Pressure and weather in Gary

Passing Midwest lows and cold fronts drive regional pressure changes, particularly during autumn and winter. After a frontal passage, cold air crossing Lake Michigan can sustain lake-effect snow even while pressure is recovering.

What this means for you

A Gary diary should distinguish the initial front from the colder lakeshore conditions that follow it. Comparing both phases in a migraine tracker app may reveal more than marking the whole stretch as a single snow day.
