Brilliant Saturday, Severe Sunday?

Satellite update as of noon, Saturday. Last night's showery front is kicking up rain (and lightning) in the Chicago area, potentially interfering with flights at O'Hare and Midway. A bubble of Canadian high pressure treats Minnesota to brilliant sunshine, a fresh breeze, low humidity, and temperatures close to average for late May.

Sunday will be a different story - a warm southwesterly wind (gusting to 30 mph) will lure temperatures well into the 80s, it will finally feel like summer out there again. But with the warmth, gusty winds and rising humidity levels will come a slight risk of severe storms. The SPC has most of central and southern Minnesota in a "slight risk" of severe storms. If you're heading out on the lake Sunday stay alert, tune in a local radio station, keep scanning the sky for towering thunderheads off on the western horizon, and be ready to head to shore in a hurry!

Weather Headlines

* Dry May for much of MN, especially southeastern and east central counties, potentially the driest since 1934. Third driest on record for many counties south/east of St. Cloud.
