Discussion

The stubborn “closed” upper low that has been impacting our weather since the weekend will finally slide to the northeast today as it “opens up” enough aloft to get captured by the polar jet. As a result, our weather will improve today featuring plenty of sunshine with comfortably warm conditions. A cold front will then drop slowly southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region by late in the day. At the same time, a new upper-level low will develop over the Mid-Atlantic region and surface low pressure is likely to form along the cold frontal boundary zone. The end result should be more showers and thunderstorms around here from later tomorrow into Friday and perhaps even a period of steadier rain. The weekend and early part of next week are shaping up quite nicely with increasing amounts of sunshine expected on Saturday and mostly sunny skies on Sunday and Monday. Beyond that, another unsettled period develops in the Mid-Atlantic region by later Tuesday and Wednesday of next week with a Gulf system likely to ride up along the Atlantic seaboard.
