Air Quality Alert has been re-issued for the Louisville Metro this afternoon/evening and will expire FRIDAY NIGHT at midnight. Code Orange Level. There is a chance we could see this extend into Saturday.
The video today will focus on an update to the weekend setup and how next week will play out. It looks like a series of fronts will get us to a good taste of fall weather. Not just one.
As highlighted in the video, there are some signs from of the HI-RES models that a complex of thunderstorms may develop near Cincy Friday afternoon. The models hint that an outflow may develop out of these thunderstorms and race southwest toward WAVE Country Friday night. Setups like this are nearly impossible to forecast with a remote of confidence a day in advance. But it is worth watching due to the multi-run hints of this setup. I should have a better idea tomorrow when I update the blog, but trying to at least give a small heads up for now.
The trend the past 24 hours is to keep most of the tropical moisture to our southeast this weekend. The question is how strong the ridge of high pressure to our west will limit our thunderstorm coverage. It still appears the more south/east you are---you are less protected. So thunderstorm chances will remain in the forecast---but perhaps lowered a bit for most of WAVE Country.
In turn, this means a hot weekend with more 90s.
This is still on track to arrive later Wednesday into Thursday. This means that we may squeeze out 90 degree days UNTIL it arrives. Quite the stretch for September standards.
The front will not have much of a drive to it to keep going much further to the south of KY. So it may very well "stall" over our area or just to our south until the next front moves in.
This would likely keep the rain chance elevated Wednesday night through Friday (the 11th). Especially for southern KY. Southern IN may benefit from a drier period.
This one looks more moisture latent. So this could lead to a more stormy setup for NEXT weekend (12th/13th).
The air behind that front comes in from the west than north, so do not expect much relief from this front when it comes to cooler weather.
THIRD FRONT (Main One to Watch):
This will arrive on the backside of a strong upper low in Canada near the 16th. This is the one that should finally give us a good northerly flow of autumn weather combined with sunshine!! And it may linger for a few days. We shall see.
In other words, don't expect major changes in our weather for at least 10-12 days.
