UPDATE
ISSUED AT 820 PM CST MON JAN 5 2026
FOGGY CONDITIONS HAVE STARTED TO EXPAND SOUTH AND WEST OUT OF FAR
NORTHEAST SD AND WEST CENTRAL MN THIS EVENING. SFC OBS, WEBCAMS
AND SPOTTER REPORTS INDICATE VISIBILITY HAS DROPPED TO A HALF MILE
OR LESS ACROSS PARTS OF NORTHEAST AND EAST CENTRAL SD. ADDED SOME
ADDITIONAL ZONES TO THE DENSE FOG ADVISORY WITH THE POTENTIAL FOR
NEEDING FURTHER EXPANSION WEST IN TIME. GUIDANCE SUGGESTS FOG
COULD LIFT AND VISIBILITIES IMPROVE ACROSS THE JAMES VALLEY
OVERNIGHT BY 09Z BUT HANG TOUGH LONGER ACROSS OUR EASTERN ZONES
INTO TUESDAY MORNING. ALSO, MADE SOME ADJUSTMENTS TO POPS TO BRING
THEM IN LINE WITH CURRENT RADAR IMAGERY. DEALING WITH A COUPLE OF
AREAS OF MAINLY LIGHT PRECIPITATION MOVING ACROSS EAST CENTRAL SD
AND WEST CENTRAL MN THIS EVENING AND ANOTHER AREA ACROSS WESTERN
AND CENTRAL SD ASSOCIATED WITH ANOTHER WEAK DISTURBANCE MOVING IN.
NOT EXPECTING MUCH IN THE WAY OF MOISTURE WITH EITHER AREA BUT A
BRIEF BOUT OF SPRINKLES OR LIGHT RAIN OR FREEZING RAIN OR SNOW
CAN'T BE RULED OUT.

DISCUSSION
ISSUED AT 230 PM CST MON JAN 5 2026
AS OF 2 PM CST, A DENSE FOG ADVISORY REMAINS IN EFFECT FOR FAR
NORTHEAST SD AND WEST CENTRAL MN UNTIL NOON TUESDAY. DENSE FOG IS
EXPECTED TO SPREAD WEST BUT EXTENT IS UNCERTAIN AT THIS TIME. WILL
LET THE NEXT SHIFT EXTEND AS NECESSARY. THERE ARE ALSO SOME LIGHT
SHOWERS MOVING ACROSS SOUTH CENTRAL SD. TEMPERATURES ARE
GENERALLY IN THE MID 30S TO MID 40S WITH LIGHT WINDS.
FREEZING RAIN WILL BE POSSIBLE LATE THIS EVENING INTO THE OVERNIGHT
HOURS MAINLY IN CENTRAL SD AND FAR EAST SD ALONG WITH WEST CENTRAL
MN. AREAS OF FOG/FREEZING FOG ARE EXPECTED TO CONTINUE OVER FAR
NORTHEAST SD AND WEST CENTRAL SD, AND SPREADS WEST TO THE JAMES
RIVER LATER TONIGHT. THIS, COMBINED WITH THE FEW HUNDREDTHS OF AN
INCH OF FREEZING RAIN ACCUMULATIONS, COULD CREATE SLICK ROADS AND
SIDEWALKS FOR THE MORNING COMMUTE. RAIN, BECOMING FREEZING RAIN AND
SNOW, WILL MOVE INTO CENTRAL SD AFTER MIDNIGHT, ASSUMING
TEMPERATURES FALL BELOW FREEZING, OTHERWISE IT WILL REMAIN RAIN.
SNOW ACCUMULATIONS ARE LITTLE TO NONE, WITH A FEW HUNDREDTHS OF AN
INCH OF ICE ACCUMULATION POSSIBLE, AGAIN, MAKING FOR POSSIBLY SLICK
CONDITIONS FOR THE MORNING COMMUTE. OUR NEXT CHANCE FOR SOME
PRECIPITATION LOOKS TO BE FRIDAY INTO EARLY SATURDAY MORNING. THE
CENTER OF THE LOW PRODUCING THIS SNOW LOOKS TO STAY A GOOD WAYS
SOUTH OF US, SO THIS IS EXPECTED TO BE VERY LIGHT SNOW WITH LITTLE
ACCUMULATION. HOWEVER, THIS IS 4-5 DAYS OUT SO THINGS COULD CHANGE.
THE NEXT FEW DAYS LOOK TO BE DRY AND RELATIVELY MILD TEMPERATURE
WISE WITH HIGHS IN THE 30S TO 40S, POTENTIALLY REACHING INTO THE 50S
IN SOUTH CENTRAL SD. SATURDAY WILL BE A LITTLE COOLER AS SOME COLDER
AIR MOVES IN BEHIND THE LOW, BUT THIS SHOULD BE SHORT LIVED AS
STRONG WAA MOVES IN FOR THE END OF THE WEEKEND AND BEGINNING OF NEXT
WEEK.
