Patchy to dense fog continues to push to the north across portions of the Coastal Plains this morning based on surface observations and Night-Time Microphysics satellite imagery. Sooner than later, areas along and east of a La Grange to Gonzales to Karnes City line are likely to experience reduced visibilities of a few miles down to 1/2 mile. Can't rule out a few places going down to 1/4 mile briefly. Use low beam headlights and leave extra space between you the vehicle ahead of you. Visibility will improve by 9 AM CST this morning.
