Pressure and weather in Fox Crossing
Fox Crossing sits on the high northern plains of Hill County, in open short-grass country north of the Milk River and only a few miles from the Canadian line, with the Bears Paw and Sweet Grass Hills breaking an otherwise enormous horizon. Two opposing forces define the winter. Arctic air spilling south from the prairies brings some of the highest sea-level pressures recorded on the continent along with extreme cold. Against that, the chinook arrives when westerly flow descends the lee of the Rockies, warming and drying as it sinks, and it can raise the temperature by tens of degrees within hours while the barometer moves just as fast. This part of Montana holds some of the most extreme temperature-swing records in the world for exactly that reason. Spring and early summer bring the year's rain and occasional severe storms off the high plains, and September is typically calm and clear.
What this means for you
Chinook events pair a fast pressure change with an extreme temperature swing, so two triggers arrive at once. A migraine tracker app logging both is the only way to tell them apart here.
