Discussion

A much different weather picture today as we start the new work week compared to the past few days thanks to high pressure building to our north across southeastern Canada. As a result, an onshore low-level flow of air has formed and this has pushed in much cooler air to the Mid-Atlantic region from the western Atlantic Ocean. A warm front will lift northward through the region by early Wednesday and temperatures could soar at mid-week, but that surge in warmth will be rather short-lived. In fact, early signs for the long Memorial Day weekend are not all that promising with cool, damp conditions possible for at least part of the time.
