The development of the storm has changed but the result for central MD still looks the same. For now, I’m still thinking light snow should develop Saturday evening and continue into Sunday morning with accumulations from an inch in northern areas and 3″ in the areas closer to DC. Temperatures will be below freezing so Sunday morning may have some slick spots on untreated surfaces.
A coastal storm will form during the day on Sunday but right now it looks to be too far to the south to have an impact on central MD. I’ll update tomorrow afternoon on any changes.
