Abundant Summertime Sunshine
Very nice weather is underway for all of central California. A low pressure system spun its way into the state yesterday just south of Kern County. It introduced somewhat cooler air on Wednesday, but the system is now retreating to the east. Temperatures are up a few degrees from yesterday as a result. That low will be causing flooding rainfall for extreme southeastern California and much of Arizona through Friday. Meantime, another push of cooler air is headed our way from the north.
On Friday, south valley temperatures will actually be up a bit with what is known as "pre-frontal warming". Then the cooler air will arrive Friday night and Saturday. But it really isn't significantly cooler. This weekend's temperatures will be peaking in the low to mid 90s. Next week will be sunny with gradually building temperatures under an expanding upper level ridge of high pressure. The ridge is retrograding, moving westward, from Texas. Temperatures are predicted to rise back to just over 100° by the middle of the week. But computer models are not quite as bullish on the intensity of this next blast of hot air.
Heat Wave #5 will be minimal with highs in the 100-103° range. That forecast is down several degrees from yesterday's thinking. The big Labor Day holiday weekend should start hot, but indications are that a cooling trend will develop by that Sunday or Monday. No rain is expected during the rest of August.
