We’re seeing some elevated showers (mostly virga) offshore but the overall trend looks mostly dry to start next week. Cooler, breezy but trending dry for now, w/ showers north and south early next weekend. Storm fans may have to wait till the end of the month for changes. Stay tuned. 1/17/2026

A lot less grey hair 10 years ago 😂 but it was a fun year the first full year for the #candjtwinado crew, StormRanger radar arrived, @google I/O, Olympic Zone and more. #2016 #tvproduction #broadcasting

In theory yes… ex: PG&E uses ML now mining years of climate data, compares to current/forecast parameters for wx impact severity. A good part of the reason why the PSPS for wind has become more pinpointed vs countywide outages.

AI as the umbrella term - machine learning and deep learning as the core, ex PG&E w/ ML for their wx data/ops for potential energy impact pattern recognition

Caveat…machine learning/AI in weather prediction are useful but have bias issues and require correction, they do represent a new era of helpful tools for potential pattern recognition for weather hazards. weather.ou.edu #OSSTahoe 1/13/2026

One more chance for showers tonight then chilly, dry wind into Thursday. This drier air and clear skies with set the stage for potential 20s-low 30s for inland wind-sheltered valleys Friday and Saturday mornings. 1/7/2026 #CAwx

The difference a year makes: from Winter wildfires in Southern California one year ago, rain surpluses reside in their place to start 2026. No areas in California are currently seeing drought conditions unlike Jan 2025 #CAwx 1/6/2026

Note: we’ve seen a few special marine weather warnings for potential waterspouts, and once those areas of radar detected rotation move onshore, tornado warnings can be issued as was the case at 4:05pm along the Santa Cruz / San Mateo County border (ended 4:15 pm) 1/5/2026 #CAwx

At 59' ft (Tue AM forecast) "59 - Moderate Flooding. Trenton-Healdsburg Road begins to flood at lowest spots on right bank (north side). Portions of Wohler Road downstream also likely flooded, including Wohler Road Bridge over Mark West Creek. NWS will issue Flash Flood Warning”
Flood warning for Mark West Creek reaching flood stage into Tuesday morning. minor flooding late PM/evening peak around 10-11am Tuesday at est. 4 ft+ above flood stage @nbcbayarea 1/5/2026
