Warming trend continues, gusty east winds later today into Thursday

A strong upper level high pressure ridge along the west coast will expand slowly east over the next few days resulting in a significant warm up for the Lake Tahoe area into the weekend.

High today are expected to climb into the upper 60s to lower 70s around the lake with variable high clouds drifting over the area. A lake wind advisory has been issued for the Lake Tahoe area by the National Weather Service for east to northeast winds 15 to 20 mph with local gusts to 35 mph from noon today until 7 pm Thursday.

These winds are developing in response to a strong thermal or pressure difference between the Great Basin surface high pressure system and an intensifying surface thermal low over Central California.

Large waves up to 3 feet could develop from the middle of Lake Tahoe onto the south and west shores. Even stronger northeast winds to 60 mph are forecast along the Sierra crest into Thursday. Winds overnight will keep low temperatures relatively mild with readings in the upper 30s to lower 40s at lake level.

Sunny skies and warmer temperatures are forecast on Thursday with highs in the mid to upper 70s. The gusty east to northeast winds are expected to slowly diminish Thursday night.

Record high temperatures in the lower 80s are still projected for the weekend with a slight chance of a late afternoon over evening thunderstorm possible Sunday and Monday.
