Watch on posterous
Continuing wtih Mike’s forecast: Cold Canadian air will interact with an upper level storm system pushing through Texas and into the Lower Mississippi Valley and Deep South, bringing a chance of wet snow across much of the Lone Star State eastward into northern and central Louisiana today and tonight. A brief period of light snow or sleet will also be possible further to the east across Mississippi, Alabama and Georgia on Wednesday morning before the precipitation shifts to the north and east.
Accumulations of snow are forecast to average from 1 to 3 inches across much of Texas with isolated higher amounts up to 4 to 6 inches possible in a swath extending from the Midland/Odessa area eastward through San Angelo, Waco, Killeen and Temple. To the north, the Dallas-Fort Worth area could receive as much as 2 to 4 inches, especially on the south side of the Metroplex.
Across south-central and southeast Texas, rain showers will mix with and eventually change over to sleet and snow from west to east through the day. Accumulations will range from 1 to 3 inches in Austin with a trace to an inch possible in both San Antonio and Houston. By tonight, accumulations of 1 to 3 inches will push as far east as Shreveport and Alexandria, Louisiana.

Snow will come to an end from west to east through the evening hours today and early morning hours on Wednesday. However, many locations will see morning low temperatures tomorrow fall to near and below freezing. This may result in slick and hazardous conditions on roadways, especially on bridges and overpasses.
