Wayyy too early to speculate

These volatile patterns are really a headache from a forecast communication standpoint, especially for post-holiday travel. Forecast apps will probably shift back and forth quite a bit in the coming days. One model simulation might show a major mountain snowstorm, while another keeps the region dry.

Either way, big change from this fall.
The weather pattern across North America this month has been fairly consistent, with a anomalous low-pressure system in the Gulf of Alaska and an anomalous high-pressure system over the Rocky Mountains.
The two pressure systems swap places after Thanksgiving.

What will this mean for CA? That's tricky, as it depends greatly on the *exact* position of ridge. This will probably be a drier period--but temperatures could range from quite warm (if directly under ridge) to quite chilly (if under cold NWly flow east of ridge). TBD. #CAwx

Actually the more I think about it. Jumping to that conclusion about fire season for a journalist is v bad

Not to excuse the illiteracy but tbh I would like to see a clearer explanation from public-facing meteorologists explaining the impact of this complex process tens of miles high.

I hadn't wrote a python script for 2+ years until earlier this fall. I decided to use Gemini to write a python script I had misplaced from college. It got me 95% of the way there, was very glad I had taken a few courses in college to clean up the errors and make things run properly.

That's radiation fog! Beautiful. Whereabouts?
Our "Karl" fog in San Francisco and Tule fog in the Central Valley form from different processes. Karl is advection fog, while Tule fog is radiation fog

I'd expect by Saturday morning. Might get some minor improvement to the north early next week with drier air moving in but San Joaquin Valley prob going to be stuck in dense morning fog thru Thanksgiving. Too early for a ton of details but the pattern is primed for fog

Fog in California
A thick bank of fog blankets California’s Central Valley. The fog is bracketed by the Cascades to the North, the Coastal Range to the West and the Sierra Nevada Mountains to the East. These h...
