Well... we are rounding out 2020 with some rain. Today will be the last dry day as we have a cold front set to arrive New Year's Eve and another storm system to our south will bring widespread rain chances just in time for New Year's Day. So with that being said... enjoy the sunshine and drier weather while it's here because wet weather is on our doorstep!
Clouds increase this evening ahead of the cold front that will move in from the Ohio Valley and the Great Lakes region. Here is the set up for New Year's Eve. A cold front will cut through the region in the morning around daybreak and bring light showers to not just the Mid-Atlantic, but for areas up and down the eastern seaboard. With colder air advancing into New England from the northwest, snow showers will linger through the morning hours before tapering off by midday.
Cecil, Harford, Baltimore, Carroll, and Howard counties will see these showers first before the line of rain dips farther south. The metro, Anne Arundel, and northern parts of the Eastern Shore will get in on the rain later in the day. Rainfall totals through New Year's Eve will be insignificant as only a few hundredths of an inch can be expected. Models show rain tapering off just in time for the ball drop!
Don't get too excited just yet... low pressure system #2 will travel northward through the Midwest, allowing a warm front to slide through our area Friday morning. This will bring the first wave of moisture and possibly some ice out towards western Maryland as temperatures start off in the mid-30s. The cold front will follow behind, keeping widespread rain around Maryland through Friday evening. Anywhere from .25-1" of rain can be expected with higher amounts around Southern Maryland and along the Mason Dixon line.
