...HEAVY RAIN AND STRONG STORMS LIKELY FROM THE LOWER MISSISSIPPI
VALLEY TO THE MID-ATLANTIC THROUGH SATURDAY...

...SEVERE THUNDERSTORMS POSSIBLE EAST OF CENTRAL ROCKIES TONIGHT...

A WAFFLING FRONTAL BOUNDARY WILL STRETCH FROM THE MID-ATLANTIC
ACROSS TO THE CENTRAL ROCKIES THROUGH THE WEEKEND, RESULTING IN
NUMEROUS SHOWERS AND THUNDERSTORMS FROM THE MIDWEST/GULF STATES TO
THE EASTERN SEABOARD. THESE STORMS WILL HAVE PLENTY OF HIGH
HUMIDITY TO WORK WITH SOUTH OF THE FRONT, AND A FEW SEVERE STORMS
ARE LIKELY TO DEVELOP. A WIDE SWATH ALONG THE FRONTAL BOUNDARY
WILL HAVE AN INCREASED RISK FOR HEAVY RAINFALL, WHICH MAY LEAD TO
SITUATIONS OF FLASH FLOODING. SLIGHTLY COOLER AND LESS MOIST AIR
WILL BE IN PLACE THIS WEEKEND ACROSS THE NORTHERN TIER STATES.

ACROSS THE WESTERN U.S., SCATTERED SHOWERS AND STORMS ARE EXPECTED
TO DEVELOP DURING THE AFTERNOONS AND EVENINGS, WITH THE BEST
CONCENTRATION ACROSS THE ELEVATED REGIONS OF ARIZONA AND NEW
MEXICO WITH MOISTURE FROM THE MONSOON. A WEAK COLD FRONT IS
FORECAST TO BRING COOLER CONDITIONS FOR THE PACIFIC NORTHWEST
GOING INTO THE WEEKEND.
