High pressure will be over the Capital Region to close out the work week. Fair weather, unseasonably cold temperatures, and a general decrease to the windy conditions experienced yesterday, will be the rule.
The high pressure area will slide off the coast tonight. This will allow slightly milder air to move into the region Saturday in advance of another fast moving low pressure system that approaches the region late in the day. Some snow showers and squalls will accompany this system’s passage during the late afternoon and evening hours Saturday, though moisture looks to be limited, thus accumulations should be held down.
The frontal system stalls to the south of our region on Sunday as low pressure develops over the lower Mississippi Valley and moves east northeast to be over the lower Ohio Valley and mid Atlantic by Sunday evening. The Capital Region will be on the northern extent of a large precipitation shield associated with this system as it drives warmer, more moist air from the Gulf of Mexico and Atlantic Ocean along the stalled out boundary, and wrings out that moisture to the north of the boundary. Some snowfall is anticipated on Sunday evening through the day on Monday before the system quickly pulls away from the region Monday night. A return to fair weather, with a gradual moderation in temperatures, looks to be in store by the end of next week.
