Sunny & Pleasant Mother’s Day
WEATHER STORY
Mother's Day will remain pleasant with plenty of sunshine. With the amplified pattern of a deep trough over the West and a ridge over the Pacific, we’ll be caught in between. This will likely lead to fairly seasonable weather but also windy conditions at times. The weather is expected to remain dry with the exception of any misty drizzle we can pull out of the low clouds.
FORECAST & ALERTS
***RED FLAG WARNING***
… for the Diablo Range in Santa Clara County extended through 6PM Tuesday.
Conditions have briefly moderated but offshore winds will gradually increase again Sunday night into Monday morning across the North and East Bay hills. The latest forecasts now suggest conditions will worsen Monday night into Tuesday morning as another burst of strong offshore winds develops in the hills. This will occur with very low humidity values and drought stressed fuels. Winds will ease through the day Tuesday but warm and dry weather will persist through the Tuesday afternoon burn period.
-The most dangerous time will be the overnight hours of Monday evening into Tuesday morning when another burst of strong offshore winds will impact the hills.
-Elevations below 2000 feet...northerly winds 10 to 15 mph with gusts up to 40 mph. Elevations from 2000 feet and above...northerly winds of 15 to 25 mph with peak gusts to around 50 mph and local gusts to 60 mph highest peaks.
-Humidity as low as 5 to 15 percent, driest Monday and Tuesday afternoon with little or no recovery Monday night.
- Temperatures in the 80s and lower 90s afternoon hours with nighttime lows 50s in the valleys and 60s in the hills where winds are strongest.
New ignitions will experience rapid fire growth.
A Red Flag Warning means that critical fire weather conditions are either occurring now...or will shortly. A combination of strong winds...low relative humidity...and warm temperatures can
contribute to extreme fire behavior.
Sunday (Mother’s Day): Mostly sunny with passing high clouds. Low clouds possible on the coast late. Slightly cooler, with highs in the 60s to low 70s on the coast and 70s-80s inland. Breezy to windy at times for most areas.
