AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
935 PM CDT TUE MAY 4 2010

.DISCUSSION...
A FEW LIGHT SHOWERS HAVE HUNG ON ACROSS THE SOUTHEAST CORNER OF THE
CWA THIS EVENING WITH WEAK WAVE PUSHING THRU THE AREA AND ADJUSTED
POPS IN THE GRIDS EARLIER FOR THIS THROUGH 04Z. CLEARING EXPECTED TO
FOLLOW AS THE WAVE PUSHES EAST OF THE FORECAST AREA...WITH LITTLE
CHANGE TO GOING FORECAST LOWS IN THE UPPER 30S TO LOWER 40S. WINDS
SHOULD INCREASE AGAIN LATER TONIGHT AS ANOTHER PUSH OF WEAK COLD
ADVECTION AND PRESSURE RISES MOVE INTO THE AREA FROM THE WEST.
STRONGER WINDS ALOFT WITH THIS SURGE THAN WE SAW EARLIER TODAY...
THOUGH ANY SPEEDS PUSHING WIND ADVISORY CRITERIA EXPECTED TO HOLD
OFF UNTIL A FEW HOURS AFTER DAYBREAK. UPDATED GRIDS/PFM/ZFP HAVE
BEEN SENT.

&&

.AVIATION...
WNDS WL AGAIN BE THE MOST SIGNIFICANT AVIATION CONCERN. AFTER A
RELATIVELY QUIET NIGHT...MARRED ONLY BY PASSAGE OF SECONDARY SFC
TROUGH TOWARD EARLY MORNING ARND KHON...AND QUICKLY THRU REST OF CWA
DURING MORNING STRENGTHENING GRADIENT. CONTINUED CAA WL AGAIN BRING
A STRONGLY MIXED DAY WITH WINDS GUSTING AOA 30KTS FROM 14-15Z THRU
MOST OF AFTN HOURS. VFR CONDITIONS WL CONTINUE THROUGH THE PERIOD.
/CHAPMAN
&&

.PREV DISCUSSION...
WINDS DID NOT QUITE MAKE IT TO ADVISORY CRITERIA AND WITH ONLY A FEW
HOURS LEFT UNTIL SUNSET WHEN THE WINDS WILL DROP OFF...WILL GO AHEAD
AND DROP THE ADVISORY.. OTHERWISE...NOT MUCH LEFT OF THUNDERSTORM
CHANCES AS THE SFC COLD FRONT HAS PRESSED EAST OF THE CWA. STILL
HAVE SOME COLD AIR ALOFT WORKING INTO THE CWA SO COULD SEE A BRIEF
SHOWER OR SPRINKLES WITH THIS. DO NOT FEEL THAT COVERAGE WILL BE
ENOUGH TO WARRANT A MENTION THOUGH. WINDS SHOULD STAY A LITTLE MIXY
TONIGHT SO EVEN WITH THE COLDER AIR WORKING IN WILL AIM FOR LOWS IN
THE UPPER 30S TO AROUND 40.  /08

WEDNESDAY IS LOOKING TO BE DRY AS THE UPPER LEVEL LOW OVER THE UPPER
MIDWEST EARLY IN THE DAY PUSHES OFF INTO THE GREAT LAKES REGION.
ONLY REAL EFFECT FROM THIS SYSTEM WILL BE A FEW CLOUDS IN OUR
NORTHERN ZONES.  OTHERWISE...BELOW NORMAL TEMPERATURES WILL BE THE
RULE ONCE AGAIN WITH CAA CONTINUING ACROSS THE AREA...AND HIGHS
SHOULD TOP OUT IN THE UPPER 50S TO LOWER 60S. WITH THE CAA/STEEP LOW
LEVEL LAPSE RATES/INCREASING PRESSURE RISES/AND 850 AND 925 MB
WINDSPEEDS AROUND 30 TO 40 KTS IT WILL BE ANOTHER WINDY DAY...AND A
WIND ADVISORY MAY BE IN ORDER AT SOME POINT.

