Friday through Monday. A northwest flow aloft will continue with a couple of vorticity maximums to note. The first to arrive early friday with a very slight chance of snow showers. This one will produce a cyclone and rapidly deepen it over the eastern US which will produce a strong pressure gradient over the area on saturday. 850 mb temperatures will plummet to around -28 C at 18Z Saturday and remain there with only a slight moderation into Sunday. Temperatures on Saturday could struggle to reach 5 with bitterly cold wind chills. Highs Sunday will be around 10 with lighter winds. Temperatures will moderate some what by Monday with highs in the 20s.
