.SHORT TERM...(TONIGHT THROUGH SATURDAY)
ISSUED AT 250 PM CST WED JAN 21 2015

WEAK SURFACE TROUGH WAS SETTLING SOUTH THROUGH THE AREA WITH A FEW
RAIN/SNOW SHOWERS DEVELOPING ON THE NORTH SIDE OF THE TROUGH
ACROSS NORTHEAST NEBRASKA AND NORTHWEST IOWA. THIS TREND WILL
CONTINUE FOR AT LEAST A COUPLE HOURS THIS EVENING WITH ACTIVITY
DIMINISHING AS CYCLONIC FLOW WEAKENS AND SURFACE TROUGH CONTINUES
TO DAMPEN OUT. DON`T BELIEVE IT WILL BE MEASURABLE WITH JUST TRACE
AMOUNTS EXPECTED.

OTHERWISE...HIGH PRESSURE RIDGE COMES IN QUICKLY BEHIND THE TROUGH
WITH WEST SOUTHWEST FLOW DEVELOPING AGAIN THURSDAY AND FRIDAY
AHEAD OF THE NEXT TROUGH EXPECTED TO ENTER THE AREA. THIS SHOULD
KEEP TEMPS WELL ABOVE NORMAL WITH HIGHS IN THE UPPER 30S TO LOWER
40S THURSDAY...AND UPPER 40S TO LOWER 50S ON FRIDAY. BOTH THE NAM
AND ECMWF ALSO SUGGEST ISOLATED SPRINKLES COULD DEVELOP WITH THE
TROUGH PASSAGE FRIDAY AFTERNOON WHEN DAYTIME INSTABILITY IS
MAXIMIZED.

WESTERLY FLOW CONTINUES SATURDAY WITH ANOTHER VERY MILD DAY WITH
HIGHS IN THE UPPER 40 TO LOWER 50S...AHEAD OF THE NEXT CLIPPER
THAT QUICKLY SWEEPS THE AREA SATURDAY NIGHT.

.LONG TERM...(SATURDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 250 PM CST WED JAN 21 2015

FAST MOVING CLIPPER STILL LOOKS LIKE IT COULD BRING A CHANCE OF
RAIN OR SNOW SATURDAY NIGHT. THE ECMWF IS NOW DRY THOUGH...THUS
OVERALL CHANCES ARE ON A DOWNWARD TREND. HIGH TEMPS STILL REMAIN
VERY MILD SUNDAY THROUGH TUESDAY WITH HIGHS IN THE UPPER 40S TO
MID 50S. A WEAK FRONT COULD COOL US OFF BY WEDNESDAY...BUT STILL
WELL ABOVE NORMAL.
