NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
312 AM CST SUN JAN 2 2011
.DISCUSSION...
MAIN FORECAST CHALLENGE THROUGH THE PERIOD WILL BE TEMPS. SEVERAL
CLIPPERS ARE FORECAST TO MOVE THROUGH THE NORTHERN PLAINS BRINGING
SOME LIGHT SNOW WITH EACH ONE...BUT SENSIBLE WEATHER SHOULD REMAIN
NORTH OF THE CWFA.
TEMPS EARLY THIS MORNING HAVE BEEN QUITE VARIABLE...BOUNCING
UP/DOWN WITH NOT MUCH JUSTIFICATION. OVERALL SURFACE FLOW SHOULD
BE WEST/SOUTHWEST TODAY...WITH SKIES RANGING FROM MOSTLY CLEAR
ALONG THE KS/NE BORDER...TO PARTLY TO MOSTLY CLOUDY ALONG THE
NE/SD BORDER IN RESPONSE TO THE FIRST WAVE MOVING THROUGH THE
NORTHERN PLAINS TODAY. TEMPS WILL REMAIN IN THE LOWER 20S ACROSS
NORTHEAST NEBRASKA WHERE 2 TO 4 INCHES OF SNOW REMAINS ON THE
GROUND...BUT WILL FORECAST 25 TO 30 ELSEWHERE.
FOR TONIGHT...WEST SOUTHWEST SURFACE FLOW WILL CONTINUE WHILE THE
SECOND WAVE MOVES THROUGH THE DAKOTAS...AGAIN BRINGING SOME SNOW
TO AREAS WELL NORTH OF THE CWFA. COULD AGAIN BE SOME CLOUDS
NORTHERN CWFA WHILE SOUTHERN AREAS REMAIN MOSTLY CLEAR. THIS COULD
AGAIN RESULT IN SOME FLUCTUATING TEMPS OVERNIGHT.
FOR MONDAY...SURFACE FLOW BECOMES NORTHWEST IN RESPONSE TO THE
WAVE PASSING TO THE NORTH. THIS IS MORE OF A DOWNSLOPING
COMPONENT...THUS TEMPS MAY BE ABLE TO RISE INTO THE MID 20S ACROSS
NORTHEAST NEBRASKA...AND INTO THE LOWER 30S ELSEWHERE. DECIDED TO
REMOVE THE FLURRIES FROM THE NORTHERN CWFA MONDAY NIGHT SINCE THE
SURFACE LOW APPEARS TO BE FAR ENOUGH TO THE EAST/NORTHEAST BY THEN
WITH HIGH PRESSURE BUILDING OFF THE FRONT RANGE.
STILL A SOMEWHAT STAGNANT PATTERN THROUGH THE END OF THE WEEK AS A
COUPLE MORE CLIPPERS MOVE THROUGH THE NORTHERN PLAINS. IF THEY
PRODUCE ANY SNOW...IT SHOULD EITHER REMAIN NORTH OF THE AREA...OR
THE CONFIDENCE IS TOO LOW TO MENTION ATTM.
