1040 AM CST TUE DEC 13 2005

.DISCUSSION...
ERYR FCST THRU THE DAYLIGHT HRS WAS LOOKING PRETTY GOOD. UPDATED
MAINLY TO KICK UP WNDS WHICH WERE NOT HI ENUF. OTRW TEMPS AND INCRG
CLDS LOOK OK...AS DOES THE INITIAL SLGT CHC SHWRS FAR SE LATE AFTN.
PCPN CUD BE DVLPG OVER WRN PART OF FCST AREA TNGT SLOWER THAN WHAT
WE HAVE...BUT AS WE HAVE MAINLY JUST A CHC OF PCPN IT IS BEST TO
LEAVE ALONE AT THIS TIME...AT LEAST SOME SCT LGT PCPN CUD DVLP.

&&
.AVIATION...
LINGRNG MVFR VSBYS FAR ERN PART OF FCST AREA IN MN AND IA SHUD CONT
TO IMPRV. LAST KNOWN LINGRNG IFR CIG AND VSBY AT MJQ JUST IMPRVD TO
4 MI WITH NO CIG. OTRW NO AVIATION PRBLMS EXPCT THRU 23Z. MAY HAVE
TO WATCH FOR LO CLD REDVLPMNT AHD OF PCPN THIS EVE...THEN COND WILL
TEND TO LWR AS PCPN MOVES IN DURG TNGT.

&&
.PREV DISCUSSION...
IN THE IMMEDIATE SHORT TERM...MAY TWEAK THE DENSE FOG ADVY A BIT
EARLY THIS MORNING BY SHAVING OFF A ROW OF COUNTIES OFF OF THE W AND
SW EDGE. CURRENT 11 TO 3.9 MICRON IR SHOWS THE FOG FM THE
KINGSBURY/BEADLE COUNTY BORDER...EXTENDING SEWD TO NRN
MINNEHAHA...AND TO BETWEEN KSPW AND KSLB. ALL SFC WINDS HAVE COME
AROUND TO THE SE...AND THE FOG AREA HAS BEEN NEARLY STATIONARY
TONIGHT...XCPT THAT IT HAS ERODED IN LINCOLN AND TURNER COUNTIES PER
PHONE CALLS. BETWEEN 12Z AND 15Z...SFC GRADIENT BECOMES RATHER
STRONG AND ALTHOUGH WE ARE NOT WELL MIXED TODAY...IT SHOULD BE ENUF
TO ALLEVIATE THE DENSE FOG SITUATION BY MID MORNING THRU MIXING
ALTHOUGH THE STRATUS WL BE HARDER TO CLEAR OUT. DUE TO THIS
WIND...IT MAY BE UNLIKELY THAT FOG WL DEVELOP ANY FURTHER S OR SW
THAN WHERE IT CURRENTLY IS.

PRIMARY FOCUS IN THE LATER SHORT TERM IS AN UPPER LEVEL TROUGH
FORECASTED TO PUSH INTO THE REGION LATER TODAY THROUGH TOMORROW.
LEADING WAVE...AS EVIDENCED BY WATER VAPOR IMAGE...IS CURRENTLY
MOVING OUT OF THE CENTRAL ROCKIES AND WILL BEGIN TO EFFECT OUR CWA
BY THIS EVENING.  OUT AHEAD OF THIS SYSTEM...WINDS WILL PICK UP OUT
OF THE SOUTHEAST THROUGH THE DAY...WITH GUSTS OF 20 TO 25 KTS OVER
SOME AREAS BY AFTERNOON.  PRECIPITATION IS EXPECTED TO BEGIN IN THE
SOUTHERN PORTIONS OF THE FA AROUND 00Z WHERE BEST MID AND LOWER
LEVEL FRONTOGENESIS WILL BE LOCATED...THEN SPREAD NORTH AND EAST
THROUGH THE NIGHT TIME HOURS.  PRECIP TYPE WILL BE TRICKY...WITH
MODEL SOUNDINGS AND BUFKIT SOUNDINGS INDICATING THAT PRECIPITATION
WILL INITIALLY BE IN THE FORM OF RAIN...THOUGH QUICKLY TRANSITIONING
TO A BRIEF PERIOD OF FREEZING RAIN IN THE WESTERN PORTIONS OF THE
CWA AS SURFACE TEMPERATURES FALL BELOW FREEZING...THEN TO SNOW OVER
THIS AREA BY 03Z AS THE COLUMN BECOMES SATURATED AND COOLS ALOFT.
THIS PRECIPITATION TRANSITION WILL MOVE FROM WEST TO EAST THROUGH
THE NIGHT TIME HOURS...WITH MAINLY ALL SNOW IN THE FSD AREA BY
06Z...09Z IN SIOUX CITY...AND NOT UNTIL AFTER DAYBREAK ON WEDNESDAY
IN THE FAR SOUTHEASTERN PORTIONS OF THE CWA.  DECIDED NOT TO GO WITH
A WINTER WEATHER ADVISORY AT THIS POINT...SINCE THE EVENT WILL NOT
BECOME WIDESPREAD UNTIL LATER TONIGHT...AND THE BIT OF UNCERTAINTY
IN TIMING THAT ALWAYS EXISTS WITH A MIXED PRECIPITATION EVENT...BUT
LATER SHIFTS MAY WANT TO CONSIDER AN ADVISORY AS THE EVENT DRAWS
CLOSER.

SECONDARY WAVE CURRENTLY OVER NORTHERN ROCKIES WILL THEN MOVE INTO
THE REGION BY 12Z ON WEDNESDAY...KEEPING SNOW GOING THROUGH THE
DAY.  BEST MID AND LOWER LEVEL FORCING WILL BE OVER EASTERN
ZONES...AND KEPT POPS HIGHEST OVER THIS AREA THROUGH THE DAY.
BLOWING SNOW WILL BE LIKELY WITH WINDS GUSTING OUT OF THE NORTHWEST
IN EXCESS OF 20 KTS.  WRAP AROUND MOISTURE BEHIND THE SYSTEM WILL
KEEP A CHANCE OF SNOW IN THE FORECAST INTO THURSDAY.  WITH THE UPPER
LEVEL LOW AND SURFACE LOW MOVING ONLY VERY SLOWLY INTO THE WESTERN
GREAT LAKES BY FRIDAY...DRIVING ANOTHER WEAK WAVE THROUGH THE
AREA...KEPT SOME SMALL CHANCE POPS OVER THE FA FOR THAT DAY.  WITH
ALL THE SHORT TERM ISSUES TO DEAL WITH...DID NOT MAKE ANY CHANGES TO
THE EXTENDED.

.AVIATION...
SEE ABOVE DISCUSSION...WIDESPREAD LIFR CONDS THRU MID
MORNING IN THE DENSE FOG ADVY AREA.
