...SHOWERS AND THUNDERSTORMS FOR THE GREAT LAKES-NORTHEAST -- SOME
MAY BE STRONG TO SEVERE...

...ADDITIONAL HEAVY RAINS POSSIBLE FOR THE SOUTHEAST...

...COOLER TEMPERATURES AHEAD FOR THE NORTHWEST...

LATE THIS AFTERNOON AND EVENING, SHOWERS AND THUNDERSTORMS WILL
CONTINUE TO MOVE OUT AHEAD OF AN AREA OF LOW PRESSURE MOVING
ACROSS THE UPPER GREAT LAKES INTO SOUTHEASTERN CANADA.  SOME OF
THESE STORMS MAY BE STRONG TO SEVERE AND PRODUCE LOCALLY HEAVY
RAINS.  AS THIS LOW LIFTS INTO CANADA OVERNIGHT SUNDAY INTO
MONDAY, STORMS ARE EXPECTED TO DEVELOP ALONG THE TRAILING COLD
FRONT AS IT PUSHES EAST FROM THE LOWER GREAT LAKES REGION ACROSS
THE NORTHEAST.  COLD AIR FILLING IN BEHIND THE FRONT WILL RESULT
IN HIGH TEMPERATURES REMAINING 5 TO 10 DEGREES BELOW NORMAL ACROSS
MUCH OF THE UPPER MIDWEST ON MONDAY.

ADDITIONAL ROUNDS OF SHOWERS AND THUNDERSTORMS, WITH LOCALLY HEAVY
TO EXCESSIVE RAINS, CAN BE EXPECTED FROM COASTAL SOUTH CAROLINA
AND GEORGIA BACK TO THE SOUTHEAST ACROSS NORTHERN FLORIDA AND
ALONG THE EASTERN GULF COAST.  THE GREATEST POTENTIAL FOR HEAVY
RAINS IS EXPECTED TO REMAIN CENTERED ACROSS THE NORTHERN AND
CENTRAL FLORIDA PENINSULA -- WHERE TROPICAL MOISTURE POOLING ALONG
A STALLED FRONTAL BOUNDARY IS EXPECTED TO INTERACT WITH AN SLOW
MOVING AREA OF LOW PRESSURE.

FOLLOWING ANOTHER DAY OF SCATTERED SHOWERS AND THUNDERSTORMS
ACROSS PORTIONS OF CALIFORNIA, THE SOUTHWEST AND THE GREAT BASIN,
DRIER CONDITIONS ARE EXPECTED ACROSS CALIFORNIA AND THE SOUTHWEST
ON MONDAY.  SHOWERS AND THUNDERSTORMS ARE FORECAST INSTEAD TO
FOCUS FURTHER TO THE NORTH AND EAST.

SOME STORMS MAY DEVELOP ACROSS PORTIONS OF THE PACIFIC NORTHWEST
AND THE NORTHERN ROCKIES.  BY LATE MONDAY INTO TUESDAY, A COLD
FRONT DROPPING FROM THE NORTHWEST WILL BEGIN TO IMPACT THE REGION
-- BRINGING AN END TO THE STRETCH OF WELL-ABOVE NORMAL
TEMPERATURES FELT ACROSS THE REGION.
