AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
925 PM CST TUE JAN 17 2012

.DISCUSSION.../ISSUED AT 925 PM CST/
HAVE BABYSAT TEMPERATURES INTO THEIR EVENING DROP. IN GENERAL THEY
ARE ABOUT TO STALL AND GO UP THOUGH OF COURSE SOME LOCATIONS IN THE
EAST WILL COOL A BIT MORE AS THE SURFACE RIDGE EXITS. CHAMBERLAIN
WAS STILL 2 ABOVE AT 9PM UNDOUBTEDLY BECAUSE OF COLD AIR TRAPPED IN
THE VALLEY BUT THEY SHOULD WARM UP STEADILY NOW...AS SHOULD OTHER
LOCATIONS FROM WEST TO EAST. PUSHED ON WITH A STRONGER WARMUP
TONIGHT ALONG THE BUFFALO RIDGE GIVEN THE INCREASINGLY SHALLOW
NATURE OF THE INVERSION. STILL A LITTLE TRICKINESS AS SOME SHELTERED
HOLDOUTS COULD COOL OR HOLD STEADY A BIT LONGER THAN EXPECTED.
EARLIER WENT FOR A LITTLE LESS INTRUSION OF HIGH CLOUDS FROM THE
NORTHWEST AS THE NIGHT GOES ON...AND THE MID PATCH EXPECTED TO
DEVELOP AND MOVE OVER THE SOUTHEAST CORNER BY THE END OF THE NIGHT
MAY BE FURTHER SOUTHEAST OR NONEXISTENT. WINDS LOOK OK WITH WARMING
FLOW NOW SPREADING INTO AREA. / WILLIAMS

&&

.AVIATION.../FOR THE 00Z TAF ISSUANCE/
VFR CONDITIONS WILL PREVAIL FOR TONIGHT AND WEDNESDAY MORNING. AS
HIGH PRESSURE MOVES TO THE EAST...A LOW LEVEL SOUTHERLY FLOW WILL
RETURN TO THIS FORECAST AREA. THE LOW LEVEL JET WILL BECOME STRONG
IN OUR SOUTHEASTERN ZONES...WHICH WILL GIVE NON CONVECTIVE LOW LEVEL
WIND SHEAR FOR THE KSUX TAF SITE IN THE 09Z TO 15Z TIME FRAME LATE
TONIGHT AND WEDNESDAY MORNING. A STOUT 45 KNOTS IS FORECAST BY THE
NAM NOT TOO FAR OFF THE SURFACE...NEAR 1500 FEET AGL...FOR THOSE
AREAS. OTHERWISE...AN ARCTIC COLD FRONT WILL DROP RAPIDLY SOUTHWARD
ACROSS THE SIOUX FALLS FORECAST AREA WEDNESDAY AFTERNOON. AN ABRUPT
WIND SHIFT WILL OCCUR WITH GUSTY WINDS FROM THE N TO NW PROCEEDING
FROM NORTHWEST TO SOUTHEAST ACROSS THE AREA AS THE AFTERNOON
PROGRESSES. IN ADDITION TO THE WIND SHIFT...MVFR STRATOCU COULD
FOLLOW WITH THE COLD AIR ADVECTION...ESPECIALLY ALONG AND NORTH OF A
HURON SD TO SPENCER IA LINE WITH FLURRIES DURING TUESDAY AFTERNOON.
THE MVFR CEILINGS MAY ALSO MAKE IT INTO THE SIOUX FALLS TAF SITE
VERY LATE IN THE TAF PERIOD...AND THE 06Z TAFS MAY VERY WELL REFLECT
THIS.  /MJF

