AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
1112 AM CST THU DEC 18 2008

.DISCUSSION...
POURED OVER THE LATEST 12Z DATA FM THE GEM/GFS AND NAM. SNDGS FM
BOTH THE NAM AND GFS ARE QUITE COLD LATE THIS AFTERNOON AND EARLY
EVENING IN OUR FAR SRN FA...ESP AFTER WETBULBING DOWNWARD TOWARD
SATURATION GIVEN THE INITIALLY DRY LOW LEVELS. THEREFORE WITH THE
TREND OF LOW LEVEL DRY AIR...DECIDED TO START OUR WX AND POPS AT A
SLIGHTLY DELAYED 20Z ALONG THE MO RIVER VALLEY...WITH RAPID
SATUATION FM SW TO NE AFTER THAT. THERE COULD BE A BRIEF CHC FOR
SLEET EARLY IN THE EVENING DURING THE MID OR LATE AFTERNOON HRS FOR
THE SIOUX CITY AREA...BUT AFTERWORDS...THEY SHOULD RAPIDLY CHANGE TO
SNOW DUE TO EVAPORATIVE COOLING ALOFT. THE GFS LOOKS TO BE TOO
BULLISH ON ITS QPF TOO FAR TO THE NW GIVEN ITS BEST DYNAMICS...WHICH
ARE ACTUALLY WELL PLACED WITH THE NAM. STRONG QG FORCING SKIRTS
ALONG THE SRN FA TONIGHT...THE STRONGEST THIS EVENING. THIS IS
COUPLED WITH THE SE QUAD OF OUR FA WELL PLACED IN THE LEFT EXIT
REGION OF A JET STREAK...NEARLY COUPLED WITH THE RR QUAD OF ANOTHER
JET STREAK IN S CENTRAL MN. MID LVL PV IS STRONG...ESP IN NW IA...
AND BOTH THE NAM AND GFS SHOW PRETTY STRONG INSTABILITY ABV THE
STRONGEST FRONTOGENESIS AROUND THE STORM LAKE IA AREA THIS EVENING.
CONCERNING THE INSTABILITY...AM WORRIED THAT A MESOSCALE BAND OF MDT
TO HEAVY SNOW MAY GET GOING THIS EVENING AND ERN WOODBURY...IDA AND
BUENA VISTA COUNTIES WHERE A 5 TO 8 INCHES OF SNOW COULD FALL
TONIGHT. THEREFORE UPGRADED THOSE 3 COUNTIES TO A WARNING. REMEMBER
THAT SIOUX CITY ITSELF THOUGH WL PROBABLY STAY IN AN ADVY TYPE SNOW.
EXPANDED THE ADVY WWD A BIT TO INCLUDE DIXON NEB AND UNION SD...AND
FORSTALLED ALL HEADLINE TIMING TO START AT 00Z THIS EVENING DUE TO
THE AFOREMENTIONED LOW LEVEL DRY AIR. WL HAVE A NEW TOTAL SNOWFALL
GRID OUT CLOSER TO NOON TO REFLECT THIS AFTER MY TAFS GO OUT.
OTHERWISE...OUR INCREASE IN CLOUDS LOOK GOOD FM SW TO NE TODAY AS
WELL AS MODERATING TEMPS AND INCREASING WINDS FM THE EAST THIS
AFTERNOON.

.AVIATION...
INITIAL SATURATION WL COMMENCE ALFT THIS AFTN...WITH CIGS GRADUALLY
LOWERING THRU THE AFTN. EXPECT PCPN TO DVLP TOWARD KSUX BY MID TO
LATE AFTERNOON...AND KFSD PERHAPS THE LAST TO SEE DEVELOPMENT IN THE
RELATIVELY DEEPER LOW LVL DRY AIR FED BY ELY FLOW. SATURATION FROM
ALFT WL OCCUR QUITE SUDDENLY LATE AFTN/ERLY EVNG...WITH A CERTAINTY
FOR A SHORT PERIOD OF IFR VSBYS AND MAINLY MVFR CIGS...BRIEFLY IFR
CIGS AS PCPN BANDS WORK THROUGH THE AREA 00Z-09Z.

SNOW COVER INVERSION WREAKING HAVOC ON LOW TEMPS THIS MRNG WITH
TEMPS BOTTOMING OUT BELOW ZERO IN RANDOM DECOUPLED LOCATIONS.
THIS INVERSION SHOULD BREAK UP SOME THIS AFTN AS SELY FLOW BRINGS
IN NOT AS COLD AND MORE MOIST AIR FROM THE SOUTH. MOST RECENT
MODELS BACK TO THE MORE GUNGHO SCENARIO BRINGING GOOD ISENTROPIC
LIFT AND BANDS OF SNOW INTO SRN CWA THIS AFTN AND OVER ENTIRE CWA
TNGT. PROBLEM IS THE BANDS WILL FOCUS AT DIFFERENT LEVELS...WITH
WITH THE 850 BOUNDARY MORE THE FOCUS IN NW IA AND THE 700MB BOUNDARY
THE FOCUS FM SERN SD TO SWRN MN BY TNGT. IT APPEARS THE BEST
MOISTURE TRANSPORT AND LIFT STILL EXPCD EAST OF I29 WHERE WILL
KEEP THE ADVY...BUT 6 INCHES STILL NOT OUT OF THE QUESTION WITH THE
CONVECTIVE NATURE ALOFT. HOWEVER...WILL HAVE TO WORRY ABOUT SOME
3 TO 5 INCHERS ALSO TO THE NORTH AND WEST IF MID LVL BOUNDARY CAN
GET SOME MOISTURE INFLOW FROM THE SOUTH. SYSTEM MOVES OUT PRETTY
FAST TO THE ENE LATE TNGT...AND GUID TEMPS WILL CONTINUE ON THE
WARM SIDE THRU FRI WITH WEAK NELY FLOW.

ATTN TURNS TO THE MAIN DVLPG UPR TROF CRASHING EWD OVER THE CWA THIS
WEEKEND. THIS SYSTEM WILL BE VERY EFFICIENT IN SQUEEZING OUT SNOW
DUE TO NEG TILT AND COLD AIR ALOFT...WITH THE MAIN DYNAMICS ALG AND
NORTH OF I90 FM LATE FRI NGT THRU SAT NGT. HIT THE POPS AND SNOWFALL
PRETTY HARD IN THIS AREA...AND THEN VERY STRONG NWLY WINDS BRING IN
MUCH COLDER AIR FROM THE WEST. SHOULD BE A SERIOUS SITUATION DVLPG
WITH BLOWING SNOW AND WIND CHILL WARNING WIND CHILLS. NEXT SHIFT
WILL HAVE TO CONSIDER WINTER STORM OR BLIZZARD WATCH...AFTER THE
FIRST SYSTEM STARTS TO MOVE OUT.
