A Winter Storm Watch has been issued as close as Frederick County. The reason MoCo is not yet under anything is because a Watch is issued when there is confidence for 5 inches or more. As of now, the National Weather Service has most of MoCo in the 4-5″ range, with a south/east MoCo in the 3-4” range, and Upper MoCo in the 5-8’”range. The Watch areas will likely turn into Winter Storm Warnings, and we can easily see a Watch put in place later today, especially for Upper MoCo if the confidence for more snow is there. Either way, I suspect at least an Advisory for all of MoCo.
Fox 5 has weighed in with its First Call Map and approximately 2/3 of MoCo is in the 4-8” range with South/East MoCo in the 2-4” range.
