It has been a warm start to December as the average high at the Lafayette Airport for December is 74°! But we are finally going to see a strong cold front filter in much cooler air by Monday afternoon. Tracking the front right now it is currently in Texas and stretches northward to the Ohio Valley. Behind the front temps have cooled off by 20° in some areas. Once it passes through Acadiana we will see a big swing like that with lows dropping into the upper 30s by Tuesday morning. Looking further out this may be the last time that we see upper 70s to lower 80s until Spring of next year.
