AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
1126 PM CST SAT DEC 21 2013

.SYNOPSIS...
ISSUED AT 324 PM CST SAT DEC 21 2013

AT 20Z WATER VAPOR IMAGERY SHOWS THE UPPER LEVEL SYSTEM THAT IS
RESPONSIBLE FOR THE ONGOING WEATHER FROM THE SOUTHERN PLAINS THROUGH
THE NORTHEAST CONUS CENTERED OVER WESTERN TEXAS. MEANWHILE...A WEAK
SHORTWAVE TROUGH MOVED THROUGH THE NORTHERN STREAM INTO MONTANA AND
WYOMING. IMPACTS LOCALLY FROM THE SOUTHERN SYSTEM WERE
MINIMAL...WITH JUST SOME HIGH CLOUDS STREAMING INTO SOUTH CENTRAL
NEBRASKA. FROM THE NORTHERN STREAM SYSTEM...A COLD FRONT WAS LOCATED
ACROSS NORTHERN NEBRASKA. THE REAL COLD AIR WAS STILL BACK OVER THE
DAKOTAS WHERE AFTERNOON TEMPERATURES WERE STILL ONLY IN THE SINGLE
DIGITS ABOVE AND BELOW ZERO. ALSO...CLOUDS INCREASED ACROSS THE
WESTERN HALF OF THE STATE AHEAD OF THE SHORTWAVE MOVING INTO THE
PLAINS. RADAR ECHOES WERE ALSO OBSERVED FROM WESTERN NEBRASKA INTO
SOUTH DAKOTA AND WHILE NO MEASURABLE SNOW LOOKED TO BE
OCCURRING...HAVE SAW INTERMITTENT LIGHT SNOW REPORTS ACROSS WYOMING
AND WESTERN SOUTH DAKOTA THIS AFTERNOON.

&&

.SHORT TERM...(THIS EVENING THROUGH SUNDAY)
ISSUED AT 324 PM CST SAT DEC 21 2013

THE SHORTWAVE TROUGH OVER MONTANA AND WYOMING WILL PROGRESS EAST AND
ACROSS THE LOCAL AREA TONIGHT. UPWARD MOTION WILL BE AT A MAXIMUM
THIS EVENING AND DOES INTERSECT WITH HIGH MOISTURE IN THE DENDRITIC
GROWTH ZONE...ESPECIALLY OVER NORTHERN NEBRASKA. SO COULD GET SOME
DECENT SNOW TO DEVELOP. THE PROBLEM LIES WITH A DRY LAYER OF AIR
BETWEEN 850MB AND 700MB AS SEEN IN MODEL SOUNDINGS/CROSS
SECTIONS...WHICH HAS BEEN CONFIRMED FROM LAPS SOUNDINGS. THIS WOULD
SUGGEST THE SNOW WILL HAVE PROBLEMS MAKING IT TO THE SURFACE.
THEN...BY THE TIME THE COLUMN SATURATES...THE STRONG OMEGA HAS
PASSED SO MAY JUST GET SOME VERY LIGHT SNOW ONGOING THROUGH THE
OVERNIGHT HOURS. HOWEVER...IF THE COLUMN SATURATES FASTER...COULD
GET SOME LIGHT ACCUMULATIONS /MOST LIKELY A FEW TENTHS OF AN INCH/.

COLD AIR ADVECTION WILL BE ONGOING THROUGH THE DAY ON SUNDAY...WITH
THE AIRMASS CURRENTLY OVER THE DAKOTAS MOVING INTO NEBRASKA. BECAUSE
OF THIS...ONLY EXPECTING HIGHS IN THE TEENS AND LOW 20S FOR THE
MAJORITY OF THE FORECAST AREA. CLOUDS SHOULD BE PLENTIFUL ON SUNDAY
AS WELL AS LOW LEVEL MOISTURE IS NOT ABLE TO SCOUR OUT...WHICH WILL
ALSO HELP TO LIMIT WARMING. AND...ALTHOUGH MOISTURE WON/T BE
PARTICULARLY DEEP THROUGH THE DAY...THERE WILL BE SOME WEAK LIFT IN
THE LAYER AND WITH THE TEMPERATURES BEING QUITE COLD...EXPECT SOME
ISOLATED FLURRIES STILL THROUGH SUNDAY MORNING OVER THE NORTHERN
PARTS OF THE STATE. ANOTHER SHORTWAVE TROUGH WILL APPROACH THE AREA
IN THE AFTERNOON SUNDAY...WHICH WILL INCREASE THE LIFT OVER THE
PANHANDLE AND WESTERN NEBRASKA...AND WITH ENOUGH MOISTURE INDICATED
BY THE MODELS...CONTINUED THE LIGHT SNOW CHANCES IN THESE AREAS IN
THE AFTERNOON.

