ACROSS THE GULF COAST STATES, AND THE OHIO AND TENNESSEE VALLEYS  
THROUGH TUESDAY...  
 
...VERY DRY, MILD AND WINDY CONDITIONS OVER THE SOUTHERN HIGH  
PLAINS WILL FOSTER AN ENHANCED FIRE DANGER RISK...  
 
WIDESPREAD SNOW AND STRONG WIND SPEEDS ARE IMPACTING MUCH OF THE  
NORTHERN HIGH PLAINS AND UPPER MISSISSIPPI VALLEY AS AN  
UPPER-LEVEL TROUGH AND SURFACE COLD FRONT MOVES EAST THROUGH THE  
THE CENTRAL U.S. BLIZZARD CONDITIONS ARE EXPECTED FROM SOUTHWEST  
NORTH DAKOTA DOWN ACROSS MUCH OF CENTRAL SOUTH DAKOTA AND FAR  
NORTHERN NEBRASKA GIVEN THE EXPECTED HIGH WINDS. OVER 1 FOOT OF  
SNOW IS EXPECTED LOCALLY WITH THIS WINTER STORM GOING THROUGH  
TUESDAY BEFORE THE SYSTEM THEN BEGINS TO MOVE TOWARD THE EASTERN  
U.S. NUMEROUS BLIZZARD AND WINTER STORM WARNINGS, ALONG WITH  
WINTER WEATHER ADVISORIES AND HIGH WIND WARNINGS ARE IN EFFECT  
FROM EASTERN MONTANA SOUTH TO KANSAS AND EAST TO WISCONSIN AND  
NORTHERN ILLINOIS. THE SNOW WILL SPREAD TO THE GREAT LAKES,  
NORTHERN OHIO VALLEY AND THE NORTHEAST BY MIDWEEK AS THE FRONT  
TRACKS TOWARD THE EAST COAST.  
 
ALONG THE TRAIL COLD FRONT, SCATTERED TO WIDESPREAD SHOWERS AND  
THUNDERSTORMS WILL DEVELOP OVER THE SOUTHERN/CENTRAL PLAINS TO THE  
MIDWEST AS SOUTHERLY FLOW FROM THE GULF TRANSPORTS MOISTURE  
NORTHWARD. THE SWATH OF PRECIPITATION WILL SPREAD EAST ACROSS THE  
OHIO AND TENNESSEE VALLEYS AND INCLUDING THE GULF COAST AND INTO  
PORTIONS OF THE MID-ATLANTIC REGION. SOME LOCALLY HEAVY RAINFALL  
WILL OCCUR, BUT RIGHT NOW THE AMOUNTS DO NOT APPEAR TO BE HEAVY  
ENOUGH TO SUPPORT MUCH IN THE WAY OF A FLOODING THREAT.  
 
GUSTY WINDS AHEAD OF A COLD FRONT AND ALSO BEHIND IT COUPLED WITH  
LOW RELATIVE HUMIDITIES WILL MAINTAIN THE THREAT FOR DANGEROUS  
FIRE WEATHER CONDITIONS. THE FIRE WEATHER THREAT SHOULD TEND TO  
SUBSIDE BY TUESDAY THOUGH AS THE WINDS BEGIN TO DIMINISH. ACROSS  
THE WESTERN U.S., TEMPERATURES WILL START OFF COOL BUT WITH HIGH  
PRESSURE BUILDING IN ACROSS THE INTERMOUNTAIN WEST SOME GRADUAL  
MODERATION CAN BE EXPECTED.
