Pressure trend
The rate of change, not the absolute reading, is what actually forecasts weather.
Slight deterioration possible.
How this was calculated
- Method
- least-squares slope, not endpoint difference
- Samples
- 333
- Window
- 2.99 hours
- Rate
- -0.5292 hPa/hour
- 3h equivalent
- -1.59 hPa
- Bands
- WMO / Met Office 3-hour descriptors
A regression over all samples in the window is used because endpoint differencing on 30-second BME688 data is dominated by sensor noise and flips sign constantly.
National Weather Service
Official forecast for this grid square
Haze and patchy smoke before 1pm. Partly sunny. High near 84, with temperatures falling to around 77 in the afternoon. South southwest wind around 5 mph.
Ask the station
You are talking to a bot. It answers only from this station's readings and a cached National Weather Service forecast — it has no information about roads, fires, or health, and it will say so. Terms and disclaimers.
Hello. I am a small language model bolted to a barometer on a cabin roof at 4,767 ft. I can tell you what these instruments have measured, what the National Weather Service expects, and how the station works.
I cannot help with roads, fires, evacuations, or whether the air is safe to breathe — for those I will point you at people who actually know.
Answers are generated automatically and can be wrong. Not official weather information. In an emergency call 911.

Plotted together because the gap between them predicts fog and frost.

Sea-level pressure
Reduced to sea level per the WBAN procedure, so it is comparable to any forecast you read.
