Thought experiment for those in the climate space: if we removed all the man made structures in SW US cities like PHX, how might that affect these awful temperatures? Especially the overnight lows. 👀

#Phoenix has a preliminary low of 97F (36.1C). That would demolish the daily mark of 92F (33.3C) from 2023 and 2024, break the August monthly record of 95F (35.0C) and tie the all-time record that was set on July 19, 2023 and tied on July 24, 2026. #azwx

I once toured a home for sale that I discovered was in the FEMA 100 year flood plain. Realtor responded “oh you won’t have to buy flood insurance if you pay cash” 🤦‍♀️

"homes labeled as 'extreme' flood risk experience a 3.3% price discount and stay on the market for a week longer" Sure hope those risk labels have verifiable methodology, considering they "remain pervasive across different FEMA floodplain designations" 🙃 www.nber.org/papers/w35516

How does information disclosure reshape the allocation of environmental risk in the housing market? We quantify the price and distributional impact of the nationwide disclosure of property-level flood risk from First Street on U.S. housing platforms. Using a difference-in-RD design that exploits discrete cutoffs in the disclosed risk categories, we find that homes labeled as "extreme'' flood risk experience a 3.3% price discount and stay on the market for a week longer, relative to those labeled as "severe'' risk. These effects are strongest for coastal properties and remain pervasive across different FEMA floodplain designations. Disclosure also generates significant household resorting: buyers of extreme-risk homes have 5.3% lower income, are more likely to use FHA financing, and are older. Through a discrete choice model, we find that the redistribution of risk to lower-income households is primarily driven by price changes rather than heterogeneous preferences for flood risk.

A forbidden donut near Appleton, WI at the moment. Close enough to the radar site to see hydrometeors (rain/hail) and debris forced to the outer edge of a fairly wide tornadic circulation.

Beautiful! My NWS career began in ABQ, and there was nothing better than terrain interactions to teach me the fluidity of the atmosphere 🤓

Brian LaMarre@blamarre.bsky.social · 3w ago

When we talk about the atmosphere being a fluid, this is an excellent data visualization example showing numerical weather prediction output from the AI Global Forecast System across the Northern Hemisphere from last night through next week. See how one atmospheric "wave" influences the next!

"What I am saying, though, is that as an experienced meteorologist… it is hard for me to imagine that it does not have some negative impact on those model forecasts.” - @wxmanms1.bsky.social www.capitalweather.com/is-missing-w...

Is missing weather balloon data making forecasts worse?

Meteorologists are warning that the missing data may be making severe weather forecasts less reliable. The agency in charge of the launches maintains that the lack of balloon data hasn’t degraded fore...

SPC has issued a 10% area for tornado risk (at intensity level 1 no less), which is a first for that part of the forecast area. This is NOT your typical summer severe thunderstorm risk for areas with a lot of people sleeping and playing outdoors.

So much of the (intense) focus on NWS upper air issues has been on impacts on model forecasts - but we collect this data as part of a global effort to ensure high quality data for climate and atmospheric monitoring, and the US is currently not living up to its commitments. tinyurl.com/4ys6daef

Upper air balloons are not just about data for computer models

Part of a larger global weather and climate data gathering effort - and US appears to be dropping the ball on its commitments

I too can’t help reflecting on 1 year ago today and all that was revealed in the days ahead. A indescribable human tragedy. This is an important read. We’ve got to find ways to take our increasing risk from flash flooding more seriously. We need the will for preparedness. Now. 💔

One year ago, the level of catastrophe in Kerr County, TX was just becoming known - and dozens of families were starting down a path of horrific pain. We need to honor those families by realizing we have a flash flood problem and work to try to prevent future tragedies. tinyurl.com/4zk5tzav
