The Dog Days of September limp on, with a heat index in the mid-90s almost every day into Saturday. If you're heading off to the State Fair stay hydrated and take plenty of breaks. Check the blog for more details. -Todd Nelson
Summer hasn't run out of gas, not yet. Daytime highs surge into the 80s into Sunday, possibly Monday - odds are Canadian relief will stall to our northwest, keeping us on the sticky side of a front - and the northern edge of a sprawling heat wave - for roughly the next week. Great fun. A few T-storms are in the forecast, especially northern Minnesota, but with planning (and luck) you may just salvage an OK holiday weekend. On paper.
We salvaged an OK weekend after all, not as warm as we thought though. I'm still wondering (out loud) if a canopy of thick smoke from western wildfires kept us a few degrees cooler. The combination of heat and humidity will make it feel more like July this week, a streak of days ranging from 85-90F. Relief arrives next weekend; right now Sunday looks like the wetter, more volatile day. By Labor Day it will definitely feel like September.
Yesterday was a murky day, smoke from western wildfires kept our sky dirty - keeping daytime highs a few degrees cooler. A very warm week is shaping up - I hesitate calling it a heat wave, but a few days may approach or even top 90F. Meanwhile Erika is no longer a tropical storm but that doesn't mean the flood risk for Florida has passed. Not yet.
The rains pretty much avoided the metro yesterday; just a trace of rain at MSP International. Today will be sunny and lukewarm; downright hot weather returns next week with a streak of days in the 85-90F range. Meanwhile we're still keeping an eye on "Erika", which promises to deliver a memorable dousing to Florida early next week.
