Pressure and weather in DeWitt
DeWitt sits astride the Looking Glass River in Clinton County, immediately north of Lansing and roughly in the geographic centre of Michigan's Lower Peninsula. Lake Michigan is about eighty miles west and Lake Huron a similar distance northeast, so the town is roughly equidistant from both and shielded from the heaviest lake-effect belts that hammer the western shoreline. That inland position still leaves it fully exposed to the parade of systems that cross the Great Lakes. In winter, Alberta clippers are the defining feature: fast-moving, moisture-starved lows that sweep down from western Canada, cross Michigan in a matter of hours and produce quick, sharp swings in barometric pressure with a bitter northwest wind and a burst of snow behind them. Larger Colorado and Ohio Valley lows arrive less often but with far deeper falls, sometimes changing precipitation type three times in a day. Spring is the second active season, when warm advection off the Gulf runs into cold air still lingering over the lakes and squall lines cross mid-Michigan with abrupt pressure drops. Summer is comparatively benign, dominated by weak ridging broken by afternoon thunderstorms. Anyone watching current barometric pressure here soon notices how frequently it moves. The winter half of the year is when a barometric pressure forecast for DeWitt matters most.
What this means for you
Can barometric pressure cause headaches? Mid-Michigan sees an unusually high number of separate pressure systems each winter, so the barometer here changes direction more often than in most parts of the country. Clipper passages in particular compress a full rise and fall into less than a day. Use the barometric pressure forecast in Pressure Pal, a migraine tracker app built to show pressure change today ahead of the next system crossing the lakes.
