AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HASTINGS NE
1105 PM CST SUN DEC 21 2008

.AVIATION...FOR THE 06Z KGRI TAF. VFR CONDITIONS WILL DOMINATE THE
GRAND ISLAND TERMINAL TONIGHT AS SURFACE HIGH PRESSURE SITS ACROSS
THE REGION. THIS WILL BRING LIGHT WINDS AND OTHER THAN SOME
OCCASIONAL HIGH CLOUD COVER...AN UNLIMITED CEILING AND VISIBILITY.
AS THE AREA HEADS INTO MONDAY...THE LEE TROUGH WILL DEEPEN OVER
THE HIGH PLAINS IN ADVANCE OF A STRONG SYSTEM SITTING OVER THE
INTERMOUNTAIN WEST REGION. THIS WILL CAUSE WINDS TO TURN BACK
AROUND TO THE SOUTH TO SOUTHEAST AND INCREASE TO AROUND 20 TO 25
KNOTS WITH GUSTS NEAR 30 KNOTS POSSIBLE BY LATE MORNING AND
LASTING INTO THE AFTERNOON. A WEAK UPPER DISTURBANCE WILL PUSH
ACROSS THE AREA DURING THE AFTERNOON HOURS WITH A FEW SNOW
FLURRIES POSSIBLE NEAR THE TERMINAL. HOWEVER...WILL LEAVE THIS
OUT OF THE FORECAST GIVEN LOW COVERAGE OF SNOW FLURRIES. IN
ADDITION...A THICK PLUME OF CIRRUS STREAMING OFF THE CENTRAL
ROCKIES WILL SPREAD ACROSS THE REGION ON MONDAY ALTHOUGH CEILINGS
SHOULD STAY ABOVE 15 KFT.

.PREV DISCUSSION... /ISSUED 353 PM CST SUN DEC 21 2008/

SHORT TERM...TONIGHT THROUGH 12Z TUESDAY. MAIN FORECAST CONCERN
LIES WITH TEMPERATURES.

QUIET...SUNNY DAY TODAY ACROSS THE CWA THANKS TO DRY
NORTHWESTERLY FLOW IN THE UPPER LEVELS AND SURFACE HIGH PRESSURE
BUILDING INTO THE REGION FROM THE NORTH. HAVE CUT WIND CHILL ADV
BACK TO ALL BUT NORTHERN CWA...AND WILL LET RIDE TO ITS CURRENT
00Z EXP TIME. EXPECTING LITTLE TO CHANGE FOR THE OVERNIGHT HOURS
TONIGHT AND INTO EARLY MONDAY MORNING. MODELS IN GOOD AGREEMENT
SHOWING SURFACE HIGH PRESSURE CONTINUING TO BUILD IN AND DOMINATE
THE PATTERN OVER THE CWA TONIGHT. EXPECT THAT BY 06Z THE CENTER OF
THE HIGH WILL BE NEARLY OVERHEAD...AND BY 12Z HAS STARTED TO SLIDE
OFF TO THE EAST...SITTING NEAR THE NE/KS/MO BORDER. THIS MEANS A
CALM...CLEAR...AND WITH PLENTY OF RADIATIONAL COOLING...COLD
NIGHT. EXPECTING LOW TEMPERATURES TO PLUMMET BELOW ZERO ONCE
AGAIN...WITH NORTHERN AREAS POSSIBLY SEEING DOUBLE DIGITS BELOW.
AM CONCERNED ABOUT WIND CHILL...MAINLY AFTER 03-04Z TONIGHT...AND
CONSIDERED ANOTHER ADVISORY...BUT WITH HIGH SITTING OVERHEAD WINDS
WILL BE CALM FOR MOST OF THE NIGHT...AND MARGINAL FOR WC ADV
CRITERIA WHEN COLDEST TEMPS OCCUR. LATER SHIFTS WILL MONITOR WIND
TRENDS...AND ISSUE IF NECESSARY.

