WEDNESDAY NIGHT NOTES... The new 00Z model set is in, and the basic ideas remain the same for Friday.

*A messy mix of snow, sleet, and some freezing rain will move into the northern half of Alabama during the pre-dawn hours Friday. With temperatures in the 28-32 degree range and a cold infrastructure, bridge icing will begin quickly. Perhaps some ice/snow accumulation on black top roads.

*Main threat of icy travel early Friday is along and north of I-20, but icy patches are possible down to U.S. 80 and I-85 (issues there won't last long)

*With warm air advection during the day, the wintry precipitation will turn to just a cold rain over by late morning Friday with temperatures rising into the mid 30s. This should lead to greatly improved driving conditions.

*The exception is far North Alabama, where sleet or snow could linger into the afternoon and evening hours. Greatest snow accumulation should be over the Tennessee Valley, where a few spots could see 2-4 inches. Amounts will be much lighter to the south.

*A winter storm warning will likely be issued soon (for Friday's storm) for parts of North Alabama, with a winter weather advisory down into the central counties.
