Quieter and Cold Through the Weekend
Light Snow and Ice Leaves Slippery Roads in Southern Minnesota
While the St. Cloud area had merely a few snow flurries yesterday morning, there were 1.3 inches of accumulation at Minneapolis-St. Paul International Airport, 1.0 inch at Lutsen, 0.5 inch at Duluth, 0.2 inch at Eau Claire, and 0.2 inch at Rochester. In Rochester, it was a combination of snow and freezing rain. There have been as much as 3 inches in north central Wisconsin. The Minnesota Department of Transportation road reports show only some snow on the roads in a few parts of southwest Minnesota. Since temperatures have fallen back below freezing statewide, watch out for icy spots on untreated roads as you head out this morning.
All of the precipitation from this storm system has moved out of Minnesota as of 2 AM (see NWS
Upper Mississippi Valley radar loop) and skies have been clearing (see infrared loop from College
of DuPage Satellite and Radar Menu). That has allowed temperatures to fall to 20 degrees or colder in the northern two-thirds of Minnesota (see NWS
Aviation Center Minnesota map). The stubborn northwest wind has dropped wind chills down to the single digits above zero in most of central Minnesota (see NWS
Minnesota Hourly Weather Round-Up). There are even a few sub-zero wind chills in northwestern Minnesota.
Return of Sunshine Today
As promised, the weather will now quiet down for the rest of the weekend. Temperatures will remain on the cold side, as I only expect high temperatures in the 20's today, around 30 tomorrow, and in the low to middle 30's on Sunday. Low temperatures will again drop into the teens the next two nights. The main good news is that, after today, the winds will drop off, so the seasonably cold temperatures won't feel as bitter as they are this morning.
Early Week Storm??
Minnesota's next big forecast question is where the large storm dominating the west (see counterclockwise circulation on the infrared loop from College
of DuPage Satellite and Radar Menu) ends up going. The past few computer runs had taken this system to our west early next week, but the new information tracks this storm just to the south of Minnesota Monday night and Tuesday. That would be a favorable track for accumulating snow in Minnesota and the Dakotas, but that is still 4 days down the road. We've seen in the past week how a general storm forecast has or has not worked out 5-7 days in advance.
So, I'll keep watching the evolution of this system in the forecasts and updating this site.
As the front continues to push southward, there is a threat today of major ice accumulation across western Oklahoma and the Texas Panhandle with more icing problems in eastern Kansas and western Missouri. There could be enough ice accumulation to down trees and power lines. Further to the east, the heavy rains will continue with a risk of flooding from southern Missouri into Texas. This rain could slow down air traffic in Detroit, Chicago, and Dallas-Ft. Worth today (see FlightAware.com delays map)
