Marine Weather and Tide Forecast for Glendale, CA

.SHORT TERM (TDY-WED)...18/205 AM.

The marine layer is about 5000 ft deep and marine layer stratus covers much of the csts and vlys of LA and VTA counties. The low clouds should dissipate earlier than normal as the pressure grads shift offshore. There will be a 10 mb offshore trend in the E/W direction and this will help develop a Santa Ana wind event despite not much in the way of actual offshore flow or upper support. Most of the passes and canyons will have gusty NE winds but the advisory level gusts will be confined to the mtns. Almost all of the csts and vlys will see 4 to 8 degrees of warming today with max temps across the csts and vlys in the 70s and lower 80s.

There will be weaker offshore flow on Tuesday but it will hinder any attempt of the marine layer to reform with only the Long Beach area vulnerable to morning low clouds. Any canyon winds that do develop in the morning will be well under advisory criteria. The warming trend will continue with 1 to 3 degrees of warming expected across the csts; 3 to 6 degrees in he vlys and 5 to 8 further inland. The inland areas greater warming trend is due to the lack of cool air advection that will occur today. The max temps across the csts/vlys will be 4 to 8 degrees above normal.

Wednesday should be a sunny day with little or no marine layer stratus in the morning. It will be the warmest day for the csts and vlys as max temps there will warm another 1 to 3 degrees. Look for mid 70s to lower 80s across the csts and 80s in the vlys.

By the weekend there will be a strong enough onshore push to the W that will generate gusty near advisory level gusts in the western Antelope Vly and foothills. The increase in onshore flow and marine layer coupled with slowly falling hgts will bring about a 4 day cooling trend. Friday will have the most noticeable cooling of 4 to 6 degrees. By Sunday max temps will be in the mid 60s to mid 70s across the csts and upper 70s and lower 80s in the vlys. These max temps are 1 to 3 degrees blo normal.
