A wave of low pressure is sliding across the eastern Great Lakes and into southeastern Canada. This body of low pressure will be dragging a warm front eastward Friday, and surface winds will be shifting to the southwest. This should allow for the some low clouds, as well as patchy fog early Friday to break for some sun during midday and the afternoon.
We are noticing some convective activity occurring very early Friday morning, which is causing showers and a few embedded thunderstorms across northeastern Pennsylvania and in upstate New York. Most of those showers and thunderstorms will slowly weaken as they move right into the teeth of some much cooler and more stable air. But as clouds and fog do break for sunshine Friday, and some of the much warmer air starts getting pulled to the east, the
temperature should have no trouble climbing into the lower and middle 80s, except along the Eastern Shore and near the Bay.
We think that the rainfall totals across the Greater Baltimore Area during the next 24 hours will average a general 0.10″ to 0.25″, although there may be some pockets of heavier rain that may bring closer to an inch in spots before all is said and done. As this cool front manages to press southward across the region late Friday night and Saturday morning, winds will be shifting once again and will become more northeasterly. With that, there will be some clouds around
Saturday, and perhaps even a leftover shower, especially during the morning. But the bottom line is that there will be some sunshine, especially from midday on. Most temperatures will be still be able to reach the lower 80s Saturday afternoon.
