(forecast below this discussion)Cold Rain to Dominate Sunday-Monday Weather
Another Warm Day for March Yesterday
St. Cloud managed some sunshine through high clouds yesterday (see infrared loop from College of DuPage Satellite and Radar Menu), so high temperatures managed to make it into the middle 50's (see 3-day loop of high temperatures from NWS/University at Albany).
Large Storm Delayed a Bit With Snow Potential North and West of St. Cloud
Meanwhile, the major storm moved from the Southern Rockies to the Texas and Oklahoma Panhandles (see infrared loop from College of DuPage Satellite and Radar Menu). The expected torrential rainfall has produced flash flooding in southern Missouri, northwestern Arkansas, and southern Illinois with flood watches and warnings from Wisconsin and Lower Michigan to Mississippi. There has also been heavy snow in the mountains of Colorado, New Mexico, and Wyoming, spreading eastward to western South Dakota, Nebraska, Kansas and Oklahoma. Some storms from Illinois to Arkansas, Louisiana and east Texas also produced severe weather, mainly straight-line wind damage, but even a couple of tornadoes.
Today's the day that the major storm will shift northward and begin affecting us. The newest computer forecasts has slowed the northward progress of the storm, so the current rain showers in eastern Nebraska and a few places in Iowa (see NWS Upper Mississippi Valley radar loop) may not spread through southern Minnesota until midday and may not reach central Minnesota until late this afternoon or early this evening. It looks like the bulk of the precipitation will fall from late this afternoon until early tomorrow morning. However, the track of this storm is still expected to be in eastern Iowa, southwestern and central Wisconsin and perhaps even brush southeastern Minnesota. That will put the heaviest expected precipitation from southwestern Minnesota rather through central Minnesota to the St. Croix Valley. St. Cloud could be among the places that sees 1-2 inches of precipitation. But, the storm track will be far enough to the north and west to keep temperatures above freezing in Willmar, St. Cloud, Cambridge, Milaca, and Buffalo. So, I expect mostly rain with only a few sleet pellets or a wet snow flake or two.
The threat for any accumulation of frozen precipitation will be in a narrow swath from Morris through Alexandria, Fergus Falls, Bemidji, Brainerd, Moose Lake and the interior of the Arrowhead. Between 2 and 4 inches may be possible in these areas. Places like Alexandria and Little Falls will have a mixed bag developing in the middle of the storm, so it's still hard to tell how much of the precipitation may be snow or ice. Those are the areas where travel could get difficult late tonight into tomorrow. The National Weather Service has a winter weather advisory out from late evening until noon tomorrow for this swath of Minnesota from southwestern and west central Minnesota through central Minnesota to our north and then into the Arrowhead.
The strong storm will move out by late Monday or Monday night. We will see occasional rain or snow showers continue through Monday and Monday night. There could be a chance of a coating of wet snow on Monday night in areas that will remain snow-free tonight, but it won't amount to much.
Cold and Miserable Weather to Continue into Wednesday
The big issue for the next two days will again be the penetrating cold. We could eke out a high near 50 today before the clouds get too thick, but temperatures will fall back into the middle 30's tonight, then only recover to near 40, at best tomorrow. The stronger storm will create wind speeds of 15-30 MPH with higher gusts, starting today and tonight from the northeast and turning to north tomorrow and northwest tomorrow night.
The storm will drift off on Tuesday, but there could be a few weak upper-level low drifting through on both Tuesday and Wednesday. Combine that with the lingering moisture near the ground from the dousing and we could see some occasional showers those two days. Even we can dry out enough, temperatures will reach into the 50's both days.
Spring Will Spring Again Late Week
There is good news, since this storm may be the last one to have a lot of moisture with it for a while. The forecast steering winds are expected to swing further to the north, pushing through the Canadian Rockies and into the Prairie Provinces and Great Lakes. That may allow temperatures to finally moderate. It looks really warm for Nebraska, Kansas, Missouri, and points south. Here, we may have a reinforcing Canadian front or two, but the sunnier weather should at least get temperatures back to the 60's, where they should be in late April and early May.
