Aug-tember continues this week

Highs in the 80s linger

Share story

Spring in Minnesota came late this year. Summer seems intent on loitering through most of September. 

Our Wednesday morning rain bands produced some impressive rainfall totals across the state — 24-hour rainfall totals exceed 2 inches at Mora, Sartell, and Winton near Ely. Several locations picked up an inch or more.

Slow-moving cool front

Our inbound cool front takes its sweet time moving through Wednesday. Another band of showers and storms will fire along the front Wednesday evening. The National Oceanic and Atmospheric Administration’s NAM 3 km resolution model shows the front refiring around 7 p.m. and pushing storms south into Iowa overnight.

Summer lingers

Forecast model guidance is like a weather slot machine that keeps cranking out summery 7s.  The weather numbers continue to suggest mild temperatures will linger into next week.

The upper-air maps suggest a brief cooler intrusion early next week, followed by another warm spell.

One thing we know for sure in Minnesota? Fall will get here. Eventually. NOAA’s eight- to 14-day outlook favors above-average temperatures overall through late September.
