The lid stayed on the atmosphere today — thunderstorms just refused to develop over most of the Midstate, and temperatures warmed up to the upper 80s and low 90s. There’s still plenty of humidity in place though, and we could still see some scattered storms moving in this evening. At the time I’m publishing this post (around 6pm), we’re watching numerous storms along the Mississippi River to our west, and along the Ohio River to our north and northwest…and just a few over the northwestern corner of the Midstate:
Those storms haven’t been in much of a hurry — they’ve just been slowly drifting, rather than actually moving. But as we go through the evening, those storms could start making some progress in our direction…or, we could see a few developing in northwestern Middle Tennessee and the western half of southern Kentucky. The RPM model certainly anticipates that scenario:
And the HRRR model gets even more carried away with our rain chances:
Honestly, I’ll believe it when I see it. This morning’s weather balloon data showed a pretty deep layer of warm air above our heads — that’s why the storms didn’t pop this afternoon, and I think it will suppress our storm chances this evening as well. But there’s enough uncertainty to continue with a decent chance of at least a passing shower/storm in western Middle Tennessee this evening, with decreasing rain chances as you go east:
More scattered storms are possible on Saturday, with the best chance along and south of I-40. In terms of timing, the midday and afternoon hours will bring the best rain chances:
Even so, don’t cancel any outdoor plans for Saturday — just be ready to adjust if Mother Nature throws some storms your way. Be ready to deal with hot and muggy conditions in between the scattered storms:
Sunday’s rain chances will be much lower, thanks to sinking motion in the atmosphere overhead (air has to go UP to produce storms). This time of year, the equation is pretty simple: lower rain chances = higher temperatures. Sunday and Monday will quite hot, and still steamy…heat indices are likely to climb over 100 degrees both days:
We’ll get a one-day reprieve from the worst of the heat on Tuesday — that’s our best rain chance in the extended forecast. Back to the mid 90s Wednesday and Thursday, and we could threaten triple digits (for air temperatures) by Friday and Saturday!
Since I’m on the evening shift to finish off the work week, I’ve had a little more time to mine the interwebs for you last batch of nerdery this week…
- Some pretty spectacular video yesterday as severe thunderstorms rolled into New York City and the surrounding area.
- Meanwhile, it’s winter in Australia…and parts of the country are seeing the coldest temperatures in years.
- There’s an app that sends weather and soil data for any spot on Earth to farmers’ phones.
- More evidence that warmer global temperatures will lead to an increase in the frequency of powerful tropical cyclones.
- It’s not just warmer air temperatures driving ice loss in Antarctica…warmer water temperatures might be an even bigger factor.
- Some good news from the climate front: efficiency and clean energy have helped put a dent in carbon dioxide emissions.
- A volcano thought to be extinct is rumbling to life near Rome.
- Some of the most devastating volcanic eruptions in history have one feature in common.
- No, NASA didn’t cut the video feed from the International Space Station as a UFO was entering Earth’s atmosphere.
- It’s been one year since the New Horizons probe flew by Pluto — here’s what scientists have learned from the data they’ve received in that year.
- Pluto (very famously) isn’t technically a planet, but a “dwarf planet.” So, what does that mean?
- The “multiverse” hypothesis is a little mind-bending…here’s a summary for non-scientists.
- Leaving philosophy out of it, from just biological perspective: why do we die?
- Is artificial lighting making us sick? (Not good news for those of us who work under the bright lights in a TV studio at 4am every day.)
- Will LiFi someday replace WiFi? And what is it, anyway?
