Sunday Afternoon the 4th:


Cold wave moving in Monday night into Tuesday with light snow possible into Tuesday…..Very Significant AR event developing for the Central and Northern Sierra beginning Thursday AM as Kona Low draws up copious amounts of moisture from the ITZ then through Hawaii…as Warm front pushes into the sierra Thursday…..The Dweebs will have a complete and detailed report in the “weather letter” early Monday AM.




No sooner than the Dweebs put out a Platinum Powder Watch this AM, the upper jet with the next Monday-Tuesday system, the models showed the upper jet more along the west coast/CA with little over water trajectory. Although there is still the chance it may flip back somewhat for better snowfall opportunities, the odds are increasing against it.  This is why the Dweebs put out a Watch instead of a warning last night in my weather letter which would be more likely. The watch is now cancelled….

Not only is the pattern quite progressive, but the KONA low developing NW of Hawaii is aiding to pump up quite a bit of warm air over the subtropical eastern pacific. This subtropical ridge will act as a buffer combined with the progressiveness of the pattern to keep this short wave moving rather quickly southeast, instead of digging south first. No doubt this will be another cold system. However, not as cold as it appeared Tuesday but likely colder than the one currently in our area at the moment. Snow showers are still a good bet with light accumulation’s.

Should this system decide to slow down a bit and the upper jet backing a bit more off shore Monday, that would help with snowfall prospects. Although there is still 4 days for a little adjustment, the closer to the event, the better the models are at getting a handle on it.

The longer range still holds the possibility for a light to moderate AR event about Friday the 9th, give or take a day.

More on that later>>>>>>>>>>>
