A very strong cold front is going to bring another round of arctic air as well as potential for some wintry precipitation tomorrow into Friday.
Cold air advection, a passing shortwave (mid/upper level disturbance), and overrunning is likely to lead to a mix of wintry precipitation types from the western Gulf Coast/parts of south Texas to south/central Alabama.
Timing will be tomorrow morning into Friday morning for the Texas Gulf Coast and south Texas. There could also be some light accumulations with generally less than 0.1″ of ice possible.
A winter storm watch has been issued for parts of Texas.
Farther east, across south/central Louisiana into south/central Alabama, the timeframe for potential wintry precipitation looks to be tomorrow afternoon into Friday morning. At this time a layer of warm air aloft looks to keep any frozen precipitation primarily in the form of sleet and/or freezing rain.
Some light accumulations will be possible, mainly away from the coast, but temperatures will warm with daytime heating during the day Friday causing any accumulations to melt. Any impacts from this event should be limited.
