Weather continues its roller coaster Spring in South Lake Tahoe

SOUTH LAKE TAHOE, Calif. - Spring keeps teasing us in the Lake Tahoe Basin - we're almost to continual warm days, then a new system skirts above us and changes the forecast. In the week ahead, an upper-level low will be moving north of Lake Tahoe, but temperatures trend roughly five degrees lower on Wednesday as some of the cooler air filters in behind the cold front. The air is unstable, bringing a chance of rain before mid-week and again over the weekend.
