.DISCUSSION...CURRENT SURFACE ANALYSIS PLACES TROF OF LOW PRESSURE
STRETCHING FROM CENTRAL SASKATCHEWAN THROUGH EASTERN MONTANA AND
INTO EASTERN WYOMING. WEST-SOUTHWEST FLOW ALOFT REMAINS OVER THE
REGION...WITH A SHORT WAVE WAVE EDGING THROUGH NORTHEAST WYOMING.
SOME CONVECTION HAS ALREADY STARTED OVER EASTERN WYOMING AND FAR
WESTERN SOUTH DAKOTA. FOR THE REMAINDER OF THIS AFTERNOON INTO THIS
EVENING...AFOREMENTIONED SHORT WAVE WILL CONTINUE ITS PROGRESS
EASTWARD ACROSS THE CWFA. APPEARS THAT THE BEST LIFT ALONG WITH THE
BEST THETA-E ADVECTION WILL BE GENERALLY OVER THE NORTHERN BLACK
HILLS INTO NORTHWEST SOUTH DAKOTA...WHILE CAPE VALUES OF 1600+ J/KG
ARE EXPECTED ACROSS ALL OF THE WESTERN CWFA. THOUGH SEVERE WEATHER
WILL BE A POSSIBILITY OVER ANY PART OF WESTERN SOUTH DAKOTA...AM
THINKING THE BEST CHANCES WILL BE OVER NORTHWEST INTO WEST CENTRAL
SOUTH DAKOTA...PARTICULARLY INTO THE EVENING HOURS. ALSO...SOME OF
THESE STORM COULD BE SLOW MOVING...PARTICULARLY RIGHT MOVERS. WILL
HAVE TO KEEP AN EYE OUT FOR LOCALIZED HEAVY RAINFALL. FOR
TOMORROW...HIGHS ARE EXPECTED TO PUSH INTO THE 90S...WITH BREEZY
CONDITIONS AGAIN OVER SOUTH CENTRAL SOUTH DAKOTA AS TIGHT PRESSURE
GRADIENT REMAINS. ANOTHER WAVE IS EXPECTED TO MOVE THROUGH SOUTHWEST
FLOW ALOFT WHILE MODELS ARE AGAIN FORECASTING CAPE VALUES OF
1500-2000 J/KG ACROSS MUCH OF THE SOUTH DAKOTA PORTION OF THE CWFA.
THEREFORE...HAVE PUSHED POPS UP SOME OVER THIS AREA. THUNDERSTORMS
THAT DO DEVELOP WILL SLOWLY PUSH EASTWARD...EXITING THE CWFA EARLY
IN THE MORNING. THURSDAY WILL AGAIN BRING A WAVE MOVING THROUGH.
BOTH GFS AND NAM ARE INDICATING CAPE VALUES OF 2000+ J/KG OVER MUCH
OF THE EASTERN AND NORTHERN CWFA IN THE AFTERNOON AND EVENING HOURS.
A COOL FRONT WILL MOVE THROUGH LATE THURSDAY NIGHT INTO EARLY FRIDAY
MORNING. THIS WILL BRING COOLER TEMPERATURES...WITH MANY AREAS
SEEING HIGHS IN THE 80S. UPPER TROF SWINGING THROUGH BEHIND THE
FRONT WILL BRING A CHANCE FOR THUNDERSTORMS...PARTICULARLY OVER THE
DAYTIME HOURS.
EXTENDED...UPR RIDGE WILL SLOWLY BUILD ACRS THE REGION RESULTING IN
A WARMING TREND. WITH LITTLE SIGNALS FOR ANY SUBSTANTIAL PCPN AND TO
REMAIN IN COORD WITH SURROUNDING OFFICES...WILL KEEP MUCH OF THE
EXTENDED FORECAST DRY.

CENTRAL SOUTH DAKOTA OVERNIGHT AND 5 TO 15KTS ELSEWHERE.

SLIGHTLY...CURRENTLY IT LOOKS LIKE RELATIVE HUMIDITIES WILL BE A
LITTLE HIGHER TOMORROW AND WINDS NOT AS STRONG. EXPECT HIGH
TEMPERATURES IN THE MID 90S...MINIMUM RELATIVE HUMIDITIES AROUND 20
TO 30 PERCENT...AND SOUTHERLY WINDS AROUND 20 MPH. DUE TO THE
