A few showers on the radar this morning, but nothing you need to worry about — the showers are very light and widely scattered. That activity will dissipate by midday, leaving us with warm and muggy conditions during the afternoon. Temperatures will top out in the low to mid 80s:
The humidity will be noticeable (maybe even reaching “unpleasant”) with dew points in the 60s later today:
Thunderstorms are more likely to develop this evening and overnight, especially along and north of I-40. This radar simulation (from the NSSL WRF model, if you’re a serious weather nerd) shows the pattern from 4pm through midnight:That’s one version of one model — again, the overall pattern is the important take-away. The specific timing and placement is tough to pin down because this is a “weakly forced” system…while there will be plenty of instability, there won’t be much of a trigger to get the storms going in the first place, and the wind energy won’t be impressive. Still, a few storms could be strong to severe — the Storm Prediction Center has outlined a “Slight Risk” (level 2 of 5) of severe storms for southern Kentucky and northwestern Middle Tennessee, with a “Marginal Risk” (level 1 of 5) surrounding that:
Plan on staying weather-aware this evening, just to be on the safe side, but this is far from an off-the-charts severe weather threat:
- Tropical Storm Adrian has formed in the Pacific Ocean, making it the earliest first tropical storm on record in the Eastern Pacific.
- The West Mims fire in Georgia and Florida is now over 143,800 acres, and half of Georgia’s Charlton county has been evacuated.
- A new study claims that tornado-related fatalities and damage may triple by the end of the century. (The study has already gone through the peer-review process, which means the methodology is sound.)
- Over the past 50 years, 39 of Glacier National Park’s namesake glaciers have shrunk by up to 85%.
- A photo gallery worth your time: some of the most-stunning photos of Saturn taken by the Cassini spacecraft.
- Cassini also spotted some breezy summer methane clouds on Titan.
- Astronomers just got an up-close look at the largest lava lake in the solar system.
