...DRIER CONDITIONS UNFOLDING ACROSS THE NORTHEAST AND
MID-ATLANTIC...

...SHOWERS AND THUNDERSTORMS TO PERSIST ACROSS THE SOUTHEAST...

...FLASH FLOODING POSSIBLE FOR PORTIONS OF THE SOUTHWESTERN U.S
INTO THE PLAINS...

...ABOVE AVERAGE TEMPERATURES EXPECTED FOR THE PACIFIC NORTHWEST...

A COLD FRONT, PRECEDED BY SHOWERS AND THUNDERSTORMS, WILL CONTINUE
TO PUSH THROUGH THE REMAINDER OF THE NORTHEAST AND MID-ATLANTIC
STATES THIS EVENING.  WHILE DELIVERING DRIER AIR, TYPICAL
SUMMERTIME TEMPERATURES ARE EXPECTED TO PERSIST ACROSS MUCH OF THE
REGION THROUGH THE REMAINDER OF THE WEEK.

FURTHER TO THE SOUTH, THE FRONT IS EXPECTED TO STALL ACROSS THE
SOUTHEAST AND ALONG THE GULF COAST BACK INTO TEXAS.  VERY MOIST,
UNSTABLE AIR ALONG AND SOUTH OF THE BOUNDARY WILL CONTINUE TO
SUPPORT SHOWERS AND THUNDERSTORMS ACROSS THE SOUTHEAST AND CENTRAL
GULF COAST REGIONS.  WHILE MUCH OF THE ACTIVITY IS EXPECTED TO BE
SCATTERED IN NATURE, WEAK DISTURBANCES ALOFT MAY HELP TO PRODUCE
SOME ORGANIZED STORMS, PARTICULARLY ALONG THE EASTERN AND CENTRAL
GULF COAST REGIONS.

FURTHER WEST, AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO CONTINUE BOTH DAYS ACROSS PORTIONS OF THE SOUTHERN
ROCKIES, THE DESERT SOUTHWEST AND SOUTHERN CALIFORNIA.  SOME OF
THESE STORMS MAY PRODUCE LOCALLY HEAVY AMOUNTS, RESULTING IN
EXCESSIVE RUNOFF AND FLASH FLOODING.  SOME STORMS DEVELOPING
ACROSS THE MOUNTAINS OF NORTHERN NEW MEXICO AND SOUTHERN COLORADO
MAY PROPAGATE EASTWARD, DROPPING HEAVY RAINS AS THEY MOVE INTO
SOUTHWESTERN KANSAS AND THE OKLAHOMA AND TEXAS PANHANDLE REGIONS.

ACROSS THE NORTHWEST, LITTLE CHANGE IS EXPECTED OVER THE NEXT FEW
DAYS AS HIGH PRESSURE AT THE MID AND UPPER-LEVELS OF THE
ATMOSPHERE WILL KEEP DRY CONDITIONS AND ABOVE AVERAGE TEMPERATURES
IN PLACE ACROSS THE REGION. AFTERNOON HIGH TEMPERATURES WILL BE AS
MUCH AS 10 TO 15 DEGREES ABOVE AVERAGE AT MANY LOCATIONS, WITH
TEMPERATURES SURPASSING 100 DEGREES IN SOME AREAS.
