Currently it is -6F up top with 20 mph winds gusting to 30mph. Very light snow should continue on the hill through this evening as the last arctic surge moves through later this afternoon leading to additional accumulations of several inches by the Monday morning report. Valleys should see some periods of sun.
Ironically, the cold front has warmed the valleys by mixing out the very cold air, but inversions will reform beginning tonight leading to very cold temperatures. Mountain slopes, though, will begin warming tomorrow as we see sun and then warm further on Tuesday as the air arctic air mass moves east.
A couple of weak and disorganized Pacific waves move across the area or just south of the area late Tuesday. Snow may begin late Tuesday or Wednesday and continue until late Wednesday night. The leading wave, though weak, will contain some moisture and will turn the winds to the northwest, so I might expect 3-6” from Tuesday night through Thursday morning.
Perhaps a short break on Thursday before the next stronger wave approaches our area. The American model insists the wave will be progressive which leads to a good shot of snow for Friday, but the European model has this wave splitting as it enters the coast, minimizing or eliminating precipitation for our area.
In either case, both models have another wave timed for late in the weekend which should produce some snow for our area.
