SUBTLE SHORT WAVES EMBEDDED IN THE SW FLOW ALOFT ISOLD TSTMS COULD
DEVELOP JUST ABOUT ANYWHERE ACROSS WRN SD. BEST SHEAR WILL BE
FOUND ACROSS NWRN SD.

COLD FRONT WILL THEN SWEEP THROUGH THE CWFA LATER THIS EVE AND
OVERNIGHT. PRES RISES OF 5-7MB/3HR WILL SUPPORT GUSTY NW

FOUND...SO HAVE POSTED A WIND ADVISORY THAT AREA.

AFTERNOON AS SFC HIGH BUILDS INTO THE WRN DAKOTAS. LARGE SCALE
SUBSIDENCE WILL BRING MOSTLY SUNNY AND DRY CONDITIONS TO THE AREA.
HEAT INDICES MAY APPROACH 100F IN SCNTRL SD BEFORE SLIGHTLY COOLER
AIR FILTERS INTO THE AREA...SO WILL ALLOW HEAT ADVISORY TO
CONTINUE THAT AREA THROUGH 00Z THURSDAY.

THURSDAY...STRONG SHORT WAVE EMBEDDED IN THE MONSOONAL FLOW WILL
ADVECT OUT OF THE CNTRL ROCKIES AND INTO THE NRN PLAINS AND BRING
A GOOD CHANCE OF TSTMS TO OUR AREA THURSDAY AFTN/NIGHT. SFC LOW
DEEPENING OVER ERN CO/CNTRL PLAINS WILL DRAW COOLER/MOIST AIR INTO
OUR CWFA AND BRING AN END TO THE HEAT ADVISORY CONDITIONS OVER
CNTRL SD.

EXTENDED...MEDIUM RANGE MODELS CONTINUE TO SHOW AN ACTIVE PATTERN TO
END THE WEEK AS THE UPPER RIDGE REMAINS OVER THE SOUTHERN PLAINS
INTO THE MIDWEST...BRINGING A MONSOONAL FLOW PATTERN TO THE REGION.
