AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
311 PM CST TUE FEB 9 2016

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY)
ISSUED AT 311 PM CST TUE FEB 9 2016

ALOFT: NNW FLOW WILL GRADUALLY BECOME MORE NW THRU TOMORROW AS
DEAMPLIFICATION OF THE WRN RIDGE/ERN TROF BEGINS. HEIGHTS WILL
RISE ABOUT 120 M. NO SIGNIFICANT PERTURBATIONS ARE ENVISIONED.

SURFACE: A STATIONARY FRONT BISECTED NEB/KS AND EXTENDED NNW INTO
THE CANADIAN PRAIRIES. THIS FRONT WILL GRADUALLY INCH E OF THE
FCST AREA OVER THE NEXT 30 HRS AS A WEAK CLIPPER DIVES SSE ALONG
IT... INTO ND BY DAWN WED AND INTO NEB IN THE AFTERNOON.

REST OF THIS AFTERNOON: M/CLOUDY. THERE IS A LONGITUDINAL BAND OF
MULTI-LAYERED CLOUDS ASSOCIATED WITH THE FRONT AND ASSOCIATED JET.

TONIGHT: M/CLOUDY. THERE IS SOME WEAK FGEN ALONG THE FRONT...AND
SOME INSTABILITY IS FCST TO DEVELOP ABOVE IT. HOWEVER...THERE IS
NO SYNOPTIC FORCING...SO LIFT IS MINIMAL. WE`VE SEEN SOME LIGHT
RADAR RETURNS OVER SD. MOST OF IT HAS NOT BEEN REACHING THE
GROUND...BUT DID MAINTAIN A SLIGHT CHANCE OF FLURRIES WELL N OF
I-80.

ANOTHER MILD NIGHT AHEAD. LOWS 6-12F ABOVE NORMAL.

WED: CLEARING FROM W-E WITH FRONTAL PASSAGE. STILL COULD SEE A
FEW FLURRIES WELL N OF I-80 FORENOON. VERY LOW CONFIDENCE IN HIGH
TEMPS. FULL SUN AND NO SNOW WOULD SUPPORT HIGHS IN THE 50S AND
60S! BUT CRUSTY SNOWCOVER IS A MAJOR COMPLICATION.

LAST SAT LOOKED VERY WARM TOO...BUT EFFECTS OF SNOWCOVER
DOMINATED AND THE TEMP PROFILE WAS HIGHLY INVERTED. SO USED BIAS
CORRECTED CONSENSUS OF MODEL 2M TEMPS WHICH OFFERS 40S OVER THE
SNOW AND 50S WHERE THERE IS LITTLE OR NO SNOW OVER N-CNTRL KS.
THIS COULD BE OVERDONE.


.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 311 PM CST TUE FEB 9 2016

THE LONG TERM IS RATHER QUIET WEATHER-WISE. OVERALL...NOTEWORTHY
ITEMS INCLUDE TEMPERATURES AND THE SMALL CHANCE FOR PRECIPITATION
TOWARDS THE END OF THE WEEK.

THE LONG TERM BEGINS WITH A BROAD TROUGH CENTERED OVER EASTERN
PARTS OF THE CONUS AND RIDGING OVER THE WEST COAST. WE WILL BE
UNDER MOSTLY NORTHWESTERLY FLOW THROUGH THE WEEK UNTIL THE RIDGE
EVENTUALLY PUSHES EAST...AND THE UPPER LEVEL FLOW BRIEFLY BECOMES
MORE ZONAL ABOVE THE CENTRAL PLAINS. A SHORT WAVE TROUGH COMES
THROUGH THIS WEEKEND. THIS WILL BE THE FOCUS FOR THE POTENTIAL
PRECIPITATION THIS WEEKEND...ALBEIT A SMALL CHANCE AT THIS TIME
AND NOTHING TO RAISE FLAGS OVER. WE CURRENTLY HAVE A SLIGHT CHANCE
FOR SNOW SHOWERS NORTH AND NORTHEAST OF THE TRI-CITIES...BUT AGAIN
NOTHING LOOKS ANYWHERE NEAR DAUNTING FOR SNOW AMOUNTS.

TEMPERATURES WILL BE NEAR NORMAL THURSDAY AND FRIDAY BEFORE WILL
COOL DOWN SATURDAY TO BELOW NORMAL AS A STRONG SURFACE HIGH PUSHES
IN FROM THE NORTH. THOSE COOL TEMPERATURES WILL BE BRIEF AS WE
WARM UP SIGNIFICANTLY TO END THE LONG TERM TO TEMPERATURES IN THE
50S TO NEAR 60 FOR PLACES ACROSS NORTH CENTRAL KANSAS.
