It’s fall. We know it, and some of us love it. One thing we all know comes with fall in Minneapolis is cold weather, and that’s unfortunately what is on its way.
I still remember the Halloween Blizzard of ’91, as I’m sure many of you do. There was a lot of snow (understatement – it was the all-time record for Minneapolis (28.4″ of snow as measured at the airport – click here for more).
The nice thing is that your Halloween forecast looks dry and sunny. Unfortunately, it looks chilly also.
If you look at the 7-day forecast above, you’ll notice the upper 20s for lows. That means if your plants have survived so far, they likely won’t survive past Halloween. Plan on picking your tomatoes (if you have them) before Friday morning! Essentially, one wave of cold air is enough to push us back now to near-average temps (Minneapolis/St. Paul average high for today is 53 degrees), and the next pushes us to below-freezing overnight lows. Here is what the computer model forecasts look like:
Those colors really are all you need to see. The temps they represent are those about 1 mile up in the atmosphere, and they are COLD. The purple shades close to Duluth represent -8 to -10 degree Celsius temps, which translate to about 14 degrees Fahrenheit. Yikes.
Thankfully there is a bigger warm-up on the way. By Sunday we kick out the blues and purples and get some greens back overhead. What does that mean? Possibly some 60s or near-60s for highs on Sunday.
Stay warm this week!
