It’s a May surprise in drought suffering California this week with several storms bringing light precipitation to Northern and Central California’s Sierra.Tahoe snow forecaster Bryan Allegretto says on his blog today “snow levels will drop below lake level overnight Monday and we could see a coating to an inch on cold surfaces. The snow showers will linger through the day on Tuesday as the low swings through. We could see 1-3 inches in total on the mountains on the East side of the lake and 3-6 inches on the West side by Tuesday evening. Highest amounts above 8000 ft. along the crest.” He says another system will be impacting the northern part of the state Thursday and Friday with some light showers as far down as Tahoe.
NWS Hanford is suggests Monday and Tuesday will wet the Central Sierra perhaps impacting just opened Tioga Pass.Here is what they say this morning.
