Central Indiana undergoing some significant weather swings this week and it began with a Monday midnight high of 61° that's been replaced with wind chills in the single digits/teens, making it "feel" some 45° colder than 24 hours ago.
Live Doppler 13 Radar is quiet tonight and will be much of Tuesday despite a rather cloudy sky. With that said, some flurries or a snow shower are possible. The bigger story during daylight hours Tuesday will be unseasonably cold highs in the 20s — the coldest since mid-February.
An upper disturbance moving across central Indiana later Tuesday will squeeze-out any moisture it can and that results in flurries and light snow. Some accumulation is possible with localized amounts of a half-inch to an inch. But latest guidance suggests that may be the exception and not the rule.
We'll reassess Tuesday afternoon for any potential of slick spots for the Wednesday morning. This will be a blip on the radar though with another significant December warm-up on deck later this week.
Modeling has been very consistent on an anomalously strong storm system developing to our west, strengthening, and then tracking into the Great Lakes Friday into Saturday. This would place central Indiana in its warm sector and within air mass capable of rivaling daily record highs Friday/Saturday.
In addition, its dynamic wind field in combination with increasing low-level moisture would put severe storms in play. We'll narrow down specific local impacts in the days ahead.
