Half of the Alaska upper air sites with no observations Sunday morning. 😡 This data loss impacts every global weather model in the world. #akwx #weather @wxmanms1.bsky.social @climatologist49.bsky.social

Wisconsin has a new 24-hour precipitation record: 14.55"

This was recorded by a rain gauge in Milwaukee during the August flooding event and shatters the previous record of 11.72" that was measured on June 24, 1946.

Trump moves to dismantle major US climate research center in Colorado The Trump administration is breaking up the National Center for Atmospheric Research, taking aim at one of the world's leading climate research labs.

Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Watch for the errant flag throw that hits a player, stay for the Oscar-winning acting job.

THANK YOU FOR YOUR ATTENTION TO THIS MATTER!

Will there be an update on this in the newsletter?

Trump Cuts Are Killing a Tiny Office That Keeps Measurements of the World Accurate A tiny but crucial agency that maintains physical coordinates like latitude and longitude in the US is struggling as the Trump administration forces out federal employees.

SCOOP from me: the mass exodus of employees from NOAA is decimating a tiny office that literally keeps our measurements of latitude and longitude accurate — and, former employees tell me, endangers the science of how the US understands global measurements:

Relative Short-Range Forecast Impact from Aircraft, Profiler, Radiosonde, VAD, GPS-PW, METAR, and Mesonet Observations via the RUC Hourly Assimilation Cycle Abstract An assessment is presented on the relative forecast impact on the performance of a numerical weather prediction model from eight different observation data types: aircraft, profiler, radioson...

From knowledgeable scientists we’ve talked to, RAOBs have the second largest increase in error for upper air metrics when removed, behind aircraft data.

On average, losing RAOBs will decrease mesoscale NWP forecast skill.

Dry cap vs. wet cap

Just because there's CIN does not mean storms will be elevated. In fact, the left profile supports only surface-based storms (given enough dynamic forcing). The right profile supports elevated storms, given buoyant parcels above the boundary layer.

The NWS mission:

“Provide weather, water and climate data, forecasts, warnings, and impact-based decision support services for the protection of life and property and enhancement of the national economy.”

Again: “…for the protection of life and property and enhancement of the national economy.”

The National Weather Service is a lifesaving public resource. We must save it. The National Weather Service (NWS) is the most important federal agency you benefit from on a daily basis.

Here's a small list of the ways you directly benefit from the National Weather Service on a daily basis.

The agency is a public good that issues critical, lifesaving forecasts and alerts. We must save it from indiscriminate and irreparable damage.

The amount of talent and knowledge that is going to be let go for no good reason whatsoever is maddening. We, as a country, are far worse off without their expertise.

NOAA’s vast public weather data powers the local forecasts on your phone and TV – a private company alone couldn’t match it NOAA operates fleets of satellites, sensors on airplanes and ocean-going buoys, as well as radar, providing the data used by weather forecasters nationwide – and freely available to anyone.

"NOAA is taxpayer-funded, so it is a public good – its services provide safety and security for everyone, not just those who can pay for it." CIRES' @cwiedinm.bsky.social and Kari Bowen explain @noaa.gov's role in U.S. weather forecasts. @us.theconversation.com @colorado.edu
