How did you like your trip back to early October with today’s temperatures? I know I did, except that I had to spend most of it indoors! Highs surpassed 70 degrees across most of the area (except mainly near cooler water) thanks to sunshine and a warm breeze from the south. A storm to the west continues sending the mild air over the region through tomorrow, but increased clouds and a risk of rain probably mean today’s temperatures won’t be beat.
Through Tonight: Expect a mild evening for any outdoor plans, though the breeze may have a bit more cooling effect once the sun sets. Also plan on increasing clouds as the night wears on. I don’t really expect any rain in here before the period around sunrise, and even then the best odds are west. Let’s call it a 20% chance of rain. Temperatures probably don’t fall much if any below the low-to-mid 50s.
Tomorrow (Tuesday): Compared to today, not so grand. But at least temperatures will still be mild. We’re looking at lots of clouds and also a pretty solid risk of showers off and on during the day (30-40% early, 70% afternoon). I’m not expecting a lot of rain during the day, as the first wave doesn’t have much oomph over us. Still, it should be enough to wet the ground (~0.10”-0.25” in spots) here and there at least. Highs should head for the mid-60s.
Ohio Valley storms: Part of the storm system expected to bring us some raindrops over the next few days is today impacting the Ohio Valley with a severe storm threat that includes tornadoes. Somewhat unusual for this time of year overall, a split jet stream often associated with La Nina is aiding storm development. Numerous tornado warnings have already been issued in Illinois and Indiana as a cold front chops into a warm, unstable and turning air mass. So far, there are not any classic discrete supercells, but the Storm Prediction Center has warned of potentially long-tracked strong tornadoes in the region. And the storms are hauling -- about 50-60 mph -- which also increases their risk of non-tornadic damaging winds.
