How Low Can We Go Without Snow

Teens for the Second Half of This Week

The cold front just passed through central Minnesota in the early morning hours (see 24-hour loop of NWS WPC US surface maps). With the low pressure system drifting into northwestern Minnesota, however, the colder air has to take the scenic route around the western and southern flanks of the low. In the early morning hours, temperatures were falling through the 20's in west central and central Minnesota (see UCAR Minnesota surface chart), but there are teens upwind of us in central and eastern South Dakota. Note also that the winds have cranked up to speeds of 20-25 MPH with gusts of 35-45 MPH. Those winds are working their way into west central Minnesota and will move in here by sunrise (see latest winds and gusts on the NWS Minnesota Hourly Weather Round-Up).

The bulk of the snow has remained over North Dakota and northwestern Minnesota (see NWS Upper Mississippi Valley radar loop), with Grand Forks receiving nearly 9 inches of new snow by 2 AM. All of that snow, combined with the increasing winds, has led the National Weather Service to issue a blizzard warning from most of North Dakota into the Red River Valley portion of northwestern Minnesota. Expect major travel problems today in northwestern Minnesota (see MnDOT Minnesota road conditions) and all of North Dakota (I-94 is already closed from Jamestown to Dickinson with no travel advised in the western two-thirds of the state). There is a winter weather advisory from Stearns County westward for areas of limited visibility in periods of falling and blowing snow.

As the upper air low comes through Minnesota today, we could see some occasional light snow or flurries, but the main snow band between Devils Lake and the Red River Valley will stay well to our north. We might pick up a light coating of snow. The main problem will be low visibility due to blowing snow during any snow shower. Temperatures are going to stay in the 20's during the day.

The winds will ease up a little on Thursday, blowing at 10-20 MPH. We will have a lot of clouds, but could see some sunny periods as well. Highs will remain near 20 on Thursday. The winds will ease off enough to allow a partly clear and calm night Thursday night. We may not get below zero without much snow cover, but we should see lows in the single digits to near zero for this first time this season. The lighter winds will make Friday's highs in the teens feel a bit more comfortable than the next 2 days.

We will remain in the leftover cold air through the weekend, but there is a chance for some light snow or flurries as a weak storm system slides along the front to our south. We could see a little bit of light snow on Friday night into Saturday, then there is a potentially stronger storm due to move to our south for Saturday into Saturday night. That system could spread more significant snow (3-6 inches?) across southern and perhaps central Minnesota late Saturday and Saturday night.

Cold Weather Safety

You may want to review the winter safety checklists in the National Weather Service cold weather safety page. Even though the temperatures and wind chills won't reach dangerous levels, this would be a good time to make sure your vehicle is prepared for the colder season. It certainly won't be comfortable to get stuck in the coming weather.

Again, travel will be difficult if not impossible from the Red River Valley into North Dakota today (see MnDOT Minnesota road conditions).
