Discussion
After high pressure takes control of our weather today, low pressure will intensify near the Carolina coastline late tonight and on Thursday. The pressure gradient between the high pressure system and the intensifying Carolina storm on Thursday will tighten significantly and winds will become quite noticeable around here. The increasingly strong NW winds will usher in a very cold air mass for the end of the week and it’ll stick around for much of the weekend as well. High temperatures on Friday will be confined to the 20's and overnight lows on Thursday night, Friday night and perhaps even Saturday night will be in the teens. Another storm system will cross the country this weekend and threaten the Mid-Atlantic region with snow or a snow/rain combination in the late Sunday/Monday/early Tuesday time frame. This scenario could feature an initial wave of low pressure headed to the Ohio Valley and then the formation of a secondary storm off the Mid-Atlantic coastline.
