THE FIRST OF TWO UPCOMING WINTER SYSTEMS MOVES INTO THE REGION
THIS MORNING AND CONTINUES THROUGH THURSDAY EVENING BRINGING RAIN,
SNOW, AND THE POTENTIAL FOR FREEZING RAIN. TEMPERATURES WILL PLAY A
KEY ROLE IN EXACT PRECIPITATION TYPE, SO LOW CONFIDENCE ON SNOWFALL
TOTALS AND EXACT PRECIPITATION TYPE. AS OF NOW, SNOW AMOUNTS OF 4 TO
8 INCHES IS EXPECTED NORTH OF HIGHWAY 212, WITH THE HIGHEST SNOW
TOTALS OVER THE LEOLA HILLS AND THE EASTERN SLOPES OF THE SISSETON
HILLS. SOUTH OF HIGHWAY 212, HALF INCH TO 3 INCHES OF SNOW IS
EXPECTED. WITH THE ONSET OF THE EVENT, THERE MAY BE SOME HELP FROM
THE WARM GROUND IN PREVENTING SNOW FROM STICKING ON SIDEWALKS AND
ROADWAYS UNTIL IT COOLS FURTHER. THERE WILL ALSO BE PLENTY OF TIME
FOR COMPACTION TO LIMIT THE ACCUMULATIONS. SO WHILE UPWARDS OF 6 PLUS
INCHES OF SNOW MAY FALL TO THE GROUND, CONFIDENCE IS LOW ON ACTUALLY
SEEING THESE HIGHER ACCUMULATIONS AND THE ASSOCIATED IMPACTS.
FREEZING RAIN IS POSSIBLE LATE THIS EVENING THROUGH THURSDAY MORNING
AS WELL TO PARTS OF EASTERN SOUTH DAKOTA, PARTICULARLY IN THE
WATERTOWN AREA. WHILE CONFIDENCE IS LOW, PORTIONS OF DAY AND CLARK
COUNTIES, EASTWARD THROUGH GRANT AND DEUEL COUNTIES MAY SEE UPWARDS
OF A TENTH OF AN INCH OF ICE. STRONG EASTERLY WINDS WILL GUST UP TO
25 TO 35 MILES PER HOUR TODAY, DECREASING THURSDAY TO GUST UP TO 20
TO 30 MILES PER HOUR. THE COMBINATION OF FALLING SNOW AND STRONG
WINDS WILL CAUSE DECREASED VISIBILITY AT TIMES, AS LOW AS HALF A MILE
TODAY. NO WHITEOUT CONDITIONS ANTICIPATED. A WINTER WEATHER ADVISORY
IS IN EFFECT FOR ALL COUNTIES EXCEPT JONES, LYMAN, AND BUFFALO
THROUGH THURSDAY.
A SECOND SYSTEM WILL MOVE IN FROM THE WEST THURSDAY NIGHT THROUGH
SATURDAY BRINGING POTENTIAL FOR MORE FREEZING RAIN AND ADDITIONAL
SNOW. IMPACTS TO TRAVEL ARE EXPECTED. PROBABILITY OF 6" OF SNOWFALL
OR MORE IS 60 TO 95% ALONG AND NORTHWEST OF A LINE FROM EAGLE BUTTE
TO SISSETON, HIGHEST OVER NORTH CENTRAL SD. PROBABILITY OF 8" OR MORE
OF SNOWFALL IS 40 TO 75% FOR THIS SAME AREA, HIGHEST OVER NORTH
CENTRAL SD. FREEZING RAIN WILL BE POSSIBLE THURSDAY NIGHT INTO FRIDAY
MORNING ALONG AND SOUTH OF HIGHWAY 212.
HIGHS FOR TODAY THROUGH THE END OF THE WEEK WILL RANGE IN THE 30S TO
AROUND 40 WITH LOWS RANGING IN THE 20S.
