Pressure and weather in Buckeye
Buckeye sits at the western end of the Salt River Valley on the flood plain of the Gila River, in the lower Sonoran Desert at around 900 feet, with the White Tank Mountains to the northeast and open desert running west toward the Colorado River. It is one of the hottest and driest places in the United States, and it is far enough from the Pacific and any mountain barrier of consequence that its weather is dominated by heat itself. Barometric pressure here behaves unlike almost anywhere else in the country. Through late spring and early summer the desert heats so intensely that a thermal low forms over the lower Colorado River basin, and current barometric pressure sits genuinely low for weeks at a time with no storm anywhere nearby — a pressure signature produced by temperature rather than weather. That thermal low is also the engine of the North American monsoon: once it establishes and moisture is drawn up from the Gulf of California and the Gulf of Mexico, typically from early July into September, afternoon and evening thunderstorms erupt over the mountains and collapse outward across the valley floor as gust fronts and dust storms. The pressure jump under an approaching outflow boundary can be abrupt, several millibars in minutes, and it is the sharpest routine change of the year. The cool season is quieter: Pacific storms and occasional cutoff lows drifting in from California bring modest falls and the region's other rainy period, mostly December through March. October, November, April and May are the calmest and clearest months. A barometric pressure forecast for Buckeye matters most in monsoon season.
What this means for you
Can barometric pressure cause headaches? The desert Southwest is unusual in that heat drives the barometer directly, so long low-pressure stretches occur under blazing clear skies with no storm involved. Monsoon outflows then add very fast short-lived spikes on top. Both patterns catch people out. Use this barometric pressure forecast with Pressure Pal as a migraine tracker app to see pressure change today and watch for monsoon outflow boundaries.
