***SHOWERS AND THUNDERSTORMS FROM THE NORTHERN PLAINS TO NEW
ENGLAND***

***LESS THUNDERSTORM COVERAGE ACROSS THE SOUTHEAST U.S.***

***HEAT WAVE ENDING FOR THE PACIFIC NORTHWEST***

A COLD FRONT PROGRESSING EASTWARD TOWARDS THE EAST COAST IS
EXPECTED TO HAVE A BROKEN BAND OF SHOWERS AND STORMS FROM THE
SOUTHERN APPALACHIANS TO EASTERN NEW ENGLAND ON TUESDAY.  SOME OF
THESE STORMS MAY BE STRONG TO SEVERE AND PRODUCE LOCALLY HEAVY
RAINFALL.  COOLER AIR FILLING IN BEHIND THE FRONT WILL RESULT IN A
RETURN TO MORE PLEASANT CONDITIONS FOR THE EASTERN U.S. BY THE
MIDDLE OF THE WEEK.

AFTER SEVERAL DAYS OF HEAVY RAIN AND THUNDERSTORMS ACROSS FLORIDA
AND ADJACENT PARTS OF THE SOUTHEAST U.S., THINGS WILL BE LESS
ACTIVE GOING INTO TUESDAY AND WEDNESDAY AS THE SURFACE TROUGH
WEAKENS.  THE HEAVIEST RAINFALL SHOULD REMAIN OFFSHORE OVER THE
GULF STREAM WATERS.  HOWEVER, DIURNALLY DRIVEN CONVECTION REMAINS
LIKELY EACH AFTERNOON NEAR THE GULF COAST.

SOME STORMS ARE EXPECTED TO DEVELOP ACROSS PORTIONS OF THE PACIFIC
NORTHWEST AND THE NORTHERN ROCKIES.  A COLD FRONT DROPPING FROM
THE NORTHWEST WILL BEGIN TO IMPACT THE REGION, BRINGING AN END TO
THE STRETCH OF WELL-ABOVE NORMAL TEMPERATURES.  THUNDERSTORMS ARE
ALSO EXPECTED TO DEVELOP ACROSS THE CENTRAL PLAINS AND EXTENDING
INTO MISSOURI.
