AS OF 2AM, THE LINE OF SHOWER AND THUNDERSTORMS CONTINUE ALONG AND
EAST OF THE SISSETON HILLS TRACKING EAST/NORTHEAST AT ABOUT 40 MPH.
WIND GUSTS BETWEEN 70-90 MPH WERE REPORTED ACROSS THE CWA, WITH THE
HIGHEST WIND GUSTS NEAR ALTAMONT SHORTLY BEFORE 1AM. THERE WERE
ALSO SEVERAL FUNNEL CLOUD SPOTTINGS OVER PIERRE AS WELL AS WIND
DAMAGE REPORTS OVER PORTIONS OF EAST CENTRAL SD. WAKE LOW PUSHING
THROUGH BEHIND THE LINE OF STORMS OVER PORTIONS OF NORTHEASTERN SD
AS GUSTS HAVE BEEN BETWEEN 45-55 MPH WITHIN THE POST STRATIFORM
RAIN. DUE TO THIS, ISSUED A SHORT FUSE WIND ADVISORY FOR
ROBERTS/GRANT/DEUEL THROUGH 08Z.
BY 12Z, THE COLD FRONT WILL EXTEND NORTH TO SOUTH ALONG THE SISSETON
HILLS WITH THE NEGATIVE TILTED SHORTWAVE'S AXIS EXTENDING FROM
SOUTHEASTERN MT THROUGH NORTHWESTERN NE. EMBEDDED SHORTWAVE ENERGY
LOOKS TO BRING THE CHANCE OF ELEVATED SPOTTY CONVECTION OVER NORTH
CENTRAL SD INTO ND THIS MORNING WHERE IT WILL TRACK EAST/NORTHEAST
OVER PORTIONS OF NORTHEASTERN SD INTO WESTERN MN LATE MORNING AND
THROUGH THIS AFTERNOON PER CAMS. MUCH OF THE BETTER INSTABILITY WILL
LIE EAST OF OUR CWA CLOSER TO THE FRONT AND LOW. HOWEVER, A FEW
STORMS COULD BECOME SEVERE OVER THE FAR PORTIONS OF WEST CENTRAL MN
PER HRRR. THEREFORE, THE SPC HAS A MARGINAL RISK, LEVEL 1 OUT OF 5,
FOR ISOLATED SEVERE STORMS OVER THE EASTERN PORTIONS OF BIG STONE
AND TRAVERSE COUNTIES IN MINNESOTA THIS AFTERNOON. MAIN THREATS
INCLUDE LARGE HAIL, ONE INCH IN DIAMETER, AND 60 MPH WIND GUSTS.
INSTABILITY WILL BE WEAK FOR THIS AREA WITH CAPE BETWEEN 1000-
1500J/KG MIDDAY THROUGH THE EARLY AFTERNOON AND DIMINISHING TO 500
J/KG OR LOWER BY BY THE LATE AFTERNOON. ANY LINGERING STORMS WILL BE
OUT OF THE CWA BY THIS EVENING. ADDITIONAL ENERGY MAY BRING SPOTTY
RAIN SHOWERS (POSSIBLY A RUMBLE OF THUNDER) OVER CENTRAL SD
OVERNIGHT WITH POPS 25% OR LESS. NO SEVERE WEATHER EXPECTED.
THROUGH THURSDAY A CLOSED LOW DEVELOPS AND WILL TRACK ACROSS
CANADA/NORTHERN PLAINS WITH ANOTHER SHORTWAVE MOVING ACROSS THE
CENTRAL AND NORTHERN PLAINS THROUGH EARLY FRIDAY. A SURFACE LOW
DEVELOPING OUT OF COLORADO AND TRACKING INTO THE CENTRAL PLAINS
ALONG WITH EMBEDDED ENERGY ALOFT OVER MT/ND/SD (AND COLD FRONT) WILL
BOTH BRING ADDITIONAL CHANCES OF RAIN (WEAK THUNDERSTORMS) OVER THE
CWA THURSDAY MORNING THROUGH THURSDAY AFTERNOON. AGAIN, NO SEVERE
WEATHER EXPECTED. GUSTY WINDS EXPECTED BY THE AFTERNOON WITH
POTENTIAL GUSTS OF 30 TO 45 MPH, HIGHEST OVER CENTRAL SD. LUCKILY A
PERIOD OF DRY CONDITIONS MOVE IN THURSDAY EVENING THROUGH FRIDAY.
OVERALL DRY FOR THE WEEKEND WITH THE EXCEPTION OF AREAS ALONG AND
WEST OF THE MO RIVER SATURDAY NIGHT THROUGH SUNDAY NIGHT THAT COULD
SEE ADDITIONAL LIGHT MOISTURE.
COOLER AIR MOVES IN BEHIND THE COLD FRONT WITH HIGHS IN THE 70S TO
THE LOWER 80S WEST OF THE SISSETON HILLS (STILL COULD REACH THE MID
80S EAST OF HERE). OVERNIGHT LOWS IN THE 50S WITH MUCH COOLER HIGHS
FOR THURSDAY IN THE 70S. WARMUP FRIDAY BACK IN THE 80S AND BEHIND
THE COLD FRONT HIGHS FOR THE WEEKEND WILL BE MUCH COOLER ABOUT 5-10
DEGREES BELOW AVERAGE.
