Forecasters' discussion

From the National Weather Service office in LOX, issued 2 hrs ago

Synopsis

21/227 AM.

Widespread rain will develop later today 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)

21/227 AM.

Weak ridging and weak (1 to 3 mb) offshore flow from both the east and north will be in place for the entire xtnd period. The best upper level support will be on Saturday when there will be 30 to 40 mph gusts csts/vlys and as high as 50 mph in the mtns. The winds will be weaker starting Sunday.

High pressure and offshore flow should keep the skies clear.

There will be decent warming on Saturday (4 to 6 degrees) and then 1 or 2 degrees of extra warming Sun and Mon. Tuesday will cool some as the ridge and offshore flow weaken substantially. Cst/Vly temps will be a little above normal while the interior will be several degrees blo normal.

A quick look at the AI long range models shows dry conditions through the end of the month.

Aviation

21/0858Z.

At 0832Z at KLAX, there was no marine layer nor an inversion.

High confidence in VFR TAFs at KPMD and KWJF.

Moderate confidence in non desert TAFs through 17Z with a 30 percent chc of intermittent MVFR cigs.

Moderate confidence in all non desert TAFs after 17Z. Rain timing could be off by +/- 2 hours. There is a 40 percent chc that there will be MVFR cigs/vis with the rain.

There is a 10-20 percent chance of TSRA KSBA and north starting around 18Z. The chc of TSRA will then spread to KOXR and KCMA Wednesday afternoon, and into LA County after 03Z.

Marine

21/230 AM.

Expecting showers to continue moving into the coastal waters this morning as the low approaches from the west. Boaters can expect rain and a chance of thunderstorms and isolated waterspouts spreading from western waters to southeast. With any thunderstorm there is also the threat of lightning, gusty and erratic winds, small hail, and choppy seas. Winds still do not look too impactful, there is a good chance for periods of Small Craft Advisory (SCA) level (including the nearshore waters) southerly winds this morning through this evening. 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.
