Major storm to impact southern Wisconsin

• A Quiet, But Cloudy Day Today
• Rain Develops Later Tuesday
• Rain Likely Through Wednesday

MADISON, Wis. (WMTV) - Today’s weather will be similar to what we had during the weekend: overcast skies, temperatures starting around freezing in the morning and warming to the mid-30s by the afternoon. No precipitation is anticipated though.

We’re closely watching our next system, and some of the pieces of the forecast picture are starting to come together. Low pressure will be moving out of Colorado, carrying a lot of moisture into the Midwest. This will be a very slow-moving system, we’ll see impacts from it for at least 3 days. Temperatures will also play a key role in the type of precipitation we see and when.

Locally, it looks like rain will begin to move in during the second half of Tuesday as a few sprinkles and light showers. The intensity level of the rain will increase through Tuesday night and into Wednesday. Wind will also be on the increase and will become quite gusty by tomorrow through Wednesday. Highs on Wednesday will be in the lower to middle 40s, but as this system slowly slides to our east on Thursday we’ll see some cooler air start to move in. I would expect to see a transition from rain to snow on Thursday, with the chance for some snow showers to linger into Friday.

When we see that switch from rain to snow will really determine how large of an impact this system will have on southern Wisconsin, so stay tuned to the forecast as we continue to iron out the details.
