We'll get to the snow potential in a moment, but first to consider our current weather as the pattern continues for at least one more day with fog through the morning then redeveloping after sunset. After the fog temperatures, it will warm quickly with afternoon highs a degree or two warmer than Saturday. With more afternoon sunshine fog formation will be more limited overnight tonight and into Monday morning due to the drier ground conditions; however, some patchy fog is still possible across the area and there could be yet another Dense Fog Advisory for parts of the area early Monday morning. Also, don't forget tonight is the night for the Full-Supermoon so check it out early before the fog forms. The dry conditions continue Monday but the ridge of high pressure responsible for this weekend's dry weather will shift east ahead of a developing storm system. Temperatures will still be well above average Monday afternoon ranging from 69 to 73 degrees. A major change in the weather is expected beginning Tuesday as a deep area of low pressure develops over the Eastern U.S. with an accompanying cold front approaching, bringing increasing rain chances from northwest to southeast through the day as the front moves across the region.
There could be enough instability for a few embedded thunderstorms and although no widespread severe weather is expected near the front in North Alabama, there could be some strong wind gusts. This weather setup; however, will likely not be conducive to tornadic development. With ample moisture in place; however, this system will produce higher rainfall totals than the systems which we've experienced in the past month. Rainfall amounts could exceed one inch in some locations. Much colder and drier conditions are expected as the area of low pressure stalls over the Eastern U.S. and with several disturbances rotating around the trough, reinforcing shots of cold air will bring even colder temperatures by week's end and through next weekend. There could be enough moisture with a fast moving clipper system Friday afternoon and evening for a few rain or snow showers as very cold temperatures in the upper atmosphere move across the Southeast. Afternoon highs Friday and Saturday will range from 46 too 49 with overnight lows in the 24 to 30 degree range
