COOLER WEATHER READY TO RUSH IN
High on Tuesday were the hottest of week. Bakersfield got up to 102°. It was the third triple digit day of 2017 (and May). A number of surrounding towns saw 104° on Tuesday, including Delano, Wasco and Arvin. It was particularly hot in the mountains. Tehachapi recorded 90° and Gorman hit 92°. The heat was due, in large measure, to a weak easterly pressure gradient coming in to the south valley. As upper level high pressure repositions to the Gulf of Alaska, the pressure gradient will once again shift to bring about an onshore flow. That will, by itself, cool down the central valley somewhat. Highs on Wednesday will be down 4-6° in the upper 90s.
But then a trough of low pressure will intensify across the western coastal waters with substantial cooling at all levels into Thursday. A ten degree drop is forecast from Wednesday through Thursday. Some very nice weather is expected to settle in for Friday and Saturday. The beginning of the Memorial Day holiday weekend will be delightful with sunny skies and highs in the low to mid 80s. It calculates to an A+ on the Muziometer. Upper level high pressure will make a brief resurgence Sunday and Monday with highs aiming back to the mid and upper 90s. Some cooling is forecast thereafter. However, a lot of disagreement is raging among the European and major American model by the middle of next week.
First, the European is predicting an interesting trough of low pressure extending toward our state from the eastern Pacific by Wednesday. It would keep temperatures down a bit and perhaps bring us some clouds. The American model is advertising a building ridge with sunny and warmer weather to expect. At this time, I am going with the cooler European solution that is a continuation from yesterday. If ridging is shown for next week in another day or two, my forecast may adjust a bit. In neither case would any rain fall in Kern County. I will remind you that the American models have indicated an enhanced chance that one or possibly two weather system producing some precipitation could affect central California during the first half of June.
