...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE GREAT LAKES/OHIO VALLEY AND PARTS OF THE SOUTHERN PLAINS...

...HEAVY RAIN POSSIBLE OVER PARTS OF THE SOUTHERN APPALACHIANS...

A QUASI-STATIONARY FRONT EXTENDING FROM THE GREAT LAKES TO THE
SOUTHERN PLAINS WILL SLOWLY BEGIN TO DISSIPATE OVER THE PLAINS AND
MISSISSIPPI VALLEY BY WEDNESDAY EVENING.  A PLUME OF MOISTURE FROM
THE GULF OF MEXICO EXTENDING FROM THE CENTRAL GULF COAST TO THE
OHIO VALLEY WILL MOVE EASTWARD TO THE EAST COAST LATE TUESDAY INTO
WEDNESDAY.  THE MOISTURE WILL AID IN PRODUCING SHOWERS AND
THUNDERSTORMS FROM THE CENTRAL GULF COAST TO THE UPPER GREAT LAKES
THAT WILL SLOWLY MOVE TO THE EAST COAST BY WEDNESDAY.  ADDITIONAL
SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER PARTS OF THE SOUTHERN
PLAINS AND ALONG THE DISSIPATING FRONT OVER PARTS OF THE
MIDDLE/LOWER MISSISSIPPI VALLEY TUESDAY EVENING INTO WEDNESDAY
EVENING.  IN ADDITION, RAIN WILL DEVELOP OVER PARTS OF THE UPPER
GREAT LAKES ON TUESDAY NIGHT INTO WEDNESDAY MORNING.

MEANWHILE, UPPER-LEVEL ENERGY OVER THE ROCKIES WILL AID IN
PRODUCING SHOWERS AND THUNDERSTORMS OVER PARTS OF THE
NORTHERN/CENTRAL ROCKIES AND PARTS OF THE GREAT BASIN THROUGH
WEDNESDAY.  ON WEDNESDAY SOME OF THE ENERGY WILL MOVE EASTWARD TO
THE NORTHERN PLAINS.  THE ENERGY WILL TRIGGER SHOWERS AND
THUNDERSTORMS OVER PARTS OF THE NORTHERN/CENTRAL PLAINS WEDNESDAY
AFTERNOON INTO EVENING.

VALID 00Z TUE MAY 26 2015 - 00Z THU MAY 28 2015

***STORMY WEATHER AND FLOODING OVER THE SOUTHERN PLAINS***

***SCATTERED SHOWERS AND THUNDERSTORMS OVER THE WESTERN U.S.***

***WARM AND HUMID ACROSS MUCH OF THE EASTERN U.S.***

ANOTHER ROUND OF BAD WEATHER IS AFFECTING CENTRAL AND EASTERN
TEXAS, AND EASTERN OKLAHOMA MONDAY EVENING AS ANOTHER SURGE OF
MOISTURE FROM THE GULF OF MEXICO INTERACTS WITH A POTENT SHORTWAVE
ALOFT.  HEAVY RAIN WILL ONCE AGAIN BE A CONCERN OVER AREAS THAT
RECEIVED EXCESSIVE RAINFALL OVER THE WEEKEND, AND THIS COULD LEAD
TO FLASH FLOODING ISSUES.  SEVERE THUNDERSTORMS ARE ALSO EXPECTED
FROM TEXAS TO THE MIDWEST STATES AS THIS DISTURBANCE LIFTS TO THE
NORTHEAST ON TUESDAY ACROSS THE MISSISSIPPI RIVER VALLEY AND
TOWARDS THE GREAT LAKES REGION.  AN ADDITIONAL AREA OF HEAVY RAIN
AND STORMS IS LIKELY ACROSS THE DEEP SOUTH.

OVER THE WESTERN THIRD OF THE U.S., MAINLY DIURNALLY DRIVEN
SHOWERS AND THUNDERSTORMS CAN BE EXPECTED EACH AFTERNOON AND
EVENING FROM THE SIERRA NEVADA MOUNTAINS TO THE FRONT RANGE OF THE
ROCKY MOUNTAINS.  INSTABILITY FROM A BROAD UPPER LEVEL TROUGH OVER
THE REGION WILL PROMOTE THE DEVELOPMENT OF THIS CONVECTION, AND
THE GREATEST COVERAGE IS EXPECTED FROM UTAH TO WESTERN MONTANA.

THE BERMUDA HIGH OFF THE EAST COAST IS ALLOWING FOR BUILDING HEAT
AND HUMIDITY ACROSS MUCH OF THE EASTERN U.S. THIS WEEK.  SUSTAINED
SOUTHERLY FLOW AND RIDGING ALOFT WILL RESULT IN WIDESPREAD HIGHS
IN THE 80S TO LOWER 90S ALONG WITH DEWPOINTS WELL INTO THE 60S TO
AROUND 70 DEGREES, WHICH IS MORE TYPICAL OF LATE JUNE.  RAIN
CHANCES RETURN BY TUESDAY AND WEDNESDAY AS THE DISTURBANCE
CURRENTLY TO THE WEST BEGINS AFFECTING THE REGION.  HOWEVER, THE
STRENGTH AND SEVERITY WILL BE SIGNIFICANTLY LESS THAN WHAT IS
HAPPENING OVER THE PLAINS GIVEN THE STRONG RIDGE OFF THE COAST.
