.DISCUSSION...

A much colder air mass will continue to move south today through
most of the upcoming week, with strong and gusty northerly winds
to continue. A surface low is expected to develop across the
Western Gulf of Mexico along the front today, and move east
tonight into Tuesday, allowing for stronger winds in that time
frame. This surface low will also generate widespread winter
precipitation, with 4 to 6+ inches of snow expected Tuesday along
the U.S. 190 and I-10 corridors of Louisiana and Southeast Texas.
A mixture of sleet and snow will be likely across the coastal
parishes and counties Tuesday. Hard freeze conditions are expected
Tuesday through Thursday mornings, with Wednesday morning lows
reaching 10 to 15 degrees across the area.
