.DISCUSSION...
NO MAJOR ISSUES UNTIL LATE SUNDAY NIGHT AND MONDAY AS THE NEXT
FRONT MOVES INTO THE REGION.
NORTHWEST FLOW TODAY AS ONE MORE UPPER TROUGH MOVES OUT OF THE
NORTHERN PLAINS INTO THE MID MISSISSIPPI RIVER VALLEY...WHICH DOES
HAVE SOME SCT/BKN MID CLOUDS THAT MAY MOVE THROUGH OUR NORTHERN
CWFA EARLY THIS MORNING. OTHERWISE...TEMPS ARE EXPECTED TO WARM
INTO THE 40S MAINLY...SLIGHTLY COOLER TO THE NORTHWEST THOUGH.
AS THE RIDGE FLATTENS OVERNIGHT AND SURFACE WINDS BACK IN RESPONSE
TO THE NEXT APPROACHING TROUGH...TEMPS SHOULD DIP INTO THE TEENS
AND 20S...BUT AGAIN REBOUND NICELY INTO THE MID 40S/LOWER 50S FOR
BOTH SATURDAY AND SUNDAY.
REGARDING THE ARRIVAL OF THE NEXT SYSTEM...THE GFS SEEMS PERHAPS
JUST SLIGHTLY TOO AGGRESSIVE WITH THE TIMING...BRINGING IN A CHANCE
OF PRECIP AFTER MIDNIGHT SUNDAY NIGHT...WHILE THE NAM/ECMWF TEND
TO HOLD THINGS BACK JUST A BIT UNTIL MONDAY. FOR CONSISTENCY...DID
NOT MAKE MANY CHANGES TO THAT PERIOD...WITH MODELS STILL SUPPORTING
AT LEAST A SMALL CHANCE OF RAIN CHANGING TO SNOW...ALTHOUGH BEST
MOISTURE AND DYNAMICS STILL APPEAR TO GO NORTH OF THE CWFA AT THIS
TIME. MODELS ARE EVEN HINTING THAT BECAUSE OF THE LACK OF DEEP
LAYER MOISTURE THAT MONDAY MAY BE MORE OF A DAY WITH DRIZZLE AND
POSSIBLY FREEZING DRIZZLE AGAIN WHERE SURFACE TEMPS STRUGGLE TO
REACH FREEZING ACROSS NORTHEAST NEBRASKA...ALTHOUGH WILL WAIT
ANOTHER FORECAST CYCLE BEFORE MAKING THOSE CHANGES ATTM.
