I finally got around to editing the shots from the April 7th photogenic, splitting supercells that produced monster hail to my north in Cedar Rapids. The crepuscular rays and gold lining shining around brand new development were something else! More of this tomorrow?🌩️#iawx

Just found a loaded gun in my Snickers bar. I'm literally shaking right now. #wxtwitter

The Predecessor Rain Event (PRE) associated with Hurricane Helene can be visualized with radar & mid-troposphere heights (blue lines).

Helene's interaction with a cutoff low brought a frontal boundary to a stall over western NC with a deep moisture plume well ahead of Helene:

What a warning for those in the southern Appalachains. #Helene

My paper on mergers, nudgers, and collisions (oh my) has been ACCEPTED for publication!!!🎉

Here's a teaser: where are nearby cells (and how many are there) prior to tornadogenesis? We found interesting differences even at 30-minute lead times:

What week of winter weather in Iowa! Thank you snow plow drivers and others! Lapse combines @iowadot track-a-plow locations, DOT/DPS Road conditions, and NWS RADAR since 12 AM last Monday. Re-use as you wish. #iawx

[NWS Des Moines @NWSDesMoines]

It is 𝗥𝗘𝗔𝗟𝗟𝗬 𝗡𝗔𝗦𝗧𝗬 out there on many roadways. @iowadot has 𝗱𝗼𝘄𝗻𝗴𝗿𝗮𝗱𝗲𝗱 most of the Des Moines Metro interstates/highways and I-80 over through Iowa City to 𝗧𝗿𝗮𝘃𝗲𝗹 𝗡𝗼𝘁 𝗔𝗱𝘃𝗶𝘀𝗲𝗱.

Seriously consider avoiding travel if possible.

[NWS Des Moines @NWSDesMoines]

Buckle up for this forecast update.
🧐
A northward shift in storm track has been signaled the last few model cycles, and you can probably guess what that means for the area.
🤔😮⬆️🌨️
More snow, and our first sizable winter storm of the season. #iawx #winteriscoming

Every Storm Prediction Center outlook from 2023 in 30 seconds. What day(s) do you remember the most?

[Evan Bentley @evan_bentley]

Hilarious. This observer is having a heck of a time this evening. 😂

[Alan Shriver @Tails_Shriver]

I love snow as much as the next guy, but I think it’s high time to give more of this to the lower 48. We’re now 8 inches short of our entire seasonal average (77.9”) and it’s *checks notes* December 17th?

[NWS Anchorage @NWSAnchorage]

This is so unnecessary. #akwx

[National Weather Service @NWS]

Today marks three years since the historic derecho tore through parts of the Midwest. Where were you as the storm hit? #iawx
