Bitterly cold Arctic air continues to blow into the region today in the wake of the potent cold front that swept through the Upper Mississippi Valley late Wednesday, keeping wind chill values at dangerously cold levels. We'll have plenty of bright sunshine for our Thursday as high pressure approaches from the northwest, but don't look for much of a warm-up thanks to the onslaught of that frigid air mass. While winds will gradually diminish through the day, wind chill values won't improve much, only "warming" from the -30 range to around -20 in the afternoon and high temperatures will be a few degrees below zero in most of the area. A Wind Chill Advisory will be in effect until noon for most of the entire region.
Clear skies and light winds will be the rule tonight thanks to that strong area of high pressure settling in from Canada, setting the stage for perhaps the coldest night of the entire winter. Overnight low temperatures tonight will be in the -15 to -20 range with wind chill values again in the -20 to -30 range.
Warmer air will, fortunately, begin to work its way into the area first thing Friday morning on the backside of that high pressure as south winds will work with abundant sunshine to push temperatures into positive territory by lunchtime. Those south winds will get rather gusty in the afternoon, occasionally reaching 30 miles per hour helping temperatures warm into the lower teens by Friday evening. Wind chills, however, won't be as warm thanks to the gusty nature of those wind, so it will still feel like it's a little below zero through most of the day.
A clipper type storm system will graze the area to the north early Saturday, bringing a few light snow showers to the Upper Mississippi Valley, but little if any accumulation is expected for our part of the region. We'll have brisk west winds and then some sunshine for the midday and afternoon with temperatures hovering near 30 degrees.
Sunday is looking a bit quieter with sunshine and lighter winds during the day and high temperatures will be in the seasonable 20s, but clouds will thicken in the evening as a storm system approaches from the west. Look for some light snow late Sunday night and Monday with some accumulation possible. High temperatures Monday will be in the lower 30s, but the remainder of the week will feature highs in the teens and 20s.
