[12Z GFS forecast map for Monday morning (blues=snow; purple=ice); map courtesy "tropicaltidbits.com"]
The last in a series of three “clipper” systems produced snow showers in much of the I-95 corridor this morning and there can be residual scattered snow showers this afternoon along with gusty winds. Temperatures will plunge tonight to bitter cold levels into the single digits in many locations and high temperatures on Saturday will again struggle to escape the teens. After another bitter cold night, Sunday will feature an increase in clouds as temperatures modify somewhat to more "normal" cold for this time of year. The increase in clouds on Sunday will be associated with an area of moisture in the south-central US that will head into our direction. This is a different pattern than the recent “clipper” systems which dropped southeastward from the Northern Plains and Upper Midwest into our region. It appears that it’ll likely be cold enough for a wintry mix to occur in much of the I-95 corridor by Monday morning. This wintry mix can certainly include freezing rain and/or sleet just in time to mess up the Monday morning commute. Stay tuned.
