Temperatures in the Central Sierra Nevada are expected to cool off after hovering above-average since Monday, but don’t expect precipitation over the region anytime soon.
“If anybody out there is hoping for rain and snow, we don’t have any good news,” said National Weather Service meteorologist Darren Van Cleave.
Since late October, high-pressure parked over the eastern Pacific Ocean has weakened weather systems that would otherwise sweep into California this time of year, Van Cleave said.
The Weather Service has forecast a slight chance of rain for the Central Sierra on Tuesday, but Van Cleave estimated it may not materialize.
“We’re all a little gun shy to say anything for sure because the models have shown that in the extended forecast for the last few weeks and it just hasn’t happened,” he said.
The high pressure also contributed to the unseasonably warm weather in Central California over the past week.
Daily high temperatures have hovered around 73 degrees in Sonora since Monday. That’s 8 degrees warmer than the average for November, according to AccuWeather, a private weather forecasting service.
Van Cleave said some “weak disturbances,” thanks to a weather system from the Pacific Northwest, will bring temperatures in the low-60s beginning today.
However, most of the precipitation from those disturbances will be on the eastern side of the Sierra Crest, except for “maybe a few snowflakes in the High Sierra,” Van Cleave said.
