Shortly before 3AM, Evansville recorded it's coldest since the evening of January 21st; we fell all the way to 20° in the River City - it's been more than 10 months since we dealt with temperatures that cold! Fortunately, the mercury soared back into the upper 40s for many of us as sunshine and weak southerly winds kept conditions comfortable this afternoon. While tonight isn't expected to be anywhere as cold (our forecast currently calls for 28° early Thursday), it comes at a price; the (slightly) warmer weather overnight will arrive along with increasing clouds as our next chance of rainfall inches closer toward the region.
A weak core of low pressure currently situated over Texarkana will help force gulf moisture northward up the Mississippi Valley and eventually into the Tri-State by late Thursday morning. The rain will be sporadic and unorganized at best, but you may still want to keep an umbrella with you between Thursday and Friday morning. In addition to the showers, afternoon highs will also take a hit - we'll only reach 46° on Thursday. By the time the rainfall exits Friday morning, many of us will be left with less than 0.10" but a few of our Kentuckian communities may receive up to 0.25" of total perception.
