SYNOPSIS

02/753 PM.

Onshore flow will continue to bring low clouds to the coasts and coastal valleys each night through morning period. Weaker onshore flow will mean decreasing clouds in the valleys and gradually warming temperatures. Expect a return to near-normal temperatures by middle of next week with 80s and low 90s for many valley locations by that time.

LONG TERM (MON-THU)

02/1214 PM.

Temperatures will continue to trend warmer during the extended timeframe due to rising pressure heights, weaker onshore flow and a resultant thinner marine layer. 500 mb ensembles suggest that high pressure will strengthen and take firm hold of our weather pattern come later next week. While temperatures will largely still be near to below normal heading into next week, valley temperatures will warm into 80s and low 90s throughout the week. There is approximately a 50 to 60 percent chance that coastal locations, such as Santa Barbara, will warm to around or just above normal by Wednesday. If heat risk becomes a concern, it will be around this timeframe as there is little to no concern of heat risk prior to the middle to end of next week.

high confidence in KWJF and KPMD.

Low confidence in the remainder of TAFs. There is a 40 percent chc of no clouds at KSBA and a 40 percent of IFR cigs at KBUR and KVNY 12Z-17Z. The remainder of TAF's cig timing could be off by as much as 3 hours and there is a 30 percent chc of IFR cigs where low MVFR cigs are forecast. Very low confidence in CLD fcst aft 04/03Z.

KLAX...Low confidence in TAF. Low clouds could arrive any time between 09Z and 13Z. There is a 30 percent chc of OVC008 conds through 16Z. VFR conds could arrive as early as 1730Z or as late as 2030Z. Very low confidence on low cloud return timing aft 04/02Z. No significant easterly wind component is expected.

KBUR...Low confidence in TAF from 10Z-17Z with a 40 percent chc of OVC008 conds. High confidence for the rest of the time.
