A cold front will sweep through today, with a weak area of high pressure preparing to build in behind it tomorrow. The front will bring an end to a stretch of clear and sunny conditions, with overhead clouds thickening and eventually lowering to the ground as fog today. This afternoon, in advance of the front, a few snow showers may fire, but the weak nature of the front suggests no significant accumulations should be expected. The front will clear the region tonight, leaving behind intermittent fog for the remainder of the overnight hours. Behind the front tomorrow, the flow will shift towards the southwest under the influence of a weak ridge of high pressure, ushering moist and even milder air northward. This will instigate a warming trend over several days that will commence tomorrow, with afternoon high temperatures approaching the freezing mark.
