What am I seeing?

Solid dots are actual station measurements. Dashed lines between dots connect reported readings; they don't mean pressure was measured at every minute. The dashed portion after the final dot is a provisional weather-model estimate.

Checking model information…

Estimates can be wrong or miss brief fluctuations. The app uses National Weather Service station data and Open-Meteo models. Ground-level pressure is modeled only. Not a diagnostic measurement.
