Today's high temperature of 87° was our warmest in a week and a half - we last climbed that high on the afternoon of September 18th when we tipped the scales at 88°. The remainder of the evening will remain quite mild under clear skies; expect temperatures to first fall to 83° by dinnertime before dropping to 73° by 10PM. The clear skies and weak southerly wind flow will help keep temperatures relatively stable during the overnight and predawn hours - we'll wake up to a morning low of just 62° early Wednesday morning.
While our normal low temperatures this time of the year average around 53°, our temperature Wednesday morning will remain about 9° warmer than that. The mild start to the day means we're all in for yet another toasty day ahead - after first soaring to 85° around our lunch hour, we'll top out at 89° in Evansville tomorrow afternoon. If the forecast holds, that high will mark our warmest in nearly two weeks - we last climbed that high on September 13th! Fortunately, much like our Tuesday, Wednesday's hot temperatures won't be accompanied by any of that oppressive humidity. Dew point values should remain the low 60s at their worst, meaning at times tomorrow, it could feel as hot as 90° in some spots.
Our clear skies above the Tri-State are all thanks to a complex of higher pressure that has been hanging around the eastern half of the continent in recent days. That area of higher pressure will be consolidating over the next few days and push to our southeast by this weekend. That migration will only strengthen our southerly wind flow here at home and help force more gulf moisture northward up the Mississippi Valley by the time Thursday and Friday roll around. As a result, there's a slim possibility for isolated rainfall on Thursday and Friday - the greatest chance for rain will likely affect the communities west of Evansville. However, the added cloud cover and moisture in the atmosphere will also help keep temperatures cooler both days; afternoon highs will reach 87° and 84° on Thursday and Friday respectively.
