KTLA weather: Warmest day of the week
This morning, weak offshore winds have pushed away the marine layer, leaving skies mostly clear. Today will be the warmest day of the week. Temperatures will climb to the mid-70s in Los Angeles and to near 80 degrees in the warmest valleys. This afternoon, onshore breezes are forecast to return, which will allow the marine layer to re-establish itself overnight.
Wednesday morning, low clouds and fog will spread inland as an eddy circulation builds over the coastal waters. This will be the beginning of a cooling trend that will culminate on Friday. A series of weak weather systems will ride the jet stream through the interior West. This is going to strengthen the onshore flow locally and allow for partly cloudy conditions to return, especially near the beaches. Temperatures will top out mostly in the high 60s and low 70s.
Thursday night and Friday, a stronger trough will shift into Central California. A rapidly deepening marine layer combined with this trough could produce some light rain or drizzle Friday morning.
