NWS WEATHER PREDICTION CENTER COLLEGE PARK MD

VALID 12Z MON MAY 30 2016 - 12Z WED JUN 01 2016

...LOCALLY HEAVY RAIN AND FLASH FLOODING POSSIBLE ALONG PORTIONS
OF THE EAST COAST...

...SEVERE THUNDERSTORMS AND FLASH FLOODING POSSIBLE FOR PORTIONS
OF THE CENTRAL/NORTHERN PLAINS AND UPPER MIDWEST...

...WARMING TEMPERATURES EXPECTED FOR THE WEST COAST...

TROPICAL DEPRESSION BONNIE IS FORECAST BY THE NATIONAL HURRICANE
CENTER TO CONTINUE LINGERING NEAR THE SOUTH CAROLINA COAST INTO
TUESDAY MORNING BEFORE WEAKENING INTO A POST-TROPICAL AREA OF LOW
PRESSURE. THE SYSTEM WILL CONTINUE TO SPREAD A HIGHLY MOIST AIR
MASS NORTHWARD ALONG THE U.S. EAST COAST, WHICH WILL COMBINE WITH
AN INCOMING COLD FRONT TO PRODUCE NUMEROUS SHOWERS AND
THUNDERSTORMS TODAY FROM SOUTH CAROLINA TO SOUTHERN NEW ENGLAND.
LOCALLY HEAVY RAIN AND FLASH FLOODING WILL BE POSSIBLE -- ALTHOUGH
WIDESPREAD FLASH FLOODING IS NOT EXPECTED. THE COLD FRONT WILL
MOVE OFF THE NORTHEAST AND MID-ATLANTIC COAST TUESDAY MORNING,
BRINGING AND END TO SHOWERS AND THUNDERSTORMS FOR THOSE REGIONS.
THE WEAKENED REMNANTS OF BONNIE ARE FORECAST TO LINGER OFF THE
NORTH CAROLINA COAST INTO WEDNESDAY MORNING, HOWEVER, KEEPING
SCATTERED SHOWERS AND THUNDERSTORMS IN THE PICTURE FOR THE
SOUTHEAST.

A PACIFIC COLD FRONT WILL CROSS THE NORTHERN AND CENTRAL ROCKIES
TODAY, MOVING INTO THE NORTHERN PLAINS BY AFTERNOON AS A NEW AREA
OF LOW PRESSURE DEVELOPS. SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO DEVELOP ACROSS THE CENTRAL AND
NORTHERN PLAINS THIS AFTERNOON AHEAD OF THE FRONT. THESE SHOWERS
AND THUNDERSTORMS WILL MOVE EAST INTO PORTIONS OF THE MIDWEST LATE
TONIGHT INTO EARLY TUESDAY MORNING. THE STORM PREDICTION CENTER IS
FORECASTING A SLIGHT RISK OF SEVERE THUNDERSTORMS TODAY AND
TONIGHT ACROSS PORTIONS OF THE CENTRAL AND NORTHERN PLAINS.
LOCALLY HEAVY RAIN AND FLASH FLOODING WILL ALSO BE POSSIBLE.
ADDITIONALLY, SCATTERED THUNDERSTORMS WILL BE POSSIBLE FARTHER
SOUTH ACROSS PORTIONS OF THE SOUTHERN PLAINS. TUESDAY INTO TUESDAY
NIGHT, THE COLD FRONT WILL MOVE EAST, WITH NUMEROUS SHOWERS AND
THUNDERSTORMS EXPECTED OVER A WIDE AREA FROM THE SOUTHERN PLAINS
TO THE UPPER GREAT LAKES.

HIGH PRESSURE AT THE MID AND UPPER-LEVELS OF THE ATMOSPHERE WILL
BEGIN TO BUILD ACROSS THE WESTERN U.S. OVER THE NEXT COUPLE DAYS.
THIS WILL RESULT IN DRY CONDITIONS AND WARMING TEMPERATURES.
TEMPERATURES ACROSS THE WEST COAST STATES WILL GENERALLY BE 5 TO
15 DEGREES ABOVE AVERAGE TODAY. TEMPERATURES WILL RISE ON TUESDAY,
HOWEVER, WITH AFTERNOON HIGHS EXPECTED TO BE 10 TO 20 DEGREES
ABOVE AVERAGE.
