Summary: The low pressure system which resulted in scattered light showers over the south valley has now moved eastward into Arizona. In the meantime, a new low will drop out of the Pacific Northwest and into northern Nevada this afternoon. The combination of these two factors will put California in a northwest flow aloft. The surface flow is also onshore. This will continue to feed marine air into the valley for the next 48 hours. Temperatures will accordingly be marginally below average through Wednesday. Upper level high pressure off the Pacific coast will nudge a bit further inland Thursday through Saturday, resulting in a minor warming trend.
The next overall change in the pattern will occur Sunday and Monday of next week. I didn’t get a whole lot of model help in trying to nail down a low pressure system which will affect central California. Currently, if there’s any model consensus at all, it is that this system will be too weak for showers over the valley but with lift over the mountains, showers will be possible early next week over the Sierra Nevada and possibly even the foothills. This remains somewhat of a low confidence forecast, but for now we’ll keep the forecast dry though cooler on the valley floor as we head into early May.
After Monday of next week, high pressure will remain just off the Pacific coast with a new inside slider heading into Nevada next Wednesday. This pattern would not be conducive for precipitation, so we’ll maintain a dry forecast moving forward.
Forecast: Mostly clear skies with occasional cloudiness through Saturday night. partly cloudy Sunday through Monday. Mostly clear Monday night and Tuesday.

Two Week Outlook: May 6 through May 12: This model indicates the pattern will remain fairly active over the west. Even though the chance of rain remains low, it certainly cannot be eliminated. Temperatures will run marginally above average.
May: As we now enter the dry season, precipitation chances, according to this model, will be that of most Mays, in other words, near seasonal. Nothing too dramatic shows up as far as temperatures are concerned with readings near to marginally above average.
May, June, July: As we move through the late spring through mid summer, precipitation opportunities will be typical, in other words, not very high and that’s especially true for June and July. For this 90 day period, temperatures are projected to run somewhat above seasonal values.
Winds: Winds will be generally out of the northwest at 5 to 15 MPH through Friday with the exception of this afternoon when local gusts to 25 MPH are possible, mainly along the I-5 corridor.
Rain: Expect dry weather for the next week to possibly ten days.
