Warm and dry spring weather prevail for much of the week in South Lake Tahoe

SOUTH LAKE TAHOE, Calif. - The first day of Spring is today, March 20, and the weather isn't taking any time to fit the season. Temperatures will warm rapidly through the week with record temperatures near 80 degrees possible in the valleys and mid-to-upper 60s at Lake Tahoe. Warm temperatures will last through the week with another storm system possible by the end of the weekend or early the following week.

If the Reno Airport reached 80 degrees, it would be about a month earlier than its historical average of April 25 for the first occurrence in a calendar year, although not the earliest which occurred on March 12, 2007. For South Lake Tahoe, the average first date of the year to hit 65 is April 17, but in 2015, that day was the earliest ever on January 25.
