UPPER LEVEL ANALYSIS HAS LONGWAVE TROF ACROSS THE WESTERN AND
CENTRAL CONUS WITH SHORTWAVE ENERGY EMBEDDED IN THE CYCLONIC FLOW.
ACROSS THE NORTHERN PLAINS...WEST TO SOUTHWEST FLOW IS PRESENT
WITH PARTLY CLOUDY SKIES. A FEW SHOWERS/WEAK STORMS HAVE DEVELOPED
OFF THE HIGHER TERRAIN OF THE BLACK HILLS THIS AFTERNOON. AT THE
SURFACE...A WEAK COLD FRONT BISECTS THE FORECAST AREA...WITH
SOUTHERLY WINDS AHEAD OF IT...AND NORTHERLY WINDS BEHIND IT.
TEMPERATURES RANGE FROM AROUND 70 IN GILLETTE...TO THE MID 80S
ACROSS SOUTH CENTRAL SOUTH DAKOTA.

UNSETTLED WEATHER WILL CONTINUE THIS WEEKEND AS ZONAL FLOW BRINGS
A SERIES OF WEAK DISTURBANCES ACROSS THE REGION. SHOWERS AND
STORMS LOOK TO CONTINUE THROUGH MUCH OF THE COMING WEEK AS THE
UNSETTLED WEATHER PATTERN CONTINUES.

FOR TONIGHT...SURFACE COLD FRONT WILL STALL OUT ACROSS THE SOUTH
DAKOTA PLAINS THIS EVENING. INSTABILITY LATE THIS AFTERNOON INTO
TONIGHT WILL BE GREATEST FROM THE BLACK HILLS EASTWARD...WHERE
SBCAPE VALUES OF 1000 TO AROUND 2000 J/KG ARE EXPECTED. SHEAR WILL
BE MOST FAVORABLE NEAR THE FRONT FOR ISOLATED STRONG
THUNDERSTORMS. THE BETTER CHANCES FOR PCPN WILL LIKELY SHIFT
FURTHER NORTH OVERNIGHT INTO EARLY SUNDAY AS WEAK ENERGY ALOFT IS
PROGGED TO SLIDE ACROSS SOUTHERN MT INTO NORTHERN SD AND ND.

ON SUNDAY...THE SURFACE COLD FRONT SHOULD SHIFT SLOWLY EAST OVER
SOUTH CENTRAL SD INTO WESTERN NEB...WITH THE BETTER CHANCES FOR
SHOWERS AND STORMS GRADUALLY SHIFTING TO SOUTHERN PORTIONS OF THE
CWA IN THE AFTERNOON AND EVENING AS WEAK SHORTWAVE ENERGY
INTERACTS WITH THE BOUNDARY. THE BETTER CHANCES FOR ISOLATED
STRONGER STORMS WILL BE NEAR THE FRONT OVER SOUTH CENTRAL SD
SUNDAY AFTERNOON. THE FRONT WILL EVENTUALLY MOVE SOUTH AND EAST OF
THE AREA SUNDAY NIGHT...WITH SHOWERS AND STORMS ENDING OVERNIGHT
OVER SOUTHERN PORTIONS OF THE CWA.

ACROSS THE NORTHERN PLAINS ON THURSDAY. ZONAL FLOW RETURNS ON
FRIDAY AND SATURDAY. AT THE SURFACE...HIGH PRESSURE WILL BE
LOCATED OVER THE DAKOTAS ON MONDAY WITH SOUTHERLY RETURN FLOW OVER
THE WESTERN PART OF THE FORECAST AREA. A WEAK UPPER SHORTWAVE WILL
CREATE A CHANCE OF SHOWERS AND THUNDERSTORMS ON MONDAY AND MONDAY
NIGHT. A STRONGER WAVE WILL PASS ON TUESDAY WITH WELL-DEFINED
RETURN FLOW AND GOOD 850-700MB THETA-E ADVECTION. THIS SHOULD BE
THE BEST CHANCE OF WIDESPREAD PRECIPITATION IN THE LONG TERM WITH
HEAVY RAIN POSSIBLE OVER PARTS OF WESTERN SD. THERE IS THEN A
CHANCE OF SHOWERS AND THUNDERSTORMS OVER VARIOUS PARTS OF THE
FORECAST AREA EACH DAY FROM WEDNESDAY INTO SATURDAY. TEMPERATURES
WILL BE NEAR AVERAGE.