&&

.PREV DISCUSSION.../ISSUED AT 303 PM CST/
BIG PICTURE THIS AFTERNOON REVEALS A MORE OR LESS ZONAL CYCLONIC
FLOW OVER THE PLAINS WITH WEAK RIDGING DEVELOPING UPSTREAM JUST
DOWNSTREAM FROM THE ROCKIES. ANOTHER WAVE IS POISED JUST OFF THE
PACIFIC NORTHWEST COAST...AND OMINOUS IS THE VERY COLD AIR NOTED ON
MORNING RAOB ANALYSIS LURKING OVER CENTRAL CANADIAN PROVINCES...AND
WAVE TO RELEASE THE BULK OF COLD AIR BACK OVER CENTRAL BRITISH
COLUMBIA....JUST WAITING TO PHASE IN WITH TROUGH IN THE PACIFIC
NORTHWEST. JUST HOW COLD IS THE AIR...TEENS TO 20S BELOW ZERO EARLY
AFTERNOON. CHALLENGE IN THE SHORT TERM IS ALMOST FULLY IN THE
TEMPERATURE FORECAST.

TOUGH TO MAKE A SOLID CALL ON HOW MUCH TEMPERATURE WILL PLUNGE THIS
EVENING AS WEAK RIDGE AXIS NEAR THE I29 CORRIDOR RETREATS EASTWARD
DURING THE EVENING. LOWS ALMOST CERTAINLY WILL BE RIGHT OFF THE BAT
IN THE FAR WEST AS SOUTHERLY FLOW INCREASES...EVEN FOR LOCATIONS
WITH DEEPER SNOWCOVER FROM K9V9 AREA TO KHON. SNOWFALL FROM LAST
NIGHTS EVENT DROPPED OFF PRECIPITOUSLY TO THE SOUTHEAST...SO NOT AS
GOOD/SOLID A SNOWCOVER TO PARTICIPATE IN EVENING RADIATIVE FEST.
DID DROP TEMPERATURES BY SEVERAL DEGREES...ESPECIALLY EAST. STRONGLY
NON DIURNAL TEMPERATURES OVERNIGHT AS SOUTHERLY GRADIENT INCREASES.

CLIPPER WAVE WILL TRACK TO THE NORTH OF THE AREA ON WEDNESDAY...AND
THIS WILL OPEN THE DOOR FOR A BRIEF PERIOD OF MILDER AIR TO SPREAD
ACROSS THE AREA. ISOTHERMAL TO SHALLOW MIXING WOULD ALLOW FOR 20S
EVEN IN DEEPER SNOWCOVER TO THE NORTH...AND LIKELY A DEEPER MIXING
THROUGH THE SOUTH...WHERE MID TO UPPER 30S LIKELY. HOWEVER...THIS
MILD AIR WILL COME TO AN END WITH STRONG COLD FRONT BLASTING THROUGH
THE AREA DURING THE AFTERNOON. TEMPERATURES BY LATER TOMORROW SHOULD
BE EQUALLY AS NON DIURNAL IF NOT MORE...AS ABOUT A 8-10C FALL IN 925
HPA TEMPERATURES OCCURS THE LAST 3 HOURS BEHIND THE FRONT.

RIGHT NOW...APPEARS WINDS MAY ACTUALLY GET NEAR LOWER END ADVISORY
FOR A VERY BRIEF TIME...AND GIVEN THE DEEPER SNOWCOVER TO THE
NORTH...MAY GET A BIT OF BLOWING SNOW GOING IN THE AFTERNOON. ALSO
ADDED A SMALL CHANCE FOR MEASURABLE SNOW ACROSS THE FAR NORTHEAST
CLOSER TO THE TRACK OF THE DIV Q AREA/PV ADVECTION. ELSEWHERE BEHIND
THE BOUNDARY...A FEW LATE DAY FLURRIES COULD ALSO ACCOMPANY THE
SHARP COOLING AS TEMPERATURES FALL WELL INTO THE DENDRITIC GROWTH
ZONE.   /CHAPMAN

