Dense fog will slowly burn off through the morning, but visibility will likely remain below a mile in many locations through at least mid morning. The fog is certainly an indication of [...]

The upper low and coastal low that brought have rainfall to the forecast area overnight is beginning to weaken and lift to the north and east. With significantly moist air trapped below 850 MB, a cloudy day can be expected. [...]

Get ready to say good bye to the ridge in the East or at least the sustained ridge in the East.

The upper level pattern will shift to a predominant trough into the eastern United States. A strong cold front will move [...]
