Tonight: Dry Evening, Temperatures Cool Into the 80s
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.
Saturday: HOT Again, Better Rain Chance – High 90°
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.
NAM 7PM Saturday
NWS Nashville describes forecast uncertainty in the long-term, but indicates that scattered storms will be possible for the next several days:
There is considerable discrepancy between the NAM and GFS regarding the aforementioned low center. The NAM brings the system almost due north to near MEM by 18Z Saturday and merging with the cold front as it approaches from the northwest. This would place Middle Tennessee in a rainfall pattern this weekend, especially areas near the Tennessee River. The GFS, on the other hand, carries the low center farther west owing to the strength of the Bermuda High, and merging with the aforementioned cold front to form a quasi- stationary boundary to our northwest. This slow-moving front wouldn`t approach Middle Tennessee until about Wednesday.
