Heads up, there may be fresher snow! Read the latest Southern California Daily Snow

Continued Chances...

Summary

Mostly sunny Monday and potential snow showers on Tuesday. Mostly sunny through the rest of the week with another chance for snow showers next weekend December 9th - 11th. Overall, a typical December week with no major snow chances.

Short Term Forecast

Sunny Monday ahead of the next potential minor snowfall producing system for Tuesday into Wednesday. Highs will be in the mid to upper 30's with wind gusts 25 - 30 MPH out of the West Southwest. 

Tuesday - Wednesday Shower Chances

The system I had mentioned 2 days ago is still on track to deliver us snow showers chances starting later Monday night and continue through as late as Wednesday afternoon, depending on which model you look at. 

Here's the comparison between the GFS & Euro:

Not a very exciting system at all... That's a little over a tenth of liquid in the spots that get the most precip. That's enough for an inch or 2 of snow depending on how strong a snow band will be. This is not an overly cold system either so snow to water ratios will be around 10:1 or lower. Temps will be in the low 30's and high 20's Tuesday and Wednesday. Winds shouldn't be a big concern either. Don't expect much from this system since it's not a favorable track for us or does it have much moisture. 

Thursday - Friday

I'm expecting mostly sunny conditions for Thursday & Friday. Highs will be in the low to mid 30's and winds should be light up until potentially Friday afternoon. The next system may come into the region around Saturday, but details aren't clear.

In terms of nicest weather of the week, Thursday & Friday should have it. 

Here's the Ensemble mean of the GFS & Euro for precip for Snow summit through Friday:

You can see precip chances start to show up on Friday night after the chances for Tuesday/Wednesday showing up earlier in the week. But overall... very low amounts are forecasted by both models with the GFS the drier one. 

Extended Forecast

The forecast gets a bit murky over the weekend with another chance for precip/snowfall starting Saturday December 10th and continuing into Tuesday December 13th. 

The GFS ensemble mean shows a trough over California on Saturday:

But that doesn't necessarily mean we'll see the storms as both the WPC model and the Ensemble Mean of the GFS don't show much... 

Here's the WPC model through Monday morning counting for all of this week:

And here's the GFS Ensemble Mean:

Northern California is heavily favored along with the whole Pacific Northwest. So... I can't guarantee any of these potential storms on the operational models will pan out for much moisture down in SoCal. We'll see what happens...

Till the next one... Mike out.
