***STATIONARY FRONT REMAINS OVER EAST-CENTRAL U.S.***

***SCATTERED SHOWERS AND STORMS FOR MANY AREAS***

***SOME IMPROVEMENT IN THE WESTERN HEAT WAVE***

A QUASI-STATIONARY FRONTAL BOUNDARY IS EXPECTED TO REMAIN SITUATED
FROM ARKANSAS TO THE MID-ATLANTIC FOR THIS WEEKEND.  THE HEAT AND
SUMMER-LIKE HUMIDITY WILL REMAIN SOUTH OF THE BOUNDARY, AND COOLER
CONDITIONS TO THE NORTH.  THIS FRONT WILL SERVE AS A FOCUSING
MECHANISM FOR ORGANIZED AREAS OF RAINFALL AND THUNDERSTORMS, AND
SCATTERED ACTIVITY ALONG THE GULF COAST AND OVER FLORIDA.  THE
HEAVIEST RAIN IS EXPECTED TO DEVELOP FROM ARKANSAS TO NORTH
CAROLINA, WHERE RAINFALL AMOUNTS IN EXCESS OF AN INCH WILL BE
POSSIBLE.   A FEW SEVERE THUNDERSTORMS WILL ALSO BE POSSIBLE.

FOR THE WESTERN U.S., DIURNALLY DRIVEN SHOWERS AND STORMS WILL
CONTINUE TO BE PRESENT EACH AFTERNOON AND EVENING ACROSS THE
FOUR-CORNERS REGION AND EXTENDING SOUTHWARD INTO MEXICO IN
RESPONSE TO MONSOONAL MOISTURE IN PLACE.  ISOLATED THUNDERSTORMS
ARE ALSO POSSIBLE ACROSS THE HIGHER ELEVATIONS OF NORTHERN
CALIFORNIA, OREGON, AND WASHINGTON.  A COLD FRONT MOVING SOUTHWARD
THROUGH THE NORTHERN ROCKIES AND PARTS OF THE PACIFIC NORTHWEST
WILL RESULT IN A WELCOME ABATEMENT TO THE EXCESSIVE HEAT THIS
WEEKEND, ESPECIALLY FROM WASHINGTON STATE TO WESTERN MONTANA.
THIS SAME FRONT WILL LIKELY PRODUCE A BAND OF SHOWERS AND STORMS
FOR THE NORTHERN PLAINS ON SUNDAY.
