Cool Snap a Brief One, 70s, Storms Ahead


Monday's chill sure came as a shock to the system! Following Sunday's 76° high temperature, a potent cold front swept in from Lake Michigan and sent temperatures spiraling downward! The temperature plunge didn't end until we reached a 36° low temperature Monday morning with wind chill values in the 20s! Monday's 47° high temperature wasn't much better! It goes down as the coldest temperature here since March 9th, and the first day below normal in three weeks! The long layoff between below normal days is likely why many have been up in arms about the chill! The 47° temperature, while a stark contrast to the 80s of last week, is only a level 5° below normal!

It's hardly unheard of to have this kind of chill take up residence here this time of year. In fact, it's EXTREMELY common to see temperatures even colder! Historically speaking, we're just about guaranteed to see another freeze before the cold moves out for good! In fact, every year has seen at least one more freeze beyond today's date areawide! Furthermore, we've got about a month until the historical average date of our last freeze, and freezes have been known to occur here as late as Memorial Day! Those who've already begun their planting this year will still have to prepare to cover those plants at least once more this spring!

This will, though, be the last time we worry about cold temperatures for at least the next week. Winds are to shift bodily out of the South overnight, setting the stage for strong warming into Tuesday. A cold front will be approaching into Tuesday afternoon and evening, which will likely be enough to set off a few scattered showers and t-storms. The Storm Prediction Center outlooks the Stateline for a slight risk of severe thunderstorms, and to an extent, our in-house RPM Model (Timecast) agrees! The key will be the amount of sunshine we see during peak heating times in the afternoon. The more sun we see, the better chances for storms to contain hail and gusty winds. The less sun, the smaller our chances for severe activity! We'll be watching this situation unfold during the afternoon hours, as we expect the best opportunity of storminess to be after 5pm.
