Area Forecast Discussion National Weather Service San Diego CA 902 PM PST Mon Jan 27 2020

SYNOPSIS. High pressure aloft and weak offshore flow will keep Tuesday mild, with clear skies. Moderate to strong Santa Ana winds then develop Wednesday, peaking Wednesday night, and subsiding Thursday afternoon. Wind Advisories and High Wind Watches have been posted. Temperatures will continue to climb as we head into Friday and Saturday as a ridge builds rapidly from the west, with widespread temperatures in the 80's likely for coastal and valley locations along with continued mostly weak offshore winds. A passing shortwave will bring a sharp drop in temperatures and a transition to onshore flow starting Sunday, with a slight chance of light rain Monday.

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

UPDATE.

The forecast was updated this evening to increase wind strength for the Wednesday through Thursday Santa Ana event, as recent guidance continues to suggest the potential for locally strong winds, particularly in our northern zones. Forecast 850 mb winds peak between 50 and 60 kt on the leeward side of the San Bernardino Mountains with northerly flow favoring Cajon Pass and adjacent foothills. GFS and ECMWF guidance suggests San Diego to Tonopah pressure gradients peaking between -10.5 and 12.5 Wednesday night, when the strongest winds should occur. Maximum gusts of 55 to 60 mph are expected for most foothill locations (closer to 40 mph for Orange County foothills), and isolated gusts of 65 to 70 mph at our traditionally windy locations such as Fremont Canyon, Highland Springs and below Cajon Pass. High Wind Watches and Wind Advisories have been posted for Wednesday and Thursday.

In addition a few upward adjustments were made to the high temperature forecast, primarily for areas west of the mountains through Saturday. Offshore winds will help maintain quite mild conditions west of the mountains overnight Wednesday and provide a head start on Thursday. Come Friday and Saturday, highs in the mid 80's look likely for many inland valley locations as a strong ridge builds in rapidly from the west.

PREV DISCUSSION. /TAEGER, ISSUED 129 PM/

Marine clouds were widespread over the CA Bight and extended inland up to 15 miles early this morning. Some fog was reported inland as well, but not as thick or widespread as last night. The sfc pressure gradients were quite weak but had a weak onshore trend over the past few hours. wind reports were weak overall with the strongest gusts only around 15 MPH from the south in the San Bernardino Mts.

A weak ridge over SoCal this morning will be replaced by a passing weak trough later today. This will help to bolster the onshore flow across the mts/deserts, and deepen the marine layer a bit more through tonight. Weak ridging aloft follows for Mon/Tue with some offshore flow through the passes, but there is one final trough to make it past the SW before a sustained dry, Santa Ana type weather pattern develops under a building ridge off the EastPac. This will be accompanied by a noticeable warming trend, and periods of gusty offshore winds near the foothills for the latter half of the week. By Saturday, daytime highs could be running some 10-15F above average.

Major pattern differences develop beyond next weekend in the 00Z operational ECMWF/GFS runs, so confidence decreases with regard to temperatures, but both models and there ensemble members show little consensus for development of any meaningful precipitation over most of California well into next week.

AVIATION. 280347Z . Mostly clear with unrestricted visibilities most areas. Winds generally light through Tuesday.

MARINE. No hazardous marine weather is expected currently through Friday, although north winds will increase Wednesday and could produce choppy and hazardous conditions. These winds will decrease early Thursday morning.

BEACHES. Elevated surf and strong rip currents will continue this week. Surf approaching 7 feet in San Diego County mainly Tuesday.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Wind Advisory from 4 PM Wednesday to 4 PM PST Thursday for San Diego County Mountains.

High Wind Watch from Wednesday morning through Thursday afternoon for Riverside County Mountains-San Bernardino County Mountains-San Bernardino and Riverside County Valleys-The Inland Empire-San Gorgonio Pass Near Banning- Santa Ana Mountains and Foothills.

Wind Advisory from 4 PM Wednesday to 1 PM PST Thursday for Orange County Inland Areas.

PZ . NONE.
