Mild weather with above average daytime temperatures is settled over South Lake Tahoe, but it won't last long as a new systems hits the Lake Tahoe Basin at the end of the week.

High pressure is keeping the quiet weather over the Sierra through midweek.

A mild to moderate atmospheric river will impact Northern California and Western Nevada late Wednesday through Friday according to the National Weather Service in Reno.

This system will have a period of gusty winds on Thursday with ridges seeing gusts near 100 mph and valleys up to 45 mph.

This will be a relatively warmer storm with rain at lake level and snow levels of 7,000’-8,000’ Thursday afternoon. Snow levels will fall to near Lake Tahoe level by Friday morning.

Western Nevada will see all rain except in the upper elevations.

Those with travel plans across the Sierra will likely encounter chain controls and traffic delays. Some increased flows in small creeks and streams can be expected.
