Area Forecast Discussion . UPDATED National Weather Service Los Angeles/Oxnard CA 1148 PM PDT Tue Jul 7 2020

SYNOPSIS. 07/515 PM.

Low clouds are expected for some coastal areas tonight, mainly the Central Coast and L.A. Coast. Temperatures will be a little cooler Wednesday, especially for areas that see more coastal clouds. High pressure will build over the region late this week and through the weekend, bringing very warm and dry conditions to the area with elevated fire weather conditions.

SHORT TERM (TUE-FRI). 07/803 PM.

***UPDATE***

West winds in the Antelope Valley are gusting up to 35 mph, with northerly wind gusts 35 to 40 mph along the western Santa Barbara South Coast near Gaviota. Otherwise, the only forecast issue for the overnight period is the marine layer clouds. Expecting slightly more coverage of low clouds along the coast, except for the SBA South Coast where northerly winds will keep the area clear. There is a possibility that low clouds could affect a small portion of the coastal valleys, but this is low certainty. After tonight, a shallower marine layer is expected as high pressure builds over the area.

***From Previous Discussion***

12Z models in good synoptic agreement through the short term period. At upper levels, broad cyclonic flow will persist through Wednesday then high pressure will begin to strengthen around the Four Corners area. Near the surface, weak to moderate onshore flow will prevail with a bit of northerly offshore gradient tonight.

As for temperatures, Wednesday will be the coolest day in the short term. With less marine influence and rising thicknesses and H5 heights, a warming trend is on tap for Thursday and Friday. Wednesday and Thursday. In fact by Friday, most coastal valley locales will be in the 90s with temperatures around 100 across interior valleys and the deserts.

As for winds, no major issues anticipated. With lingering northerly offshore gradients tonight, some locally gusty north winds can be expected across the Santa Ynez Range and I-5 Corridor. Otherwise, just typical onshore winds are expected each afternoon/evening, strongest across interior sections.

LONG TERM (SAT-TUE). 07/145 PM.

For the extended, 12Z models are in very good synoptic agreement. At upper levels, 600 DM high develops near the Four Corners area Friday/Saturday then slowly weakens Sunday/Monday. Near the surface, weak to moderate onshore flow will continue.

Forecast-wise, main story for the extended will be the heat. As the upper level high builds, temperatures will be on climb. At this time, it looks like Saturday/Sunday will be the warmest days with coastal valley locales in the mid 90s to around 100 degrees with low 100s across interior sections while overnight low temperatures remain on the warm side. On Monday/Tuesday, temperatures will cool as ridge weakens, but still will be quite warm. Looking at the Heat Risk grids, there may be the need for some non-routine heat products in some areas Saturday/Sunday. So, will need to monitor this potential closely over the next few days.

Otherwise, secondary concern will be the potential for some influx of monsoonal moisture. At this time, models look to keep any potential monsoonal moisture and showers well south and east of our forecast area. However, this will also need to be monitored closely. So, will go with mostly clear skies through the weekend, but would not be surprised to see some partly cloudy conditions this weekend (especially over Los Angeles county).

AVIATION. 08/0647Z.

At 0600z at KLAX . The marine layer was near 1000 feet deep. The top of the inversion was near 2600 feet with a temperature of 24 degrees Celsius.

MARINE. 07/749 PM.

For the Outer Waters . Gale force winds are expected to continue through late tonight, followed by Small Craft Advisory (SCA) conditions Wed/Wed night.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
