Brian's exclusive forecast for Annapolis: Areas of morning fog giving way to a mostly sunny afternoon. Warm with a high in the mid to upper 80s. Winds light and variable. Tonight, mostly clear and warm with a low around 70. Warm and humid on Saturday with a slight chance of an afternoon thunderstorm. A high of 88 degrees is expected. The outlook for Sunday and Monday calls for warm and humid conditions with scattered afternoon thunderstorms and a high of 88 degrees each day.
High pressure near the Great Lakes region will move southeast and build over Chesapeake Bay later this afternoon. Until then, areas of fog around the bay this morning will give way to a mostly sunny afternoon. At 8 a.m., temperatures around the bay are in the low 70s and calm winds. The mercury will rise into the 80s this afternoon under a mostly sunny sky. As we move into the weekend, warmer and more humid conditions will develop as a clockwise flow around high pressure brings a southerly flow of air to the region. This will also increase the likelihood of afternoon thunderstorms, although storms are not expected to be widespread. Highs on Saturday through Monday should reach the upper 80s. The outlook for early next week indicates that a strong cold front will usher in much cooler and drier air for Tuesday and Wednesday with overnight lows in the 50s and highs in the 70s.
