Wet pattern to continue with snow?
6/4/09 8:20am
Active pattern to continue as upper low is still stalled and spinning off the CA coast. The rarities continue as this wet pattern is ending its second week with nocturnal thunderstorms last night in the Tahoe Basin. Looks as if this pattern should last through the weekend and into next week, although not as intense after Friday.
Forecast shows the upper low finally moving onshore and weakening tomorrow and Saturday. What this means is another active day today and Friday, with widespread chances of heavy rains, thunder, lightening, and hail. So the moist unstable atmosphere will persist. One difference is that temps will start to cool a bit as the cold pool of the low moves into the region. Temps this morning are around freezing at 8500', so the chance for accumulating snows exist for terrain above 8000' this afternoon, tonight and through Friday night. Not expecting much, but a few inches, especially on Mt. Rose, Freel Peak, and the higher terrain of the Sierra down towards Mammoth. A side note, Mammoth is still spinning lifts, so the possibility exists for a June powder day if you head that way over the next two to three days. Watching the radar of the past few days, there has been snow in the highcountry of Yosemite, Sonora Pass areas and South to Mammoth, all of this generally above 10,000'. Mt Shasta has also been seeing snow above this same elevation.
High temperatures for today/ Friday/ Saturday/ Sunday in Truckee are 62/56/57/62. At 8000' in the Tahoe Basin, high temps will be 45/40/42/47. For Sat/ Sun, the chance for showers and thunderstorms remain as the upper low off the coast now, moves through the region and is replaced by an overall troughiness along the West coast with reinforcing energy being added by a low coming out of the Norhtern Rockies. The forecast for early next week retains the chance for thunderstorms.
