Our Hanukkah/Christmas storm originating in the northwest Pacific has dropped south picking up plenty of moisture and has come onshore in southern Cal early this morning. The low pressure trough currently moving through the Great Basin and soon to move into the San Juans on southwestern flow is accompanied by strong jet support (good winds) and a trailing cold front. Today began with partially clear skies but with increasing cloud cover throughout the day.
We have the same situation of the past two storm with warm air temperatures putting into question the snowline location. Seems the valleys and elevations up to 8500′ will see rain/sleet early in the storm this evening then turn to snow later tonight/tomorrow morning when the cold front enters the equation. The snow will be heavy at times (1″/per hour precip rate) as we go to bed thinking of tomorrow’s turkey (tofu, ugh) dinner. Southwest facing terrain will be favored during the storm and should see 8-12″ or more above 11,000′. The storm continues throughout tomorrow then dies later in the evening along with winds as the trough travels east.
