Terminator: Weather Feed
In which we say farewell to a storm, greet some new ones, and then take a break.
Apologies ahead of time if these are feeling a bit spammy. I forgot to send one out the other day so you’re getting back-to-back posts.
Also, if you have any feedback or requests, please let me know in the comments! Thank you so much for reading 💙
The terminator
No, not the one you’re thinking of.
Our planet this morning. The line that separates day and night is called the terminator. At equinox, which comes Monday, there is no tilt of the Earth with respect to the sun. Meaning the terminator line today is nearly parallel to the axis of the Earth and to lines of longitude.

You get more rain! And you get more rain!
It’s true, although we’ll see if these storms are on the weaker side.
Brief thoughts on likely return to active weather pattern in CA after a much-needed several day break right now. There is *high* confidence that wet and cool conditions will return next week, but right now there is *low* confidence in strength of storms. #CAwx #CAwater (1/4)

But hey, they’re working on getting better at forecasting them.
New research led by Xingying Huang on simulating extreme U.S. Pacific Coast #AtmosphericRiver storms. We found that our high resolution weather model configuration yielded substantial improvements in extreme precip representation. (1/3) agupubs.onlinelibrary.wiley.com/doi/full/10.10… #CAwx #CAwater

No mor’easter
We covered the last nor’easter in the previous newsletter, so we’re just saying goodbye to it now.

The image might be hard to see but some of the top snow totals from that storm were 30-35 inches!
Here is a map of snowfall reports from the storm on March 14-15th. We appreciate all of those who submitted their reports! #nhwx #mewx

Morning coffee weather report
If you’re in California, I’ve been digging this guy’s morning forecasts.

Gravity what now?
These things are gravity waves.
Tuesday / Windsday: Professor Mike Voss @SJSUmeteorology lecture today “strong pressure gradient and subsequent strong low level flow is creating topographically forced gravity waves” #CAwx 3/14/2023

You can check this page and video out for more details, but here’s an excerpt from that page:
The gravity waves seen in this video are known as terrain-induced waves. They form when air is forced upward by hills or mountains into a layer of stable air in the atmosphere. Gravity causes the air to fall back down, and it begins to oscillate, creating a ripple effect. Wind flowing over the Rocky Mountains, for example, can create gravity waves that are felt as turbulence on an airplane.
Supercell me
We don’t get to see supercells in CA often, so let’s take a few minutes to appreciate these towering beauties.
DFW… whoa… 🤯

Of course, these things can produce some pretty damaging weather.

And here’s a larger look at the storm system that swept through Texas and some other states.

Just a quick review
Here’s an update on the CA drought.
Two atmospheric rivers (AR) impacted California and portions of neighboring states, w/ the second arriving as the #DroughtMonitor period ended.
— NOAA NCEI (@NOAANCEI) 4:44 PM ∙ Mar 16, 2023
👀 See how drought has improved in California during the past 12 weeks from ARs continuing to strike the state. drought.gov
And here’s what those different colors in the image on the right actually mean:
What do abnormal dryness and moderate, severe, extreme, and exceptional drought mean? 🤔

Two posts in two days, time for us all to have a break
I know it’s not weather related, but I loved this tweet from the Oklahoma Department of Wildlife Conservation. See you next time.
