A COLD FRONT CURRENTLY MOVING THROUGH THE EASTERN U.S. WILL BE  
ACCOMPANIED BY SHOWERS AND PERHAPS A FEW THUNDERSTORMS BEFORE  
MOVING INTO THE WESTERN ATLANTIC BY WEDNESDAY MORNING WITH  
CLEARING IN ITS WAKE. THE SOUTHERN PORTION OF THE FRONT WILL STALL  
ACROSS THE GULF COAST STATES AND SOUTHERN PLAINS THROUGH THURSDAY  
KEEPING THESE LOCATIONS UNSETTLED WITH SCATTERED SHOWERS AND  
THUNDERSTORMS.  
 
MEANWHILE, A SERIES OF WEAK REINFORCING SHOTS OF COLDER AIR WILL  
FILTER INTO THE GREAT PLAINS FROM THE NORTH ALLOWING FOR A COOLING  
TREND IN HIGH TEMPERATURES INTO THURSDAY FOR MANY LOCATIONS  
BETWEEN THE ROCKIES AND THE APPALACHIANS. HIGH TEMPERATURE  
DEPARTURES WILL RANGE BETWEEN 10 TO 20 DEGREES BELOW EARLY  
NOVEMBER AVERAGES ON WEDNESDAY (NORTHERN PLAINS) AND THURSDAY  
(ENTIRE GREAT PLAINS). WITH COLDER TEMPERATURES IN PLACE, AN UPPER  
LEVEL DISTURBANCE IS EXPECTED TO PRODUCE 3-6 INCHES OF SNOW  
(LOCALLY HIGHER) FOR THE NORTHERN ROCKIES THROUGH WEDNESDAY  
MORNING WITH ACCUMULATING SNOW IMPACTING NEBRASKA AND KANSAS LATE  
WEDNESDAY NIGHT INTO THURSDAY. THE KANSAS/NEBRASKA ACCUMULATIONS  
ARE ONLY EXPECTED TO BE A FEW INCHES, BUT THIS WILL BE THE SECOND  
OR THIRD SNOW STORM FOR THE CENTRAL PLAINS SINCE MID-OCTOBER, A  
REGION WHICH HAS HAD AN EARLY START TO THE WINTER WEATHER SEASON.  
 
HIGH PRESSURE AND SLIGHTLY COOLER AIR WILL WORK ITS WAY INTO THE  
INTERMOUNTAIN WEST FOR WEDNESDAY INTO THURSDAY, ALLOWING FOR  
INCREASING WINDS FOR SECTIONS OF CENTRAL TO NORTHERN CALIFORNIA.  
PORTIONS OF THE SACRAMENTO VALLEY INTO THE SAN FRANCISCO BAY ARE  
UNDER A RED FLAG WARNING GIVEN AN INCREASED THREAT OF WILD FIRES  
BEGINNING TONIGHT AND EXTENDING THROUGH THE DAY ON WEDNESDAY GIVEN  
LOW RELATIVE HUMIDITIES AND GUSTY WINDS.
