Summary: The low pressure system which moved through California over the weekend has now moved eastward into Utah and Arizona. Upper level high pressure over the eastern Pacific is beginning to nose in from the west. Between the exiting low and the incoming upper high, the flow aloft has become out of the northeast, which is an off shore flow. This will enhance our warming trend over the next 72 hours. Some mountain stations are as much as 11 degrees warmer than 24 hours ago. On the valley floor, readings are only 3 to 6 degrees warmer with the exception of Bakersfield which is 9 degrees warmer than yesterday at this time.
The high center will be off the California coast generally for much of the week, but it will expand inland over California and the Desert Southwest. A real inkling of summer will occur by midweek as temperatures are driven into the mid 90s.
The high will slowly weaken by Friday, allowing temperatures to slowly come down while remaining well above average.
Models show a significant low developing over the Pacific Northwest Sunday and Monday with the bottom side of the low sagging into northern California. That region would see an increasing chance of showers. How far south any active weather progresses with this system remains to be seen and depends on model of choice. Currently, most models indicate showers over the Sierra Nevada, but maintain dry weather over the valley floor. At the very least, beginning Sunday a marked cooling trend will begin with occasional breezy conditions and increasing amounts of cloud cover from time to time.
From May 1 through the 5, most models are indicating a significant low will be along the west coast. Even so, climate date indicates the chance of precipitation will remain low.
Forecast: Clear and warmer through Thursday. Mostly clear Thursday night through Saturday. Variable cloudiness Saturday night through Monday and cooler.

Two Week Outlook: April 29 through May 5: This model indicates a trough of low pressure will be off the west coast during this period. The fact that we’re very late in the rainfall season continues to indicate there’s a low risk of showers. Temperatures will fall back to near seasonal.
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 at or less than 15 MPH through Thursday and mainly out of the northwest afternoons and evenings.
Rain: Expect dry conditions through the weekend. We are still looking at late Sunday through early next week. So far, the forecast looks dry, however that is subject to change as an overall pattern change occurs.
