We hit hard freeze criteria in a lot of northern Wisconsin, effectively bringing an end to the growing season up there.

A hard freeze is defined as when the temperature gets down to 28°F or lower for at least an hour.

Top-10 lowest temperatures in Wisconsin on October 8. Temperatures range between 22 and 27 degrees.

Nice fall weather today, so we’re getting a lot of work done.

Weather radar lets us see more than just precipitation!

When large groups of birds and bats take off, they can create roost rings as they spread out into the air.

We can also see masses of insects flying around, wind farms, and even transportation.

Which do you see in this radar loop?

Freeze Warnings and Frost Advisories are in effect for most of the northern part of Wisconsin tonight into tomorrow morning.

This is our first big shot of cold air this fall, so if you still have plants you want to keep for a little longer, here's your notice to cover them up or bring them in!

And they go on to build a weather station network, or so we hear.

As expected, the Freeze Watch is now in effect for all of northern Wisconsin for Tuesday evening - Wednesday morning.

If you have sensitive plants that you'd like to keep around for a little longer, make sure you cover them or bring them inside!

A Freeze Watch has just been issued for northeastern Wisconsin, for the possibility of temperatures in the upper-20s to lower-30s Tuesday evening and Wednesday morning.

It would not be surprising to see this get expanded across most of the rest of northern Wisconsin.

The storm system that produced this tornado eventually made it to Wisconsin and we measured a 78 mph wind gust at 3-meters in Bayfield.

Did you know that we have a Wisconet station just 1 mile away from the New Berlin Public Library?

Check out some books and then check the weather!

A doozy* of a cold front moving through Wisconsin, with temperatures up to 30 degrees lower than they were this time yesterday on the back side of it!

In Grantsburg, it's only 39° right now - 37 degrees lower than yesterday's high of 76°!

* Relatively a doozy. This isn't fully ushering in fall.

A bit cooler today than it was yesterday, but it is also quite breezy.

All-in-all, a nice fall afternoon, so get out there and enjoy it.

Watch out for the Gales of October!

There is a Gale Watch for the American waters of Lake Superior from Sunday morning until Sunday night.

Strong wind gusts up to 45 mph and large waves will make boating conditions hazardous.

You don’t need widespread storms to get a lot of rain, but you do need widespread rain gauge networks to measure the rain.

Our Black Creek station picked up 1.38“ of rain last night from a couple small storms.

If the storms had moved just a little south, we wouldn’t have direct measurements.

Radar showing a few small scattered storms.

Rain accumulation over a couple hours added up to 1.38”.

It's up to 15 degrees warmer right now than it was 24 hours ago.

Mid- to upper-80s for highs the next couple days...will any of our stations hit 90°?

I sure hope not...

Probably not a big surprise to see an expansion of Abnormally Dry conditions on this week's Drought Monitor, given the warm and dry end to September that we saw.

New tool alert! Hopefully this gets us thinking about the cool weather that we're still waiting to arrive.

Look, Midwest vs. Everybody, we wish we didn’t have to talk about the heat in October, but we’re ready for fall.

The last monthly temperature outlook for October before it begins tomorrow.

60-70% chance of above normal temperatures across the Great Lakes region.

Fall is going to keep waiting to show up.

Dear atmosphere, it's September 29.

We don't need it to be in the mid-80s on the shore of Lake Superior. We don't need it to be almost 90 in southeastern Wisconsin.

We want cool, crisp mornings, mild afternoons, and partly cloudy skies.

Summer is over. Act like it. 🥵
