Summer outlook for Minnesota gets differing forecasts from 2 major weather outlets

Regardless, it's not winter so it's a win for Minnesota.
Publish date:

In an Old Farmers' Almanac vs. Farmer's Almanac-like battle, the summer temperature forecast for Minnesota is portrayed differently by The Weather Channel and the National Weather Service. 

In today's Weather MN blog, brought to you by Pet Evolution, we're looking at the differences that can be summed by by saying one expects a cooler summer while the other predicts a relatively standard season. 

The Weather Channel expects cooler than normal temps

"El Niño summers suggest cooler risks across the northern/central Plains with warmth favored across the Pacific Northwest," said Dr. Todd Crawford, chief meteorologist at The Weather Channel.

He says there's a lot of soil moisture in the Upper Midwest, which can have a cooling effect. 

The Weather Channel breaks its temperature trend predictions into categories: 

  • Near or slightly below average
  • Below average
  • Near or slightly above average
  • Above average

They've got all of Minnesota in for a below average June and July, followed by a near or slightly below average August. 

In Minneapolis, the average high temps in June, July and August are 79 degrees, 83 degrees and 80 degrees, respectively. Anything below those averages would lend a hand to a "below average" forecast being accurate. So it's not like it's going to be cold. It might actually be even more tolerable than normal.

The National Weather Service

On the flip side, the NWS and National Oceanic and Atmospheric Administration (NOAA) aren't as confident in cooler temperatures. Here's a map showing equal chances for above or below normal temperatures throughout Minnesota for May, June and July.

The same goes for the three-month, long-range temperature forecast for June, July and August.

"EC" on the map essentially means there is an equal 33.3% chance of having normal, below normal or above normal temperatures. 

What about precipitation?

Similar to the temperature outlook, NOAA is forecasting equal chances for normal, below normal or above normal precipitation in May, June and July for most of Minnesota. The exception, as you can see in the map below, is far southwest Minnesota, where slightly above normal precipitation is forecast.

Southwest Minnesota is fresh off one of its snowiest winters on record, with Marshall racking up an all-time record of more than 88 inches. 

Meanwhile, the long term can take a hike because temps Friday will be in the 60s statewide with bountiful sunshine, with temps soaring into the 70s on Saturday with more much-needed Vitamin D from the sun. 

Sunday looks like there could be a shower or thunderstorm late in the day, but otherwise another nice day. The NWS Twin Cities says temps could soar into the mid-to-upper 70s on Sunday from southern Minnesota up through eastern parts of the state if cloud cover ahead of an approaching front stays sparse.
