...SHOWERS AND THUNDERSTORMS WILL CONTINUE TO IGNITE AHEAD OF A
COLD FRONT SLOWLY EDGING THROUGH THE EASTERN U.S....

...HEAVY RAINS AND STRONG STORMS POSSIBLE WITH A FRONTAL BOUNDARY
SURGING NORTH THROUGH THE CENTRAL PLAINS AND MIDDLE MISSISSIPPI
VALLEY...

...MONSOONAL MOISTURE WILL CONTINUE TO FUEL WIDESPREAD SHOWER
ACTIVITY FROM THE SOUTHWEST TO THE GREAT BASIN AND CENTRAL
ROCKIES...


SHOWERS AND THUNDERSTORMS WILL CONTINUE TO IGNITE AHEAD OF AN
UNSEASONABLY STRONG COLD FRONT SLOWLY EDGING TOWARDS THE ATLANTIC
COAST WEDNESDAY NIGHT.  A WARM AND UNSTABLE AIRMASS IN PLACE
ACROSS THE EASTERN SEABOARD COULD ALLOW DEVELOPING STORMS TO
CONTAIN HEAVY DOWNPOURS AND STRONG TO SEVERE WEATHER.  THE
NORTHERN PORTION OF THE FRONT SHOULD CLEAR THE NORTHEAST AND
NORTHERN MID-ATLANTIC COASTS BY EARLY THURSDAY...LEAVING BEHIND
COOLER AND NOTICEABLY DRIER AIR IN IT`S WAKE; HOWEVER...THE
BOUNDARY WILL STRUGGLE TO PRESS SOUTH THROUGH THE
CAROLINAS...SOUTHEAST...AND GULF COAST STATES.  THE LINGERING
BOUNDARY SHOULD CAUSE CONTINUED UNSETTLED WEATHER OVER THE
SOUTHEASTERN CORNER OF THE NATION THROUGH FRIDAY.

THE TAIL END OF THE BOUNDARY STALLED OVER THE SOUTHEAST WILL
REMAIN STRETCHED THROUGH THE LOWER MISSISSIPPI VALLEY AND TEXAS
WEDNESDAY NIGHT BEFORE SURGING NORTH THROUGH THE CENTRAL PLAINS ON
THURSDAY AND INTO THE MIDDLE MISSISSIPPI VALLEY BY FRIDAY.
INCREASING MOISTURE STREAMING OUT OF THE GULF...COMBINED WITH WEAK
ENERGY STREAKING THROUGH ALOFT...SHOULD ALLOW AN ORGANIZED AREA OF
CONVECTION TO BREAKOUT TO THE NORTH OF THE BOUNDARY.  THESE STORMS
COULD BE STRONG TO SEVERE AND WILL BE CAPABLE OF PRODUCING HEAVY
RAINS.

ELSEWHERE ACROSS THE COUNTRY...MONSOONAL MOISTURE PUMPING INTO THE
INTERMOUNTAIN WEST WILL CONTINUE TO FOSTER WIDESPREAD SHOWER AND
THUNDERSTORM ACTIVITY FROM SOUTHWEST TO THE GREAT BASIN AND
CENTRAL ROCKIES.  ANOTHER UNSEASONABLY STRONG COLD FRONT WILL
BEGIN TO PLUNGE SOUTH OUT OF WESTERN CANADA...DROPPING
TEMPERATURES AS IT SINKS THROUGH THE NORTH CENTRAL U.S. LATE THIS
WEEK.
