SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
423 AM EDT WED JUN 03 2015

VALID 12Z WED JUN 03 2015 - 12Z FRI JUN 05 2015

...STORMS TO CONTINUE ACROSS THE NORTHERN AND CENTRAL PLAINS...

...SHOWERS AND THUNDERSTORMS EXPECTED THROUGHOUT THE MID-ATLANTIC
AND SOUTHEAST...

...UNSETTLED WEATHER ANTICIPATED FOR THE PACIFIC NORTHWEST AND
NORTHERN ROCKIES...


CURRENTLY, AN ORGANIZED BAND OF THUNDERSTORMS IS PROGRESSING
EASTWARD ACROSS THE CENTRAL PLAINS TOWARDS THE MIDDLE MISSISSIPPI
VALLEY.  THIS TREND WILL CONTINUE OVER THE NEXT FEW DAYS AS
DISTURBANCES MOVE AHEAD OF THE UPPER LEVEL TROUGH SLIDING ACROSS
THE WEST COAST WITH CONVECTION BEING TRIGGERED AND PROGRESSES
EASTWARD ACROSS THE PLAINS AND MISSISSIPPI VALLEY.  FOR WEDNESDAY,
THE STORM PREDICTION CENTER HAS AN ENHANCED RISK OF SEVERE STORMS
FOR PARTS OF THE CENTRAL PLAINS ACCOUNTING FOR ANOTHER ROUND OF
CONVECTION.  HOWEVER, IN GENERAL, SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED FROM THE CENTRAL AND NORTHERN PLAINS EASTWARD INTO THE
UPPER GREAT LAKES THROUGH THURSDAY MORNING. AS THE COLD FRONT
PUSHES SOUTHEASTWARD BY THURSDAY AFTERNOON TOWARD THE MISSISSIPPI
VALLEY AND SOUTHERN PLAINS, THE AXIS OF CONVECTION WILL FOLLOW
SUIT AND STAYS AHEAD OF THE FRONT.

ANOTHER UPPER LEVEL LOW HAS BEEN SLOWLY MOVING EASTWARD OVER THE
SOUTHEAST.  AT THE SURFACE, A STATIONARY FRONT HAS BEEN DRAPED
ACROSS THE SOUTHEAST AND DEEP SOUTH.  WITH PLENTY OF MOISTURE ON
TAP, AND THE STATIONARY FRONT PROVIDING A FOCAL POINT, SHOWERS AND
THUNDERSTORMS WILL CONTINUE THROUGHOUT THE MID-ATLANTIC AND
SOUTHEAST.  THE HEAVIEST RAINFALL ACTIVITY WILL BE CONFINED TO THE
COAST OF THE CAROLINAS AND GEORGIA.  THIS STATIONARY FRONT STAYS
PUT THROUGH THURSDAY EVENING.  THUS, EXPECT SHOWERS AND
THUNDERSTORMS TO LINGER THROUGH THAT TIME FRAME.  FARTHER SOUTH,
FLORIDA WILL RECEIVE ITS USUAL DIURNALLY-DRIVEN THUNDERSTORM
ACTIVITY THROUGHOUT THE SHORT TERM PERIOD.

AS THE UPPER LEVEL LOW ON THE WEST COAST DEEPENS AND DIGS
SOUTHWARD ACROSS THE WEST COAST, SHOWERS AND THUNDERSTORMS WILL
INCREASE IN COVERAGE.  SHOWERS WILL BE FOCUSED IN THE PACIFIC
NORTHWEST THROUGH WEDNESDAY EVENING.  BY THURSDAY, THE FOCUS
SHIFTS EASTWARD ACROSS THE NORTHERN ROCKIES AND INTERMOUNTAIN
WEST.
