KEY MESSAGES

- A cold front's early morning passage will sweep in a blast of arctic cold air today, with temperatures falling to near and below freezing.

- A reinforcing shot of arctic cold will come with another cold front's passage Tuesday. While a dusting of snowfall is possible with its passage in the Evansville Tri-State region, its main impact will be the cold air reinforcement. The coldest readings will be late Tuesday night into early Wednesday morning, when temperatures and wind chills bottom out in the lower single digits (north) to teens (south).

DISCUSSION

Issued at 130 AM CST Mon Jan 13 2025

A cold front is currently making its passage, bisecting the FA at this writing. It will drop temperatures below freezing, where they'll remain even during the day with clearing/return of sunshine. The lone exception may be the SEMO Ozarks, which subtly rebound/hover in the lower half 30s.

A reinforcing blast of arctic cold comes with another frontal passage Tuesday. While moisture starved, the deterministic modeling still hints that its dynamical energy may squeeze out what little moisture there is with some slight chance light snow showers. Even one hundredth of liquid qpf may produce about 2 tenths of an inch of snowfall in our far northeast, where LSR's will run almost 20 to 1.

The main impact with the frontal passages will be the cold. Lows tonight in the teens will fall into the single digits in our north the ensuing night (Tuesday night), and minimum wind chills both tonight and Tuesday night will range from the lower single digits (north) to teens (south).

The arctic high pressure/air mass will translate to the east by Thursday, as heights rebound in the wake of the departing upper trof responsible for the cold. That's when we'll see the mercury rise above freezing again, as we transition toward a more seasonal mid January temperature profile. Highs in the 40s return by week's end, but another plunge of cold air will come with a weekend frontal passage. It'll draw temps down below freezing again, where they'll stay for the start of the new week.
