Forecast Discussion

Obviously, the main focus of the forecast today is the threat of severe weather this evening into tonight, but first, the warm temperatures.

Out ahead of this strong storm system, we’re in what’s called the warm sector. Essentially, it’s an area where southern and southwesterly winds in the wake of a warm front that basically pumps in warm and moist air that gives fuel for strong and severe thunderstorms.

That creates instability in the atmosphere, but that’s not the only part of the equation, you also need wind energy and boy, will we have it.

All of this has led the Storm Prediction Center to place our area in a slight risk (essentially a 2 on a 0-5 scale) for severe weather for the day on Friday with an enhanced risk (3 out of 5) just north of our area where there are slightly better dynamics.

This will not a huge outbreak of severe weather by any stretch of the imagination, however a few severe storms may occur. The main threats will be localized damaging wind gusts, a chance at a bit of large hail and, while it’s unlikely, we can never rule out the possibility of an isolated spin-up tornado.

As for timing, the models are trying to spawn a broken line of storms out to the west around noon CT and slowly moving them into our area as they merge into a more solid line through the night, impacting our area between 6 and midnight.

After the cold front passes through, temperatures plunge back to right around seasonal levels for Saturday and slightly below.

Temperatures will be downright wintry tomorrow night thanks to clear skies allowing the heat to escape, temperatures bottoming out around the 30ºF mark, less than 36 hours after highs approaching 80ºF!
