DISCUSSION...

TEMPERATURES WILL BE THE PRIMARY CONCERN IN THE SHORT TERM AS
SNOW COVER IS EXPECTED TO HOLD TEMPS DOWN THE NEXT COUPLE OF
DAYS.

SURGE OF COLD AIR WILL SPREAD ACROSS THE PLAINS REGION TODAY
ON STRONG NORTHWEST WINDS AHEAD OF HIGH PRESSURE BUILDING SOUTH
INTO THE CENTRAL PLAINS. WINDS ARE EXPECTED TO APPROACH ADVISORY
CRITERIA TODAY IN PARTS OF NORTHEAST NEBRASKA THEN DROP OFF
TONIGHT AS AXIS OF HIGH PRESSURE SETTLES OVER EASTERN NEBRASKA.
SOME INCREASE IN CLOUDS ON WEDNESDAY ASSOCIATED WITH WARM
ADVECTION AS LEE TROUGH DEVELOPS OVER THE WESTERN HIGH PLAINS AND
HIGH PRESSURE MOVES EAST INTO THE MISSISSIPPI VALLEY. THURSDAY
LOOKS TO BE MUCH WARMER ALTHOUGH WEAK SURFACE FLOW WILL LIMIT
MIXING. ABUNDANT SUNSHINE AND HIGH SUN ANGLE SHOULD MAKE SHORT
WORK OF REMAINING SNOW COVER ACROSS THE AREA WITH INCREASING
BOUNDARY LAYER MOISTURE DUE TO SNOW MELT. WARM AIR REMAINS OVER
THE AREA THURSDAY NIGHT AND WITH LIMITED SNOW COVER BY THEN SEE
LITTLE CHANCE OF ANY SIGNIFICANT FOG.

IN THE EXTENDED PERIOD TEMPERATURES AGAIN START TO TREND COLDER
AS ANOTHER COLD FRONT MOVES INTO THE AREA FRIDAY NIGHT. SHORTWAVE
ENERGY MAY PRODUCE SOME LIGHT PRECIP SATURDAY AFTERNOON INTO
SATURDAY NIGHT OVER THE AREA BUT BETTER FORCING APPEARS TO STAY
TO THE SOUTH ACROSS KANSAS AND MISSOURI. LIMITED CONFIDENCE 
IN FORECAST FOR SUNDAY AND BEYOND AS MODELS DIFFER ON TIMING AND
STRENGTH OF UPPER WAVE MOVING INTO THE REGION WITH EURO
SIGNIFICANTLY DEEPER AND STRONGER WITH ITS SOLUTION.
