Skies were clear on Tuesday morning with a chilly start to December. Lows managed to slip back into the 30s in most parts of the south valley. Bakersfield dropped to 34°, which was up 2 degrees from Monday. Delano recorded a low of 29°, up from Monday's 26°. Afternoon highs under hazy sunshine rose to the upper 50s. I believe we will see another cold night in the 30s, but not quite as cold as this morning. My forecast lows range from 33 to 37 degrees by Wednesday morning.
Upper level high pressure will bring a nice day on Wednesday, but there could be some patchy fog. The fog that forms may become locally dense by mid-morning before dissipating by noon. Highs will push into the mid 60s. A chance for rain is foreseen late Thursday and into early Friday morning. Nothing heavy is expected. Probability of precipitation is 20% in the south valley and 30% in the mountains. Only a few hundredths of an inch is forecast with this frontal passage. Windy weather out ahead of the cold front will help lift Thursday's temperatures to the low 70s with pre-frontal warming. But the mercury will drop again to the upper 50s by Friday afternoon after the cold front goes by.
Into this weekend I am a bit concerned we might see more fog develop. Highs will be in the 60s under mostly sunny skies, but the caveat is morning fog. Under building high pressure aloft, valley fog often forms. If fog persists into the afternoons, temperatures will be limited to the 50s. Otherwise, we should see 60s. Mountain and desert towns will enjoy lovely weather from this weekend into the middle of next week.
A significant change in the weather pattern is realized by the end of next week with an increase chance for rain in California. I'll be monitoring the computer models through the next few days for evidence of El Nino enhances weather systems headed for our shores.
