For once it appears the timing is working out right.
Rain chances will linger through Friday in Minnesota. A Pacific front will drag a band of showers through Minnesota Friday. The showers will favor western Minnesota early Friday and move into eastern Minnesota Friday later on the afternoon and evening.
There may be a few thundershowers as the front moves through later Friday, but it appears any severe weather will likely be south of Minnesota.
A few showers may linger in eastern Minnesota overnight into the wee hours of Saturday morning, before the front sweeps the clouds away early Saturday. The sun should emerge this weekend, and that will help temperatures respond to around 70 in the south Saturday. Sunday may be the warmest day of the next week, with temps pushing well into the 70s in the metro.
Rainfall Friday may fall into the .25″ to .50″ range for much of Minnesota.
Enjoy what looks like a classic and beautiful September weekend for all outdoor activities.
