Another cold night expected across the region, with lows ranging from the negative teens along the highway 14 corridor, to around zero along the Missouri river. Wind chills will continue to range from 20 to 30 below zero across portions of southwest Minnesota through the night. Attention then turns to our winter storm on Thursday. Timing is a bit slower, with accumulating snow expected to start in our west around midnight, but not until early to mid afternoon across southwest Minnesota. Total snow amounts are expected to be highest west of the James river closer to the Missouri river, where 5 to 10 inches are possible. Amounts will generally decrease as you head northeast, with 3 to 8 inches across most of southeast South Dakota into southwest Minnesota.
THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST SOUTH DAKOTA…
SOUTHWEST MINNESOTA…NORTHWEST IOWA…AND NORTHEAST NEBRASKA.
.DAY ONE…TODAY AND TONIGHT
ALTHOUGH WIND SPEEDS WILL BE DECREASING TONIGHT…THE AIR
TEMPERATURE WILL BE COLD ENOUGH TO PRODUCE WIND CHILL VALUES
GENERALLY IN THE 20 BELOW TO 25 BELOW RANGE IN EAST CENTRAL SOUTH
DAKOTA AND SOUTHWEST MINNESOTA TONIGHT AND EARLY WEDNESDAY.
ELSEWHERE…WIND CHILL VALUES WILL RANGE FROM ABOUT 10 BELOW TO
20 BELOW ZERO.
.DAYS TWO THROUGH SEVEN…WEDNESDAY THROUGH MONDAY
SNOW IS EXPECTED OVER THE AREA THURSDAY AND THURSDAY
NIGHT…ENDING FROM SOUTHWEST TO NORTHEAST ON FRIDAY. AREAS OF
BLOWING SNOW WILL LIKELY ACCOMPANY THE SNOWFALL ON THURSDAY AND
THURSDAY EVENING. OVERALL…FOUR AND A HALF TO SIX AND HALF
INCHES OF SNOW WILL BE COMMON IN THIS AREA…ALTHOUGH AMOUNTS OF
7 TO 8 INCHES MAY OCCUR IN SOUTH CENTRAL SOUTH DAKOTA.
ANOTHER LOW PRESSURE SYSTEM APPROACHING LATE THIS WEEKEND MAY
THREATEN WINTER STORM CONDITIONS AGAIN LATE SUNDAY OR MONDAY.
THIS SECOND POTENTIAL STORM IS FAR FROM CERTAIN…BUT IF IT
DEVELOPS…COULD PRODUCE MORE WIND AND BLOWING SNOW THAN THE
FIRST STORM THIS WEEK.
