Warmer week; possible showers over weekend
High pressure at the surface and aloft will bring ideal ski weather with more sun and light winds today.
Afternoon temperatures are forecast to climb into the mid to upper 40s around the lake and into the lower 40s at the 8,000 foot resort level.
Lows tonight are expected to drop into the single digits to lower teens at lake level and in the upper 20s at the upper elevations above the inversion. Areas of dense fog are forecast to develop in the Truckee area again late tonight into early Wednesday morning.
Temperatures are projected to rise into the lower 50s around the lake on Wednesday along with increasing clouds in the afternoon. These clouds are forecast to result from instability generated from a weak upper level low pressure system passing over Central California. There could even be some isolated showers developing Wednesday afternoon along the central Sierra with this system mainly south of Lake Tahoe into Mono County.
Longer range forecast models are indicating changes in the weather this coming weekend as a trough of low pressure moves into the Pacific Northwest. This system will bring cooler and windier conditions this weekend but there is still uncertainty as to how much if any precipitation will occur at this time.
