Area Forecast Discussion National Weather Service San Diego CA 910 PM PDT Mon Jul 13 2020

SYNOPSIS. High pressure over the Southwest will continue to weaken and shift east this week, easing the heat across the region. Onshore flow will increase, further strengthening the westerly winds over the mountains and deserts and building the marine layer inland. Seasonally warm July weather will prevail for the remainder of the week with some extent of coastal clouds nights and mornings.

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

. Update .

All heat headlines have expired. The cooling trend will continue with temperatures getting back close to seasonal norms the next few days. The marine layer will be more established with cloudiness now along the coast moving into the inland valleys. No significant changes were made to the forecast this evening. See previous discussion below for more forecast details.

. Previous Discussion (Issued at 136 PM PDT Mon Jul 13 2020) .

The marine layer is back with its enabling buddy the coastal eddy. The cooling trend is underway, especially west of the mountains where temps at 1 pm are running 2-10 degrees lower than they were yesterday at this time. The desert is "cooling" as well, "only" up to about 111 so far, probably topping out around 115. The heat warning continues until 8 pm. Skies outside the marine layer will continue mostly clear, but there's a batch of higher clouds to the south off the Baja coast spreading clouds across San Diego County. Might be just enough to accent a pretty sunset and sunrise, but otherwise inconsequential. The strong upper ridge over the Southwest will continue to relent into Tuesday, allowing SoCal temperatures to actually dip below normal across most areas Tuesday through Thursday. A weak and intermittent coastal eddy will continue into at least Tuesday, helping our marine layer rebuild and extend low clouds into parts of the inland valleys during the early mornings through at least Thursday. Most model guidance shows the Southwest upper ridge to strengthen again Friday through the weekend, but only slightly. No big heat wave is expected, but temps will probably edge above average. Coastal clouds will not make it into inland valleys. Overall, pretty seasonal weather and coastal cloud coverage for mid July with temps fluctuating around normal.

AVIATION. 140315Z . Coast/Valleys . Areas of smoke/haze near downtown San Diego tonight. BKN-OVC010-015 at the coast this evening moving 25 miles inland through 14Z Tuesday. Moderate confidence of cigs ~700 ft MSL reaching KONT 12-16Z Tuesday morning with vis 3-5 miles in BR/HZ. Skies clearing back to the coast through 20Z.

Mountains/Deserts . A few high clouds and unrestricted vis through Tuesday. Southwest to west winds with sfc gusts 25-35 kt on the desert mountain slopes, below the passes, and into the deserts through this evening, and again Tuesday afternoon and evening.

MARINE. Increasing winds to 20 kts over the Outer Waters Tuesday afternoon and evening. Otherwise, no hazardous marine conditions are expected through Friday.

SKYWARN. Skywarn activation is not requested. However weather spotters are encouraged to report significant weather conditions.

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