AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE NORTH PLATTE NE
544 AM CST WED JAN 22 2014

.SHORT TERM...(TODAY AND TONIGHT)
ISSUED AT 316 AM CST WED JAN 22 2014

MODELS CONTINUE IN GOOD AGREEMENT WITH COLD AIR PUSHING INTO THE
FORECAST AREA TODAY AND SURGING ACROSS THE FORECAST AREA TONIGHT.
MAIN FORECAST CHALLENGE WILL BE SNOWFALL TO THE WEST THIS AFTERNOON
AND EVENING AND THEN LOW TEMPERATURES TONIGHT. SOME LIGHT SNOW AND
FLURRIES TO THE NORTHWEST IN RAPID AREA EARLY THIS MORNING WITH
STRATUS FIELDS. MUCH COLDER AIR TO THE NORTHEAST OVER MINNESOTA WILL
DIVE TO THE SOUTH AND ROTATE BACK THROUGH NEBRASKA THIS AFTERNOON
AND EVENING. ON THE LEADING EDGE LATE THIS MORNING COULD SEE SOME
FLURRIES AS 1045MB SURFACE HIGH PRESSURE BEGINS TO MOVE SOUTH ACROSS
THE NORTHERN PLAINS. HRR NOT TO BULLISH ON PRECIPITATION BUT HAVE
INCLUDED FLURRIES PROGRESSING ACROSS THE FORECAST AREA FROM NORTH TO
SOUTH THROUGH THE AFTERNOON WITH FOCUS SHIFTING TO UPSLOPE LIGHT
SNOW IN THE EASTERN NEBRASKA PANHANDLE AND FAR SOUTHWEST NEBRASKA
LATE AFTERNOON INTO THE NIGHT. DEPENDING ON THE COLD AIR PUSH ANY
SNOW MAY END UP LARGELY IN NORTHEAST COLORADO AND THE WESTERN
PANHANDLE. CONFIDENCE NOT HIGH WITH LIGHT SNOW SO HAVE KEPT POPS ON
THE LOW END. MUCH COLDER TO FILTER IN TO THE FORECAST AREA OVER
NIGHT WITH SOME REPRIEVE FROM THE MINUS 20C 850MB TEMPERATURES
YESTERDAY TO MINUS 15C 850MB TEMPERATURES IN THIS RUN. CLOUD COVER
TO DECREASE FROM NORTHEAST TO SOUTHWEST OVER NIGHT WITH SOME UPSLOPE
CLOUDS LINGERING OVER SOUTHWEST NEBRASKA THROUGH SUNRISE. WITH THE
CLOUD COVER HAVE KEPT SLIGHTLY WARMER TEMPERATURES SOUTHWEST WITH
THE REST OF THE FORECAST AREA FALLING BELOW ZERO OVER NIGHT.
APPARENT TEMPERATURES INDICATING A MARGINAL WIND CHILL ADVISORY FOR
NORTH CENTRAL AFTER 06Z. CONFIDENCE IS NOT REAL HIGH AND WILL LEAVE
HIGHLIGHTS FOR LATER FORECASTS. VERY COLD START TO THE DAY.

