After reaching 65° in Evansville earlier today, temperatures are about to take a hit overnight and early Wednesday morning. Higher pressure building in over the Great Lakes tonight will erode a good amount of the cloud cover that lingered for much of our Tuesday. Gradually clearing conditions overnight paired with a breezy northeasterly wind flow will help drive the mercury back into the mid to low 40s for many of us, but the areas along and north of I-64 could see temperatures dip as low as the mid to upper 30s early Wednesday. As a result, the National Weather Service has issued a Frost Advisory for our northernmost reaches beginning overnight. The Advisory will go into effect at 2 AM and last though 9 AM. Despite the chilly start to the day, it does look as though our midweek will be quite the pleasant one.
You'll be reaching for the jacket before stepping out the door to a morning low of 43° in Evansville early tomorrow and you may want to keep it handy throughout the day - while the mostly sunny skies will help drive temperatures a degree to two higher tomorrow, those northeasterly winds will ensure that afternoon highs remain around 10° shy of the norm for this time of the year. We'll reach 66° in the River City come Wednesday afternoon. Dinner plans Wednesday? Temperatures around dinnertime will remain in the mid to low 60s - we'll fall right back into the low 40s during the predawn hours Thursday.
Thursday will continue our incremental warming trend: after reaching 63° Monday, 65° Tuesday and 66° on Wednesday, Thursday will be 67° and mostly sunny. However, the real warmup doesn't get underway until higher pressure begins to kick to our east late Thursday evening. As the core of high pressure slips to our east, our winds will shift southward - temperatures will surge back into the low 70s on Friday for the first time in over a week and a half; we'll hit 72° under partly cloudy skies as we wrap up the work week. Saturday looks slightly warmer, though added cloud cover will make for a greyer day overall and rain chances will likely follow shortly thereafter - we're expected to see showers and storms return as early as Sunday. Be sure to make the most of the pleasant weather while it lasts.
