Weather Summary

Lake effect cloudiness dominated the region yet again. The low to the north finally moved off the coast of Labrador, but it continued to pull cold winds over the relatively warm Lakes, producing lake effect clouds and leading to as much as a foot of snow over Northern Michigan.

Flight Summary

C3VP did fly over the CARE site and the nearby CloudSat overpass at around ~ 2:30 LT. There was a possibility for CLEX add-on flight time, but with nothing but lake effect clouds in the area, the decision was made to hold off for more CLEX-type clouds. Below is a MODIS IR image and CloudSat swath showing the targeted clouds and the satellites' overpass. More details of the C3VP flight will follow.
