We've been hearing so much about the debilitating heat gripping much of the USA, the epicenter of pain over the southwestern states. There is no sign of that heat sweeping into Minnesota anytime soon. In fact I see a continued cool bias for the next 2 weeks, no prolonged warming trend (80s or hotter for days on end) until maybe the second week of July at the earliest. We're making up for a very warm start to June, it seems. Details on Cindy, which has weakened, but continues to threaten much of the Mid South and Ohio Valley with flooding rains.
Lingering showers and storms work through southern Minnesota today before more sun returns Friday. Hot & sticky weather will resume in July, it always does. Check the blog for more details. -Todd Nelson
Spotty late day storms bubble up across southern Minnesota Wednesday, some of which could be a little strong. Cool exhaust on the back side of this system brings temps well below average for the upcoming weekend. Some will have a tough time reaching 70 degrees. Check the blog for more details. -Todd Nelson
It may be a few degrees too cool for the lake or pool yesterday, but I have trouble working up righteous indignation about low to mid 70s, blue sky and low humidity. Free Canadian A/C will be the rule into much of next week, while much of America sizzles, and residents of the Gulf Coast keep an eye out for serious flooding. Details in the blog.
Sunday wasn't bad at all, a little on the cool side but I didn't hear many complaints, in spite of the light showers and sprinkles that bubbled up. A stray shower is possible later today as temperatures continue 5-10F cooler than average. Making up for a warm start to June. We're watching a possible tropical system in the Gulf of Mexico - details in the blog.
