Two forecasts, side by side. The National Weather Service runs
numerical models on a 2.5 km grid. This station runs century-old arithmetic
on one barometer. They disagree often, and the
scoreboard keeps an honest record of who was right.
From our own instruments
Zambretti outlook
Barometer only
Needs sea-level pressure, which comes from the BME688. That sensor is
not attached yet, so there is nothing to forecast from.
The wind vane is already online, so this forecast starts at full
strength the moment pressure arrives.
Tonight's minimum
Dew-point convergence
Needs outdoor temperature and dew point from the BME688 in the radiation shield. Not attached yet.
