The word of the day: HUMID. It felt generally gross outside, with dew points running in the low to mid 70s throughout the day…that’s “bad” territory on the Muggy Meter:
Abundant humidity will remain in place through Thursday night, but at least a little bit of relief is in store for the weekend.
We’ve seen some showers and storms popping up in the heat and humidity, but those will fizzle out after sunset — still, an isolated sprinkle or two is still possible overnight into early Thursday morning. The HRRR model’s radar simulation shows that trend:
Temperatures tonight will only drop to the mid 70s:
High temperatures Thursday will reach the upper 80s and low 90s…
…with the heat index close to 100° again:
A better chance of scattered storms will move in Thursday afternoon and evening. I’m not thrilled with any one forecast model’s depiction of those storms, but I think the BAMS model here has a decent handle on things:
A few of the storms could be stronger, especially to the northwest of Nashville — that’s where the Storm Prediction Center has outlined a “Marginal Risk” of severe weather:
That’s level 1 out of 5, so don’t panic — we’ll keep an eye on any storms that develop, just in case they get a little frisky. There could be some storms in the area for the start of Live On The Green…and it will still be warm and sticky:
Don’t let that stop you from joining the fun at Public Square Park — just check in with Lisa Spencer on our evening newscasts tomorrow (or download the 4WARN app and check the radar) before you head out.
That system will usher in a slightly drier air mass for the weekend, but it will still be hot — highs will top out around or above 90° Friday, Saturday and Sunday, with just an isolated storm chance each day:
The heat will stick around early next week, with highs remaining in the low 90s.
Looking ahead to Eclipse Day on Monday, things are still looking…adequate. The American GFS model is showing a decent amount of cloud cover during totality:
The more-reliable European model is a little more optimistic:
Those are the only two major forecast models in range of Monday at this point — we’ll have a lot more data to look at over the weekend. Some spotty showers and storms are still possible as well…not a washout, but still at least a slight chance of rain:
Fingers crossed for good visibility! I’ll have an update on News 4 at 10pm…
- This is the 3 billionth total solar eclipse, but here’s why this one is special.
- What to do if your solar eclipse glasses won’t arrive in time.
- The worst things that could go wrong during the eclipse.
- The strangest and scariest eclipse myths throughout history.
- Related to that story: for many ancient peoples, solar eclipses were a reason to be afraid — very afraid.
- If you’re one of the millions who will see an eclipse for the first time on Monday, prepare to feel changed forever…at least, according to an eclipse-chaser.
- There’s no shortage of stories of animals acting strangely during eclipses.
- The eclipse will let astronomers see the hottest planet (Mercury) like never before.
- July 2017 is statistically tied with July 2016 as the warmest July in 137 years of modern record-keeping.
- There’s a 1-in-3000 chance that the temperature records set between 2014 and 2016 were purely natural. (That’s low.)
- Astronomers have discovered two “super-Earths” located in the habitable zone around Tau Ceti, our nearest Sun-like star.
- Will scientists ever discover life without a home planet?
