Sunday Afternoon Forecast Discussion – 2 p.m.
October 7, 2012 Leave a comment
The cold front has pushed through all of Central Alabama. In its wake colder and drier air is filtering into the state. Post frontal stratus clouds are beginning to mix out across the southern portion of the area, but not so much across the northern half of Central Alabama. This is most likely due to more mid to high level clouds in place across northern Alabama. High temp forecast today is tricky and will be based on how much the low clouds mix out. Thinking is that areas in the southeast Montgomery and Troy will see the warmest temps given the low clouds already breaking up. Areas farther north Tuscaloosa, Birmingham, Anniston and Talladega will be on the edge of the mostly clear/mostly cloudy line.
An upstream shortwave trough now in Colorado and New Mexico will dig into the Southeast overnight. Even with relatively dry surface dew points the 12z KBMX sounding and most models suggest there will be enough moisture and lift above the dry/stable boundary layer to support light precipitation and increasing clouds from the west after midnight. Therefore there is a slight chance and chance of showers in place for late overnight period for areas generally along and north of I-20. But we can expect a beautiful week ahead with lots of sunshine and nice mild temperatures.