.LONG TERM...(THURSDAY THROUGH TUESDAY)
ISSUED AT 315 AM CST WED JAN 22 2014

12Z THURSDAY AND BEYOND. THE EXTENDED PERIODS WILL START OFF COLD AS
ARCTIC HIGH PRESSURE WILL BE IN CONTROL ACROSS THE NORTHERN AND
CENTRAL PLAINS. HOWEVER...UNDER A PROGRESSIVE REGIME...THE 1048MB
HIGH WILL QUICKLY DIVE TO THE SOUTH SOUTHEAST THROUGH THE DAY AS
SHORTWAVE RIDGING ALOFT BUILDS INTO THE NORTHERN PLAINS.
TEMPERATURES WILL ONCE AGAIN BE CHILLY ON THURSDAY...WITH HIGHS
ONLY IN THE TEENS AND 20S FROM EAST TO WEST RESPECTIVELY. HOWEVER
STRONG WAA ASSOCIATED WITH THE SHORTWAVE RIDGING WILL BE BUILDING
FROM THE WEST...AS 850 TEMPERATURES WARM MORE THAN 20 DEGREES
CELSIUS IN JUST 24 HOURS FROM 12Z THURSDAY TO 12Z FRIDAY. THUS
HIGHS ON FRIDAY WILL RESPOND BY WARMING INTO THE UPPER 40S TO
LOWER 50S ACROSS THE ENTIRE CWA. IN ADDITION TO THE WARMING...WIND
SPEEDS MAY BE AN ISSUE...WHICH WOULD INCREASE RANGE FIRE SPREAD
POTENTIAL. MODELS ARE KEYING IN ON A TIGHT PRESSURE GRADIENT
ACROSS THE STATE ALONG WITH THE PASSAGE OF A STOUT PV ANOMALY ATOP
THE NORTHERN PLAINS. MOMENTUM OF 40-50KTS IS SHOWN AT H85 BY MID-
AFTERNOON ACROSS MUCH OF THE CWA. PROXIMITY SOUNDINGS REVEAL
FAIRLY LIMITED MIXING HOWEVER...SO NOT EXPECTING TO REACH THE FULL
MOMENTUM POTENTIAL. ATTM...NOT EXPECTING THE NEED FOR A WIND
ADVISORY...BUT COULD BE CLOSE AS GUSTS IN THE 25-30KT RANGE ARE
ANTICIPATED. OTHERWISE INCREASED FORCING ASSOCIATED WITH THE
CLIPPER SYSTEM MAY ALLOW FOR LIGHT QPF ACROSS OUR NORTHERN
ZONES...BUT MOISTURE PROFILES ARE NOT OVERLY SUPPORTIVE OF
ANYTHING MORE THAN SPRINKLES ATTM. SATURDAY SHOULD BE FAIRLY NICE
FOR MOST LOCATIONS ACROSS THE CWA. THERE WILL BE A GOOD
TEMPERATURE GRADIENT FROM WEST TO EAST ACROSS THE FORECAST
AREA...AS THE DEPARTING CLIPPER PULLS ARCTIC AIR SOUTH ACROSS THE
MISSOURI VALLEY AND POINTS EAST. HIGHS SATURDAY WILL RANGE FROM
THE MID 50S ACROSS SOUTHWEST NEBRASKA...TO THE LOWER 40S FOR OUR
NORTHEASTERN ZONES. WITH A STEADY TAP OF WAA IN ADVANCE OF THE
NEXT QUICK HITTING WAVE...LOWS SUNDAY MORNING WILL BE FAIRLY
MILD...EXPECTING LOWER 30S FOR MOST LOCATIONS. SUNDAY WILL BE
ANOTHER TRANSITIONAL DAY...AND COULD BE INTERESTING.
WARM...DRY...AND POTENTIALLY VERY WINDY CONDITIONS ARE FORECAST
ACROSS MUCH THE CWA...LEADING TO ADDITIONAL WIND/FIRE CONCERNS.
HIGHS WILL BE MODERATED HOWEVER BY A STRONG COLD FRONT THAT WILL
USHER IN ANOTHER SIGNIFICANT COOLDOWN FOR EARLY NEXT WEEK....BUT
LIKE IT/S PREDECESSORS...THE WAVE AND ASSOCIATED ARCTIC HIGH TO
FOLLOW ARE QUICK HITTERS...WITH LITTLE TO NO QPF EXPECTED.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z THURSDAY MORNING)
ISSUED AT 545 AM CST WED JAN 22 2014

AVIATION CONCERNS TODAY FOCUS ON BREEZY NORTHERLY WINDS THAT WILL
DEVELOP THROUGH MID MORNING AND CONTINUE THROUGH THE DAY AND SOME
MARGINAL MVFR CEILINGS THAT ARE EXPECTED OVER NORTHERN NEBRASKA
THROUGH THE DAY WITH SOME FLURRIES ACROSS THE SANDHILLS.
CONFIDENCE IS NOT HIGH WITH FLURRY ACTION SO HAVE LEFT OUT OF TAFS
AT KVTN AND KLBF.
