Major Frost Potential Tonight

We've now had a full day of the average October temperatures, which were much cooler (see 14-day St. Cloud temperature graph from MesoWest). There was plenty of sunshine(see College of DuPage North America clean infrared satellite loop) as the leftover clouds near the upper-air low pressure system (see College of DuPage North America water vapor loop) began to dissipate. That has set up a partly clear (see College of DuPage North America shortwave IR loop) and calm nigh in a small strip of central Minnesota, so temperatures have fallen into the 30's (see NWS Aviation Weather Center METAR menu). There is a slight chance for a frost near sunrise this morning.

Since the upper-air low is moving eastward, there will be fewer clouds today and tonight, so there is a better chance for sub-freezing temperatures. The National Weather service has freeze warnings for northern and parts of central Minnesota tonight, since lows in the 20's are likely in these areas. There is a frost advisory in central Minnesota, which includes St. Cloud. So, today is the day to get those delicate plants inside.

Otherwise, the cooler weather will be quiet. High temperatures will continue in the 60's today, push into the upper 60's tomorrow, and range from the upper 60's to the lower 70's Thursday and Friday. The overnights won't be quite as cool with low temperatures generally in the 40's. There will be a small chance for a Thursday shower (1 in 5) as a weak cold front comes through.

This weekend, we should be a bit warmer with highs in the 70's. There will be a significant, but uncertain chance for showers from Sunday afternoon into early next week. There will be a strong low pushing from the eastern Pacific slowly into the Northern Rockies over the weekend. That will push a cold front into Minnesota during the second half of Sunday. Then, the front will linger in the Minnesota area early next week. That will produce an uncertain chance for showers and make temperature prediction very difficult.
