71 degree high at MSP at 11:49am Tuesday.

(Coolest high temps in 68 days since June 25th when it was 68 degrees!)

66 degrees with drizzle by 5pm Tuesday

77 average high temp for August 30th

96 degrees possible Thursday in the metro and southern Minnesota!

48 degrees in the metro & suburbs by Labor Day morning?

40 to 50 degree temp swing in parts of Minnesota in 72+ hours?

Scattered frost near Ely by Labor Day?

It’s that time of year again. A “high amplitude” jet stream pattern will bring some rather dramatic weather changes to Minnesota in the next week, and beyond.

What meteorologists refer to as a “push-pull” weather pattern will bring a series of warm and cold front through Minnesota. This time of year, there’s still plenty of warm summery air to the south, and developing cold air to the north.

As low pressure systems swing through, cold air is pushed in behind, then warm air is pulled up ahead of the next system.

Mid 90s Thursday?

That sets us up for some big weather changes in the next month, with potentially dramatic and extreme temperatures swings.

Only in Minnesota can you go from coconut oil to polar fleece in 72 hours!

Foggy start; then sun returns today:

Labor Day Weekend weather shocker: Fall like cold front still on track?

This may be a shock to the system.

After we’ve bathed in warmer than average temps for the past 3 months, it looks like temperatures may crash this weekend on gusty northwest winds.

Forecast models develop a potent looking low pressure system will develop right over Minnesota this weekend. That means a likely shot of rain, and the season’s first strong late summer (early meteorological fall!) cold front will slam south by Sunday.

Saturday night into Sunday is looking wet, windy and raw at this point, with highs only in the 60s and a gusty northwest wind making it feel like….gulp…50s up north?

With lows in the 40s by Labor Day morning, some parts of Minnesota may literally go from AC to heat in just over 72 hours.

Katia reaching hurricane force:

Tropical Storm Katia should become “Hurricane Katia” today.

The latest hurricane “spaghetti tracks” still steer Katia out to sea east of the USA in about 10 days.

    So does this mean my planned trip to the fair on Friday afternoon may be rained/stormed out?

  • Rich Reardon

    Looks like we’ll crack a 70 dewpoint today and likely again tomorrow.

    Question for you, Paul.

    How many days this summer have we had a 70 or higher dewpoint, and how does that number of days compare to average?

    I can’t seem to tease this data out of the NOAA site.

    Thanks.
