First, some dudes doing summer right:
Rest of Today – Isolated Thunderstorms – High 92
This afternoon’s thunderstorm helped cool us off. We only made it to 92, instead of the forecast 95, but the heat index still hit 100 again today.
The HRRR model (below) predicts one more shower over Nashville around 7 PM. We think that’s unlikely, but remember, it’s just a model. Use it for guidance, not Gospel.
Friday – Isolated Thunderstorms Possible – High 94
7a 75 . 10a 86 . 1p 92 . 4p 94 . 7p 91 . 10p 82
It will be another hot and humid day, with heat indices again expected to reach 100. An isolated thunderstorm can’t be ruled out. The winds will increase from out of the south, charging up the atmosphere for this weekend’s storm system.
Saturday – Thunderstorms – High 92
7a 76 . 10a 85 . 1p 90 . 4p 92 . 7p 89 . 10p 81
An unusual cold front will make its way south, igniting widespread showers and thunderstorms. The front is forecast to stall across the area, serving as the focal point for weekend thunderstorms. At this time, it does not look like storms will reach severe limits. NWS increases our chance of showers/storms in the evening.
Expect slightly cooler temps courtesy of the extra cloud cover. However, dew points will still be high, which could leave us with heat indices in the 100s.
GFS (American) model Saturday 1 AM through Sunday 1 AM:
Sunday looks just as wet as Saturday, perhaps more so. Rainfall totals through the weekend over 1″ (see below). Not a complete mess, but soggy for sure.
