Milder days ahead
Milder breezes blow again as we head toward the weekend. Highs return to the upper 70s to near 80 degrees over the next week. The average high for the Twin Cities Friday is 79 degrees.
Rain chances Friday and Saturday
Forecast models are still in flux with the timing of showers and T-Storms Friday and Saturday.
The latest trends suggest a slightly drier forecast, with a couple rounds of showers and T-Storms late Friday and again Saturday. Honestly, there's a lot of models spread Friday through Sunday. NOAA's GFS model seems confused to me. I'm leaning more toward the Canadian model which suggests scattered, occasional rain Friday and Saturday, with a drying trend more likely for Father's Day. But forecast confidence is low.
Here's the Canadian model from Friday through Sunday.
The Canadian model suggests rainfall totals of an inch across northern Minnesota, with lower amounts as you move south.
Midwest: Ground zero for heavier rainfall
The data clearly shows Minnesota is getting wetter as our climate shifts. But this map really jumps out. An analysis of precipitation trends over the past century shows that Minnesota and the Upper Midwest are ground zero for changes toward a wetter climate.
