Area Forecast Discussion National Weather Service San Diego CA 315 AM PST Sun Jan 19 2020

SYNOPSIS. High pressure aloft and offshore flow at the surface will bring a warm day today. Monday through Wednesday will turn a little cooler with more clouds and perhaps a light shower or two. High pressure building aloft later this week will bring dry, warmer weather back the area Thursday through Saturday.

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

High pressure aloft and weak to moderate offshore flow at the surface will bring warm weather today. 500 mb heights this morning were 580 dm, which is 10 dm above average. Warming will also be aided by offshore flow from a 1040 mb surface high over eastern Utah. This Santa Ana surface pattern will generate gusty east winds in the mountains, foothills and valleys today, and the warm downslope flow west of the mountains will push high temps well into the 70s in the coastal and valley zones.

The highest wind gusts through 3 AM today included 42 mph at Pleasants Peak in Orange County, 40 mph at Sill Hill in the San Diego County Mountains, 39 mph at Highland Springs near the San Gorgonio Pass, and 37 mph at Rialto below the Cajon Pass. Peak gusts in these areas today will be around 50 mph.

High clouds will increase tonight ahead of a longwave trough over the eastern Pacific that will slowly march eastward across CA through Wednesday. This is a weak trough with limited instability, but it does have a deep moisture profile, so there may be a few light showers or sprinkles at times with any of the weak shortwaves rounding the base of the trough. The clouds and lower heights will bring cooling, most notably in the coastal and valley zones Tuesday and Wednesday when cooler marine air and marine layer clouds return.

On Thursday and Friday another ridge builds along the West Coast for dry, warmer weather through next weekend. Beyond next weekend the ensemble members suggest a stronger trough moving ashore along the West Coast which will be our next best chance for appreciable precipitation.

AVIATION. 190945Z . VFR conditions with SCT-BKN high clouds AOA 20000 ft through tonight. Locally gusty northeast to east winds of 25-30 kt expected through passes and over the mountains through this morning.

MARINE. An incoming NW swell will generate wave heights of 6-8 ft Wednesday into Thursday morning. Wave heights will be highest in the far southwestern portions of the Outer Waters, south of San Clemente Island. Otherwise, no hazardous marine conditions are expected through Thursday.

SKYWARN. Skywarn activation will not be needed today.

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.
