The holiday weekend is off to a great start, weather-wise! Although temperatures were on the hot side today just about everywhere. The morning low clouds were very limited to the immediate coast and lowest elevations of the inland valleys. ...We saw rapid clearing as the sun came up aside from some lingering fog in Monterey Bay in addition to high clouds from former Hurricane Marie, which also spread across some of the Central Coast. With that much sunshine early in the day, temperatures started to rise quickly. Surface high pressure over Oregon resulted in a tighter north-south pressure gradient that significantly weakened our onshore flow. With lighter flow and a shallow, well-mixed marine layer, temperautres soared well above the recent average.Temperatures at the coast were well into the 70s, some even approached 80. Inland temperatures were well into the 90s with several spots topping 100 degrees.
TONIGHT: Expect clear skies through most of the evening before midnight. Temperatures along the coast will fall into the low 60s and upper 50s with light onshore flow and mild water temps. Inland zones will fall into the middle to upper 50s. Low clouds and patchy fog will return once again but likely after midnight with minimal coverage confined to the immediate coast and Salinas Valley.
TOMORROW: Sunshine will prevail once again, even along the coast. The upper-level ridging backs off a little tomorrow, but light onshore flow hangs aournd and the marine layer will remain shallow. Thus, it will still be warm. Coastal zones will stick to the 70s. Inland zones will reach into the upper 80s to 90s.
EXTENDED: An upper ridge will build over the Eastern Pacific and again compress the marine layer and temperatures will stay warm for Monday and Tuesday. The trend is toward cooler from Wednesday into Friday as another trough moves into the Pacific Northwest. Any rain shower activity will stay well north of the Central Coast. Temperatures will continue their up and down trend for the next week.
The Outlook for the Central Coast for September 4th through September 12th, calls for Near or Above Normal Temperatures and Near Normal Rainfall...which is little or none this time of year.
