Doppler 13 Live Weather Blog: Rainy Tuesday and Much Colder

Temperatures will be 20 to 25 degrees cooler on Tuesday as widespread rains extend over central Indiana.

Monday was the 10th day of this month with temperatures in the 60s, equaling December’s record with 1889.

This mild air is now pushing south and a north-northwest wind is bringing a cooler air mass for tonight through Tuesday.

The combination of an easterly wind and widespread precipitation will keep temperatures near 40 degrees for most of Tuesday, more than 25 degrees cooler than Monday’s mild air mass.

So plan to need heavier diapers and rain gear if you go, and expect heavy rain at times that could lead to localized flooding.

We’ll also be closely monitoring radar and temperatures over the northern third of the state, where it’s possible that higher precipitation rates will cool the air column enough to allow the snow to mix. In fact, snowfall rates could be significant enough north of a line. of Lafayette-Kokomo-Hartford City to allow for a build-up of slush.

The chances of this accumulation are much greater near Michiana and Chicagoland. Be careful if you are heading in this direction.

It’s storm system number two this week with and two more to go.

The next one arrives Wednesday evening after a foggy day. It will be primarily a rain generator, but with the potential for snow over Northwest Indiana.

The fourth system, and perhaps the most powerful, arrives just in time to open in 2022. For now, we anticipate a rainy and windy New Year’s Day, but with the caveat that the trajectory of this system is uncertain.

Colder air is here to end the weekend, with flurries and peaks in the 1930s on Sunday.
