  DAYS OF NO RAIN AT EAST HESPERIA: 26

 SYNOP:

Dry with weaker winds and a minor warming trend today and Wednesday. A low pressure system moving inland through California will bring cooling and strong gusty west winds in the mountains

and deserts Wednesday night into Thursday night. There is also a chance of light showers along and west of the mountains Thursday. Dry, warmer, and lighter winds for Friday into next weekend.

 Gusty north winds of 20-30 mph with gusts to 40 mph will continue across the transverse mountains extending from Santa Barbara County to northern and western Los Angeles County through the early morning hours. These winds will slowly ebb through the late morning hours before becoming light by early afternoon.  However, it will remain breezy across the desert, Owens Valley and the central coast where winds of 15-30 mph will be common throughout the day.  Skies will be clear across the entire district which will allow temperatures to warm into the upper 40s and 50s in the mountains to the lower 70s across the valleys of Southern California.  After another day of warming Wednesday, another cold, moisture-deprived system will move through the area Wednesday night into Thursday, bringing scattered showers.  Most areas will see under a quarter of an inch, but amounts will be highly variable due to the showery nature of the precipitation.  Snow levels will be down to 4,500 feet and a brief flurry may even be possible on some of the passes into Southern California Thursday morning.  Temperatures will drop back to a few degrees below normal and gusty north winds will be possible Thursday afternoon into Friday.  The weather this weekend looks warmer and much less windy with highs climbing back to near normal under sunny skies.  Another weak system will likely bring cooler, onshore flow back into the weather picture early next week.  No strong offshore winds are expected the next 7-10 days. 

NWS LAS VEGAS – (NORTH & EAST OF BARSTOW TO STATE LINE)

The entire southern Great Basin and Mojave Desert will

be much cooler today following a passage of a cold front. After a

quiet and warmer day Wednesday, winds will increase along with a

chance of showers and even a few thunderstorms Thursday and Friday

with next storm system. Dry and warmer weather returns Saturday

through Monday. 

CHANGES SINCE PREVIOUS BRIEFING

The region will be between storm system today and Wednesday. Our next storm will be moving into central California Wednesday night.

Forward motion of the system slows over the southern Great Basin and Mojave Desert THU-FRI allowing for a chance of rain/snow showers, and even a few embedded thunderstorms mainly north of Interstate 40.

 

FORECAST DETAILS

ERN CA/SRN NV/NW AZ

 

WINDS – THU

West-Southwest gusts 30-40 mph, corridor between Barstow and Kingman.

Northwest gusts 40-50 mph, Nrn. Inyo, Esmeralda and central Nye Counties.

 

WINDS – FRI

Northwest gusts 30-40 mph, Nrn. Inyo County east into Lincoln County.

 

PRECIPITATION

Timing: Primarily Inyo County and southern Nevada THU, spreading east into Mohave County THU NGT-FRI while tapering off in

Inyo County.

Total Precipitation Estimates:

Generally 0.10″-0.30″ above 5000 feet.

Generally less than 0.10″ below 5000 feet.

 

Total Snowfall Estimates:

Eastern Sierra Slopes Inyo County, 1-3″ 7000-9000 feet, 3-6″ above 9000 feet.

Lincoln County, 1-3″ above 7000 feet.

Spring Mountains, 1-3″ above 9000 feet.

 Fire Potential Discussion: Large fire potential will be low over most of the district. However, areas south and east of Los Angeles County are much drier and grasses have cured over most non-shaded areas due to the hot weather last Saturday.  These areas, especially in Orange and San Diego County, will see ignition components climb to high levels for this time of year Wednesday and again over the weekend due to sunny, warm weather.  Other areas may see some light IA due to windy conditions today and again later this week when the next storm arrives.  Out of region demand is expected to continue to increase the next couple of days due to very dry and windy conditions in the Southwest and on the high plains.   

SPECIAL NOTES:

Santa Ana Wind Season Outlook

Issued: Thursday, April 12, 2018

 

A fairly significant shift in the upper-air pattern occurred in March to allow for several periods of wet weather across Southern California. This shift brought slightly fewer than normal Santa Ana wind events to the region with 4 days (2) in the Los Angeles and San Diego areas respectively. The number of Santa Ana wind events has been decreasing since January and will continue to decline during the next couple of months.

Although sea surface temperatures continue to increase across the Equatorial Pacific region, La Niña conditions are still present. Most guidance suggests that SSTs will continue warming through the remainder of the spring and into the summer, with neutral conditions expected through late summer or early fall. The Pacific Decadal Oscillation (PDO) is slightly negative with probably only minor changes in SSTs occurring across the Central Pacific during the next few months. This, combined with our analog models would suggest a continuation of a near normal number of Santa Ana wind days for the remainder of April and also for the April-May time period. Normally for April the Los Angeles area experiences around 4 Santa Ana wind days, with an average of 2 days in the San Diego region.

While the end of Santa Ana season is nearing, the next six weeks, however, can be a crucial time as fuels begin to dry out, making them more receptive to fire.

The significant rains that occurred in March led to the development of a healthy grass crop over much of Southern California which is now starting to cure. Any Santa Ana winds that occur in May could result in an increase in large fire potential. Recall that in May 2013, the Camarillo Springs Fire occurred, and in May 2014, a significant fire outbreak developed over Northern San Diego County, both events were associated with late season Santa Ana winds.

 Summary:

While the PDO remains in a slightly cool phase, the Niño3.4 index is positive. Warming in the Equatorial Pacific region is expected through summer with neutral conditions anticipated later this summer and fall. Both the current weather pattern and our analog models suggest that there will be a near normal number of Santa Ana wind days for both the April and the April through May time periods. This time of year is often quite changeable so confidence in this forecast is moderate. Fuels will become more susceptible to fire in the coming weeks, so any significant winds that occur, especially in May, could result in significant fire activity.

 

BI-MONTHLY FUELS DISCUSSION

For Southern and Central California 

Updated: Thursday, April 12th, 2018

Next Routine Update: Thursday, April 26th, 2018

 

General Discussion:

An active weather pattern continued through the end of March and into early April as a series of troughs

entered the Pacific Northwest. These storms continued to bring significant rain to the northern half of the

state. Another “atmospheric river” type of precipitation event occurred the first week of April which resulted in high rainfall totals and high snow levels across northern California. The district was generally on the periphery of the precipitation, but cool, humid onshore flow kept fine fuels from drying too much during the past few weeks.

However, the far southern part of the state, generally south and east of Los Angeles County, have seen the first signs of curing. The next warm and dry period will likely bring extensive and rapid curing to these areas with fine fuels becoming available for ignition. These same fuel beds will see dead fuels drop back to below normal moisture levels toward the southern border by the end of the month. Therefore, fires will spread during warm or windy periods across the desert interface areas and intermediate valleys from Los Angeles County southward. Further north, a heavy, green grass crop will likely keep fires at bay outside the desert regions.

The next two weeks appear to offer a highly variable weather pattern with a 3-4 day vacillation between deep troughs and strong ridges. Temperatures will likely fluctuate accordingly with some light precipitation possible across the far northern part of the district. One or two weak offshore wind events of short duration will be possible through the last week of the month.

 SANTA ANA WILDFIRE THREAT INDEX: GREY NO RATING / 

NO RATING: Sundowner winds are either not expected, or will not contribute to significant fire activity.

 

MARGINAL: Upon ignition, fires may grow rapidly.

 

MODERATE: Upon ignition, fires will grow rapidly and will be difficult to control.

 

HIGH: Upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control

 

EXTREME: Upon ignition, fires will have extreme growth, will burn very intensely, and will be uncontrollable.
