Our quiet and mild stretch of weather will come to an end this upcoming weekend. Highs will return to the upper 80s with storm chances both Saturday and Sunday.
The first rain chance for SE MN and NE IA will be late Thursday night into early Friday morning. Showers and storms will stay scattered and isolated into early Friday morning. Current model guidance suggests a 2-5 a.m time-frame for showers. Rainfall accumulations should stay under a tenth of an inch. Skies will slowly clear through the afternoon Friday with partly cloudy conditions. Highs will warm into the upper 70s and lower 80s Friday.
Another round of showers and storms will be possible late Friday night into Saturday morning. This round could bring heavier rain with some thunder and lightning. Severe weather is not expected Friday night through Saturday morning.
Sunday appears to be the day with the "best chance" of stronger storms in Minnesota and Iowa. Temperatures will warm into the middle and upper 80s with dew points in the upper 60s and even lower 70s. A cold front will sweep across Minnesota and Iowa during the afternoon and evening. This could provide the lift needed for thunderstorm development. Moving forward, we'll keep a close eye on Sunday afternoon and evening for thunderstorm chances.
