12/07 Ryan’s “Winter Weather” Thursday Forecast
The time for the most significant chance of winter weather we’ve seen in a while has finally arrived. The scattered showers have continued, and as we cool tonight we’ll see a wintry mix developing on the tail end of this system’s moisture as it moves East out of the area. It’s reached the point where I’m certain that frozen/freezing precipitation will move into South MS, but the rain/snow line seems like it will set up about halfway through the area, so the winter weather conditions will be worse to the Northwest while the Southwest will see mostly rain. Regardless of where the winter weather actually ends up, the conditions will not be conducive to safe travel. Bridges and overpasses are colder than the surrounding roads, and ice may form as early as tonight even though surface temperatures will remain above freezing. My “worst case scenario” for this event right now brings about 2″ of snow to the area right around Hattiesburg, but only a half an inch in the lower counties and accumulation is not expected. The rain/wintry mix will last into the early afternoon, then we’ll see clearing through the night and even colder temperatures for the weekend. Stay tuned for updates.
