...SCATTERED THUNDERSTORMS CONTINUE ACROSS MUCH OF THE PLAINS AND
INTO THE MIDWEST...

...RAIN SHOWERS WILL GIVE WAY TO SUMMER-LIKE CONDITIONS IN THE
EAST...

A SLOW-MOVING LOW PRESSURE SYSTEM CONTINUES TO PROVIDE SHOWERS AND
THUNDERSTORMS OVER NEW ENGLAND THIS TUESDAY AFTERNOON.  THESE
SHOWERS ARE EXPECTED TO TAPER OFF TONIGHT AS THE LOW SLOWLY MOVES
EASTWARD OUT INTO THE ATLANTIC AND DISSIPATES.  IN THE WAKE OF
THIS SYSTEM, SUMMER-LIKE CONDITIONS ARE EXPECTED TO OVERSPREAD
MUCH OF THE EASTERN SEABOARD AS AFTERNOON TEMPERATURES ARE
FORECAST TO RISE WELL UP INTO THE 80`S TO NEAR 90 DEGREES.  ALONG
WITH THE WARM TEMPERATURES WILL BE A GRADUAL INCREASE IN HUMIDITY.

MEANWHILE, IMPULSES ASSOCIATED WITH AN UPPER-LEVEL TROUGH ARE
FORECAST TO CONTINUE INTERACTING WITH A NEARLY STATIONARY FRONT
ACROSS THE PLAINS STATES.  THE FIRST IMPULSE WILL TRIGGER SHOWERS
AND THUNDERSTORMS IN THE CENTRAL PLAINS TONIGHT WHICH WILL
GRADUALLY SPREAD INTO THE NORTHERN PLAINS, THE MIDWEST AND THE
MID-MISSISSIPPI VALLEY DURING THE NEXT COUPLE OF DAYS.  THE SECOND
IMPULSE IS FORECAST TO TRIGGER THE FORMATION OF A NEW LOW CENTER
IN THE CENTRAL HIGH PLAINS LATER ON WEDNESDAY.  THIS
WILL INCREASE THE CHANCE OF MORE SHOWERS AND THUNDERSTORMS TO FORM
IN THE CENTRAL AND SOUTHERN PLAINS ON THURSDAY AHEAD OF A
STATIONARY FRONT.

OUT WEST, SCATTERED RAIN SHOWERS MIXING WITH SNOW IN THE HIGHER
ELEVATIONS CAN BE EXPECTED FROM ACROSS THE GREAT BASIN INTO THE
CENTRAL AND NORTHERN ROCKIES AHEAD OF THE UPPER-LEVEL TROUGH
THROUGH THURSDAY.  SOME SNOW IS ALSO EXPECTED IN THE SIERRA NEVADA
THROUGH TONIGHT.  MOISTURE WILL CONTINUE TO LINGER IN THE PACIFIC
NORTHWEST.  ELSEWHERE, DRY CONDITIONS ARE EXPECTED FOR THE REST OF
THE DESERT SOUTHWEST.
