Pressure and weather in Hanover Park
Hanover Park lies roughly thirty miles from the Lake Michigan shore, out where the old prairie begins and the lake has almost no say in the daily weather. What reaches this part of the region arrives from the west with little to slow it down. The consequence is that the north-west suburbs see the full strength of the systems that organize over Iowa and Missouri, and the severe season from late April through June dominates the local year. Squall lines and the occasional derecho cross in the evening, typically preceded by a rapid pressure fall through the late afternoon and followed by a sharp rise as the gust front passes. Winter is the other active stretch, with clipper systems crossing quickly and larger lows tracking up from the south bringing heavy snow every few years. Between those, the long stretches of high pressure in September and October give the steadiest barometer of the year.
What this means for you
The evening squall-line pattern means the sharpest changes tend to land between four and nine in the evening. Knowing that window helps if you get a pressure headache from fast swings.
