Area Forecast Discussion National Weather Service San Diego CA 857 PM PST Mon Nov 30 2020

SYNOPSIS. A dry northwest flow pattern aloft will maintain fair and warm days and chilly nights through Wednesday with locally gusty northeast winds below passes and canyons. It will turn a little cooler for the latter half of the week as Santa Ana winds become more widespread. The very dry air will combine with the gusty winds to enhance fire weather conditions along and west of the mountains.

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

Skies are clear this evening, and unlike yesterday, few high clouds are on the horizon. The sfc pressure gradients are holding moderately offshore from the northeast, and NE wind gusts to around 30 MPH continue below the larger passes. Away from these areas winds were light and temperatures were headed south. The 00Z bone dry Miramar sounding was similar to yesterday afternoon, minus the easterly winds in the layer below 7K FT.

New model data continues the uncertainty regarding timing and strength of this upcoming Santa Ana. It is the developing block in the atmosphere over the West that is allowing numerical prediction to host a playground of solutions. Without the continuity of flow aloft, the various model schemes can fashion disparate solutions highlighting creativity at the expense of reliability. Consequently, this forecaster will pass on any forecast updates this evening.

From previous discussion .

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 during the latter half of the week will lead to increasing fire danger as vegetation/fuels continue to dry. 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. 010440Z . Locally gusty north to east winds of 15-25 kt will continue into Tuesday through the passes and near the foothills. Otherwise, mostly clear with unrestricted vis through Tuesday evening.

MARINE. Breezy east/northeast winds with gusts near 20 kt possible Thursday and Friday afternoons near the San Diego County coast, mainly near San Onofre, between Carlsbad and Del Mar, and near Imperial Beach.

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 pockets of near critical fire weather conditions below the passes due to northeast wind gusts of 25-35 mph.

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 the potential is there starting late Wednesday night and continuing into Saturday,for an extended period of critical fire weather conditions from the mountains westward across the valleys. Strong winds with gusts of 35-50 mph are likley in the wind-prone coastal slope and pass areas, and could be more widespread depending on how the system develops. For now, the greatest potential seems to be centered around Friday. Increasing moisture from the southeast may ease the threat by the weekend. A Fire Weather Watch has been issued for the Wednesday night through Saturday evening.

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.

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.