.LONG TERM...(SUNDAY NIGHT THROUGH SATURDAY)
ISSUED AT 324 PM CST SAT DEC 21 2013

PROGRESSIVE UPPER LEVEL PATTERN WITH LIGHT SNOW CHANCES AND
MULTIPLE FRONTAL PASSAGES HIGHLIGHT THE EXTENDED PERIOD.

ONLY MINOR ADJUSTMENTS TO POP GRIDS AS FORECAST LOOKS ON TRACK FOR
SNOW CHANCES SUNDAY NIGHT INTO MONDAY MORNING. A STRONG 120 KT JET
WILL BE ORIENTED NORTH TO SOUTH ACROSS THE EASTERN EDGE OF THE
ROCKIES SUNDAY NIGHT...PUTTING THE CWA IN A FAVORABLE AREA OF
AGEOSTROPHIC DIVERGENCE IN THE LEFT EXIT REGION OF THE JET. BEST
CHANCES FOR SNOW LOOK TO BE IN FAR SW NEBRASKA AND IN THE PANHANDLE
WHERE MODELS ARE FOCUSING A MID-LEVEL FGEN BAND. THIS STILL LOOKS
LIKE A QUICK SHOT OF LIGHT SNOW SINCE IT IS A RELATIVELY FAST MOVING
SYSTEM. IN ADDITION TO THE SNOW CHANCES SUNDAY NIGHT ALSO LOOKS
QUITE COLD AS A COLD FRONT BACKS INTO THE CWA. MODELS HAVE TRENDED
SLIGHTLY COLDER SO HAVE ADJUSTED TEMPS...WITH TEMPS -10F OR COLDER
POSSIBLE ACROSS OUR FAR NORTHERN ZONES BY SUNRISE MONDAY MORNING.

TEMPS MONDAY WILL BE 10 TO 20 DEGREES BELOW NORMAL WITH COLDEST
TEMPS OVER NORTH CENTRAL NEBRASKA WHERE HIGHS MAY STRUGGLE TO GET
OUT OF THE SINGLE DIGITS. TEMPS WILL REBOUND MONDAY NIGHT INTO
TUESDAY WITH DOWNSLOPE WESTERLY WINDS AND RIDGING ALOFT.

SNOW CHANCES RETURN TO THE FCST ACROSS OUR NORTHERN ZONES LATE
TUESDAY IN ADVANCE OF ANOTHER QUICKLY MOVING SHORTWAVE TROUGH.
THE SYSTEM WILL SEND ANOTHER COLD FRONT THROUGH THE FCST AREA
CHRISTMAS DAY. MODELS CONTINUE TO SLOW UP THE TIMING OF THE FRONT SO
WOULD NOT BE SURPRISED IF PARTS OF SW NEBRASKA STILL GET INTO THE
40S CHRISTMAS DAY. TEMPERATURES LOOK TO REBOUND BY FRIDAY WITH A
WARM END TO THE WEEK.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SUNDAY NIGHT)
ISSUED AT 1126 PM CST SAT DEC 21 2013

MVFR CEILINGS WILL CONTINUE OVER NORTHERN NEBRASKA TONIGHT WITH
AREAS OF FLURRIES. VFR CEILINGS ARE EXPECTED OVER SOUTHERN
NEBRASKA THROUGH THE NIGHT WITH SOME MVFR CEILINGS TOWARDS
SUNRISE.

.LBF WATCHES/WARNINGS/ADVISORIES...
