The cold for the weekend has been well advertised as we will drop into the 20's and 30's for highs through next week and teens at night. That doesn't do much for us this weekend as the wind tonight into Saturday will be howling as if we are getting a big storm but at most we will get a flake or two. It will make for some cold wind chills on Saturday if you are on the mountains so layer up.
The cold is going to be our friend though as some weak systems moves through next week. Limited moisture can stil bring decent snow when you have 20:1 snow:water ratios. The first weak system will dive in on Monday and into Monday night. It will reinforce the cold air and will bring some light precip to the Sierra.
As the storm spins across the basin it will drop a tenth to a quarter of an inch of liquid and all models agree on this today. That is enough for only 1-3 inches of snow but the average temperature of 20 degrees Monday and Monday night means we could see 1-3 inches at the base and 2-5 inches on the mountain. This will be the kind of blower pow that blows away when you carve.
The next system moves in on Wednesday and is another cold storm with high snow ratios. Some of the forecast models have been consistent with a quarter to a half of an inch of liquid all week as I have been stating. Confidence is building with each model run. This would bring 5-10 inches to the base with 10-15 inches at the summit by Thursday morning. This is still 6 days out so the amounts could definitely change so check back for updates.
In the long-range we could see a cold trough could drop in with cold and snow the weekend of the 4th and then again the weekend of the 10th. BA
