Hazardous Weather Outlook

.DAY ONE…TODAY AND TONIGHT

WINTER WEATHER…
PRECIPITATION WILL MOVE IN TONIGHT ASSOCIATED WITH AN AREA OF LOW
PRESSURE MOVING INTO THE PLAINS. THIS WILL START AS RAIN BEFORE
CHANGING TO SNOW WEST OF THE JAMES RIVER BY MIDNIGHT AND AFTER
MIDNIGHT ALONG THE HURON TO MARSHALL CORRIDOR. THE RAIN MAY MIX
WITH SNOW AND SLEET EAST OF THE JAMES RIVER ACROSS THE REST OF
SOUTHEAST SOUTH DAKOTA AND SOUTHWEST MINNESOTA DURING THE
OVERNIGHT.

.DAYS TWO THROUGH SEVEN…SUNDAY THROUGH FRIDAY

NEAR BLIZZARD TO BLIZZARD CONDITIONS ARE POSSIBLE ACROSS PORTIONS
OF THE AREA LATER TONIGHT INTO SUNDAY NIGHT. THE GREATEST THREAT
OF SIGNIFICANT SNOW STILL LOOKS TO BE FROM THE JAMES VALLEY TO
BROOKINGS AND MARSHALL…WHERE 8 TO 14 INCHES SEEM POSSIBLE.
AFTER INITIALLY BEGINNING AS RAIN…THESE AREAS WILL GO OVER TO
SNOW LATER TONIGHT AND CONTINUE THROUGH SUNDAY NIGHT. WINDS WILL
CONTINUE TO INCREASE SUNDAY INTO SUNDAY NIGHT…WITH GUSTS TO 50
MPH POSSIBLE. THIS COMBINED WITH THE FALLEN SNOW MAY CREATE
BLIZZARD CONDITIONS THROUGH THE NIGHT. FURTHER SOUTHEAST…FROM
BON HOMME COUNTY TO SIOUX FALLS TO WINDOM…CONFIDENCE IS LOWER.
HOWEVER IT APPEARS THE RAIN WILL CHANGE OVER TO SNOW DURING THE
DAY SUNDAY…WITH LIGHTER SNOW CONTINUING INTO SUNDAY NIGHT.
CURRENT INDICATIONS ARE THAT 2 TO 6 INCHES MAY FALL IN THIS AREA.
WINDS IN THIS REGION WILL INCREASE LATER SUNDAY AFTERNOON…WITH
GUSTS TO 50 MPH POSSIBLE INTO SUNDAY NIGHT. THESE WINDS COMBINED
WITH THE FALLEN SNOW MAY CREATE BLIZZARD CONDITIONS HERE AS WELL.
AREAS SOUTHEAST OF THE ABOVE AREA WILL SEE LESS SNOW…ALTHOUGH
WINDS ARE STILL EXPECTED TO INCREASE BY SUNDAY NIGHT. THUS
BLOWING AND DRIFTING OF ANY SNOW THAT DOES FALL WILL STILL BE
POSSIBLE. SHIFTS IN THE STORM TRACK ARE STILL POSSIBLE…AND ANY
SHIFT WILL HAVE SIGNIFICANT IMPACTS ON WHERE THE HEAVIEST SNOW
FALLS AND BLIZZARD CONDITIONS OCCUR…AND WHERE MAINLY RAIN
OCCURS. IF YOU HAVE TRAVEL PLANS SATURDAY NIGHT INTO SUNDAY NIGHT
PLEASE STAY TUNED FOR THE LATEST DEVELOPMENTS.
