Current Radar
Our dreary day will continue as we enter the afternoon and evening period for Middle TN. Have some showers and thunderstorms scattered across the region currently with more to our North, West and South. Have had a few showers developing in our area this afternoon so we will keep an eye on those as we head into the evening hours.
Current Radar
So far so good on the radar with no showers around our area. Tonight will be much of the same as what could be said for this afternoon. May get a few scattered showers thrown our way this evening; as always, we will let you know if we see any showers developing that could reach us.
A humid, but not too unstable, airmass is atop us this afternoon. This means a few isolated rainers have been racing north. This will continue through the afternoon, then start to die down (but not completely killed off) overnight. Any rain we get will be of little consequence.
#1 That “H” in the Atlantic is known as a Bermuda High. High pressure suppresses rain chances.
#2 That “L” is a surface low. It has caused major flooding in Louisiana. It is pulling moisture in from the Gulf and creating a flash flood threat for those to our west and southwest.
Afternoon showers that develop will quickly collapse and not pose much of a problem for evening plans. Expect mostly dry conditions with temperatures cooling back through the 80s.
A cold front will be on the approach from the northwest, and the tropical low we’ve been discussing all week long will inch closer to our area. These two systems are expected to merge over the weekend, so throughout this process we can anticipate *at least* scattered storm activity. Additionally, if you are traveling west or northwest over the next few days, you can expect to run into rain at some point.
Like clockwork, any rain will end quickly as we lose daytime heating this evening. Temperatures will fall through the low to mid 80s for any outdoor plans, but it will still be quite humid.
The chance for thunderstorms will increase slightly on Thursday in accordance with another slug of moisture that swings our way from the Gulf of Mexico. To better visualize this, check out the PWAT values (note: “PWAT” is short for precipitable water…known as the “measure of the depth of liquid water at the surface that would result after precipitating all of the water vapor in a vertical column over a given location…”).
