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

...HEAVY RAIN POSSIBLE OVER PARTS OF THE NORTHERN MID-ATLANTIC
INTO THE GREAT LAKES...

A DEEP UPPER-LEVEL LOW OVER THE OHIO VALLEY WILL SINK SOUTHWARD
INTO THE SOUTHERN OHIO VALLEY/TENNESSEE VALLEY BY FRIDAY.
CIRCULATION AROUND THE UPPER-LEVEL LOW WILL STREAM MOISTURE OFF
THE ATLANTIC INTO THE MID-ATLANTIC/GREAT LAKES AND THE OHIO
VALLEY.  SHOWERS AND THUNDERSTORMS WILL DEVELOP ALONG AND NEAR THE
ASSOCIATED FRONT FROM PARTS OF THE GREAT LAKES/OHIO VALLEY TO THE
MID-ATLANTIC AND THE SOUTHEAST THROUGH FRIDAY.  RAIN ASSOCIATED
WITH THE SHOWERS AND THUNDERSTORM WILL BE HEAVY AT TIMES OVER
PARTS OF THE NORTHERN MID-ATLANTIC/CENTRAL APPALACHIANS AND THE
LOWER GREAT LAKES WANING BY FRIDAY MORNING.

MEANWHILE, MONSOONAL MOISTURE AND DAYTIME HEATING WILL AID IN
PRODUCING SHOWER AND THUNDERSTORMS OVER THE SOUTHWEST/GREAT BASIN
AND THE CENTRAL/SOUTHERN ROCKIES THROUGH FRIDAY.  IN ADDITION,
UPPER-LEVEL TROUGHING AND UPPER-LEVEL ENERGY MOVING ACROSS THE
NORTHWEST INTO THE NORTHERN HIGH PLAINS WILL AID IN PRODUCING
SHOWERS AND THUNDERSTORMS OVER PARTS OF THE NORTHERN
ROCKIES/NORTHERN INTERMOUNTAIN REGION THURSDAY MORNING INTO
FRIDAY.
