The NWS has issued a Dense fog Advisory for Barrow, Jackson, and Walton counties for visibilities less than 1/4 mile. This area of fog is moving westward and will most likely include Gwinnett county, as it's already very foggy here at DaculaWeather.com as you can see from our webcam.
A very intense low pressure system will form over Florida and move up the east coast this weekend bringing very windy, perhaps gale force winds to parts of the mid Atlantic. Heavy snow will fall in the mountains of TN and NC and further up into VA and points north. This will be a major spring storm for many parts of the northeast. The pressure gradient will be very strong as the low pressure moves up the coast creating very windy conditions for us on Sunday and will most likely be high enough to have Wind Advisories issued for most of north and central Georgia.
Temps will be cooling down again with highs in the 60s and lows in the 30s for Monday and Tuesday and we won't see the 70s again until Wednesday.
