/CENTRAL APPALACHIANS SOUTHWESTWARD TO THE LOWER
MISSISSIPPI VALLEY. THE FRONT WILL SLOWLY SAG INTO THE SOUTHERN
MID-ATLANTIC AND SOUTHEAST BY MIDWEEK. CONVECTION WILL PERSIST
ACROSS THE SOUTHEAST AND MID-ATLANTIC REGION THROUGH WEDNESDAY,
BRINGING UP TO 1.5 INCHES FOR MUCH OF THE EAST COAST. THE HIGHEST
AMOUNTS WILL LIKELY OCCUR FROM THE COASTAL NORTH CAROLINA TO THE
CHESAPEAKE BAY AND ADJACENT AREAS - WITH FORECAST TOTALS NEAR 3
INCHES.

RAIN WILL ALSO DEVELOP OVER PARTS OF THE GREAT LAKES TO THE
NORTHEAST BY TUESDAY AFTERNOON AS A COLD FRONT PUSHES SOUTHWARD
THROUGH SOUTHERN CANADA. ACCUMULATIONS WILL GENERALLY BE LESS THAN
0.50 INCH FOR THIS REGION.

UPPER-LEVEL ENERGY NEAR SOUTHERN CALIFORNIA IS SLOWLY TRACKING
EASTWARD AND IS EXPECTED TO REACH THE SOUTHERN PLAINS BY TUESDAY.
THIS ENERGY IS CAUSING SHOWERS AND A FEW EMBEDDED THUNDERSTORMS TO
FIRE UP ACROSS THE SOUTHWEST AND GREAT BASING TODAY AND IS
FORECAST TO DIMINISH BY TUESDAY MORNING.

RAIN WILL DEVELOP OVER PARTS OF THE PACIFIC NORTHWEST AND NORTHERN
CALIFORNIA ON TUESDAY AS A COLD FRONT ADVANCES THROUGH THE WESTERN
STATES AND INTO THE INTERMOUNTAIN WEST AND GREAT BASIN REGIONS BY
TUESDAY EVENING. LIGHT SNOW IS FORECAST FOR THE SIERRAS, OTHERWISE
THE PRECIPITATION IS EXPECTED TO FALL IN THE FORM OF RAIN.
