High pressure returns to the area today as a weak upper low moves east across southern California.

Highs today are expected to reach the lower to mid 50s at lake level and the lower 40s at the 8,000 foot resort level under mostly sunny skies and light winds. Lows tonight are forecast to drop into the upper teens to lower 20s under clear skies.

An upper level low pressure trough and associated cold front off the Pacific Northwest coast is forecast to bring increasing clouds and southwest winds to the Tahoe area on Friday.

Highs on Friday are projected to reach the mid 50s under with gusty south to southwest winds 20 to 35 mph in the afternoon. Wind gust along the Sierra crest are expected to increase into the 60 to 80 mph range by afternoon.

The fast moving and dry cold front is forecast to move through the Tahoe area Friday night leaving a cooler air mass as high pressure rebuilds in on Saturday.

Longer range forecast models are coming into better consensus with regards to a major pattern change early next week.
