SYNOPSIS

06/440 PM.

Moderate to strong Santa Ana winds will continue through Sunday, with widespread gusty conditions expected across much of Los Angeles and Ventura Counties on Saturday. Temperatures will warm through the weekend, with widespread highs in the 80s. Briefly cooler conditions are likely early next week, with another warm and dry spell expected to start on Wednesday.

LONG TERM (TUE-FRI)

06/157 PM.

Tuesday will likely be the coolest day of the upcoming week. Onshore flow will return to the region and coastal clouds will be possible during the morning. Expect highs to mostly be in the low 70s for most coast and valleys, though this will still be a few degrees above normal. On Wednesday, high pressure will start to build over the coastal waters to the east and offshore flow will redevelop from the north. This will yield a dramatic warming trend, bringing many valley area into the 80s. Late this week offshore flow is favored to continue and 500 mb heights will continue to build. By Thursday and Friday, another heat spell is expected to be underway with many temperatures in the upper 80s and lower 90s. Highs will be near calender day records, and we will continue to monitor the need for Heat Advisories. Rain is not expected for the foreseeable future, however there are indications that heat will continue well into next week through the middle of the month.
