DISCUSSION

A NORTHWEST TO SOUTHEAST WAA BAND OF LIGHT SNOW CONTINUES TO
AFFECT SOUTH CENTRAL SD EARLY THIS MORNING, STAYING WEST AND
SOUTHWEST OF SIOUX FALLS. BEST RETURNS REMAIN ALONG THE MISSOURI
RIVER. 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 HALF AN INCH OF SNOW IS EXPECTED WITH HIGHEST
AMOUNTS WEST OF MITCHELL. 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 PUSHING IN FROM THE WEST ON SATURDAY WITH HIGHS
ALONG THE MO IN THE MID 20S TO LOWER 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
WITH HIGHEST AMOUNTS NORTH OF I-90, BUT TIMING IS EVERYTHING
BECAUSE TEMPERATURE, PRECIPITATION TYPE AND BLOWING SNOW
POTENTIAL REVOLVE AROUND IT.
TEMPERATURES RETURN TO NEAR OR ABOVE CLIMO NORMS ON SUNDAY AND
REMAIN ABOVE AVERAGE THROUGH NEXT WEEK.
