My light snow has changed to sleet and rain despite being at 32.5 degrees with the 850 temps supposedly crashing. So much for me being able to nowcast. Once I changed over, I thought I'd stay snow.

When I lull I get sleet. When radar shows yellows I get sleet and fat flakes

I'm also hoping the bands (however big they are) start lining up more n-s. 

There has been a tendency so far for bands to enhance along the following lines - 

roughly Kensington to Waterloo, Ashburn VA to Ellicott City and a third one up near Comus and Damascus. Hopefully that can continue.
