Nashville Severe Weather

Ongoing showers/lightningstorms will continue through the afternoon/evening, clearing out (hopefully, no pinky promises) for nighttime activities – including good ole’ Titans preseason. Things could very well change, we’ll be posting all the updates on Twitter. Below is what the HRRR model thinks will happen. A good amount of these storms will contain lightning, which is sorta (very) dangerous – when thunder roars, go indoors. read more

Remember when we were all SMHing over the 90° days? We were looking at August coming with the dread and Oh Noes? Well…

Just one 90°.

Humidity up to uncomfortable levels is teaming with Other Atmospherey Things You Don’t Care About to create a weekend full of so-so rain/lightning chances. read more

89° is the mid/late August average high.

Great job everybody:

No tornadoes in this forecast but there is rain:

• Today, Gore-geee-usss (for August). After today not so much, but not so bad.
• We may encounter Friday afternoon/evening downpours and lightningstorms scattered around Middle Tennessee. Be lightning safe during HS football games and whatever else it is you’re doing. Most games should be OK but we don’t know which. Here’s the HRRR model (the NAM isn’t quite as stormy):

• Humidity will jump up to Sticky & Uncomfortable beginning Saturday.

• Beginning Saturday through next week, the nerdy sciencey things that make rain will kinda come together to create rain chances without the specificity and timeliness you prefer. I am sorry about that. Midwest low pressure, Canadian upper level low, and about eleventy billion other things, all of it moving at varying rates according to various models, will generally make rain possible here in Tennessee, what a world.
• Rainfall totals look modest, below flash flooding levels.
• No tornado, no hail, no damaging straight line wind events expected. But sure, there may be lightning.
• The most likely time for rain/storms is Sunday night. Confidence level is buns.

Fog should mix out around 9 AM. It’s not gone in the classic sense, it still exists, it just won’t be here for a long time.

Rain in West TN this morning should miss us. Models pass it south of us: read more

A few small, light showers are in Middle Tennessee on radar this morning. None of them local, none of them of any consequence.

The HRRR model is dry for us. NAM thinks a few barely-even-rainers could streak through. Look to the north for any shower coming down. read more

Humidity is a up a bit today but nothing like it was last week.

Models have a few inconsequential showers around Middle Tennessee today but none here locally and nothing that would impact outdoor plans. read more

This day in history: On August 13, 1881 the temperature in Nashville hit 103 degrees for the second day in a row. Eeek and gross. Today’s a good day to step outside, take a deep breath of un-humid air and feel glad it’s not August 13, 1881. read more

A north wind is carrying drier, less humid air into town. Check out these dewpoints today through Sunday morning:

It’s not Fall tho, so delay your PSL excitement, temps are still Summer:

But it’s OK to celebrate this Big Weather Improvement. NWS-Nashville suggested leaving your windows open tonight! read more

70°+ dewpoints are oppressive and we’ve been stuck swamping in them for weeks. Including this morning.

SOON, THEY GONE!

First, we have to dodge a few mid-day downpours:

• HRRR model has more showers (see below).
• NAM3 and other convective models have fewer showers covering less of us.

• Cannot totally rule out a few lightning strikes but think this is mostly a rain event, and only for some of us.

After today, it won’t rain much for a while.

• Humidity will drop. It’ll take a while for north winds to deliver that crisp(er) air from Indiana and Ohio.
• By Saturday you’re going to be doing popular tik-tok things with your friends.
• Watch the swamp get pushed out:

• We go from Oppressive to Comfortable/Sticky for at least about a week or so.
