Official NWS-Nashville ETA is 3-5 PM.
I like the early side of that ETA for a few reasons.
First, the line already passed Jackson TN at noon and I don’t think it’ll take 5 hours to get here.
Second, the latest run of the HRRR model puts the line into Nashville and Williamson County between 3 PM and 4 PM. Below see the HRRR model predicting the radar at 3 PM. This model has been pretty consistent with this ETA all day.
Check back frequently this afternoon for adjustments to the ETA. Storms may arrive sooner than 3 PM.
Updates throughout the day can be found on Twitter @NashSevereWx. If there’s a warning, Andrew will be live on Periscope; we will tweet that link.
