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

.DISCUSSION...
THO THERE MAY BE A LTL DCSR IN WNDS AND CLDS ERY THIS EVE...BOTH
SHUD HOLD UP PRETTY WELL THRU TNGT. THE WND DCRS WILL BE CRITICAL
ENUF ON A MARGINAL SITN TO END CURNT WND ADVY AT 7 PM/00Z INSTEAD OF
CURNT ENDG TIME OF 10 PM/03Z. 9V9 AND HON HAVE BEEN RUNNING JUST
BARELY AT ADVY LEVELS...AND THIS HR YKN ALSO MADE IT. MHE NOT QUITE
THERE BUT THERE CUD YET BE SOME INCRS NEXT CPL HRS.

WNDS AND CLDS SHUD HOLD UP WELL ENUF TO PREVENT FREEZE WARNG
CRITERIA MOS OF FCTS AREA TNGT WITH MAYBE A FEW AREAS BARELY
TOUCHING THE FRZG MARK. IN FACT AFTER A SLGT ERY EVE DCRS IN CLDS
PSBL SRN PART OF FCST AREA...CLDS SHUD SOLIDIFY. HWVR WITH A LTL LWR
DEWPTS AND PRBLY SLGTLY BETTER DECOUPLING OF WNDS HAVE ELECTED TO GO
WITH FREEZE WARNNING SWRN CRNR OF FCST AREA. NEEDLESS TO SAY THAT
WITHOUT A FREEZE...FROST IS A NON ISSUE WITH THE CLDS AND WND.

WITH A LTL BETTER MOISTR PSBLY GETTING IN ON NWRLY FLOW OF COLD
AIR...WILL KEEP THE SLGTEST MENTN OF PCPN IN THE FAR N WITH ISOLD
SPRNKLS/FLRYS TNGT.

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.
