Area Forecast Discussion National Weather Service San Diego CA 319 AM PDT Wed Jul 15 2020

SYNOPSIS. Through Thursday, a weak trough of low pressure over California will keep high temperatures west of the mountains a little cooler than average with night and morning coastal low clouds and fog extending inland into portions of the inland valleys. For Friday through the weekend, high pressure to the east will expand into southern California bringing a warming trend with high temperatures near to slightly above average for the weekend. For the early to middle part of next week, the high pressure will weaken slightly with the mid level flow becoming south to southeasterly. This could begin to direct some monsoonal moisture into southern California with some afternoon clouds over the mountains and with the lower deserts not quite as hot.

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

SHORT TERM (Today through Friday). Through Thursday, a weak trough of low pressure over California will maintain a deeper than seasonal marine layer with areas of night and morning coastal low clouds extending inland into portions of the inland valleys. High temperatures will be near average in the lower deserts, around 5 degrees below average in the mountains and valleys, and a few degrees below average elsewhere with high temperatures in the 70s for coastal areas, 80s to lower 90s in the valleys, and 105 to 110 in the lower deserts. High pressure to the east will begin to expand into southern California on Friday with high temperatures a few degrees warmer than Thursday.

LONG TERM (Saturday through Tuesday). High pressure will continue to expand across southern California during the weekend. The warming trend will continue into Sunday with high temperatures on Sunday near to slightly above average. The marine layer will become a little shallower with night and morning coastal low clouds and fog only extending inland into the western valleys.

For the early to middle part of next week, the high pressure will weaken slightly and shift northward slightly with the mid level flow becoming south to southeasterly across southern California. That would open up the possibility of at least some monsoonal moisture beginning to spread into southwest California.

Beginning early next week, there could be some higher level debris cloudiness at times and some afternoon clouds over the mountains with at least isolated afternoon convection possible over the mountains beginning around the middle of the week.

AVIATION. 150900Z . Coast/Valleys . Low clouds with bases 1500-2000 ft MSL and tops to 2300 ft MSL will continue to push into the inland valleys this morning, reaching KONT around 10-11Z. Visibility will lower to 3-5 miles in the valleys where clouds and terrain intersect. Scatter out expected in the valleys 15-16Z and along the coast from 17-18Z. Low clouds will return to coastal areas after 05Z Thursday with similar bases and inland extent.

Mountains/Deserts . Northwest winds will increase after 21Z in the mountain passes and into the desert floor, with gusts of 25-35 kts. Winds will diminish after 08Z Thursday. Otherwise, mostly clear with unrestricted visibility through today.

MARINE. No hazardous marine conditions are expected through Monday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . NONE. 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.
