AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
1131 PM CST TUE DEC 23 2014

.UPDATE...
ISSUED AT 1124 PM CST TUE DEC 23 2014

PERSISTENT DEFORMATION-BAND PRECIPITATION HAS BEEN SHOWING SIGNS
OF DECREASING IN INTENSITY AND AREAL COVERAGE OVER THE LAST COUPLE
OF HOURS...BUT RADAR RETURNS CONTINUE TO FLARE UP FROM TIME TO
TIME ACROSS WESTERN IOWA AND ROTATE INTO EASTERN NEBRASKA. EXPECT
THIS TREND TO CONTINUE FOR SEVERAL HOURS PAST MIDNIGHT. HOWEVER
TEMPERATURES REMAIN ABOVE FREEZING IN PRECIP AREAS...SO ANY
SNOWFALL SHOULD REMAIN MINIMAL. OTHERWISE NORTHWEST WINDS GUSTING
OVER 20 MPH WILL HELP TO DRY OUT ROADS OVERNIGHT...BUT COULD STILL
SEE A FEW SLICK SPOTS IN THE MORNING AS TEMPERATURES DROP BELOW
FREEZING.

.SHORT TERM...(TONIGHT THROUGH FRIDAY)
ISSUED AT 300 PM CST TUE DEC 23 2014

BAND OF GENERALLY LIGHT MIXED PRECIP CONTINUES TO TRACK SLOWLY
SOUTH ACROSS SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AT 20Z. THIS
TREND IS EXPECTED TO CONTINUE INTO THE EVENING AS UPPER TROUGH
MOVES SLOWLY EAST. TEMPERATURES ARE IN THE MID TO UPPER 30S SO
WHATEVER SNOW DOES FALL MELTS FAIRLY QUICKLY. NDOR WEB CAMS SHOW
LITTLE TO NO SNOW COVER SOUTH OF A COLUMBUS TO TEKAMAH LINE.

LATEST RAP MODEL INDICATES A DIMINISHING TREND TO THE PRECIP THIS
EVENING WITH ONLY MINOR ACCUMULATIONS EXPECTED AS TEMPERATURES
FALL TO NEAR 32 THROUGH 06Z. STRONGER DYNAMICS SHIFT WELL EAST OF
THE AREA TONIGHT TO THE TENNESSEE AND LOWER OHIO VALLEY WITH
SHORT WAVE RIDGING BUILDING INTO THE NORTHERN PLAINS.

FORECAST SOUNDINGS SUGGEST DECREASING CLOUDS ACROSS THE AREA FOR
WEDNESDAY ALTHOUGH EASTERN AREAS MAY BE LIMITED TO LATE AFTERNOON
FOR ANY POTENTIAL VIEWING OF SUNSHINE. CLEARING TREND CONTINUES
WEDNESDAY NIGHT INTO THURSDAY BEFORE CLOUDS INCREASE ONCE AGAIN
THURSDAY NIGHT AND FRIDAY BEHIND THE NEXT COLD FRONT AND
APPROACHING UPPER TROUGH. SOME LIGHT SNOW IS LIKELY AGAIN WITH
THIS SYSTEM ON FRIDAY BUT NO MAJOR IMPACT ON TRAVEL IS EXPECTED.

.LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 300 PM CST TUE DEC 23 2014

SNOW MAY LINGER INTO FRIDAY NIGHT FOR SOUTHERN PARTS OF THE AREA
THEN DRY BUT COLD FOR THE WEEKEND. STRONG TROUGHING DEVELOPS OVER
THE CENTRAL PART OF THE NATION EARLY NEXT WEEK WITH MUCH COLDER
AIR ON TAP FOR THE END OF THE YEAR.
