Pour one out for what may be the final instance of "getting NAM'd" whereby the NAM model gives false hope of a robust coastal low w/strong frontogenesis banding over a major metro area. It is admittedly more fun when multiple ptypes are involved. The NAM is being pushed into retirement this fall :(

Sorry to hear you were hacked but glad you’re here! Twas a good day in the Missouri valley even though we opted out of the jungle fest farther east that resulted in tornadoes

This is probably when the northern ones had the most promise. A brief entirely scud lowering and then the gust front hit

I like cold and snow and mountains. I do not like heat, humidity, and insane politics

Following up after a weekend of observing #Erin. The real track fell on the left side of the ECMWF Ensemble guidance envelope, but near a solid cluster of members. Only one deepmind member showed a scenario remotely similar to what actually happened.

This morning's ECMWF Ensemble forecast scenarios for #Erin (left) vs Google DeepMind (right). Which do you think provides more useful information about tropical cyclone forecast uncertainty?

this tail event - 10-15" of rain in the upper Guadaloupe basin in 12-24hrs - was explicitly forecast by several high res models leading up to the event! I dont think it was literally impossible to forecast

Let’s do it I’m getting married in October at a little cabin on a lake in Maine. There will be a formal reception the next day but for the ceremony I want something rustic but also put together. Full suit feels too formal. Khakis too preppy. Jeans+flannel (my everyday outfit) too casual. Thoughts?

if you wanna tell a story about the importance of having in-situ obs between 925-500mb, this morning provides a pretty good case study IMO

Seems like the proximate cause there was the compressor stalling not taking off overweight but yeah no good to dump fuel. Mostly just stupid to put too much on to start. Like someone is supposed to figure this out!

The storm near Beaver OK around sunset ended up being the only thing remotely worth seeing, but man the heading east option had a lot of cam support and ended up burning a bit of time near coldwater as a result

lots of problems in the world at the moment including the fact that chasecation25, moved out of june in hopes of actually seeing tornadoes, appears set to kick off without a cloud in the sky or a dew point above 30 from Calgary to Corpus Christi

not sure what it says about the new cali wildfire maps and/or WaPo's visualization thereof that the portion of Altadena labeled as "low risk" from wildfires literally burned to the ground from a wildfire 3 months ago

Guess nobody is allowed to look into model biases anymore? Thankfully NWP is never “biased towards” being too warm or too cold in certain environments. Barrier jets or blocks that act as a barrier to the mean flow? Sorry! Those are woke now
