SOUTH LAKE TAHOE ” Increasing clouds and southerly winds today ahead of the next Pacific frontal system forecast to bring rain and high elevation snow to the Basin late tonight into Wednesday morning.

Strong and gusty south winds of 20 to 30 mph with gusts to 45 mph in wind-prone area by this afternoon. These winds will create hazardous boating conditions with large waves especially on the north shore of Lake Tahoe.

Afternoon temperatures are forecast to reach the mid 60s this afternoon under partly cloudy skies. Low temperatures tonight are expected to be fairly mild due to clouds and wind, with minimum readings in the mid 30s to lower 40s.

Look for rain to begin falling late tonight and continue into early Wednesday morning. Rainfall totals are projected to be in the 0.25 to 0.50 inch range with the potential for several inches of wet snow above 7,000 feet by Wednesday morning. Travel should not be a problem, except over the higher mountain passes above 7,500 feet Wednesday morning.

A break in the weather is forecast from late Wednesday into Thursday as high pressure rebuilds over the area.

The next mild Pacific weather system is expected to bring rain and high elevation snow Thursday night into Friday. This system will persist over the Basin for 36 to 48 hours, so precipitation amounts will likely be greater. Stay tuned for more specific rain and snowfall amounts as we get closer to the event.
