Warmer again by next week?

It doesn’t look like the cold air wants to stick around so far this fall.

Models from the European Centre for Medium-Range Weather Forecasts and the National Oceanic and Atmospheric Administration’s Global Forecast System both suggest warmer air will return to Minnesota next week. Highs will rise through the 60s Monday afternoon in the south.

But forecast models suggest 70s will return to at least southern Minnesota next week.

NOAA’s Global Forecast System model and the agency’s three to four week outlook both suggest warmth could linger well into October this year.
