...HEAVY RAIN AND A SLIGHT RISK OF SEVERE WEATHER IS POSSIBLE OVER
THE MISSISSIPPI VALLEY INTO THE OHIO VALLEY AS A STORM SYSTEM
DEVELOPS OVER THE MIDDLE OF THE COUNTRY...

...MUCH COOLER AND WINDY WEATHER IS EXPECTED TO MOVE FROM THE
NORTHERN ROCKIES ACROSS THE NORTHERN PLAINS TOWARD THE MIDWEST...

AN AREA OF ONE OR MORE LOW PRESSURE SYSTEMS IS EXPECTED TO DEVELOP
AND INTENSIFY AS IT MOVES FROM THE SOUTHERN PLAINS NORTHEASTWARD
TOWARD THE MID MISSISSIPPI VALLEY AND MIDWEST. MODERATE TO HEAVY
RAIN AND EMBEDDED THUNDERSTORMS ARE EXPECTED TO OCCUR WITH THIS
STORM SYSTEM AND AFFECT THE MISSISSIPPI VALLEY AS AN ASSOCIATED
COLD FRONT MOVES EASTWARD.  AS LOW PRESSURE INTENSIFIES OVER THE
MIDWEST ACROSS THE GREAT LAKES AND SOUTHERN CANADA, THE HEAVIEST
RAINS WILL MOVE NORTHWEST INTO WESTERN ONTARIO WHERE A CHANGE TO
SNOW IS EXPECTED.  HOWEVER, AS A STRONG COLD FRONT SWEEPS
EASTWARD, SHOWERS AND THUNDERSTORMS WILL MOVE EASTWARD ACROSS MUCH
OF THE EAST COAST ON FRIDAY INTO EARLY SATURDAY.

A MASS OF MUCH COOLER AIR WILL BEGIN TO SWEEP SOUTH AND EASTWARD
FROM THE NORTHERN ROCKIES STARTING ON EARLY THURSDAY AND WILL
CONTINUE SOUTH AND EASTWARD INTO MUCH OF THE NORTHERN AND CENTRAL
PLAINS BY EARLY FRIDAY.  MOSTLY LIGHT SNOW IS EXPECTED TO
ACCOMPANY THIS EARLY SEASON COLD OUTBREAK FROM MONTANA INTO THE
MOUNTAINS OF WYOMING. THIS CHILLY AIR MASS WILL BEGIN TO FOLLOW
THE INTENSIFYING STORM SYSTEM AND ASSOCIATED COLD FRONT MOVING
FROM THE MIDWEST TOWARD THE EAST COAST ON FRIDAY INTO EARLY
SATURDAY, BRINGING WINDY WEATHER AND QUITE COOL TEMPERATURES INTO
THE OHIO VALLEY AND APPALACHIANS BY EARLY FRIDAY. COOL WEATHER
WILL COVER MUCH OF THE EAST COAST INTO EARLY SUNDAY AS THE COLD
FRONT EVEN SWEEPS SOUTHWARD ACROSS MUCH OF FLORIDA.
