AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY
NATIONAL WEATHER SERVICE RAPID CITY SD
534 PM MDT SUN AUG 25 2013

.SHORT TERM...THIS EVENING THROUGH MONDAY NIGHT
ISSUED AT 236 PM MDT SUN AUG 25 2013

WATER VAPOR IMAGERY SHOWS SOUTHWEST FLOW CONTINUING ALOFT AS
UPPER LOW DRIFTS OFFSHORE THE WESTERN CANADIAN COAST...AND STRONG
RIDGE REMAINS OVER THE MISSISSIPPI VALLEY. A VORT MAX ASSOCIATED
WITH A STRENGTHENING JET MAX ACROSS THE GREAT BASIN INTO THE
NORTHERN ROCKIES WILL CONTINUE TO PUSH ACROSS WYOMING TONIGHT.
SURFACE ANALYSIS SHOWS BOUNDARY STRETCHING ACROSS SOUTH CENTRAL SD
INTO ND. KUDX RADAR SHOWS ISOLATED STORMS WHICH DEVELOPED ACROSS
THE BLACK HILLS SLIDING E/NE INTO THE ADJACENT PLAINS.
TONIGHT...VORT MAX WILL PUSH ACROSS THE REGION...BUT ATMOSPHERE
OVER THE PLAINS STILL LOOKS TOO MARGINALLY UNSTABLE FOR ANY
ADDITIONAL SURFACE BASED CONVECTION TO DEVELOP. ISOLATED ELEVATED
PRECIP MAY DEVELOP ACROSS NW SD...BUT AS WAS THE CASE EARLIER THIS
MORNING...THINK THIS WILL END UP BEING VIRGA. A FEW ADDITIONAL
STORMS MAY DEVELOP EARLY THIS EVENING OVER THE BLACK HILLS AREA
AND ADJACENT PLAINS JUST UPSTREAM TO THE NORTHEAST...BUT WILL
DISSIPATE QUICKLY WITH DIURNAL COOLING.

UPPER RIDGE WILL REMAIN IN PLACE ACROSS THE CENTRAL CONUS MONDAY
WITH CONTINUED SW FLOW ALOFT OVER THE AREA. THINK THE HILLS AND
PLAINS ACROSS NORTHWEST SOUTH DAKOTA COULD SEE ISOLATED CONVECTION
TOMORROW AFTERNOON...BUT ANY PRECIP THAT DEVELOPS WILL END BY THE
EARLY EVENING. WARM TEMPS WILL RETURN TOMORROW ACROSS CENTRAL SD.
DEWPOINTS WILL BE IN THE UPPER 40S AND 50S TOMORROW...BUT MAY BE IN
THE LOWER TO MID 60S OVER SOUTH CENTRAL SD. THIS WOULD RESULT IN
HEAT INDICES AT OR JUST ABOVE 100F. THIS IS MARGINAL FOR HEAT
ADVISORY CRITERIA...SO WILL LET MID SHIFT MAKE FINAL CALL ON
WHETHER HEADLINES ARE NEEDED OR NOT.

&&

.LONG TERM...TUESDAY THROUGH SUNDAY
ISSUED AT 236 PM MDT SUN AUG 25 2013

A STRONG UPPER HIGH OVER THE CNTRL PLAINS WILL REMAIN
NEARLY STATIONARY OR POSSIBLY RETROGRADE SLIGHTLY WEST NEXT
WEEK...AND BRING CONTINUED ABOVE AVERAGE TEMPS TO THE NRN PLAINS.
PERSISTENT W/SW FLOW ALOFT ACROSS OUR REGION WILL BRING PERIODIC
CHANCES FOR THUNDERSTORMS AS EMBEDDED WAVES MOVE THROUGH.

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z MONDAY EVENING)
ISSUED AT 530 PM MDT SUN AUG 25 2013

ISOLATED TSTMS ARE POSSIBLE THIS EVE...MAINLY OVER PARTS OF NWRN
SD WITH BRIEF MVFR VSBY...GUSTY WINDS AND SMALL HAIL.
OTHERWISE...VFR CONDITIONS EXPECTED THROUGH THE PERIOD.
