AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
915 PM CDT MON MAY 3 2010

.DISCUSSION...
WINDS HAVE DIMINSIHED WITH SUNSET AS EXPECTED THIS EVENING...AND
LAST OF SPRINKLES/LIGHT SHOWERS JUST EXITING THE SOUTHEAST CORNER OF
THE CWA. BATCH OF MID CLOUDS POISED TO OUR NORTHWEST APPEARS TO BE
DIMINSIHING AS WELL...AS IT WORKS INTO THE SOMEWHAT DRIER AIR IN
PLACE ACROSS OUR CWA. THUS CLEAR TO PARTLY CLOUDY SKIES EXPECTED
HERE THROUGHOUT THE NIGHT. TEMPERATURES FOR TONIGHT LOOK PRETTY GOOD
AND ONLY A COUPLE OF MINOR ADJUSTMENTS IN SOME VALLEY AREAS WHERE
COME POOLING OF COOLER AIR IS POSSIBLE BEFORE SOUTHERLY WINDS PICKUP
A LITTLE MORE TO MIX THINGS OUT LATER TONIGHT.

AS MENTIONED IN PREVIOUS DISCUSSION...BIGGEST CHALLENGE FOR TUESDAY
IS HOW STRONG POST FRONTAL WINDS WILL BECOME. STRONG COLD ADVECTION
AND SURFACE PRESSURE RISES PUSH INTO WESTERN CWA BY 15Z...THOUGH
BOTH WEAKENING BY 15Z FROM WHAT IS SEEN IN WESTERN AND CENTRAL PARTS
OF THE STATE AT 12Z AND EARLIER. WOULD NOT BE SURPRISED TO SEE 1-2HR
PERIOD OF NEAR ADVISORY WINDS WEST OF THE JAMES RIVER MID-LATE
MORNING...BUT WITH WEAKENING CAA/PRESSURE RISES AND WEAK SURFACE
RIDGING PUSHING INTO MISSOURI VALLEY BY MID-LATE AFTERNOON...04/00Z
NAM SEEMS TO HAVE AS MANY FACTORS POINTING AGAINST AS AN ADVISORY AS
IT DOES TOWARD...SO WILL NOT ISSUE ANY HEADLINES AT THIS TIME AND
INSTEAD LET THE MIDNIGHT SHIFT EXAMINE UPSTREAM CONDITIONS AND
ADDITIONAL MODEL DATA.

UPDATED GRIDS/PFM HAVE BEEN SENT AND WILL HAVE UPDATED ZFP OUT
SHORTLY.   /JH

&&

.AVIATION...
LARGEST AVIATION CONCERN IS WITH WINDS THAT DEVELOP IN THE POST
FRONTAL ENVIRONMENT ON TUESDAY.  LIKELY THERE WILL BE A 1-2H SURGE
IN WINDS FOLLOWING FROPA THRU THE CWA ACCOMPANIED BY CAA/4-5MB/3H
PRESSURE RISES...WHICH APPEAR TO WEAKEN MOVING EASTWARD THRU THE
CWA. THIS SUGGESTS THE STRONGEST WNDS LKLY THRU WRN MO VLY TOWARD
JAMES VALLEY DURING MID MORNING HOURS...THEN HAVING TO WAIT UNTIL
MOST EXTREME MIXING BRINGS WINDS BACK UP DURING THE AFTERNOON HOURS.
FARTHER EWRD TOWARD KFSD/KSUX AREA...WL SEE FIRST INCREASE IN WNDS
ARND AND SHORTLY AFT 18Z...WHICH SHUD STILL BE FAIRLY SIGNIFICANT
DESPITE WKNG OF THE ISALLOBARIC PULSE...SINCE WL HAVE TIME TO CREATE
MORE UNSTABLE PREFRONTAL CONDITIONS. NUMEROUS GUSTS 30-35 KTS APPEAR
LKLY. VFR CONDITIONS WILL BE THE RULE THRU 00Z WED.   /CHAPMAN

