Milder Weekend, Colder Early Next Week
Cold Evening, Potential Light Snow Today
Yesterday morning's light, fluffy snow did slicken some roads during the morning commute. The St. Cloud Airport picked up 0.9 inch, while I measured 1.7 inch at SCSU. The system that produced that morning snow has quickly pushed into Lake Michigan and southern Ontario (see infrared loop from College
of DuPage Satellite and Radar Menu). The clearing behind this system allowed sunshine yesterday afternoon, but has allowed temperatures to plunge overnight. Temperatures in the early morning were hovering around zero in much of central Minnesota (see NWS
Aviation Center Minnesota map). Note, however, in western Minnesota that temperatures have climbed back into the teens with a light southeast wind. That's because the next storm system, pulling its warm front along, has pushed its clouds across the Dakotas.
This weather system will again produce a chance of a little light snow or flurries. I think that today's shot of snow will only be able to produce a few tenths of an inch at most. The warmer air moving over top of the colder air will allow temperatures to climb back into the middle or upper 20's this afternoon.
Another Cold Night, Another Warm Up Saturday
Skies will clear out tonight, so temperatures will drop off once again. It won't be quite as cold as this morning, with readings bottoming out around 10 degrees or in the upper single digits.
Snow Chances Saturday Night into Sunday
A more potent low pressure system will move from the West Coast into the Northern Plains by Sunday, repeating the pattern of a warm up that will last most of the weekend. After tomorrow's cold start, we will have a lot of clouds with maybe a flurry. Temperatures will climb into the middle or even upper 20's. The mild conditions will continue tomorrow night with low temperatures holding in the 20's. Since this storm will be a bit more potent, we could end up seeing an inch or two of snow tomorrow night into early Sunday. There is a chance that temperatures could break the freezing point just before the cold front comes through on Sunday afternoon.
Colder, But Not Severely Cold Early Next Week
The advertised colder air push will begin late Sunday. However, the good news is that recent forecasts are shunting the coldest of the cold air further to the east over the Great Lakes. This means we will see more of a glancing blow from this shot of cold air. Temperatures will fall back to the lower teens by Monday morning with a strong northwest wind. Temperatures will level out around 10 degrees Monday morning, then hang in the lower teens the rest of the day. The northwest winds will continue to be strong, producing wind chills in the -15 to zero range. Temperatures will drop again Monday night, likely ending up in the minus single digits on Tuesday. However, the winds may ease off late Monday night, so Tuesday's wind chills may not be that bad. Look for highs of around 10 degrees on Tuesday.
We will generally be on the edge of the cold air by the middle of next week, which makes forecasting difficult. The good news is that the core of the coldest air in North America is due to come southward later next week, but it appears to be on a course over Ontario, Quebec, the Northeast, and the Mid-Atlantic states. If that holds up, we will most likely continue with seasonably cold temperatures.
There is the potential for more major East Coast weather with the cold surges and the possibility of another snowstorm in the middle of next week.
