AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
231 PM CST SUN DEC 5 2010
.SHORT TERM...TONIGHT THROUGH WEDNESDAY.
TEMPERATURES WILL CONTINUE TO BE THE PRIMARY FORECAST CONCERN IN
THE SHORT TERM AS HIGH PRESSURE REMAINS OVER THE AREA UNTIL LATE
IN THE PERIOD.
HIGH PRESSURE WAS CENTERED OVER EASTERN NEBRASKA AT 19Z AND IS
EXPECTED TO LINGER THROUGH MOST OF THE SHORT TERM PERIOD BEFORE
DRIFTING EAST ON WEDNESDAY IN ADVANCE OF NEXT CLIPPER SYSTEM
COMING OUT OF THE NORTHERN ROCKIES. LITTLE CHANGE TO THE FORECAST
OVERALL WITH TREND TOWARD GRADUALLY WARMER TEMPERATURES DURING THE
FIRST PART OF THE WEEK.
.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY.
NORTHWEST FLOW WILL CONTINUE ACROSS THE AREA. AN UPPER SHORT WAVE
TROUGH AND ASSOCIATED SURFACE FRONT WILL MOVE ACROSS THE AREA
WEDNESDAY NIGHT INTO THURSDAY MORNING. AT THIS TIME....NOT
EXPECTING MORE THAN SOME FLURRIES OR DRIZZLE WITH THAT SYSTEM. MORE
SIGNIFICANT UPPER TROUGH MOVES ACROSS THE AREA SATURDAY. THERE IS
GOOD AGREEMENT WITH THE GFS AND ECMWF ON THIS SYSTEM AND SHOULD
PRODUCE SNOW ACROSS THE AREA DURING THE DAY SATURDAY AND LINGER INTO
EARLY SUNDAY MORNING OVER EASTERN AREAS.

.AVIATION...
TAF SITES KOFK/KOMA/KLNK
18Z TAFS
SFC HIGH PRESSURE WL CONTINUE TO MOVE OVERHEAD TONIGHT. AREA OF MVFR
CIGS HAS MOVED OVER KOFK AND KLNK THIS AFTERNOON AND WL LIKELY PUSH
INTO KOMA EVENTUALLY. WAS THINKING THIS MIGHT BREAK UP...BUT IT HAS
BEEN FAIRLY STEADY ON ADVANCING OVER THE TAF SITES. WL LIKELY HOLD
MVFR CONDITIONS ALL THE WAY THRU THE EVENING HOURS. MODEL SOUNDINGS
INDICATE SOME OF THIS BREAKING UP OVERNIGHT...BUT NOT TOO CONFIDENT
ON THIS. WE COULD HOLD ONTO THE CIGS ALL NIGHT BASED ON UPSTREAM OBS.