FOR THE REST OF MONDAY...INSERTED MENTION OF FLURRIES ACROSS THE
CWA...AS LITTLE BITS OF UPPER LEVEL ENERGY ASSOCIATED WITH A LARGER
SYSTEM OVER THE NORTHERN ROCKIES MAKE THEIR WAY INTO THE REGION.
NOT A LOT OF MOISTURE TO WORK WITH DURING THIS TIME...BUT COULDN/T
COMPLETELY RULE A FLURRY OR TWO OUT.  TOMORROW ALSO LOOKING TO BE ON
THE BREEZY SIDE...AS LEE SIDE SURFACE LOW PRESSURE STRENGTHENS AHEAD
OF THE MAIN UPPER LEVEL SYSTEM.  THIS WILL BRING AN INCREASE IN
SOUTHERLY WINDS...REALLY PICKING UP IN THE MID/LATE MORNING
HOURS...WITH ANOTHER DAY OF SPEED NEAR 15 TO 25 MPH EXPECTED.  ONE
GOOD THING IS THAT THE INCREASED SOUTHERLY FLOW WILL HELP TO BRING
WARMER AIR INTO THE REGION...WITH HIGHS STILL BELOW NORMAL...BUT
INCREASING INTO THE LOWER/MID TEENS NORTH TO LOWER 20S.

LONG TERM...12Z TUESDAY THROUGH SATURDAY. MAIN FORECAST CONCERNS
WILL BE A CHANCE OF SNOW MAINLY TUESDAY NIGHT AND TEMPERATURES.

A COLD FRONT MOVES THROUGH THE FORECAST AREA TUESDAY MORNING AND AS
THE COLD FRONT MOVES THROUGH THERE IS A WEAK UPPER LEVEL WAVE THAT
MOVES ACROSS. WITH TEMPERATURES STILL ON THE COOL SIDE...WEAK LIFT
AND SOME MOISTURE AROUND...THERE COULD BE A FEW FLURRIES. BY TUESDAY
NIGHT THE MAIN TROUGH MOVES THROUGH WITH A FAIRLY STRONG SHORT WAVE.
EXPECT THAT THERE WILL BE SOME SNOW WITH THIS SYSTEM. THE GFS IS A
LITTLE FURTHER SOUTH WITH THE UPPER LOW AND THE PRECIPITATION...BUT
BOTH GFS AND ECMWF SHOW THAT THE BEST CHANCE FOR SNOW WILL BE IN THE
SOUTHEAST PART OF THE FORECAST AREA AND THAT IS WHERE THE GREATEST
AMOUNTS OF SNOW SHOULD BE.

ON WEDNESDAY A HIGH PRESSURE SYSTEM SLIDES INTO THE AREA WITH LIGHT
WINDS AND MORE SUNSHINE. THE COLD AIR WILL REMAIN IN PLACE AND
TEMPERATURES WILL STILL REMAIN ON THE COOL SIDE. WEDNESDAY NIGHT AND
THURSDAY THE HIGH MOVES TO THE EAST...WINDS TURN TO THE SOUTH AND
WARM ADVECTION BRINGS WARMER AIR TO THE REGION. TEMPERATURES COULD
BE AS MUCH AS 10 DEGREES WARMER ACROSS THE AREA. THE CONCERN IS THAT
THE CURRENT SNOW COVER WILL INHIBIT THE WARMING. EXPECTING THAT
THERE WILL BE ENOUGH WIND TO MIX THE WARMER TEMPERATURES ALOFT DOWN
TO THE SURFACE. THURSDAY NIGHT THE WARM ADVECTION CONTINUES THROUGH
THE NIGHT AND LOW TEMPERATURES SHOULD BE QUITE A BIT WARMER THAN THE
PREVIOUS NIGHT.

THE NEXT SYSTEM TO AFFECT THE AREA IS TOWARD THE WEEKEND. MODELS
HAVE DIFFERING SOLUTIONS WITH THIS WAVE AND PROVIDES A CHALLENGE.
THE ECMWF KEEPS FRIDAY MAINLY DRY AS A COLD FRONT MOVES THROUGH THE
AREA AND THE UPPER WAVE MOVES QUICKLY THROUGH WITH THE MAIN ENERGY
TO THE NORTH OF THE FORECAST AREA. AFTER THE WAVE MOVES THROUGH WARM
ADVECTION TAKES PLACE AGAIN AND TEMPERATURES SHOULD WARM UP. ON THE
OTHER HAND...THE GFS CLOSES THE UPPER LOW OFF IN THE SOUTHWEST CONUS
AND BRINGS THE LOW THROUGH THE CENTRAL/SOUTHERN PLAINS SATURDAY AND
SATURDAY NIGHT...THEN IS SLOWER TO WARM THINGS UP ON SUNDAY. HAVE
TRENDED TOWARD THE ECMWF AND KEPT A DRY FORECAST FOR NOW.
