...HEAVY RAIN, SEVERE THUNDERSTORMS AND FLASH FLOODING POSSIBLE
FROM PORTIONS OF THE SOUTHERN PLAINS EASTWARD ACROSS THE TENNESSEE
VALLEY TO THE MID ATLANTIC STATES...

...TEMPERATURES ACROSS THE NORTHWESTERN U.S. WILL REMAIN WELL
ABOVE AVERAGE...

...MUCH COOLER TEMPERATURES BEGIN TO MOVE INTO THE NORTHERN
ROCKIES BY SUNDAY...

THE WEATHER PATTERN FOR THE NEXT SEVERAL DAYS WILL BE ON AUTO
PILOT WITH A CONTINUATION OF HEAVY SHOWERS, THUNDERSTORMS AND THE
POSSIBILITY OF SEVERE WEATHER ALONG A NEARLY STATIONARY FRONTAL
BOUNDARY EXTENDING FROM THE SOUTHERN PLAINS EASTWARD TO THE EAST
COAST.  THE FRONT SEPARATES RELATIVELY COMFORTABLE CONDITIONS
ACROSS THE MIDWEST, GREAT LAKES AND NORTHEAST FROM VERY WARM HUMID
CONDITIONS ALONG THE GULF COAST AND SOUTHEAST AND WILL CONTINUE TO
FOCUS THE CHANCES FOR HEAVY PRECIPITATION FROM SOUTHERN KANSAS AND
OKLAHOMA ACROSS ARKANSAS, TENNESSEE, NORTHERN MISSISSIPPI, ALABAMA
AND GEORGIA INTO SOUTHEAST KENTUCKY, VIRGINIA AND NORTH CAROLINA.
RAINFALL ACROSS THE REGION IS EXPECTED TO AVERAGE BETWEEN 1 AND 4
INCHES OVER THE NEXT 3 DAYS, WITH LOCALLY HIGHER AMOUNTS.
COMFORTABLE AND DRY WEATHER IS EXPECTED FROM IOWA EASTWARD ACROSS
NORTHERN ILLINOIS, INDIANA AND OHIO ACROSS LOWER MICHIGAN, AS WELL
AS PORTIONS OF CENTRAL NEW ENGLAND, MAKING FOR A RATHER
COMFORTABLE JULY 4TH HOLIDAY.

SHOWERS WILL BEGIN TO CREEP NORTHWARD ACROSS THE OHIO VALLEY INTO
THE MIDDLE ATLANTIC STATES, WHILE SCATTERED SHOWERS AND
THUNDERSHOWERS WILL OCCUR OVER THE SOUTHEAST.

FARTHER WEST, SHOWERS SHOULD DIMINISH OVER THE NORTHERN PLAINS BY
THURSDAY NIGHT WHILE AFTERNOON SHOWERS AND THUNDERSTORMS WILL POP
UP ACROSS THE ELEVATED TERRAIN OF THE SOUTHWEST AND SOUTHERN
ROCKIES FOR THE NEXT SEVERAL DAYS.  ACROSS THE WEST, THE
UPPER-LEVEL RIDGE THAT HAS BEEN PERSISTENT FOR MANY DAYS WILL
CONTINUE THOUGH TEMPERATURES WILL MODERATE SLIGHTLY. BY THE END OF
THE WEEKEND, HOWEVER, A SIGNIFICANT AREA OF MUCH COOLER WEATHER
WILL POOL TO THE NORTH THE US CANADIAN BORDER AND WILL BEGIN TO
SPILL SOUTHWARD INTO THE NORTHERN ROCKIES ON SUNDAY, POSSIBLY
BRINGING THE RECENT HIGH TEMPERATURE REGIME TO AN END, AT LEAST
TEMPORARILY.
