An early freeze?

The coldest air of the season will be flowing into the region Friday and Friday night, and some areas could experience freezing temperatures by Saturday morning!

We're forecasting a low of 34° in Saginaw and Flint, but some rural locations away from the warming influence of Lake Huron and Saginaw Bay could drop below freezing for a low temperature.

If a freeze were to occur in these areas, it would happen 2-3 weeks ahead of schedule according to the dates shown in image 1.

The reason for the cold snap: A strong, northerly flow between a big trough of low pressure over southeastern Canada and a ridge of high pressure in the northern Plains states (image 2).

In fact, this northerly flow will be cold enough to produce some lake-effect rain showers over portions of Mid-Michigan late tonight and Friday morning.

This cold snap, however, won't last.

After a seasonably cool weekend with highs in the middle to upper 60s, highs in the 70s and 80s will return next week.
