Dry weather today, with more precipitation coming next week
The fast-moving cold front that moved through the Tahoe area Wednesday morning left up to two inches of snow around the Basin, with four to six inches in the upper elevations. Some precipitation amounts from this system included 0.36 inch at Tahoe City, 0.29 at the South Lake Airport and 0.14 at Markleeville.
High pressure building into the region will bring warmer temperatures and generally light winds to the Basin today under partly cloudy skies. Afternoon high temperatures are forecast to reach into the upper 50s to lower 60s, or right near the seasonal normal high of 60 for this date. Lows tonight are expected to dip into the upper 20s to lower 30s tempered by increasing clouds.
The next Pacific low-pressure system is forecast to be much weaker as it tracks onto the central California coast near Monterey Bay Friday afternoon. There won’t see much in the way of rain or snow or even wind with this compact system as it tracks eastward and weakens further across Nevada Friday night into Saturday.
The best chance of rain or snow pellet showers in the Tahoe area is Friday afternoon and evening, as the cooler temperatures aloft with upper low creates some instability triggered by the afternoon heating. Daytime temperatures will be cooler on Friday, with highs in the lower to mid 50s in the Basin under partly cloudy skies.
Just like the past few weekends, look for clearing skies and a warming trend into Sunday. Saturday will see highs in the upper 50s under a northerly flow while Sunday should be the best day for outdoor activities with sunny skies and highs warming into the mid 60s.
Computer models are still forecasting a prolonged period of wet and windy weather, beginning late Monday and continuing through Thursday or Friday of next week, with the jet stream or storm track pushing south into northern California. Any breaks in the weather next week are expected to be short-lived, so pay attention to the details if you’re planning to travel or have weather-sensitive activities.
Longer-range models are still forecasting high pressure to rebuild into the area by next weekend for a return to dry weather and more seasonal temperatures.
