Upper level high pressure over the eastern Pacific continues to move further off shore. This allowed a low pressure system to quickly move through the western US yesterday, dropping temperatures between 10 and 15 degrees over the previous day due to a strong push of marine air down the valley. A strong northwest flow aloft is evident above the valley floor and will spread variable amounts of high clouds overhead today. To our north, a new low is developing near Vancouver Island and will be centered over central Oregon by midday Monday. It will then slide into northern and central California late Monday afternoon and Monday night. This system is not carrying much water, however showers will spread down the Sierra Nevada Monday with a reasonably good chance of light showers over the valley floor Monday afternoon into Tuesday morning. This is actually the first of two storms. The second will arrive Friday into Saturday with a chance of showers over the Sierra Nevada and a small chance over the valley floor. Between these two systems will be a layer of cold air Tuesday morning through Thursday morning with readings falling into the 30s and with a chance of local frost which is discussed in the frost summary below. High pressure aloft will begin to build inland during the second half of the weekend, returning temperatures to near average values, perhaps marginally above by early next week.
Forecast: Mostly clear to occasionally partly cloudy through tonight. Increasing cloudiness Monday, leading to a chance of light showers by late afternoon. Light showers likely Monday night and early Tuesday morning. Becoming mostly to partly cloudy later Tuesday and Tuesday night. Mostly clear Wednesday and Wednesday night except remaining mostly cloudy in Kern County and southeastern Tulare County. Increasing cloudiness Thursday leading to a small chance of light showers late Friday through Saturday morning. Clearing Saturday afternoon. Mostly clear Saturday night through Sunday.

Two Week Outlook: April 17 through April 23: This model indicates temperatures will rise to at least marginally above average during this period. It also indicates that there will be a semi blocking ridge pattern in place, meaning the chance of precipitation is very low.
April: April is a transition month as we move from springtime weather to early summer weather at the end of the month. This model indicates above average temperatures over the southern half of the Golden State with near average temperatures over northern and central California. Precipitation will range below average.
April, May, June: This model shows above average temperatures over the Desert Southwest, stretching westward to California. With high pressure generally in control, expect below average precipitation…which doesn’t mean much now that we’re headed into the dry season.
Wind Discussion: There will be periods of winds mainly out of the northwest at 10 to 20 mph with stronger gusts through Monday night. Winds Tuesday through Wednesday will be mainly out of the northwest at 8 to 15 mph with stronger afternoon gusts.
Rain: Light showers will spread down the Sierra Nevada Monday with an increasing chance of light, scattered showers Monday afternoon into Tuesday morning. This will be a light precipitation event with most locations recording anywhere from a trace to .10. Highest amounts will be near the Sierra Nevada foothills. Dry weather will begin Tuesday afternoon and continue through Thursday. Model differences for a second system which will arrive Friday are significant. It, too, does not appear to be a strong storm but will have a chance for light showers Friday into Saturday.
Frost: As a cold storm sweeps through central California Monday through Monday night, a pool of cold air will settle to the bottom of the bathtub, so to speak, Tuesday through Wednesday. Blended model information spits out a low of 34 in Porterville Tuesday and Wednesday mornings. Using that as a base to go on, the traditionally cold spots could easily drop into the lower 30s with coldest locations at 29 to 30 for short durations. Most locations, however, will chill down to 33 to 38. Cloud cover and wind conditions should keep readings in the mid 30s to the lower 40s Thursday and Friday with above freezing temperatures thereafter.
