After wrecking a swath of Florida, Hurricane Ian popped out over the Atlantic Ocean, gained strength, and is bearing down on the Carolinas. Though Pittsburgh is quite far inland we will see the remnants of Hurricane Ian’s rain on Saturday.
These maps show total rainfall forecasts for the next three days as Hurricane Ian moves up the eastern U.S.

Now that summer’s heat is over we may be fooled into thinking climate change is no longer affecting us. Unfortunately, above normal temperatures are predicted for most of the U.S. for the next three months. Southeastern Alaska is the only place with any chance of being cooler than normal.
Heat and drought often go hand in hand.
The seasonal drought outlook through the end of 2022 indicates New England will finally see a break in their drought, perhaps hastened by rain from a downgraded hurricane. But there is no help for the American West where the drought persists and gains new ground (see yellow on the map).
It looks like a spaceship but it’s actually a cloud.
Here’s another one at Palm Desert, California.
And another one — quite ominous! — in the mountains in Patagonia. Do I see a mouth on this cloud?
These are all lenticular clouds which form when the wind blows horizontally toward a fixed object that forces the air to rise and fall in a wave. If the fixed object is a mountain and the air is moist it forms a cloud on top of the mountain. The cloud stays right there, thumb-tacked to the sky, as shown in this time lapse from Mount Teide in the Canary Islands.

Lightning and lots of it!Dave Dicello captured a split lightning bolt simultaneously hitting BNY Mellon and the east end of Duquesne University (more than 1/2 mile away) on Sunday morning 21 August. Click here for his latest sky/panorama photos or here for his website.
This lightning strike in #Pittsburgh was one of the closest I’ve ever captured, and certainly one of the clearest and most dramatic. This isn’t a composite; all these bolts happened within a fraction of a second, creating a terrifyingly beautiful scene. A new all time favorite. pic.twitter.com/IlYp9jNbW2
Anticrepuscular rays… are relatively rare and appear opposite the sun at sunrise or sunset. Caused by the backscattering of atmospheric light, the rays we saw on 23 August spanned the sky. I took a photo from my window but it pales in comparison to Dave DiCello’s (@DaveDiCello) from a different vantage point. His tweet and video are shared below my photo.
What a sunset in #Pittsburgh tonight. It was like nothing I’ve ever seen. I’ve captured anti-crepuscular rays before, but never ones that stretched across the entire sky. And then the color as the sun was going down? Absolutely absurd. This has been a CRAZY 48 hours of weather. pic.twitter.com/IeU6WdF5it
Back in the 1970s and 1990s climate change was slow to ramp up so we fooled ourselves by saying (1) Nothing’s changed yet so it’s not going to change, and (2) Climate change will be manageable because it won’t happen fast.
