COOLING TREND BEGINS ON WEDNESDAY
It was the hottest day of the year so far in Bakersfield, despite the high cloud cover. The official high on Tuesday was 93 degrees, besting the 92 about 2 weeks ago. However, this will certainly be the pinnacle of this spell of warm weather. A cooling trend is set to begin on Wednesday as the low level wind starts to switch from an easterly to a westerly flow pattern. Then, a deepening low pressure system in the eastern Pacific will slowly march toward California. Clouds will increase again on Wednesday, but no precipitation is expected yet. That will come on Thursday afternoon and evening in the south valley.
Low pressure will lumber into central California and stay for several days bringing much cooler temperatures and a good chance for showers and widely scattered thunderstorms. At this point, I'm not expecting any particularly heavy rainfall anywhere in the county. However, should thunderstorms develop within the low pressure circulation locally heavy showers are possible. My forecast is for a tenth to a quarter inch of rain in the south valley from late Thursday through Saturday afternoon. In the mountains, up to half an inch is possible. Again, the reasoning for locally heavy rainfall is due to slow movement of the entire system. Also, moisture forecasts are indicating an increase for Saturday, so that we could see heavier rainfall on Saturday than any other day during the upcoming wet window.
Highs will be in the 80s on Wednesday, 70s on Thursday and only the upper 60s for Friday. Our weekend will feature cooler than normal conditions in the 70s with lingering chance for afternoon showers or thunderstorms through Sunday, especially in the mountains. By Monday the low pressure system moves well to our east and upper level high pressure moves in. Highs return to the 80s by Monday and rise back into the 90s by the middle of next week under sunny skies.
