Much more pleasant weather is settling in over central California. This is due to an increased onshore flow into Kern County now that upper level high pressure has receded to the east. A low pressure circulation is spinning just west of San Francisco and this feature is expected to push eastward into our state with further cooling forecast through Thursday. There will be enough instability in the atmosphere to encourage some thunderstorm activity in association with the low as it passes through. I have included a 20% chance for showers late Wednesday and Thursday in the mountains, as well as a minor 10% probability for the south valley on Thursday. No heavy rain is expected, however there may be dangerous lightning strikes in the mountains, mainly to the north of Kern County.
Highs on Wednesday will be in the lower 90s with even cooler daytime readings for both Thursday and Friday. Highs for the end of the work week will only rise into the mid to upper 80s. That represents temperatures nearly 10 degrees below the July norms. Through this upcoming weekend it will be dry and sunny with comfortable temperatures for mid-summer. By next week temperatures should start to slowly rise again with mostly sunny skies.
I'm watching the potential for monsoonal moisture to once again start moving northward by about the end of the 10-day forecast period. Right now no rain is in the forecast, but temperatures should crack into the triple digits again by Thursday of next week.
