The high pressure ridge appears to have broken. While this doesn’t automatically bring in Atmospheric Rivers, at least it is a start! For Thursday expect cloudy conditions with scattered snow flurries, with chances of up to an inch of accumulation, slightly cooler temperatures with highs expected in the mid 30s at 10,000’, and moderate winds from the south. Another chance of slightly greater amounts of precipitation exists for Friday night into Saturday, with 1-5” possible at higher elevations.
Long term: Models are showing greater probability of a low pressure system moving in from off shore during the period of Monday thru Tuesday evening, bringing the possibility of 0.6-0.75” of water into the Sierra, which could mean between 5-10” of snow at higher elevations. Snow levels are expected to start high above 7500’, and drop down to 6000-7000’ by Tuesday night.
