BLOG: Cool Then Mild…Again
Back at the start of this week, we identified Friday as one of those “cooler, but not necessarily COLDER” days behind this front. And, even though we should see a fair amount of sunshine, wind gusts could be as high as 30 miles per hour, which should start to relax Friday evening.
The sky cover forecast for this weekend will be giving us some headaches. It appears (from all of the modeling) that there’ll be whole lot of moisture in the mid-levels of the atmosphere that will be spreading southeastward out of the Great Lakes region and southeastern Canada. But there is also another area of clouds that must be watched closely — and this one will be associated with a wave of low pressure emerging in the Southeast! That southern-most feature is destined to move across the Carolinas before it heads out to sea early Saturday morning. And, even though the actual precipitation associated with it will probably extend no farther north than central Virginia, there probably will be a veil of high clouds associated with it that will engulf much of the rest of the mid-Atlantic states. For sake of argument, Saturday’s forecast will mention “times of clouds and sunshine.” We can see how the day starts out rather cloudy, and it ends that way, too — because the clouds associated with the southern feature are present very early in the morning, and then other clouds approach from the north and the west Saturday afternoon and evening. There’s even a slight chance that enough moisture will be getting lifted by an impulse of upper-level energy Saturday night to bring a flurry or snow shower to some places, especially north of the Mason-Dixon Line.
Sunday should be the coldest day of the next five — most temperatures will fail to get out of the lower 40s in the afternoon.
