One More Sunny, Hot Day - Then Stormy Thursday Night

5:55 AM CVG - 65°, Clear Skies

The heat that we've become accustomed to this summer (or so it seems) is back again today for one last stand. We'll hit a high of 88° under sunny skies.

Tonight will feature a chance of showers or storms sometime starting around 3:00 AM, with lows back down to around the 65° mark.

Things could get a bit hairy tomorrow. The computer models don't indicate a lot of instability, perhaps owing to the fact that we'll have rain around off and on much of the day. HOWEVER... the wind fields indicate 850 millibar (or 5000 foot AGL) level winds of around 64 mph, and 0-6 km shear around the same levels. The result would be severe thunderstorms, conditional on how unstable things get in the atmosphere and how warm we get, with winds being the primary threat.

Whether we get severe storms, we still may see wind gusts to 35 mph outside of any storms. This will be enough to inconvenience you if you're out walking so keep that in mind. (We'll update this situation tomorrow morning, especially if anything changes.) It should NOT, as it appears now, be enough to need a Wind Advisory, much less a High Wind Watch/Warning, but we'll keep our eyes on it. (The windstorm of 2008, which is just 2 years ago yesterday [9/14], should have taught meteorologists across the area to prepare for ANYTHING.) Only one model (the North American Mesoscale) has anything stronger right now.

After that, look for a MUCH better weekend. Even as a front develops to our north, high pressure to our south should keep it and its effects up there, and away from the Cincinnati Tri-State area.
