Our NWS forecasts a storm-making frontal boundary will sink south tonight, setting off a cluster of storms around midnight. The HRRR model (not shown, because there is nothing to show) isn’t much of a believer – it thinks it’ll barely rain overnight. The RAP doesn’t predict heavy showers/storms, either. It’s unlikely these storms will be strong or severe.
Lunchtime Update on Severe Weather Chances Later Tonight
New model runs and a Storm Prediction Center update are in.
Storms are moving NW-to-SE today. The morning showers which moved south of I-40 are long gone, and there’s not much on the radar to our NW to cause any rain-out/washout concerns for outdoor plans later this afternoon and tonight.
Severe Weather Possible Tuesday; More Rain Wednesday?
Today – Thunderstorms Possible Very Late – High 75
The airport picked up almost a half inch of rain today. Rain and cloud cover conspired to keep us cool, but it was not cool enough to break the record for lowest high temperature: 68 set back in 1970.
Stormy Monday Morning; Severe Weather Possible Tuesday
Today – Scattered Thunderstorms – High 88
Today we were set up for widespread afternoon pop up thunderstorms, and that’s what happened.
Afternoon showers should diminish after sunset, only to be followed by another complex of storms to move in from the west. In-storm updates can be found on Twitter @NashSevereWx.
More Rain, Heat, & High Humidity Through Monday
First, another appropriate use of summer:

Tonight
We should be rain-free for most of the day. Rain and a few thunderstorms are forming along the Ohio River. HRRR at 8 p.m. tonight:

Those Ohio River storms will come south through Kentucky later tonight, arriving here around 11 p.m.:
Humid, Wet, & Stormy Weekend (but not a washout)
Saturday morning looks OK rain-wise, but Saturday night and Sunday look wet. Below, we review the entire weekend, model-by-model.

Stormy, Wet Weekend
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.
HOT & Afternoon Thunderstorm Chances Continue
Rest of Today – Isolated Showers Possible – High 95
Can you say HOT? That is all it’s been today. The heat index reached 101 this afternoon. Unfortunately (or fortunately, depending on your point of view), it does not look likely any shower or thunderstorms will be cooling us off this afternoon. Most of the thunderstorm activity is far off to our east.
Hot. Storms Possible Wednesday.
Rest of Tuesday – Isolated Showers Possible – High 92
Widely scattered thunderstorms are popping up, mostly to our south and east. A few may fly by today. Lightning is the main concern, although we can’t rule out an unusually strong cell or two.
Hot, Humid, Isolated & Random Thunderstorms Possible
Rest of Today – Isolated Showers Possible – High 90
There is a very small chance of an isolated shower this afternoon through sundown. Don’t expect anything. THe HRRR model scatters showers just about everywhere except here. This is Monday 4 PM:
