Area Forecast Discussion National Weather Service San Diego CA 831 AM PDT Sun Aug 9 2020

SYNOPSIS. A weak trough along the California Coast will keep seasonally dry and warm Summer weather in place through midweek. The trough will be replaced by a building ridge over the Southwest later this week, bringing a warming trend that will create heat wave conditions inland by next weekend. Onshore flow should still moderate coastal areas, but even there, temperatures will likely be above average.

DISCUSSION. FOR EXTREME SOUTHWESTERN CALIFORNIA INCLUDING ORANGE . SAN DIEGO . WESTERN RIVERSIDE AND SOUTHWESTERN SAN BERNARDINO COUNTIES .

Marine stratus was widespread this morning offshore and extended inland up to 25 miles over western San Diego County. Much of northern O.C. was clear. Inland, skies were clear. The 12Z Miramar sounding had a 8C inversion based near 1550FT with light and variable winds up through 15K FT. Weak onshore sfc pressure gradients were sufficient for westerly winds of 15-20 MPH and gusts 30-35 MPH through the San Gorgonio Pass. The cloud deck is fairly thin and should burn off quickly this morning. The forecast looks on track.

A weak trough along the CA Coast will maintain fair and seasonally warm Summer weather early this week with areas of night and morning low clouds extending into the western valleys. By midweek, a transition to warmer weather will be underway as the trough weakens and a ridge of high pressure builds over the Southwest. By next weekend, a strong high pressure center aloft will be centered over the Lower Colorado River Valley. Daytime temperatures then could be ten degrees Fahrenheit or more above average over the valleys and deserts. Onshore flow should maintain moderate conditions over coastal areas based on the current forecast pattern, but a shallow marine layer will increase the chances for areas of dense fog later this week.

Some high-level moisture may get pulled over the region around midweek, otherwise fair and dry conditions will prevail into next week with areas of coastal low clouds and fog at times.

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