Radar
 |
| NWS Chicago Doppler Radar reflectivity loop from midnight through 4 a.m. CST of an intense lake effect snow band into far northwest Indiana. The individual circulation structures are mesovortices that had generated on sharp convergent winds and lake-induced instability. This helped to focus and intensify snowfall as well as winds into far northwest Indiana. Along the shore, a gust in excess of 50 mph was observed. The intense snowfall rates (likely over 2" per hour) combined with the high winds created temporary whiteout conditions. |
