A warm weekend; Chance of scattered showers & thunderstorms

June heat wave began on this date in 2021

Our current temps would be warm for July, but they are especially warm for early June.

The average June 3 Twin Cities high temperature is 75 degrees. Parts of the metro area could touch 90 degrees at some point Saturday afternoon.

Much of Minnesota and western Wisconsin will have Saturday highs in the upper 80s to around 90. There will be some 70s near Lake Superior, with a few spots up there topping out in the upper 60s.

Sunday highs reach the lower 90s in far northwestern Minnesota plus much of the southern half of Minnesota:

Rain chances

An isolated shower is possible Saturday morning, then better rain chances develop with the heating of the day.

Scattered showers and thunderstorms are expected to develop over portions of Minnesota and western Wisconsin as we go through Saturday afternoon, and some of those showers and thunderstorms could linger into Saturday evening.

Some spots in Minnesota and western Wisconsin will see little or no rain today, while other spots could see downpours at times. Remember that it does not have to be raining at your location for lightning to strike nearby.

Two years ago today, the Twin Cities high temperature was 91 degrees. Twin Cities highs were also in the 90s the following 8 days.

According to the Minnesota State Climatology Office:

“…this heat wave produced nine consecutive high temperatures of at least 90 F,  tying it for the third-longest such streak on record, and easily breaking the record for consecutive 90-degree days occurring on or before June 15; the previous record had been six, occurring in  2018, 1956, and 1934. The Twin Cities also experienced nine straight low temperatures of at least 70 F, which ranked #3 all-time and obliterated the old early-season (June 15 or earlier) records; the area had never previously recorded more than three straight 70-degree nights during or before the first half of June!

Here are some high temps and low temps during the June 2021 heat wave, with new record high temps and record warm low temps in bold:
