More wet weather to return after nice weekend
Look for cloudy skies and showers around the Lake Tahoe Basin today as an upper-level low-pressure system tracks across central California. The best chance for measurable precipitation will be this afternoon and evening, as cooling aloft and daytime heating triggers instability showers.
Forecast models are showing around 0.10 to 0.20 inch of rain in the Tahoe basin by tonight. The snow levels are expected to fluctuate between 6,500 to 7,000 feet, with two to four inches of snow possible in the upper elevations. Motorist planning travel over the Sierra passes later today and tonight should check the latest road conditions before departing. Clouds and showers will keep daytime highs in the upper 40s to lower 50s this afternoon. Lows Saturday morning are projected to drop in the mid and upper 20s with areas of freezing fog possible.
High pressure rebuilds back into the area Saturday and Sunday for mostly sunny skies and warmer daytime temperatures. Highs Saturday are forecast to reach in the mid to upper 50s under a light northerly flow. Sunday will be a very nice autumn day with sunny skies … light winds and highs in the mid 60s around the Basin. Overnight lows will stay on the chilly side in the mid to upper 20s but close to the seasonal normal for mid October.
Winter weather returns with a vengeance next week as a strong Pacific jet stream takes aim at the Northern California coast. The first in a series of Pacific storms will bring increasing clouds and wind on Monday with showers by afternoon. A stronger storm is forecast to push into the Tahoe area Tuesday and Wednesday with periods of rain and snow accompanied by strong and gusty southwest winds. Snow accumulations could be significant with these storms and likely to impact travel during the middle of next week. Stay tuned for more details on snow levels and amounts as this pattern develops. Computer models are now showing improving weather by the end of next week as the jet stream retreats back north into the Pacific Northwest.
