Snow Possible For Some Tonight

Sunshine continues across the I-70 corridor… for now.  Clouds will increase late afternoon as an approaching weather system embarks on the Ohio Valley.

No big changes to our ongoing forecast.  There’s still a “chance” of “light” snow over parts of Central Indiana between the hours of 8pm-3am (give or take).

FutureTrak 13 at 7pm shows a narrow sliver of possibly flurries/light snow entering western Indiana.  This seems feasible when you project out a band light snow that’s currently in Iowa.  It’s still difficult to say how much will actually be able to reach the ground, due to very dry air at the surface.

Warmer surface temps from I-70 southward, the precip may initially begin as rain before transitioning to all snow.  This region will have better atmospheric lift and moisture to produce precipitation, but a warmer ground should allow any snow to melt quickly.

Though I don’t anticipate “widespread” road issues, if the aforementioned sliver of snow materializes a light accumulation is possible… especially north of I-70 given the colder temperature profile there.

Also of note, a persistent northerly wind vector off of Lake Michigan may push some lake effect flurries/snow showers into the northern viewing area… and possibly as far south as the 465 loop Tuesday morning.   This will require some nowcasting, with low confidence in that part of the forecast.
Tuesday will be unseasonably cold and leads into a frosty start in the low/mid 20s Wednesday morning.  Each day will get progressively warmer heading into the weekend.  Temperatures will approach 60° for the start of December!
Have a great afternoon.
