AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA
NATIONAL WEATHER SERVICE SIOUX FALLS SD
505 AM CDT TUE AUG 21 2007
.DISCUSSION...
OUTSIDE SOME QUIET WEATHER TO BE FEATURED EARLY THE NEXT COUPLE OF
DAYS...ALL SIGNS POINT TOWARD RAINFALL BEING A SIGNIFICANT CONCERN
AGAIN OVER THE AREA...ESPLY THIS EVENING...AND AGAIN WED NIGHT AND
EARLY THU.
SO MANY BOUNDARIES RIGHT NOW ITS HARD TO FIND THE FOREST FOR THE
TREES. WK FRONTAL WAVE HAVE MOVED INTO MN...DRAGGING SFC BNDRY THRU
MOST OF CWA ATTM. SFC WINDS TURNING NLY BEHIND WAVE DRAGGING MORE
LOW CLOUDS SWRD THRU I29 CORRIDOR AND INTO FAR NRN PORTIONS OF NW IA
ATTM. LOW ENOUGH CIGS THAT DENSE FOG HAD BECOME AN ISSUE EARLIER IN
THE NIGHT...AND POSTED A DENSE FOG ADVISORY PRIMARILY FOR THE
ELEVATED AREAS. HARD TO FIGURE HOW FAR WL BE ABLE TO PUSH/DEVELOP
WWRD INTO MORE WLY LOW LVL COMPONENT EARLY TDA AHEAD OF WKNG SFC
RIDGE IN THE CNTRL DKTS/NEBRASKA. OTHERWISE...SHUD BE QUIET DAY
UNTIL WAVE PUSHING THRU NRN ROCKIES REACHES AREA LT AFTN. EXPECT
FRONTAL BNDRY TO REORGANIZE ACRS HEART OF CWA. MAX PWAT HAS
CONGEALED JUST TO S/SE OF AREA...ALL READY FOR USE TONIGHT. MDLS
HAVING REAL ISSUES FINDING THE REAL BOUNDARY...AND MAY HAVE TO
REALLY WAIT TO PIN DOWN BEST THREAT TOWARD MIDDAY AS THINGS SHAKE
OUT OF THE MESS. WIND PROFILES HAVE A LONG WAY TO GO FROM NLG
MORNING LOOK TO MAKE THREATENING PROFILE...ALREADY STARTING THRU
HIGH PLAINS WITH JET MAX STARTING TO PUSH THRU NRN ROCKIES AND LLJ
TURNING IT UP A NOTCH OUT W. HAVE SEEN ENHANCEMENT OF MID CLDS THRU
SERN MT AND NWRN SD...WITH EVEN A FEW WK RETURNS. THESE SHRA AND
PERHAPS ISOLD TSRA SHUD REACH NWRN CWA MIDDAY...AS OTHER LOWER
CLOUDS WORK ON SCOURING OUT. TO THE S...WL BE A VERY WARM AND MOIST
AIRMASS BY MID AFTN...BUT ALL MDLS SHOW 300+ CINS PRIOR TO ONSET OF
WHATEVER DESTROYS THE PROJECTED CAP PER USUAL BIAS. SOME SEEMS TO BE
POOR LOW LVL MOISTURE FCST. STILL LOOKS AS IF WL REMAIN CAPPED FOR
GOODLY SHARE OF AFTN...AND STRENGTH MAKES ONE WONDER IF NOT ALL OF
AFTN PD WUD REMAIN DRY ACRS S WITH MORE LKLY FLASH POINT CLOSER TO
SFC WAVE ACRS NERN NEBRASKA TOWARD EVENING...BEFORE LLJ KICKS THINGS
ALG/N OF BNDRY UP MORE INTO THE EVNG. SVR THREAT IN PLACE AGAIN
MAINLY IN AN AREA S OF A LINE FROM MWM TO YKN...PARTICULARLY ACRS
NERN NEBRASKA AND NWRN IA. WL HAVE TO AGAIN MENTION A THREAT FOR A
TORNADIC STORM NERN NEBRASKA THRU NWRN IA ALG LOW LVL BNDRY...WITH
LOW LCL/NICELY DISTRIBUTED SHEAR PROFILE...INCLUDING A GOOD LOW LVL
ACCELERATION DUE TO HIGH THETA E AIR NR SFC.
PRECIPITATION RATE LKLY TO BE INTENSE AGAIN WITH ANY STORMS WHICH
DEVELOP DUE TO WARM CLOUD DEPTH...AND FFG ON ORDER OF 1-2 INCHES ON
BOTH 1H/3H RATES LEAVES VERY SUSCEPTABLE ONCE AGAIN. WL ISSUE FFA
FOR I90 AREAS OF SW MN DOWN THRU KSUX AREA FOR LT AFTN/EVNG HOURS.
ACTION SHUD PUSH S OF AREA LTR TONIGHT...AND LEAVE A TEMPORARY BREAK
IN PCPN ON WED. LTR IN DAY...WL SLOWLY SEE CHC FOR PCPN SPREAD BACK
IN FROM SW WITH NEXT WAVE INDUCING RETURN FLOW ACRS BNDRY WHICH
STALLS ACRS SRN NEBRASKA AND CNTRL IA. REALLY NICE SETUP FOR PCPN
ESPLY LTR WED NIGHT INTO THU MORNING THRU MUCH OF CWA ALG/S OF I90
WITH NRN STREAM IMPULSE ENHANCING LLJ ACRS BNDRY WITHIN RIGHT
ENTRANCE REGION...WITH GOODLY MOISTURE TRANSPORT. ANY SVR THREAT
WITH THIS WOULD SEEMS TO BE FAIRLY LIMITED TO HAIL/MARGINAL WIND
ACRS FAR SRN CWA AS STORMS SHUD BE ELEVATED AND INSTABILITY QUITE A
BIT LOWER THAN TDA.
AWAITING WHAT LOOKS TO BE WEEKEND DRYING OUT WITH SEASONABLE TEMPS.

.AVIATION...
WEAK LOW LEVEL FLOW WITH SOME MIXING AND SUBSDNCE IS HAVING SOME
SUCCUESS KEEPING LOW CLOUDS AND FOG FROM WRN AND SRN PART OF FCST
AREA. ERYR FOG DVLPMNT AT HON GOT KNOCKED BACK. OF COURSE BEST
RECENT RAINFALL AREA IS IN SWRN MN...SO THE AREA OF IFR CIGS AND
VSBYS IN FOG IS THERE BACK INTO SERN SD FROM FSD N...AND INTO NWRN
IA FROM FSD TO STORM LAKE. THIS SHUD STAY PRETTY MICH THE SAME TILL
ARND 15Z AFTER WHICH HEATG AND SLOW ADVANCE OF WEAK MIXING WILL AID
IN STEADY IMPROVEMENT. MVFR CIGS MAY LINGER SWRN MN TO ARND 18Z.
REST OF AVIATION HAZARDS WILL CENTER ON SIGNIFICANT AND WDSPRD
CONVECTION AFT 21Z...MAINLY SERN HALF OF FCST AREA. THERE SHUD BE
SOME MIXG AS CONVECTION PULLS OUT LATE TNGT SO THERE CUD BE SOME LOW
CIGS INCLUDG IFR OVER SERN PART OF FCST AREA AFT 06Z...BUT DONT
EXPECT THE FOG TO THE EXTENT WE HAVE IN SWRN MN NOW.
