Mostly mild week ahead for Lake Tahoe

SOUTH LAKE TAHOE, Calif. - Unseasonable warmth for Northern Nevada and the Lake Tahoe Basin continues (finally) into mid-week with Sunday being the warmest day. The heat will pop some afternoon cumulus build ups and may fire off isolated showers or even a clap of thunder (10-15% chance) south of US-50. We will continue to see above-average temperatures Tuesday and Wednesday as high pressure builds briefly over our region once again, according to the National Weather Service (NWS) in Reno.

Keeping with the definition of spring, we`ll see another change in the weather as a weak shortwave trough and cold front swing through the region late Wednesday. Highs may drop back into the 50s for the Sierra by Friday. Plan on breezy to gusty winds Thu-Fri with possible impacts to recreation and high-profile vehicle travel. Light rain chances are possible north of I-80 Thurs-Fri with a cold front.

That hiccup is just that, and the Lake Tahoe Basin will be back into the 70s for next weekend.
