A holiday get together

Our last forecast of 2020 came a couple of days after Christmas in interior California. Bakersfield was a rainy place on December 27th, and that continued to the 28th. Fortunately, the skies cleared on the 29th, so people could spend their last few hours of their 2020 quarantine on the patio, if they felt comfortable with temperatures only reaching the mid 50s. In the spirit of giving, Bakersfield allowed 3 sites, Accuweather, Weatherbug and Forecast.io to claim a tie atop the leader board to conclude this very long year.
Actuals: December 28th, .21″ of rain, High 56, Low 45

Bakersfield, California

I hope everyone had a happy Holiday. If you were among the millions who were in the midst of winter weather during the Christmas Season, then I hope this forecast for southern California can fill you with warmer thoughts.

At 1054AM, PT, Bakersfield was reporting light rain and a temperature of 54 degrees. A narrow band of showers lay across the southern Valley, with more industrious precipitation in the higher terrain of the Sierras and Tehachapi Mountains. This was a more forceful preview of a storm coming later today and early in the workweek.
A deep trough digging into the Pacific Coast is a tailing lobe over a broader jet trough covering the better part of the northern half of the country. The precipitation follows the course of the exiting part of the jet streak from the lobe, but a well defined area of surface low pressure looms off the California coast. Rain and mountain snow will really intensify overnight tonight, with the feature fully onshore shortly after midnight. Rain is likely in Bakersfield, but significant snow in the mountains ringing Bakersfield are all under Winter Storm advisories. The good news is that the storm will move quickly, and be chased out by dry California air by the end of the day. Tuesday looks to be atypically cool, but dry.

Model guidance definitely doesn’t fully clear the Bakersfield by the early afternoon tomorrow, as some outlets suggest, but Bakersfield is not an easy place to get steady precipitation, which is why nobody carries it as late as we do. Still, it arrived early, so why not stay a while? Here is the radar, with that rain hanging around, especially in the mountains.
