We will likely break our nine month, four day Tornado Warning drought for Ohio. When there is a strong line of storms you can easily spin up a quick, weak tornado. Think of it like this... Imagine winds are going 80 miles per hour down your street, the winds moving down the next street over are only going 60 miles per hour. The 80 mile per hour wind will want to curve over to the 60 because there is less mass there. This can cause a quick instantaneous spin-up. This is not the main threat for damage, the 80 mph would would be.
A derecho is a widespread, long-lived, straight-line windstorm that is associated with a fast-moving band of severe thunderstorms.From what it looks like right now, I do not see a screaming line like last year, BUT that does not mean this will not be as bad. I still think it could easily be classified as a derecho, but I see this more as a cellular storm structure at first, instead of a line, then slowly develop into a line... Here is why...
The atmosphere is just primed and ready to go. We have hot temperatures to fuel the storms... especially this afternoon with a high near 90. The liquid energy for storms, dew point, is already at 68 at 10AM. If you watched the movie Twister, they made mention of the "Dewpoint is up to 70 sir" and as movies are NORMALLY not very accurate... that was and when you have a dewpoint of 70... you have lots of moisture. As a matter of fact, if we have storms pop this afternoon, the chances for them to become tornadic is MUCH better than tonight.
So this afternoon... if we see a few storms fire over Ohio, be on alert for hail, strong winds, and even a tornado cannot be ruled out. The real threat for damaging winds will be tonight after midnight. The energy with these storms will be building after sunset.