THURSDAY LOOKING DOWNRIGHT COLD WITH SOMEWHAT BREEZY CONDITIONS IN
THE EAST DURING THE MORNING. IF THE FORECAST WINDS AND TEMPERATURES
VERIFY WE MAY NEED A WIND CHILL ADVISORY LATE WEDNESDAY NIGHT INTO
THURSDAY MORNING FOR THE NORTHEAST THIRD OF THE CWA. OTHER THAN A
FEW FLURRIES OR SOME VERY LIGHT SNOW WEDNESDAY NIGHT JUST EXPECTING
A COLD PERIOD. TEMPERATURES ON THURSDAY MORNING LIKELY IN THE TEENS
BELOW ZERO IN THE NORTHERN CWA WITH NEAR ZERO IN THE FAR SOUTH WHERE
CLOUDS MAY HAMPER ANY TRUE RADIATIONAL DROP OFF. RECOVERY ON
THURSDAY WILL BE SLOW AND LIKELY ONLY ABOUT 5 TO 10 DEGREES WARMER
THAN MORNING LOWS.

THURSDAY NIGHT INTO FRIDAY CONTINUES TO LOOK LIKE OUR NEXT BEST
POTENTIAL SNOW EVENT. LOW PRESSURE ALOFT WILL MOVE THROUGH THE
CENTRAL ROCKIES ONTO THE PLAINS THURSDAY NIGHT WITH STRONG SOUTHERLY
FLOW DEVELOPING AHEAD. THIS IS ALSO AIDED BY AN EXITING NORTHERN
STREAM JET LIFTING NORTHEAST. WITH NO MAJOR LOW TO MID LEVEL DRY AIR
THIS SYSTEM WILL HAVE THE POTENTIAL TO BE MORE EFFICIENT THAN THIS
MORNINGS. THIS ALSO SUGGESTS THAT THE SNOW WILL BE MORE WIDESPREAD
AND LESS FOCUSED ALONG A MID LEVEL FRONT SO HAVE INCREASED POPS
ACROSS MAINLY THE SOUTHERN CWA WHERE THE BETTER ISENTROPIC ASCENT
EXISTS AROUND 290K TO 295K SURFACE...WHICH IS ABOUT FROM 825MB TO
675MB. WILL NEED TO WATCH THE EVOLUTION OF THIS SYSTEM OVER THE NEXT
DAY AS IT COULD BECOME AN ADVISORY TYPE SYSTEM. HOWEVER...THE CAVEAT
WILL BE JUST HOW FAR SOUTH THE VERY COLD CANADIAN AIR DRIVES SOUTH
AND THE POTENTIAL FOR THIS WAVE TO COME OUT FARTHER SOUTH AND
WEST...BRINGING MORE CLEARING TO THE NORTH AND A BETTER CHANCE FOR
TEMPERATURES TO PLUMMET THURSDAY NIGHT.

FRIDAY WILL STILL BE LOCKED INTO THE COLD AIR SO WENT ON THE COLD
SIDE OF GUIDANCE WITH HIGHS MAINLY IN THE TEENS. IF THE SYSTEM COMES
OUT AS EXPECTED SHOULD BE A LITTLE MORE MEASURABLE SNOW ON FRIDAY
MORNING IN THE EAST BEFORE COLDER DRIER AIR COLLAPSES IN BEHIND.

IN THE LATTER PERIODS(SAT/TUE)...THE POTENTIAL IS THERE FOR A WARM
WEEKEND...HOWEVER NOW THAT WE HAVE A MORE WIDESPREAD LIGHT SNOW
COVER...WITH MORE TO POTENTIALLY COME ON THURSDAY NIGHT...WILL HAVE
TO SEVERELY TEMPER BACK THE POTENTIAL. THE OVERALL PATTERN IS FOR
CONTINUED STRONG WESTERLY FLOW ALOFT WITH THE JET STREAM MUCH CLOSER
TO AND A LITTLE SOUTH OF THE AREA...VS. NORTH OF THE AREA LIKE THE
PREVIOUS MONTH OR TWO. THIS ALSO INDICATES ANY WARM UPS WILL LIKELY
BE MORE BRIEF...A COUPLE OF DAYS. WILL GO ABOVE CLIMATOLOGY DURING
THIS PERIOD THOUGH AS COLD AIR NOT INDICATED BY ANY OF THE MODELS.
CHANCES FOR PRECIPITATION TOO LOW AND WILL HAVE NO POPS. /08
