It was whatever you did, right before:
1:26 PM 34.8 °F 15.1 °F 44 % WNW 14 mph 14 mph 30.01 in 0 in 0 in 0.8 404 w/m²
1:36 PM 34.9 °F 13.5 °F 41 % NW 14 mph 21 mph 30.01 in 0 in 0 in 0.8 394 w/m²
And if you could remember, and post that answer here, then perhaps it would help someone else.
I had suggested:
Try rebooting the computer.
Try looking at the WeatherLink log file.
Did you do either of those things?
