Forecasters' discussion
From the National Weather Service office in LOX, issued 1 hr ago
Synopsis
20/805 PM.
Widespread rain will develop Wednesday and continue into Thursday with a chance of thunderstorms. A weak Santa Ana will develop in the storm's wake by the weekend for dry and warmer conditions.
Long Term (sat-tue)
20/129 PM.
A weak to low end moderate Santa Ana event is expected this weekend but much weaker than the last event. Temperatures should warm up quickly into the upper 70s and 80s most everywhere except for the mountains and deserts. Latest models are indicating peak winds between 30 and 50 mph, strongest in the LA/Ventura mountains.
Aviation
20/2049Z.
At 20Z at KLAX, there was no marine layer or inversion.
High confidence in VFR TAFs at KBUR, KVNY, KPMD, and KWJF.
Moderate confidence in IFR-MVFR conds at KSMX, KSMO, KLAX, & KLGB. Timing may be off +/- 3 hours with CIG height +/- 200 ft of TAF. There is a 25% chance for no low clouds.
Good confidence in TAFs for KSBP, KSBA, KOXR, and KCMA. There is a 15% chance for brief IFR-MVFR conds 20/12Z-17Z.
SHRA is expected for overspread most TAF sites between 12Z-22Z, earliest along the Central Coast to KSBA. There is a 10-20 percent chance of TSRA KSBA and north starting around 18Z.
Marine
20/216 AM.
Relatively quiet conditions are expected across the waters today, then a storm system will move into the coastal waters as early as late this evening. This system will impact the area through Thursday. While at this point it doesn't appear as though it will bring significant winds, there will likely be some enhanced southerly flow Wednesday, which may require SCAs to be issued (including nearshore). In addition to the enhanced southerly flow, boaters can expect rain and a chance of thunderstorms and isolated waterspouts. With any thunderstorm there is the threat of lightning, gusty and erratic winds, small hail, and choppy seas. As the system leaves the area Thursday, fairly widespread west to northwest SCA winds will impact much of the coastal waters, creating steep, choppy wind waves.
Then a weak to locally moderate Santa Ana Wind event is likely this weekend, with some localized SCA level gusts possible nearshore in favored areas nearshore adjacent to Ventura and LA Counties.
