Related: About this forumSLEET in the 50s?
We have something very weird happening in the DC area on this Friday. We are seeing sleet with temps from 50-55 degrees. How is this possible? There's an unusual dry layer a few thousand feet up. We *think* droplets passing thru it are freezing due to evaporational cooling.

I don't think you can have sleet with temps that high. Is it coming down in connection with a thunderstorm?

Sleet occurs when a snow flake partially melts and then refreezes. For partial melting to occur, the maximum temperature in the melting layer is typically between 33.8 and 37.4°F (1 and 3°C) and for a relatively thin layer (less than 2,000 feet thick).
