==============================================================================
SYNOP: (NWS SAN DIEGO)
An approaching storm system moving in from the north today will bring showers and cool conditions to Southern California through Monday night. The storm could bring significant snowfall to the San Bernardino County mountains, especially in the Big Bear area. Onshore winds will strengthen tonight, becoming offshore Sunday through Tuesday as the storm moves to the southeast. Northwest flow will prevail for the remainder of the week with near normal temperatures, and another chance of light precipitation for next weekend.

KEY POINTS

· A storm system will move through the region Sunday through Tuesday,
bringing showers, mountain snow and gusty winds. Unfortunately, there is
still considerable uncertainty regarding rain and snow amounts.

· Changes since last briefing:

o A Winter Storm Watch is now in effect for the San Bernardino Mountains
from noon Sunday through 10 AM Tuesday.

§ Snowfall amounts: 2 to 5 inches, with higher amounts of 6 to 10 inches possible over eastern sections of the San Bernardinos, including Big Bear Lake.

§ Wind gusts: Wind gusts of 50 mph, possibly higher, on the mountain ridge tops and coastal mountain slopes of the San Bernardino Mountains.

Storm System Sunday through Tuesday

Moderate Confidence

A storm system will impact the region Sunday through Tuesday. Confidence is moderate on the timing of precipitation, but continues to be fairly low for precipitation amounts.

· What and Where: A cold winter storm will impact the region, bringing showers, mountain snow, and gusty west winds. Snow levels could be 4000 feet or lower at times (especially high desert of San Bernardino County
where snow levels of 3000’ or lower are possible). Gusty west winds will occur over the mountains and deserts tonight through Sunday morning, with peak gusts to 45 mph. Winds will quickly turn offshore Sunday night, with
peak gusts over 50 mph possible over the mountain ridge tops and coastal mountain slopes.

o Precipitation: ¼” to ½” is most likely (storm total), but higher amounts are possible.

o Snowfall: 2” to 5”, except 6” to 10” possible over the eastern portions of the San Bernardino Mountains, including Big Bear.

· When: Sunday through Tuesday morning.

_____

SUMMARY

A storm system will move through the region Sunday through Tuesday. Rain is expected, but mostly light to moderate amounts (¼ to ½”, locally higher). Snow in the mountains will likely occur, with amounts of 2” to 5” and higher amounts possible on the eastern portions of the San Bernardinos Monday through Monday night due to wrap around moisture. There is still considerable uncertainty regarding precipitation amounts. Some gusty west winds will occur in the mountains and deserts tonight through Sunday morning, with peak gusts to 45 mph. Winds will quickly turn offshore Sunday night through Tuesday afternoon, with peak gusts over 50 mph possible over the mountain ridge tops and coastal mountain slopes.

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A deep area of low pressure will dive over southern California today and close off which will bring cooler
temperatures, gusty north winds and scattered rain and snow showers. The best potential for widespread precipitation will be south of Interstate 40 Monday. The system will move away Tuesday leaving a dry pattern much of the rest of the week.
