SHORT RANGE FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
418 AM EDT WED OCT 1 2014

VALID 12Z WED OCT 1 2014 - 12Z FRI OCT 3 2014

***STRONG COLD FRONT OVER THE GREAT PLAINS***

***SHOWERS AND SOME MOUNTAIN SNOW FOR THE ROCKY MOUNTAINS***

***SOME SHOWERS FOR THE NORTHEAST U.S. THROUGH THURSDAY***

THE MAIN WEATHER MAKER ACROSS THE CONTINENTAL U.S. WILL BE A
STRONG COLD FRONT ACROSS THE PLAINS AND MIDWEST WITH A DEVELOPING
SURFACE LOW ALONG IT.  THIS LOW IS THEN FORECAST TO TRACK FROM THE
CENTRAL PLAINS TO THE UPPER GREAT LAKES BY FRIDAY MORNING, WITH A
SECONDARY COLD FRONT BEHIND THIS FRONT DROPPING SOUTHWARD FROM
MONTANA.

IN TERMS OF SENSIBLE WEATHER, THERE WILL LIKELY BE MULTIPLE ROUNDS
OF SHOWERS AND THUNDERSTORMS EXTENDING FROM OKLAHOMA TO THE UPPER
MIDWEST.  LOCALLY HEAVY RAINFALL WILL ALSO BE POSSIBLE AHEAD OF
THE COLD FRONT WHERE MOISTURE CONVERGENCE IS MAXIMIZED.  A FEW
SEVERE STORMS ARE POSSIBLE WITH THE SURGE OF WARM AND HUMID AIR IN
THE WARM SECTOR OF THIS SYSTEM.

ELSEWHERE ACROSS THE COUNTRY, SHOWERS FROM TIME TO TIME CAN BE
EXPECTED OVER THE NORTHEAST U.S. AS A WEAK UPPER LEVEL LOW
COMBINES WITH MOISTURE ADVECTING WESTWARD FROM THE ATLANTIC OCEAN.
 SCATTERED SHOWERS AND STORMS ARE IN THE FORECAST FOR THE CENTRAL
GULF COAST AND FLORIDA.  OUT WEST OVER THE NORTHERN ROCKIES, SOME
HIGH ELEVATION SNOW SHOWERS ARE LIKELY ABOVE 8000 FEET WITH
LINGERING MOISTURE AND COLD AIR FROM THE DEPARTING UPPER LEVEL LOW
OVER THE DAKOTAS.
