Adios, summer weather: Friday likely the year's final 70-degree day

If you're looking for weather that gets above that 70-degree mark after tomorrow, you may need to plan a trip south.

MPR's Paul Huttner says on his Updraft blog that Friday afternoon could be the last time many Minnesotans see a 70-degree day this year. The Twin Cities is included in that group. says the high in Minneapolis is expected to hit exactly 70 degrees Friday, staying mostly sunny throughout with light 5-10 mph winds. The Friday forecast is nearly identical in St. Cloud and Moorhead, but the highs there may creep up a degree or two above the Twin Cities area.

Duluth might just miss out, with clear sunny skies but a high of 68 degrees. In Rochester, fog and clouds are expected to keep high temps in the mid-60s.

But even if the 70-degree days migrate south for the season, that doesn't mean you'll need fur hats, fleece-lined jackets and thermal underwear next week.

Jerrid Sebesta says there is still plenty of "really solid fall weather" ahead, including this weekend and next week.

"This is probably our final 70-degree temperature of the year," he says. "However, it looks like we'll still see plenty of nice fall-like days left this month with highs in the 50s and 60s."

And that's pretty normal for this time of the year.

"Once we get into November, the statistical chances of seeing 70 degrees goes down pretty quickly as average highs drop into the upper 40s Nov. 2. Record highs even drop into the 60s by Nov. 10."

According to Sebesta, a cool-down could be coming for the end of next week, making for chilly trick-or-treating on Halloween night. But that may bounce back up.

"Models continue to indicate our weather will come from the Pacific Ocean, keeping Minnesota temperatures at or slightly above average into the first few days of November," he says.

Global temperatures rise

Earlier this week, the National Oceanic and Atmospheric Administration released its Global Analysis for September of 2014.

What did it find? The average global temperature – land and ocean surface – has risen each of the past 355 months now, the Washington Post explains. For nearly 10 years now, the average temperature in a month was higher than the month prior.

Focusing in on Minnesota, the NOAA found the state's September temperatures were a little bit warmer than average – but not as dramatic as many other spots around the globe. And in nearby states – specifically Wisconsin, Iowa and Illinois – the month's temperatures were actually cooler than average. Here's the map the NOAA released.

There's also a year-to-date look, which bathes Minnesota in the colder-than-normal color of blue:

Still, the survey found this was the warmest global September since record-keeping began 135 years ago.
