Moving this morning in our general direction are storms that last night caused Severe Thunderstorm and Tornado Warnings in the midwest. This storm complex is now much weaker and crossing the Ohio River, moving south through Kentucky. Most models think these storms will further decay and then completely fall apart before the Tennessee state line. (A few models predict the system – while weaker – will at least hold its precip and cross into Tennessee along and east of I-65).

End of Summer Heatwave
Record highs at BNA on Tuesday (97 in 2018) and Wednesday (97 in 1955) could be tied or even broken.
NWS-Nashville, 9/18/22, AM Forecast Discussion

Hot, but not as humid as the other heatwaves this summer. Dewpoints upper 50°s (Comfortable) / lower 60°s (Sticky) during this End of Summer Heatwave.
There’s little to no hope of rain in the next 7+ days.
Upper 90°s Next Week. No Rain in Sight. Hot & Dry for How Long?
Today will be the same as yesterday and the day before. Then things get…worse.
- The dewpoint will rise a from Comfortable to Sticky starting Sunday, continuing through Wednesday.

- Temps go Full Summer through the end of Summer. Fall begins Thursday at 8:03 PM.

This is hot but it’s not even close to the worst heat we’ve seen this summer because dewpoints — although Not Great, Bob — won’t be that bad.
Haze, Heat, & About Fiona
When Will We Fall Down?
Gonna Get A Bit Toasty, But Still Boring.
Boring is good.
A ridge is an elongated area of high pressure. We’ll have one for a while. That means
- No rain for at least the next 7 days, maybe longer.
- Temps gradually warming each day, #StillSummer
- Reasonable, borderline comfortable humidity. Surface winds aren’t pumping that Gulf of Mexico humidity in here, keeping the swampy away.
We will still sweat.

When will the heat break?
Models disagree (shocking, I know).
Euro (below) thinks late next week (Friday the 23rd), the first full day of Fall!
