Area Forecast Discussion National Weather Service San Diego CA 907 AM PDT Wed Jul 3 2024

SYNOPSIS
A long-duration heat wave will continue for the deserts through at least much of next week. Friday and Saturday are expected to be the hottest days for most areas with the only relief from the heat toward the coast. The marine layer will slow the warming near the coast with night and morning coastal low clouds spreading into the western valleys late each night.

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

The dominant synoptic-scale feature through the forecast period will be strong high pressure, currently along the California coast, slowly building in and becoming anchored over the Western US. This will favor an extended stretch of hot and dry weather across much of the Western US, away from the immediate coast line where marine layer low clouds each morning and daily sea breezes will keep temperatures relatively cool.

Highs today will be generally be 2-7 degrees warmer than yesterday’s highs, topping out 5-10 degrees warmer than average for early July. Temperatures tomorrow remain relatively steady, perhaps a degree or two warmer/cooler depending on location.
Friday and Saturday look to be the overall peak of this heat event, when highs along and near the coast top out 5-10 degrees above normal, while highs across all other inland areas range from 10-18 degrees warmer than seasonal average! Some areas in the Coachella Valley and San Diego County Deserts, as well as localized areas in the mountains and coastal valleys, look to set multiple daily high temperature records. Friday in Palm Springs will be an exceptional case, when the all-time daily high temperature record of 123 degrees will be challenged.

Despite the numbers and stats just provided, there will undoubtedly be at least a few thoughts and mindsets of, “70s and 80s along the coast and almost 100 inland isn’t irregular, it’s summer, just turn on the A/C,” the last of which isn’t an option for every coastal resident and certainly isn’t the case for outdoor workers and unhoused populations. It definitely isn’t an option if one’s A/C equipment fails. And, let’s be real. A bunch of folks are likely going to be outside for the holiday, in the heat, playing games, grilling, and drinking alcohol. All of this is a recipe for dehydration (not to mention sunburn) if you aren’t careful and mixing in a water here and there, as well as re- applying sunscreen. The fact of the matter is, heat is the most frequent cause of weather-related illnesses and deaths, and we have an abundance of it coming in. We’re gonna take this incoming heatwave seriously.

Excessive Heat Warnings remain in effect for all desert zones, and are likely to remain in place through at least early next week. Excessive Heat Warnings also go into effect for the mountains of San Bernardino/Riverside/San Diego Counties, the Inland Empire, and the San Diego County Inland Valleys on Friday/Saturday, while Heat Advisories are hoisted for Inland Orange County and the Santa Ana Mountains on Friday/Saturday as well. There will be a slight drop in high temperatures on Sunday, followed by a relatively steady high temperature forecast for early next week. Keep in mind, it’s still going to be rather hot, with highs each day topping out 5-10 degrees warmer than seasonal averages per latest latest NBM guidance and derived HeatRisk guidance. The aforementioned tools suggest that an extension of all heat warning/advisory products through more of next week very well may be warranted.

What must absolutely not be lost in this story are the overnight low temperatures in the deserts. Lows in the Coachella Valley and San Diego County Deserts look to routinely only fall into the middle to upper 80s overnight while the High Deserts see lows in the middle to upper 70s, providing little to no overnight relief and added stress on power grids.



AVIATION
031530Z
Coast/Valleys
Latest satellite imagery shows low clouds already eroding quickly west towards the coast. Reported bases this morning were 800-1300 ft MSL with tops to 1200-1700 ft MSL. Clearing to beaches will continue through 17Z. Low clouds returning with similar bases and inland extent after 05-08Z Thu.

Mountains/Deserts...Mostly clear skies with unrestricted VIS will continue through this evening. Local south/west winds near 20-30 kts at times through the San Gorgonio Pass and above the Cajon Pass 22Z Wed-06Z Thu.

MARINE
No hazardous marine conditions are expected through Sunday.

BEACHES
A swell of 2-3 feet from 190 degrees with a period of 16-18 seconds will build into SoCal today through the weekend, peaking Friday into Saturday. This will lead to elevated surf with breaking wave heights up to 7 feet, mainly on exposed south and southwest-facing beaches in Orange County. Rip and longshore current risks will be high as well now through next Monday.

FIRE WEATHER
The long-duration period of hot and dry weather across Southern California will aid in a persistent downward trend in both dead and live fuel moisture. As evidenced by the recent Kitchen, McCain, and numerous other fires, local grass fuels are cured and very available to burn. The primary factors limiting any more critical fire weather potential are a lack of strong winds (outside of the typical diurnally-driven winds) any given day, as well as live fuel moisture. In other words, there’s still plenty of green as opposed to brown vegetation in the trees and brush.
Live fuel moisture will, however, be steadily dropping/drying out as we head through the weekend and into early next week. This will increase the ability of larger fuels (especially dead/dry and brown fuels) like brush, chaparral, and trees to burn. Energy Release Components, which can be thought of as somewhat of an “available energy for a fire to burn,” are steadily trending upward toward the 40th percentile and expected to approach the 45th-50th percentile next week. In other words, fuels are finally drying out back to “normal” levels for July, after being below normal for so long following this winter’s precipitation.

With fuels becoming drier and more receptive to burning, residents need to exercise additional caution with this year's 4th of July fireworks. If possible, please leave the fireworks shows to professional displays where firefighting resources are likely already on site. Please also take extra caution to ensure that any grills are kept far away from any potential grass/brush that would be receptive to burning.

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