AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
1144 PM CST MON DEC 22 2014

.SHORT TERM...(TONIGHT THROUGH THURSDAY)
ISSUED AT 154 PM CST MON DEC 22 2014

PRECIP TYPE AND SNOW AMOUNTS WILL BE THE PRIMARY FORECAST CONCERN
INITIALLY IN THE SHORT TERM.

RAIN WAS CONCENTRATED ACROSS EASTERN PARTS OF THE FORECAST AREA
EARLY THIS AFTERNOON IN ADVANCE OF UPPER LOBE ACROSS EASTERN
NEBRASKA AT 19Z. EXPECT TEMPERATURES TO REMAIN WARM ENOUGH FOR
PRECIP TO REMAIN LIQUID THROUGH THE AFTERNOON BEFORE CHANGING OR
MIXING WITH SNOW THIS EVENING ACROSS THE NORTH. FORECAST SOUNDINGS
SUGGEST TIMING OF THE TRANSITION SOMETIME AFTER 03Z. SHORT RANGE
MODELS INDICATE UPPER LOW WILL BE LOCATED ACROSS SOUTHEAST
NEBRASKA INTO SOUTHWEST IOWA FOR MUCH OF THE NIGHT WITH PRECIP
PIVOTING FROM WESTERN IOWA INTO NORTHEAST NEBRASKA WHILE SOUTHERN
PARTS OF THE AREA SEE LIMITED PRECIP DURING THIS TIME. SOME ONE
INCH SNOW AMOUNTS POSSIBLE IN THE NORTH BY TUESDAY MORNING BUT
LACK OF COLD AIR ON THE BACK SIDE OF THE SYSTEM IS EXPECTED TO
LIMIT SNOW AMOUNTS AS TEMPERATURES HANG NEAR 30 DEGREES.

SNOW IS EXPECTED TO BECOME MORE WIDESPREAD ON TUESDAY AS JET
ENERGY DIGS TROUGH INTO CENTRAL TEXAS WITH SYSTEM TAKING ON A
POSITIVE TILT DURING THE DAY. DEFORMATION BAND INDICATED TO SET UP
TUESDAY MORNING THEN WEAKEN DURING THE AFTERNOON AS BETTER
DYNAMICS SHIFT EAST. TEMPERATURES WILL AGAIN BE A LIMITING FACTOR
AS READINGS STAY IN THE LOWER 30S IN MOST OF THE AREA. TOTAL
SNOWFALL WILL LIKELY BE IN THE 1-2 INCH RANGE WITH ISOLATED 3 INCH
AMOUNTS IN PARTS OF NORTHEAST NEBRASKA INTO NORTHWEST IOWA.
SOUTHERN PARTS OF THE AREA WILL HAVE TO WAIT UNTIL TUESDAY
AFTERNOON OR TUESDAY EVENING TO SEE THEIR MAIN PERIOD OF SNOW
WITH AMOUNTS OF UP TO AN INCH POSSIBLE BY WEDNESDAY MORNING. IT
WILL BECOME WINDY DURING THE DAY ON TUESDAY WITH WINDY CONDITIONS
EXPECTED TO CONTINUE INTO TUESDAY NIGHT.

SNOW WILL END BY WEDNESDAY MORNING IN EASTERN AREAS BUT CLOUDS
MAY LINGER ACROSS THE ENTIRE AREA FOR MUCH OF THE DAY. CLOUD COVER
IS EXPECTED TO DECREASE WEDNESDAY NIGHT INTO CHRISTMAS DAY WITH
WARMER AIR RETURNING TO THE REGION AS ANOTHER WEATHER SYSTEM
APPROACHES THE CENTRAL ROCKIES.

.LONG TERM...(THURSDAY NIGHT THROUGH MONDAY)
ISSUED AT 154 PM CST MON DEC 22 2014

THE CENTRAL ROCKIES SYSTEM WILL MOVE INTO THE PLAINS REGION
THURSDAY NIGHT INTO FRIDAY BRINGING ANOTHER CHANCE OF SOME LIGHT
SNOW TO MAINLY WESTERN AND NORTHERN PARTS OF THE REGION. THIS WILL
BE FOLLOWED BY A SERIES OF ADDITIONAL WEATHER SYSTEMS INDICATED
TO MOVE ACROSS THE REGION INTO EARLY NEXT WEEK WITH A TREND TOWARD
COLDER TEMPERATURES AND A CHANCE OF MORE LIGHT SNOW ON MONDAY.
