Winds will increase dramatically later today with gusts possible up to 50 mph, skies will be mainly cloudy and snow showers will linger, temperatures have already peaked for the day in the low 30's and will drop into the 20's later today with rapidly lowering wind chill values
Very winds and becoming frigid with brutally cold wind chill values below zero, partly cloudy skies, upper single digits possible for overnight low temperatures
Mostly sunny, very windy, brutal cold with frigid wind chills below zero, near 20 degrees
Partly cloudy, not as windy, very cold, near 20 degrees
The potential exists for a significant snow event late Sunday into Monday…increasing clouds, cold, snow likely late in the day or at night, near 30 degrees
Snow likely, breezy, quite cold, near 20 degrees; brutal cold at night

The big story today will be the increasing winds which could gust to 50 mph by the end of the day and into tonight. The clipper system that affected our weather around here last night will intensify rapidly today on its way to northern New England where more significant snow can fall. This storm intensification will dramatically stiffen the pressure gradient leading to strengthening winds here later today and tonight primarily out of the northwest. Arctic air will plunge into the region by riding in on those strong NW winds and it'll be frigid tonight and Saturday with brutally cold wind chill values.
On Saturday, copious amounts of moisture will head out of the southwestern states and into the central Plains and then continue right towards the Mid-Atlantic region later this weekend. Significant snow is occurring today in the southwest US (e.g., New Mexico) and it’ll move into the region between Kansas and Indiana on Saturday. By Sunday, this moisture will begin streaming into the Mid-Atlantic region and snow is likely break out around here during the afternoon hours. Quite cold air will be in place in the Mid-Atlantic region with anchoring high pressure systems situated to the north and northwest. This storm has the potential to produce several inches of snow in the entire I-95 corridor region from Sunday afternoon into Monday, but that is still a couple days away and – as we experienced earlier this week – a slight shift in the storm track can have significant impact on the outcome. The storm may push just far enough to the north late this weekend to allow for the possibility of mixing in southern sections of the Mid-Atlantic (e.g. DC metro region) and this would have a big impact on potential snow accumulations. No matter what happens with this early week storm, bitter cold air is likely to follow for much of next week.
