We have a better chance of storms in the forecast today, but it’s still going to be hot and muggy before that best chance of storms develops. High temperatures will reach the low 90s, with the heat index running in the mid to upper 90s by this afternoon:
The best chance of storms will shape up from midday through early evening — the HRRR model’s radar simulation shows the scattered nature of the storms:
Because it’s so warm and so muggy, a few storms could be severe, with damaging winds the primary threat. The Storm Prediction Center has included us in a “Marginal Risk” (level 1 of 5) of severe weather — that means that while we expected numerous storms, a few of those could prompt severe thunderstorm warnings:
Damaging winds will be the primary threat, but slow-moving heavy downpours could cause some localized flooding as well:
Lingering storms still possible on Saturday, but it will be hit-or-miss activity. High temperatures will top out in the upper 80s in between the scattered storms:
We’ll be back up to 90° on Sunday with just a slight chance of an isolated storm:
Next week looks mostly calm — just a slight chance of a storm Monday and Tuesday. Temperatures will heat up throughout the week, as the massive “heat bubble” (responsible for Phoenix’s record heat and the wildfire trouble out west) expands eastward:
That heat bubble will weak as it shifts to the east, but we’ll still be up to the mid 90s by the middle of next week:

- One big piece of the climate change puzzle might actually be pretty easy to fix. Sort of.
- The U.S. military views climate change as a “threat multiplier.”

- One little imperfection in nuclear physics is what allows everything around us to exist…I’d actually call that a perfection instead.
- There’s an article like this every few months (or so it seems) and I link to it EVERY TIME. Because it’s a fun little thought exercise: is time travel possible, scientifically?

- Yesterday was National French Fry Day. So here’s a look at the science behind the search for the perfect French fry.
- The best science podcasts to make you smarter…or at least seem smarter. I would add the BBC’s “Infinite Monkey Cage” to that list as well.
