Tracking East
11/13/09 7:09am
I waited until this morning to see what would be happening with this afternoon/ tonight's system. Last night it looked like there would be two possible tracks, one coming down the Northern Sierra Nevada or one with the low dropping into Northern Nevada/ Great Basin. Well, the Easterly track won. The cold GofAK low will drop through OR/ ID into N. Nevada and then speed off to the East via the Great Basin. What this means for Tahoe is a chance of snow showers (a dusting max accumulation) this afternoon/ tonight and the onset of the coldest temps we have seen thus far this fall/winter season. The plus side of this is that the resorts will have temps cold enough to unleash the snow guns through the weekend.
For Truckee/ Tahoe daytime highs will be in the upper 30s, 20s @ 8k and nighttime lows will be it the teens @ the lake and single digits in Truckee. Skies will be partly cloudy and there will be some gusty SW winds to 50mph today along the ridges, switching N-NE-E on Saturday and increasing to 55mph+.
High pressure rebuilds quickly on Sunday which will bring temps back to the upper 40s for Mon/Tues.
Looking to Wed/ Thurs is when we see our next chance for precip. I have said *major* storm in past posts but we might do better calling it a decent storm. Current forecast show two shots of energy, one Wed night and another Thursday afternoon/ night. Snow levels will generally be 6000' or lower, but will fluctuate between shortwaves. More to come as we get closer.
