AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
445 AM CDT MON MAR 23 2009

.DISCUSSION...
ACTIVE FORECAST FOR NEXT FEW DAYS AS STRONG CYCLONE IMPACTS THE
AREA. CURRENTLY...THUNDERSTORMS DEVELOPING IN WARM SECTOR.  NOT MUCH
OF A CHANGE IN NELIGH PROFILER OVER THE PAST SEVERAL
HOURS...SUGGESTING THUNDERSTORMS ARE PRIMARILY THERMODYNAMICALLY
DRIVEN.  HEIGHT OF 50 DBZ CORE HAS APPROACHED 23-24K FEET AGL IN
SOME OF STRONGER STORMS...BUT HAS NOT BEEN ABLE TO SURGE ANY HIGHER
TO LEND CONFIDENCE IN ISSUING A WARNING.

FAIRLY DYNAMIC SET UP TODAY WITH DEEPENING SURFACE LOW OVER WESTERN
NEBRASKA. GRADIENT FAIRLY TIGHT LENDING TO STRONG SOUTHEAST FLOW
ACROSS AREA. CLOUD COVER QUITE TRICKY TODAY...BUT AS LOW LEVEL
MOISTURE INCREASES EXPECT STRATUS DECK TO EXPAND AND SHROUD CWA.
WINDS OVERNIGHT HAVE DROPPED OFF SLIGHTLY...BUT STILL CLOSE TO WIND
ADVISORY CRITERIA ACROSS SOUTHWEST MINNESOTA ESPECIALLY WITH
DOWNDRAFTS FROM RESIDUAL SHOWERS ENHANCING MIXING SOME. BUFKIT
MOMENTUM TRANSFER ONLY A FEW KNOTS SHY OF WIND ADVISORY CRITERIA
ACROSS PORTIONS OF NORTHWEST IOWA...AND ELECTED TO ISSUE A SMALL
ADVISORY THROUGHOUT THE DAY TODAY.  AM MOST CONCERNED ABOUT WINDS
DOWN NEAR THE KSUX AREA THIS AFTERNOON AS MODELS PORTEND DRY SLOT
SURGING NORTHWARD POTENTIALLY WORKING INTO SOUTHERN EDGE OF FORECAST
AREA. IF THIS OCCURS...ENHANCED MIXING WILL LIKELY LEAD TO LOW END
WIND ADVISORY CONDITIONS. DRY SLOT APPEARS TO WORK TOWARDS THE KYKN
AREA LATE THIS AFTERNOON.  MU CAPE VALUES RISE TO AROUND 500
J/KG...AND EXPECT CONVECTIVE INITIATION TO BE NEAR HIGHWAY 81 ACROSS
NEBRASKA BUT POTENTIALLY AS FAR NORTH AS YANKTON. EXPECT REMNANTS OF
STORMS TO WORK INTO EASTERN PORTIONS OF FORECAST AREA TONIGHT. GIVEN
SHEAR PROFILES SUGGESTING STRONG SPEED SHEAR AND MODEST DIRECTIONAL
SHEAR...AGREE WITH SPC THE PRIMARY SEVERE THREAT WILL BE HAIL AND
WIND THOUGH AN ISOLATED TORNADO EARLY IN THE STORMS LIFE CYCLE CAN
NOT BE RULED OUT. COULD ALSO SEE SOME ELEVATED STORMS DEVELOP ACROSS
PORTIONS OF SOUTHWEST MINNESOTA THIS EVENING AS SWATH OF INSTABILITY
LIFTS TO THE NORTHEAST.

COLD FRONT CRASHES INTO WESTERN PORTIONS OF FORECAST AREA THIS
EVENING AND SWEEPS ACROSS THE AREA OVERNIGHT. TROWAL SETS MAINLY
ALONG AND WEST OF THE JAMES RIVER VALLEY TONIGHT AND AS ATMOSPHERE
COOLS COULD SEE PRECIPITATION MIX WITH AND CHANGE OVER TO SNOW
OVERNIGHT. BEST CHANCES FOR ACCUMULATION APPEAR TO BE FROM K9V9 DOWN
INTO GREGORY COUNTY. PRECIPITATION WILL LIKELY MIX WITH AND
POTENTIALLY CHANGE BACK OVER TO RAIN ON TUESDAY BEFORE THE WRAP
AROUND PRECIP LIFTS OFF TO THE NORTHEAST. WITH ACCUMULATION OF
AROUND ONE INCH OF SNOW NEAR THE K9V9 AREA...OPTED NOT TO ISSUE A
WINTER WEATHER ADVISORY.

PRECIPITATION LIFTS TO THE NNE TUESDAY NIGHT CREATING THE POTENTIAL
FOR A DUSTING OF SNOW ACROSS THE NORTHERN EDGE OF CWA.  WINDS WILL
FINALLY BEGIN TO SETTLE DOWN ON WEDNESDAY AS SYSTEM LIFTS INTO THE
GREAT LAKES REGION.  DID NOT ALTER FORECAST BEYOND WEDNESDAY DUE TO
ACTIVE WEATHER IN THE SHORT TERM.

WILL HAVE TO KEEP AN EYE ON THE NEXT SYSTEM WHICH BEGINS TO DIVE
INTO THE INTERMOUNTAIN WEST ON WEDNESDAY AND MOVES INTO THE NORTHERN
PLAINS LATE THIS WEEK INTO THE WEEKEND.  THIS SYSTEM COULD BRING THE
POTENTIAL FOR ANOTHER SIGNIFICANT SNOW EVENT ACROSS THE NORTHERN
PLAINS ON SATURDAY.

&&

.AVIATION...
A DEEPENING LOW PRESSURE OVER NEBRASKA WILL KEEP STRONG SOUTHEAST
WINDS IN PLACE THROUGH THE DAY WITH SUSTAINED WINDS AROUND 25 MPH
AND GUSTS AROUND 35 MPH...ESPECIALLY FOR FSD AND SUX. MAINLY MVFR
CEILINGS ARE EXPECTED...ALTHOUGH SOME IFR CEILINGS WILL BE LIKELY AT
TIMES THROUGHOUT THE MORNING. SCATTERED THUNDERSTORMS AROUND FSD AND
SUX WILL BE A THREAT EARLY THIS MORNING...AND AGAIN AFTER ABOUT 23Z.

&&
.FSD WATCHES/WARNINGS/ADVISORIES...
