Someone correct me if I'm wrong but the last time the inner burbs/DC really did well in a sleet bomb was like... March 2018? Or was that 2017? I recall playing with my kid in a thick crust of pellets.
Anyway, I'll believe the ice accums when I see what temps are around my neck of the woods on Friday during the day.
Trying to head out of town Sat AM... will be a slushy passable mess by then on our always busy roads, I'm sure.
