After looking at the latest forecast models, confidence continues to remain low in regards to how much sleet and or freezing rain falls from the Blue Ridge and Catoctin mountains eastward toward the western suburbs of Baltimore and Washington. “The Devil is in the Details” and there will be a lot of “now-casting” going across these areas as everything will depend on temperature profiles. I’m most concerned about today’s freezing rain potential (more below).
