Featured Article CSU-CHILL X-Band (9 GHz) reflectivity data observed in an extensive snow band on 15 April 2013. Beam intersection angles between the CSU-CHILL and NWS KFTG radars were large enough to permit dual-Doppler wind syntheses to be done in the vicinity of the intersecting red lines. Selected dual-Doppler and CSU-CHILL X-Band RHI plots of the snow band data have been assembled. more

Featured Image Steam Devil Intense sunshine around mid-day on 23 April 2013 caused the rapid sublimation / melting of several inches of snow that had fallen overnight. Condensation produced a widespread layer of "steam fog" just above the moist surface of a plowed field immediately south of the CSU-CHILL radar. On several brief occasions, the intense surface-based thermal instability caused the fog layer to organize into rotating "devils". Photo credit: Pat Kennedy More featured pictures...
