• Below average temperatures for most areas through mid week

Summer will be knocking at our door and the heat it brings is a certainty. But, spring needs to run its course and it will be very much in evidence this week.

Memorial Day will feature a repeat of the weekend. Low pressure all along the California coast is making certain of that.

The persistent marine layer could become deep enough to create drizzle or even light rain each morning through Thursday extending from the beaches and coastal plains to the mountains of Southern California. The best chance of rain ranges up to 30 percent on Wednesday and Thursday. Amounts could measure a few hundredths across the coastal plain to a few tenths in the mountains.

High pressure will be on the rise Friday and Saturday with warmer days in the valleys, mountains and deserts.
