All eyes on the gulf and eastern pacific this week as we await formation of new tropical systems. Here's a look at the model trends over the past few days.

Typhoon Dujuan is very pretty. At least the Pacific is making up for a lackluster Atlantic

These ads are unhinged. The bets are so specific as to guarantee an uninformed person will lose money on the weather.

Through extraordinary efforts, @windbornewx.bsky.social successfully navigated a controllable balloon above powerful Typhoon Dolphin, descended into its eye, then collected multiple vertical profiles as we circled inside its eye. A first of its kind type of hurricane data collection.

I know there have been some Project 2029 memes, but what do we need to make it real? Fundraising infrastructure outside Act Blue / DNC? Effective GOTV infrastructure? The vision for a better tomorrow for all of us is easy. No need for vengeance against anyone, just a plan to make a better country

Nice paper by Brice Coffer et al last week that moves us closer to reliable tornado prediction. They resolve issues in model datasets that previously prevented discrimination. Also they look at how observed storm motion compares to Bunkers in tornado vs non-tornado. arxiv.org/abs/2503.15466

Plots of Storm Relative Helicity for non-tornadic, weakly tornadic, and significantly tornadic. There is a clear separation of storm relative helicity values for non-tornado vs tornado cases. Storm motion comparisons for Bunkers right vs observed storm motion for non-tornadic & tornadic cases. Observed storm motion is to the left of Bunkers for non-tornado cases and to the right for tornado cases

Nice to see The NY Times feature our work on the next housing affordability crisis: climate change.

The Hidden Climate Tax: How Climate Change Increases Energy Demand and Costs For Society

Talk from 2025 American Meteorological Society meeting in New Orleans, LA. Jan. 2025 Abstract: This study demonstrates how climate change is already driving large increases in electricity demand and total electricity costs. This occurs due to two things: hotter temperatures drive higher demand (m

More NWS tornado warning trivia. In Oct 2003, the directive for duration changed from "should be 30 to 60 minutes" to 15 to 45 minutes. Plot shows pdf 4 years before and after official change. Early (late) 70.6% (70.6%) from 30 to 60, 66.9% (62.8%) from 15 to 45.

PDF of tornado warning duration from October 1999-Sept 2003, when directive said warnings should be from 30-60 minutes in duration, and Oct 2003-Sept 2007, when directive changed to 15-45 minutes in duration. Distributions show almost no change. Early (late) 70.6% (70.6%) from 30 to 60, 66.9% (62.8%) from 15 to 45.

Never really appreciated the last time I had honey roasted peanuts and a plastic cup on Southwest.

Exploring how RTMA represents derecho events and looking at SPC performance here. Both seem pretty reasonable
