Where this comes from

Nothing on this page is fetched from the internet. My station (KO6HXC, Northern California) receives the National Weather Service's EMWIN text and chart broadcast straight off GOES-18's radio downlink with a dish and a software-defined radio, then filters it to my own forecast zones.

The conditions above come from the automated weather station at Lincoln Regional airport (KLHM), about 5 km west of me — the nearest station that reports, roughly every 20 minutes. The "nearby" readings come from the Sacramento office's hourly regional roundup, so they are usually a little older; both are stamped with their own time. That airport station has no rain gauge, which is why nothing here reports rainfall in any weather.

"No cloud below 12,000 ft" is not the same as a clear sky — it is the limit of what the airport's ceilometer can see, so that is how it is written. The charts are national or regional products that happen to include northern California; none of them is centred here, and each one is labelled with how old it is, because they refresh at wildly different rates.

The weather symbols are Weather Icons by Erik Flowers, from designs by Lukas Bischoff, under the SIL Open Font License 1.1. They are served from this host, like everything else here. A symbol is only ever decoration — the words beside it are what the station actually received.
