Discussion              

Today will start off quiet, but that’ll change pretty dramatically by day’s end with a potent storm on the way. Strong low pressure will push towards the Great Lakes today and then grind to a halt, transfer its energy to a secondary system off the northern Mid-Atlantic coastline.  The end result around here will be occasional rain from later this morning into early Saturday and sleet can mix in at times across some of the N/W suburbs. In addition, the winds will pick up in intensity and the unstable atmosphere can generate a thunderstorm or two in the region tonight as the secondary low intensifies off the coast. High pressure takes control of the weather in the area later this weekend and sticks around early next week. 

Looking ahead, the overall weather pattern across much of the nation will turn colder later next week and beyond due in part to impact from a stratospheric warming event and high-latitude blocking. This colder pattern is quite likely to result in some snow opportunities for the Mid-Atlantic region.
