DISCUSSION
ISSUED AT 1043 AM CST FRI FEB 20 2026
NORTHWEST FLOW AND AN UPPER LOW OVER LAKE SUPERIOR CONTINUE TO PULL
SOME FLURRIES INTO THE REGION TODAY. THE UPPER LOW IS PRETTY SLOW
MOVING AND MAY KEEP SOME FLURRIES OVER WEST CENTRAL MN INTO THIS
EVENING. THOUGH RADAR RETURNS THIS MORNING INDICATE MORE WIDESPREAD
LIGHT SNOW, THINK THE DRIER AIR AND LACK OF FORCING IS UNDERCUTTING
MOST OF IT WEST OF I-29.
HIGH PRESSURE BUILDS IN FROM THE NORTHWEST TONIGHT THROUGH SATURDAY
NIGHT. THIS CWA WILL BE AT THE EDGES OF THE HIGH FOR THE NEXT 48
HOURS ALLOWING NORTHWEST WINDS TO BECOME BREEZY (20 TO 35 MPH) UNDER
THE JET. COTEAU WINDS, WITH 50 KTS AT 700 MB ON SUNDAY, MAY NEED AN
NBM 90TH BOOST IN THE GRIDS TO REFLECT SOME 40 KT GUSTS.
THERE'S A LACK OF CONSISTENCY IN THE MODELS STARTING TUESDAY
REGARDING SYSTEM TRACK AND TIMING AND PRECIP CHANCES. THE ECMWF IS
MUCH WEAKER ON A MIDWEEK TROUGH THAN THE LATEST 12Z GFS, KEEPING THE
ENSEMBLE GUIDANCE TO 25 TO 35% POPS. ALL GUIDANCE DOES POINT TO SOME
WARMER TEMPERATURES UNDER THE BUILDING RIDGE MONDAY AND TUESDAY.
