.DISCUSSION...
TEMPERATURES WILL CONTINUE TO BE THE PRIMARY FOCUS IN THE SHORT TERM
PORTION OF THE FORECAST AS WELL AS THE EXTENDED.
WEAK HIGH PRESSURE WAS LOCATED OVER THE AREA THIS MORNING WITH A
BAND OF LOW CLOUDS PUSHING SLOWLY EAST OUT OF CENTRAL NEBRASKA.
SATELLITE LOOP HAS SHOWN BACK EDGE OF CLOUDS MAKING STEADY
PROGRESS SO FAR AND SHOULD BE NEAR THE EASTERN BORDER BY 12Z IF
CURRENT TRENDS CONTINUE. SOME FOG POTENTIAL AS SKIES CLEAR OVER
THE SNOW COVER. WILL MONITOR PRIOR TO ISSUANCE BUT ADD MENTION OF
PATCHY FOG OVER AT LEAST THE WESTERN PART OF THE CWA THROUGH MID
MORNING. WEAK COLD FRONT THEN BEGINS TO MOVE INTO NORTHERN PORTION
OF THE CWA LATE THIS AFTERNOON WITH INCREASING CLOUDS. HAVE
CONTINUED TO CARRY MENTION OF SLIGHT POPS FOR LIGHT SNOW AS FRONT
DROPS SOUTH ACROSS THE AREA TONIGHT.
SMALL POCKET OF HIGH PRESSURE MOVES ACROSS ON WEDNESDAY WITH A
WARM FRONT DEVELOPING OVER THE WESTERN HIGH PLAINS AS NEXT CLIPPER
BEGINS TO DROP SOUTHEAST OUT OF CANADA AND HEADS TOWARD THE UPPER
MIDWEST ON THURSDAY AND THURSDAY NIGHT. THIS SHOULD ALLOW MILD
PACIFIC AIR TO SPREAD BACK INTO THE AREA ON THURSDAY WITH
TEMPERATURES CLIMBING INTO THE 30S AND 40S. FORECAST SOUNDINGS
FROM THE GFS AND SREF SUGGEST MAINLY SUNNY CONDITIONS AND WITH
SIGNIFICANT SNOW MELT ON MONDAY WOULD EXPECT TEMPERATURES TO BE
ABLE TO AT LEAST REACH SIMILAR HIGHS ON THURSDAY SO LATEST
GUIDANCE LOOKS PRETTY GOOD.
SOME TIMING ISSUES SHOWING UP IN THE 00Z EXTENDED MODELS REGARDING
NEXT SHOT OF COLDER AIR COMING DOWN SUNDAY INTO EARLY NEXT WEEK.
LITTLE CHANGE AT THIS TIME OTHER THAN TO BACK OFF ON COOLING FOR
SATURDAY AND SUNDAY MORNING.
