Synopsis

Short Term

(Sun-Wed), 26/750 PM.

***UPDATE***

The main forecast issues for the immediate short term include a slight chance of light showers, mainly this evening over the mountains of Ventura and LA Counties due to some lingering moisture and instability. Little or no additional rain is expected. The rainfall totals with this storm varied quite a bit across the area. The highest totals were over the LA mountains with peak amounts between 1/2 to almost 1 inch, and around 0.40 inch for sites in the Santa Barbara mountains. The Central Coast had the highest totals near 1/4 inch. But as mentioned, many areas saw much lighter totals (under 0.10 inch) or no rain.

As for winds, breezy to gusty onshore winds affected many areas this afternoon, continuing into the evening, generally between 15 to 30 mph. There are no low clouds expected tonight, with scattered to broken clouds gradually breaking up overnight. Monday will be partly cloudy and warmer by around 3 to 6 degrees. Gusty onshore winds will repeat during the afternoon to evening hours. More significant warming is expected over the next couple of days, with highs peaking in the lower 80s by Wednesday. Low clouds may return to some coastal areas by Tuesday night into Wednesday, otherwise mostly clear skies are expected for midweek.

Long Term

(Thu-Sun), 26/220 PM.

Thursday the weak upper level low pressure system will sweep to the east, centered just south of of the Californa-Mexico border. A slight chance of showers will likely linger for Ventura and Los Angeles Counties on Thursday. Friday and Saturday, a weak ridge will yield warmer temperatures, though onshore flow will keep coastal low clouds and fog present during the mornings and overnight. Looking ahead, there are indications that another low pressure system may bring rain chances early next week (May 4-5th).
