AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
905 PM CDT WED OCT 5 2005

.DISCUSSION...
GUSTY WINDS AND NEAR FREEZING TEMPERATURE THE BIGGEST FOCUS FOR
TONIGHT. FORECAST SOUNDINGS INDICATE LOWER ATMOSPHERE WILL REMAIN
PRETTY WELL MIXED THROUGH THE NIGHT. GENERALLY EXPECT SUSTAINED
WINDS OF 20 TO 25 MPH THROUGH THE OVERNIGHT...WITH GUSTS AS HIGH AS
35 MPH YET THIS EVENING. A LITTLE WORRIED THAT WE COULD SEE A
SECONDARY SURGE OF SOMEWHAT HIGHER GUSTS WITH A SECOND PUSH OF COLD
ADVECTION AROUND 06Z...BUT STILL ONLY MARGINAL ON REACHING ADVISORY
CRITERIA...SO HAVE LET WIND ADVISORY EXPIRE AT 00Z AS SCHEDULED.

REMAINDER OF FORECAST LOOKING TO BE IN PRETTY GOOD SHAPE. A FEW
BREAKS HAVE DEVELOPED IN MORE CELLULAR CLOUD COVER THROUGH THE JAMES
VALLEY AND INTO NORTHWEST IOWA EARLY THIS EVENING...BUT MORE SOLID
AREA OF CLOUDS PUSHING SOUTHEAST AND EXPECT THE MOST OF SD AND MN
COUNTIES TO FILL BACK IN AGAIN LATER TONIGHT. CONTEMPLATED EXPANDING
FREEZE WARNING NORTH INTO KHON AREA WITH COLDER 850MB TEMPERATURES
EXPECTED IN THAT AREA BY MORNING...AND COULD BE CLOSE IN SOME AREAS
OF THE MIDDLE JAMES VALLEY...BUT DO NOT EXPECT FREEZING TEMPS TO BE
WIDESPREAD ENOUGH TO WARRANT EXPANDING WARNING AT THIS TIME. UPDATED
GRIDS AND ZFP SENT EARLIER WITH EXPIRATION OF WIND ADVISORY.

&&

.PREV DISCUSSION...
AFTER ALL THE ACTIVE WEATHER OF THE PAST FEW DAYS A QUIETER PATTERN
LOOKS TO SET UP INTO THE WEEKEND.  AS THE TIGHTLY WOUND SURFACE LOW
CURRENTLY SITUATED OVER MINNESOTA MOVES EASTWARD INTO THE GREAT
LAKES...A LESSENING PRESSURE GRADIENT WILL ALLOW FOR DECREASING
WINDS THROUGH THE DAY ON THURSDAY.  WITH WINDS BECOMING LIGHT BY
THURSDAY NIGHT AND SKIES CLEARING AS SURFACE HIGH PRESSURE BECOMES
CENTERED OVER THE NORTHERN PLAINS...MAXIMUM RADIATIONAL COOLING WILL
OCCUR AND TEMPERATURES WILL BOTTOM OUT OVER THE AREA BY FRIDAY
MORNING.  WITH THE ABOVE SCENARIO IN PLACE AND 850 TEMPERATURES IN
THE RANGE OF 0 TO -6 OVER THE CWA...I WENT GENERALLY BELOW GUIDANCE
AND FORECASTED LOWS WELL DOWN INTO THE 20S.  CONTINUED DRY THROUGH
THE WEEKEND...AND AS A SOUTHERLY FLOW RETURNS TO THE REGION THERE
WILL BE A GRADUAL WARMING TREND THROUGH THE PERIOD WITH TEMPERATURES
APPROACHING NEAR NORMAL LEVELS BY SATURDAY AND SUNDAY.  MODELS
REMAIN IN PRETTY GOOD AGREEMENT ON BRINGING A DEEP TROUGH INTO THE
WESTERN U.S. BY THE BEGINNING OF NEXT...THEN PUSHING IT INTO THE
CENTRAL PART OF THE COUNTRY BY MIDWEEK.  OF COURSE THERE ARE THE
USUAL DISCREPANCIES IN TIMING...WITH THE CANADIAN MODEL BEING THE
OUTLIER BY BRINGING THE TROUGH OVER OUR REGION A DAY EARLIER THAN
THE REST.  IN ANY EVENT...LOOKS LIKE PRECIPITATION WILL BE A PRETTY
GOOD BET SOMETIME FOR THE PERIOD OF TUESDAY TO WEDNESDAY...AND I
HAVE HINTED AT THIS SOLUTION IN THE GRIDS BY KEEPING IN CHANCE POPS
FOR THOSE DAYS.

&&

.AVIATION...
AREAS OF MVFR CIGS AROUND 2500 FT ARE EXPECTED TO SLOWLY EXPAND
SOUTHEAST ACROSS TAF SITES TONIGHT...MOST LIKELY IN KHON AND KFSD
AREAS...WITH CONDITIONS IMPROVING AFTER 16Z. GUSTY WEST TO NORTHWEST
WINDS WILL CONTINUE THRU MUCH OF THE DAY THURSDAY ALTHO SPEED ARE
EXPECTED TO DIMINISH SOME AFTER 19Z AS HIGH PRESSURE BEGINS TO PUSH
INTO THE AREA FROM THE WEST.

SOUTHWEST MINNESOTA...NORTHWEST IOWA...AND NORTHEAST NEBRASKA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS...
ISOLATED THUNDERSTORMS WILL CONTINUE THROUGH MID AFTERNOON IN
NORTHWEST IOWA AND COULD PRODUCE DIME SIZE HAIL.  THUNDERSTORMS
ARE THEN EXPECTED TO DEVELOP LATE THIS AFTERNOON IN EASTERN
NEBRASKA AND SPREAD INTO NORTHWEST IOWA AND FAR SOUTHEAST SOUTH
DAKOTA BY THE EVENING.	THESE STORMS WILL HAVE THE POTENTIAL OF
PRODUCING HAIL UP TO HALF DOLLAR SIZE.	IN ADDITION...AN ISOLATED

LIKELY...ESPECIALLY NEAR AND SOUTHWEST OF A CHAMBERLAIN TO
PICKSTOWN LINE.

EXCESSIVE TEMPERATURES...
WHILE WINDS AND CLOUDS COVER SHOULD KEEP TEMPERATURES FROM
FALLING RAPIDLY TONIGHT...SOME AREAS MAY SEE MARGINAL FREEZING
TEMPERATURES...MAINLY IN THE CHAMBERLAIN TO GREGORY AREA.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

MUCH COOLER AIR WILL PERSIST ACROSS THE AREA THURSDAY INTO
