***RAINY CONDITIONS WITH STALLED FRONT NEAR EAST COAST***

***NUMEROUS SHOWERS AND THUNDERSTORMS FOR THE ROCKIES***


A RETURN TO WARMER AND MORE HUMID WEATHER CAN BE EXPECTED FOR THE
EAST COAST STATES AS THE RECENT COOL AIR MASS LIFTS NORTHWARD INTO
CANADA.  THE FRONTAL BOUNDARY NEAR THE GULF COAST IS DEVELOPING A
WAVE OF LOW PRESSURE ALONG IT THAT IS EXPECTED TO BRING A WARM
FRONT NEAR THE MID-ATLANTIC COAST BY FRIDAY EVENING, AND THIS WILL
BRING WIDESPREAD RAIN AND EMBEDDED THUNDERSTORMS FROM THE
CAROLINAS TO SOUTHERN NEW ENGLAND.  WARM AND HUMID AIR OVER-RIDING
COOLER AIR INLAND WILL BE THE MAIN FORCING MECHANISM FOR RAIN.

FARTHER WEST ACROSS MUCH OF THE CENTRAL AND NORTHERN U.S., THE
WEATHER IS EXPECTED TO REMAIN RELATIVELY COOL AND DRY THROUGH THE
END OF THE WEEK.  A CHANCE OF SHOWERS AND THUNDERSTORMS CAN BE
EXPECTED IN THE GREAT LAKES DUE TO UPPER LEVEL SHORTWAVES AND
INSTABILITY.

FOR THE INTER-MOUNTAIN WEST, SCATTERED TO NUMEROUS SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED ACROSS NEW MEXICO AND COLORADO AS A
WEAKENING FRONTAL BOUNDARY INTERACTS WITH MONSOONAL MOISTURE TO
THE SOUTHWEST.  ISOLATED STORMS ARE EXPECTED FOR THE NORTHERN
ROCKIES AND INTO THE PACIFIC NORTHWEST, WHILE THE IMMEDIATE COAST
SHOULD REMAIN DRY THROUGH THE WEEKEND.
