Area Forecast Discussion National Weather Service San Diego CA 201 PM PST Mon Nov 30 2020

SYNOPSIS. Dry and seasonably warm days and chilly nights will prevail through Wednesday. Gusty northeast winds, especially late nights and early mornings will continue below favored passes and canyons, resulting in brief and localized near critical fire weather conditions. A long duration Santa Ana Wind may impact Southern California during the second half of the week, possibly beginning as early as Wednesday night and lasting into the upcoming weekend. This will produce widespread critical fire weather conditions over the mountains and inland valleys on strengthening east to northeast winds in a very dry airmass late this week.

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

-Forecast Highlights-

* Long duration Santa Ana Wind event possible Wednesday night through Saturday evening, leading to an extended period of critical fire weather conditions -> Fire Weather Watch Issued

* Dry with localized areas of near critical fire weather conditions precedes the Santa Ana event

* Dry with warmer than normal temps favored through mid December

The overall weather pattern through the end of this week and through at least the middle of next week will feature upper ridging off the California coast extending into the Pacific Northwest. This will continue to block storm systems, continuing the dry weather regime. Temperatures will continue to side on the warm side of normal.

This pattern is supportive of Santa Ana winds. In fact, a long duration Santa Ana Wind event is possible from Wednesday night through Saturday evening per GFS and EC ensembles. There continues to be model divergence and this leads to continued uncertainty. The trend the past few days has been to delay the strongest winds and now it appears that the peak may be centered around Friday. Northeast to east winds will increase with gusts potentially becoming widespread in the 30-40 mph range from the mountains and into the inland valleys, including inland Orange County, the Inland Empire and inland San Diego County valleys. Peak gusts of 50+ MPH could occur in the wind prone areas along the foothills, but populated areas most likely will stay below 50 mph. We will continue assess exact strength and timing as there continues to be rather large ensemble spread.

Dry air is already in place across SoCal even preceding this incoming Santa Ana. Dry air will continue over the area through Wednesday along with periods of localized northeast winds of 25-35 mph, leading to near critical fire weather conditions below passes and canyons, especially late Tuesday night through Wednesday morning.

Successive dry days along with the long duration Santa Ana incoming during the latter half of the week will lead to increasing fire danger as vegetation/fuels continue to dry.

Temperature wise, it will be warmest through Tuesday with slight cooling occurring Wednesday-Thursday then temps will be rather steady through the weekend, staying mostly on the warmer side of normal, though nights will continue to be chilly given the dry airmass and large diurnal range in temperatures continuing.

AVIATION. 302140Z . Locally gusty north to east winds of 15-25 kt will continue at times through the wind prone passes and canyons today and tonight. Otherwise, mostly clear skies with unrestricted vis will prevail through tonight.

MARINE. Breezy east/northeast winds with gusts near 20 kts possible Thursday and Friday afternoons for some areas just off the San Diego County coast. Otherwise, no hazardous marine conditions are expected through Friday.

FIRE WEATHER.

. Possible Long Duration Santa Ana Wind Event with Widespread, Critical Fire Weather Conditions Wednesday Night Through Saturday -- Fire Weather Watch Issued .

Elevated fire weather conditions will continue over the mountains and valleys through Wednesday as dry air remains in place. There will continue to be isolated locales near critical due to northeast wind gusts to 25-35 mph, mainly right below the Cajon Pass but in isolated foothill locales as well through Wednesday, especially late Tuesday night-Wednesday morning.

The overall weather pattern evolving for Thursday-Saturday will favor increasing winds with at least a moderate strength Santa Ana anticipated. There continues to be uncertainty in the exact strength and timing, but starting late Wednesday night and continuing all the way through the day Saturday, it is looking like an extended period of critical fire weather conditions for the mountains and valleys, including inland Orange County, the Inland Empire and the inland valleys of San Diego County. Strong winds with gusts of 30-50 mph could become quite widespread. Models continue to delay the peak in winds and today it is looking to be centered around Friday. A Fire Weather Watch has been issued for the Wednesday night through Saturday evening period.

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

SGX WATCHES/WARNINGS/ADVISORIES. CA . Fire Weather Watch from late Wednesday night through Saturday evening for Orange County Inland Areas-Riverside County Mountains-Including The San Jacinto Ranger District Of The San Bernardino National Forest-San Bernardino County Mountains-Including The Mountain Top And Front Country Ranger Districts Of The San Bernardino National Forest-San Bernardino and Riverside County Valleys -The Inland Empire- San Diego County Inland Valleys-San Diego County Mountains- Including The Palomar And Descanso Ranger Districts of the Cleveland National Forest-San Gorgonio Pass Near Banning- Santa Ana Mountains-Including The Trabuco Ranger District of the Cleveland National Forest.