MAY SEE LIGHT SHOWERS DEVELOP IN OUR FAR WEST LATE WEDNESDAY NIGHT
WITH WAA OUT AHEAD OF A MID LEVEL WAVE LIFTING OUT OF WYOMING. WINDS
WILL DIE OFF ON WEDNESDAY NIGHT AND LOWS WILL DROP DOWN INTO THE
UPPER 30S TO LOWER 40S. WEAK WAVE CONTINUES TO TRACK ACROSS THE AREA
ON THURSDAY WITH WAA/ISENTROPIC LIFT OVERSPREADING THE CWA. BEST
CHANCE OF POPS ON THURSDAY WILL RESIDE IN OUR NORTH AND WEST WHERE
DEEPER MOISTURE COINCIDES. IT WILL BE A VERY COOL DAY WITH
CLOUDS/POSSIBLE SHOWERS AND AN EASTERLY LOW LEVEL FLOW...AND HIGHS
LOOK TO BE AROUND 50 IN OUR NORTH AND WEST TO AROUND 60 IN OUR FAR
SOUTHEAST.

RAIN CHANCES WILL PICK UP ON THURSDAY NIGHT AS THE MAIN WAVE PUSHES
OUT OF THE ROCKIES...AND HAVE HIGHEST POPS ACROSS OUR NORTH WITH A
DEVELOPING TROWAL...AND MODELS SUGGESTING THAT THE DRY SLOT MAY
SWING ACROSS OUR SOUTH VERY LATE THURSDAY NIGHT AND EARLY FRIDAY.
THERMAL PROFILES DO SUGGEST THAT A LITTLE BIT OF SNOW COULD MIX IN
WITH RAIN OVER THE WESTERN JAMES RIVER VALLEY BY VERY EARLY FRIDAY
MORNING WITH THE 850 MB 0 DEGREE ISOTHERM PUSHING THROUGH THAT AREA
BY 12Z ON FRIDAY. NOT TOO WORRIED ABOUT SNOW STICKING AT THIS POINT
WITH WARM GROUND AND SURFACE TEMPERATURES REMAINING IN THE MID 30S
OR ABOVE ON THURSDAY NIGHT. FRIDAY IS LOOKING TO BE A RAW MISERABLE
DAY WITH PRECIPITATION TAPERING OFF FROM SOUTHWEST TO NORTHEAST AND
GUSTY NORTHWEST WINDS.  HIGHS WONT MAKE IT OUT OF THE 40S IN OUR
NORTH...TO THE LOWER 50S IN OUR SOUTH.

IN THE EXTENDED...SATURDAY THROUGH MONDAY...A RELATIVELY ACTIVE AND
COOL PATTERN LOOKS TO CONTINUE ACROSS THE REGION. WITH FRIDAYS
DEPARTING SYSTEM...WE WILL GET A BRIEF REPRIEVE FROM PRECIPITATION
ON SATURDAY AS SURFACE AND UPPER LEVEL RIDGING BUILDS INTO THE
REGION. 850 MB TEMPERATURES WILL STILL BE HOVERING JUST EITHER SIDE
OF 0 DEGREES C ON SATURDAY...AND HIGHS WILL REMAIN BELOW NORMAL IN
THE MID 50S TO LOWER 60S...WITH LOWS CONTINUING IN THE MID AND UPPER
30S. BY LATE SATURDAY NIGHT INTO SUNDAY...HIGH PRESSURE BEGINS TO
PUSH OFF TO THE EAST...PUTTING US IN A RETURNING SOUTHEASTERLY
FLOW...AND COULD SEE A FEW SHOWERS IN OUR WEST SPREADING EASTWARD
WITH WAA OUT AHEAD OF LOW PRESSURE LIFTING OUT OF THE CENTRAL
ROCKIES/WESTERN HIGH PLAINS. MODELS IN PRETTY GOOD AGREEMENT WITH
THIS WAVE LIFTING OUT INTO THE PLAINS STATES FOR THE BEGINNING OF
NEXT WEEK. TEMPERATURES THROUGH THE PERIOD LOOK TO REMAIN BELOW
NORMAL IN A EAST TO SOUTHEASTERLY LOW LEVEL FLOW...WITH HIGHS AGAIN
IN THE UPPER 50S TO LOWER 60S...POSSIBLY WARMING MAINLY INTO THE 60S
BY TUESDAY. LOWS WILL BE GENERALLY IN THE LOWER TO MID 40S.  /JM
