DISCUSSION
ISSUED AT 238 AM CST THU JAN 29 2026
A NORTHWEST TO SOUTHEAST WAA BAND OF LIGHT SNOW CONTINUES TO AFFECT
CENTRAL SD EARLY THIS MORNING. BEST RETURNS REMAIN WEST RIVER,
THOUGH PIERRE HAS CONSISTENTLY BEEN DOWN TO 1 TO 2 MILES. MOBRIDGE,
ON THE OTHER HAND, HAS YET TO SATURATE. EXPECT THIS INITIAL BAND TO
CONTINUE THROUGH MORNING. HI-RES MODELS INDICATE A BRIEF BREAK IN
THE AFTERNOON BEFORE SNOW FILLS BACK IN THIS EVENING AND LINGERS
INTO FRIDAY MORNING ON THE EDGE OF THE ARCTIC FRONT WITH A HIGH
BUILDING IN FROM THE NORTHEAST. UP TO AN ADDITIONAL INCH OF SNOW IS
EXPECTED WITH HIGHEST AMOUNTS ALONG THE WESTERN EDGE OF THE CWA,
BASICALLY WEST OF A LINE FROM MCLAUGHLIN TO MURDO. WITH WINDS
REMAINING LIGHT, THE IMPACT FROM THIS SYSTEM IS MINIMAL.
WHEN THIS ROUND ENDS BY FRIDAY AFTERNOON, ALL EYES TURN TO SATURDAY.
SURFACE HIGH PRESSURE EXITS TO THE SOUTHEAST AND RETURN FLOW SETS
UP. INCREASING SOUTHERLY WINDS AND AN UPPER RIDGE MEAN WARMER
TEMPERATURES ON SATURDAY WITH HIGHS WEST RIVER IN THE MID TO UPPER
30S. HOWEVER, AN UPPER TROUGH AND SFC FRONT QUICKLY PUSH IN FROM THE
WEST BRINGING SOME ADDITIONAL LIGHT PRECIPITATION. CONFIDENCE IN
TIMING IS STILL LOW. WINDS APPEAR TO DIMINISH SLIGHTLY AS SNOW
STARTS FALLING ON SOME MODELS, BUT ENSEMBLES CONTINUE TO BLEED
EVERYTHING TOGETHER. ANY ACCUMULATIONS LOOK LIGHT, AROUND AN INCH OR
LESS, BUT TIMING IS EVERYTHING BECAUSE TEMPERATURE, PRECIPITATION
TYPE AND BLOWING SNOW POTENTIAL REVOLVE AROUND IT.
TEMPERATURES RETURN TO NEAR OR ABOVE CLIMO NORMS ON SATURDAY AND
REMAIN ABOVE AVERAGE THROUGH NEXT WEEK.
