Brisk Bay Breezes bring busts

The mountains and waterways of coastal California can lead to a need for microclimate forecasting. This seemed to be the case in Napa, where, sure, a ridge built in, but the southwest winds off San Pablo Bay, often gusting to 20mph, held sway. High temperatures never crossed into the 80s, despite there not being a single forecast lower than 81 degrees. As is typically the case when things skewed towards the low side, Weatherbug was the top forecaster, and it wasn’t particularly close.
