Tuesday we had beautiful conditions with highs above average primarily in the mid 60s to low 70s with the warmer temperatures inland and the cooler temperatures along the coast where there was more cloud cover. Tuesday night low clouds and patchy fog are returning. Lows will be in the low 40s inland and upper 40s along the coast.
The onshore flow combined with a weak impulse moving through the area tonight will likely lead to widespread night through morning marine layer stratus over the coasts. High resolution models indicate a weak eddy developing overnight which will likely deepen the marine layer and may push clouds in. By Wednesday afternoon skies will be clear but with continuing onshore flow expected, temperatures will cool a couple degrees.
There is a chance of low clouds again Wednesday night into Thursday morning, but models are indicating that offshore flow may keep it off the coast. Thursday temperatures will warm across coastal areas to the low to mid 70s.
On Friday, a closed upper-level low over the Pacific Ocean will approach southern California. Cloud cover will increase and temperatures will cool a few degrees. It will likely remain dry, but the southerly flow ahead of the low may produce some drizzle. The chance of showers will be possible through Saturday. Precipitation amounts will be very light, in general expecting less than 0.10 inch.
Sunday we should dry out with temperatures rebounding back above average.
