Nate’s now a tropical storm, speeding northeast into Middle and Eastern Tennessee. The center of Nate should pass east of us.

Heat and humidity will continue through Wednesday, but rain isn’t expected over the next 7 days.

A dry north wind is on the way thanks to Hurricane Maria.

Hurricane Maria will pass northward off the Mid-Atlantic coast by mid-week, then into the North Atlantic Ocean at the end of the week. We’re on the western side of it, and as a result we will receive a dry northerly surface wind. read more

Heat and humidity remain. Mid/Upper 60° dewpoints with a high temp of 91° in the shade. It’s going to be much hotter in the sun.

Gross.

Our chance of a brief shower today is small. Someone in Tennessee will get a little wet, it probably won’t be us, but it might. A classic summertime battle of competing forces is to blame for forecast uncertainty: read more

Rain & Storm Chances

Today — Temps soaring to 88° this afternoon should lift our sweaty, drippy air mass, producing a few pop up showers or weak storms somewhere in Middle Tennessee. The rain will probably be northwest of us, but we can’t rule out a shower. Without low instability, this will probably be a non-event, which will end as temps fall tonight. read more

Summary

• 1.5″ to 2″ Monday afternoon through Thursday afternoon is most likely; most of it falling Monday night into Tuesday morning. Flash flooding cannot be ruled out, but it is not expected.
• A Wind Advisory goes into effect Monday at 7 PM until Tuesday at 7 AM for winds 15 to 25 mph with gusts to 45 mph. Expect a few trees down, isolated power outages possible, and hazardous driving conditions.
• Severe thunderstorms and tornadoes are not currently a concern.
• This does not look like a repeat of Harvey, but stay connected to reliable weather information as this storm approaches.

It May Rain and Storm Overnight

We aren’t sure when it’ll start.

Chances begin around 3 AM, or . . . around 10 AM . . . or sometime in between.  Models disagree!

(1)  The NAM3 model thinks 3 AM. Here it is coming down I-24 tonight: read more

Sunny, high 88°, with mid-60°s dewpoint will make a great Labor Day.
