Frosty weekend: And perfect TC Marathon weather

Time to cover those Super Petunas.

The first frost advisories of the year are flying this weekend across Minnesota.

A crisp, refreshing (and frosty) Canadian air mass has invaded Minnesota right on schedule for the first weekend of October. Wait...let me say that again...OCTOBER! Okay...It took a little more effort than I expected to type that word.

The deep freeze will plunge temperatures into the 20s in the northern half of Minnesota this weekend. A frosty coating will likely cover most of southern Minnesota by Sunday morning, as temps dip into the 30s.

Frost advisories include central Minnesota Saturday morning.

Freeze warnings are flying for the Iron Range and BWCAW area.

In southern Minnesota it looks like the best chance of the season's first frost will come Sunday morning.

The chilly weekend will come with mostly clear nights and sunny days.

Perfect TC Marathon weather?

If you're a runner, you may love the forecast for Sunday morning. Look for clear skies, plenty of sunshine and a crisp cool temperature in the 30s at sunrise Sunday morning.

Temperatures should warm through the 40s and into the 50s by late morning. This could be one of the best weather days ever for the Twin Cities Marathon.

Warm up next week:

All signs point to a return of mild air for Minnesota next week. Temperatures should crack the 70s once again by mid week. With the trees near peak fall color next week (and few mosquitoes after a potential frost) this could be one of the best stretches of weather of the year in Minnesota.

It may also give farmers another stretch of warm dry weather to get in the fields and collect the harvest.

70s may return next week!
