Honestly, if you've lived in the Milwaukee area long enough, you know the drill. One minute you're enjoying a relatively mild afternoon, and the next, you’re digging your car out of a snowbank. It’s Tosa life. Right now, the weather forecast Wauwatosa WI is looking like a classic Wisconsin mixed bag.
As of Thursday night, January 15, 2026, it’s a chilly 23°F outside. But let’s be real, the "feels like" is what actually matters when you're walking the dog near Hart Park. With the wind coming out of the southwest at 9 mph, it actually feels more like 12°F.
Basically, it's cold. You’re gonna want the heavy parka tonight.
What’s Actually Coming Down the Pipe
The sky is currently overcast, and we’re heading into a bit of a snowy stretch. Most people see "snow" on the app and panic-buy milk, but here’s the actual breakdown for the next couple of days.

Tonight, the low is dipping to 13°F. There’s a 32% chance of snow after dark. It’s not a blizzard, but enough to make the morning commute on North Avenue a little "interesting."
Friday, January 16, brings a high of 34°F. That sounds almost warm compared to the last few days, right? Don't get too excited. We’re looking at snow showers throughout the day and night. The chance of precipitation jumps to 35% during the day.
The Deep Freeze is Real
If you thought Friday was the worst of it, Saturday and Sunday are coming for your heating bill.

- Saturday, Jan 17: High of 20°F, low of 9°F. More snow showers.
- Sunday, Jan 18: High of 16°F, low of 3°F.
And then Monday, January 19, hits like a ton of bricks. We’re looking at a high of only 4°F and a low of 1°F. With 21 mph winds from the west, that’s the kind of cold that makes your nose hairs freeze instantly.
Staying Safe When Tosa Turns Into an Ice Box
The National Weather Service out of Sullivan is already keeping a close eye on these "clipper" storms dropping down from Canada. We just had a Winter Weather Advisory end yesterday because of flash freezing on bridges and overpasses.
When the weather forecast Wauwatosa WI predicts these swings from 34°F down to single digits, the "melt and freeze" cycle is your biggest enemy.

- Check your tires. If they're low, the cold air will make them worse.
- Salt early. Don't wait for the ice to turn into a skating rink on your sidewalk.
- The 5-1-1 Rule. Call 5-1-1 for road conditions before heading toward Mayfair Mall or the Zoo Interchange.
Is There Any Good News?
Kinda. If you’re a fan of local winter activities, the "JanBoree" is starting up nearby in Waukesha, and West Allis has their Winter Week starting January 18. If you can stomach the cold, Tosa’s outdoor dining scene is actually pretty legit. Places like Eldr + Rime have those "Stugas" (heated igloos) that make a 16°F day feel like a cozy mountain retreat.
The historical average for Wauwatosa in January is usually around 22°F, so we’re actually hovering right around normal, despite how brutal Monday looks.
Next Steps for Tosa Residents:
Keep an eye on the wind speeds for Monday, Jan 19. With 21 mph gusts and a 4°F high, frostbite can happen on exposed skin in under 30 minutes. Make sure your emergency car kit has a real blanket—not just one of those foil ones—and keep your gas tank at least half full to prevent line freeze.
