It seems to snow here in Tahoe quite often on Memorial Day weekend. We had a decent storm last year that dropped over a foot on the crest. We have another storm this weekend but not as big as last years. A cold low pressure is working its way down the Pacific NW coast and will drag cold front and a burst of snow through our area tomorrow night. This will be a quick shot at a few inches of snow above 7000 ft. and maybe a dusting at lake level. Similar to Wednesday and since this will be at night it will have a decent chance of sticking.

Today the sun should peak through as the clouds break apart this afternoon and we hit the 50′s for highs. The cold air will begin filtering on Saturday ahead of the cold front and the winds should really pick up. Temps should stay in the 40′s at lake level and the 30′s on the mountains. It may be like Wednesday where the warmest temps are in the morning and then they fall through the day. Sunday the sun will come back out and the temps will rebound back into the 50′s.

The ridge in the Central Pacfic begins to expand North next week pushing the jetstream North of us. A cut-off low will form and drop down the coast on Monday and Tuesday, but models have it spinning off the Pacific NW coast all week. That will allow us to have sun and some springlike temps in the 60′s most of next week. Eventually the cut-off low will eject inland so the question is where and when. At some point towards the end of next week and into the weekend the low should push inland and we could have some cooler temps and a chance of showers.

Looking long-range at the week of June 6th the teleconnections begin to favor ridging along the West Coast. The long-range models do show the ridge building off the coast that week and that would mean some warmer temps. We saw this in the models a few weeks ago for this week but the MJO and some blocking messed that up. This time the MJO is not forecasted to be an issue and we may actually see a stretch of warm dry weather finally.

So winterlike this weekend, springlike next week, and possibly summerlike the second week of June. Stay tuned & have a great Memorial Day weekend….BA
