Pressure and weather in Woodridge
Woodridge sits on the till plain of DuPage County, roughly 40 kilometres southwest of the Chicago lakefront and just far enough inland that the Lake Michigan breeze front usually stalls before it arrives. Losing the lake's moderating influence means hotter summer afternoons and colder winter nights than the shoreline suburbs record, and it also means the weather here is governed almost entirely by what is moving across the continent. In the warm season the most consequential of those are mesoscale convective systems, organised clusters of thunderstorms that form over Iowa and Missouri during the evening and travel east overnight, arriving in the Chicago suburbs in the small hours with strong straight-line wind and an abrupt pressure jump at the gust front. Derechos of this kind have hit the area repeatedly. The cold season belongs to travelling lows: Colorado systems that lift northeast across Illinois with substantial snow and steep pressure falls, and faster Alberta clippers that bring less snow but a much harder pressure rise behind them.
What this means for you
Overnight storm complexes give Woodridge some of its fastest pressure changes, and they arrive while most people are asleep. Weather-sensitive people who wake with symptoms can often match them to those events by checking barometric pressure today against the previous night.
