SGP/EBBR/E4 - Wind Speed Cups Frozen

Freezing rain, snow, and below freezing conditions during 23 November

Plevna, KS.  On 24 November, the cups broke free of the ice and turned freely 
again. 

Measurements affected by the stalled wind speed sensor include:

5 minute:  wind_s, res_ws

15 minute: wind_s

30 minute: wind_s, res_ws
