Springtime snow on the mountains

An interesting cold front lingered over the Alexander Valley and its vineyards earlier this week. Geyser Peak (3,455 feet elevation) and the surrounding mountains were dusted with snow, high above the vineyards on the valley floor–most of which recently underwent budbreak. We were a little nervous about the buds being harmed by frosts, but luckily the air temperature in our vineyards hovered around 36-38 degrees, protected from the cold higher-elevation air by a thick fog layer. Our vineyard team is on high alert for potential cold fronts this time of the year, using electronic frost alarms that signal when potential threats arise. After the cloud cover disappeared, we turned on the wind machines last night when the temperature dipped to 35 degrees.
