Area Forecast Discussion National Weather Service San Diego CA 136 PM PDT Mon Jul 13 2020

SYNOPSIS. High pressure over the Southwest will 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, building the marine layer inland. After one more very hot day in the deserts, 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 .

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 leat 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. 132015Z . Coast/Valleys . Occasional brief SCT conditions may occur at the coastal terminals this afternoon. Otherwise, mostly clear with high clouds and VFR conditions through early evening. Areas of smoke/haze continuing near downtown San Diego and points northeastward through the afternoon/evening. Low clouds with bases 1000-1500 ft MSL will redevelop 02-04Z this evening in San Diego County, 04-06Z in parts of Orange County. High confidence on areal coverage but lower confidence on exact timing. The other story will be if these clouds make it into parts of the Inland Empire. Little higher confidence with brief cigs ~700 ft MSL making an appearance at KONT 12-16Z Tuesday morning.

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

MARINE. The outer waters will get breezy in the afternoon/evening on Tuesday and Wednesday, with maximum gusts that may locally approach 20 knots. 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.

SGX WATCHES/WARNINGS/ADVISORIES. CA . Excessive Heat Warning until 8 PM PDT this evening for Apple and Lucerne Valleys-Coachella Valley-San Diego County Deserts- San Gorgonio Pass Near Banning.

PZ . NONE.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
