Discussion              

The passage of a secondary cold frontal system last evening ushered in the coldest air mass in a few years for the Mid-Atlantic region and Northeast US.  Despite some sunshine today, temperatures will be confined to the 20’s for highs – way below-normal for this time of year – and a stiff breeze will produce wind chills down in the single digits.  After another very cold night, temperatures will modify some on Wednesday and even more on Thursday with highs likely reaching 40+ degrees on Thursday afternoon. An “ocean” storm will form late this week in the southwestern part of the Atlantic Ocean and it will likely stay far enough off the coast to have little or no impact around here.  The overall weather pattern will, however, likely produce other storm threats for us beginning later this weekend and lasting into at least the middle part of next week.
