Pressure and weather in West Covina
The winter storm season brings pressure declines ahead of Pacific fronts and rises as they clear. Autumn Santa Ana episodes develop under inland high pressure and offshore flow, while summer heat can build beneath persistent ridging without a nearby rain-producing low.
What this means for you
A walk in the South Hills calls for a heat check even when current barometric pressure changes little. In your migraine tracker app, distinguish hot stable stretches from windy offshore episodes and winter storms to avoid grouping very different valley weather together.
