Winter Weather February 22 to February 24
A cold core low pressure brought low elevation snow, gusty winds, and thunderstorms to California.
|
A very deep and cold upper-level low pressure system settled over the Bay Area and Central Coast the last week of February 2023. This unusual storm system brought a wide variety of impactful weather to the region: gusty winds, cold temperatures, low snow levels, and thunderstorms with hail and lightning. A cold front moved through the region on Tuesday, February 21, ushering in the first change to the airmass. Not only did the temperatures drop on Tuesday, but very gusty northwest winds developed behind the front and lasted into Wednesday. Instability also developed behind the front, which led to scattered showers Tuesday and Wednesday. Given the colder airmass some of the showers fell as snow over the higher peaks. The dynamic weather continued through the rest of the week as a very cold and deep cut off upper low moved directly the Bay Area. The upper low brought a re-enforcing shot of colder air and increased instability. The colder aided in lowering snow levels even further and in some areas below 1,000 feet, which is unusual. It’s common for the Bay Area to see snow several times a year over the higher peaks, but anytime it’s below 1,000 feet it’s more unusual and impactful. In this case, impacts were rather notable with Highway 17 near the Summit and Highway 128 near Cloverdale closing due to snow covering the roadway. A few weather spotters in the North Bay near Cloverdale reported snow down to 200-400 foot elevations. Mt Hamilton received over one foot of storm total snow and Los Gatos fell short of a foot at 11 inches of storm total snow. As for the instability, thunderstorms developed February 23-24, bringing brief heavy rain, gusty winds, lightning and enough small hail to cover the ground in places. The graphic below shows that numerous Special Weather Statements and Special Marine Warnings were issued to highlight hazards with developed storms.
