Hope you enjoyed the good sleeping weather overnight Wednesday.
Because an a/c revival will be necessary Thursday, as the humidity cranks up alongside summer-like temperatures in what KSTP Meteorologist Ken Barlow says could be summer's last gasp.
Temps on the last full day of summer are expected to reach into the lower-80s. When fall officially arrives at 3:02 p.m. Friday, temperatures in the Twin Cities will be 90 or more and dew points will be in the upper 60s to lower 70s on the back of a strengthened low-level jet stream. In a word, Friday will be steamy.
As hard as it is to believe, the heat index will be 100 when autumn arrives at 3:02 pm Fri. Those planning outdoor activities, use caution! pic.twitter.com/wit5JmRzxJ— NWS Twin Cities (@NWSTwinCities) September 21, 2017
The National Weather Service is reporting a slight risk of severe weather that could carry high winds and hail after 5 p.m. Friday in portions of western Minnesota.
Low temps in Twin Cities are forecast to be 70°+ next 3 nights. This would be record for latest consecutive 70° low temps this late in year. pic.twitter.com/06koltqaqi— NWS Twin Cities (@NWSTwinCities) September 21, 2017
After Friday, the weekend looks to get wet. Barlow says temps will drop a bit on Saturday, but the humidity will stick around. Thunderstorms could come into play Saturday afternoon and evening, and the will likely continue through at least Sunday, though less-so in the Twin Cities.
The weather service says the greatest potential for significant rainfall this weekend is in the western and central portions of the state, and that the potential for severe weather after Friday will be diminished.