&&

.PREV DISCUSSION...
QUIET NIGHT IN STORE ACROSS THE AREA WITH WINDS DYING OFF FAIRLY
QUICKLY IN THE EVENING AS THE ATMOSPHERE DECOUPLES. WINDS WILL
BECOME SOUTHERLY OVERNIGHT AS THE SURFACE RIDGE PRESENTLY SITUATED
OVER THE EASTERN PORTIONS OF THE REGION CONTINUES TO TRACK TO THE
EAST...PUTTING OUR AREA ON THE BACKSIDE OF THE HIGH...AND KEEPING
OUR OVERNIGHT LOWS WARMER THAN THIS MORNING. LOWS WILL DROP INTO THE
MID AND UPPER 40S...POSSIBLY STEADYING OUT AND RISING SLIGHTLY IN
OUR SOUTHWESTERN MISSOURI RIVER CORRIDOR AREAS AS A WARM FRONT LIFTS
NORTHWARD INTO THE AREA LATE TONIGHT.  /JM

BIG ISSUES IN THE FCST WILL BE WINDS...UNSEASONABLY COOL WX...AND
PSBL WINTER LIKE CYCLOGENESIS INTO CWA THU NGT INTO FRI. FOR TUES...
BRISK SWLY FLOW OF WARM AND RATHER DRY AIR AHEAD OF STG CDFNT MOVG
SEWD INTO CWA. PREV FCST NEAR 80 SE TO MID 60S NW IN CWA LOOKS GOOD.
LAPSE RATES VERY STEEP WITH ENUF MOISTURE BLO 700MB TO KEEP 20 TO 30
PCT CHC -TSRA DVLPG NEAR CDFNT IN AFTN IN SERN CWA...GOING TO MORE A
POSTFRONTAL MID LVL -SHRA BAND IN THE EVE WITH FNTL CONVERGENCE.
INVERTED V TYPE SOUNDING WOULD IMPLY LCLLY STG WINDS WITH ANY -TSRA
THAT DVLPS IN THE LATE AFTN. OTHER BIG ISSUE IS QUICK BLAST OF WNWLY
WINDS EXPCD BEHIND FNT ASSCD WITH VERY STRONG NRN STREAM WAVE AND
PRES RISES...WITH FAIRLY BRIEF GUSTS TO 40 OR EVEN 50 MPH PSBL IN
NWRN CWA BY NOON. THESE WINDS SHOULD FALL OFF BEHIND FNT WAITING
FOR DEEPER MIXING LATER TUES NGT AND WED...AND WED WILL BE A VERY
BLUSTERY AND COOL DAY WITH SC CLOUDS MAINLY NORTH IN CWA. NEXT BIG
ISSUE IS THE MAJOR UPR TROF CRASHING EWD OVER CWA THU NGT AND
FRI...AND EVEN GFS HAS FINALLY LATCHED ON TO THIS. A COMPOSITE OF
MODELS SHOW BEST RAIN TRACKING EWD OVER CWA...ESP NEAR AND NORTH OF
I90 CORRIDOR...FROM THU AFTN THRU THU NIGHT. MODELS ALL IMPLY RAIN
MIXING WITH OR EVEN CHGG TO A PERIOD OF WET SNOW IN WRN CWA LATER
THU NGT...ESP IN THE 9V9 TO HON AREAS...AND WILL HAVE TO WATCH FOR
THIS UNUSUAL EVENT. OBVIOUSLY TEMPS WILL BE ON UNSEASONABLY COOL
SIDE FOR THU THRU FRI NGT AS THE SYSTEM DRAWS IN COLDER AIR FROM
CANADA...WITH THE SUX TO SLB AREA NOT QUITE AS COOL ON THE SOUTH
SIDE OF THE SYSTEM. AIR MASS MODIFIES DURG THE WEEKEND AHEAD OF
ANOTHER PSBLY MAJOR UPR TROF MOVG EWD INTO THE PLAINS FROM LATER
SUN THRU MID WEEK...SO HAVE POPS FOR THIS TOO./ RYRHOLM
