Get ready for a blast of Winter to start the work week after spring-like temperatures on Sunday. A slow-moving cold front finally moves south into the Gulf by Monday morning. Behind the front, a major temperature drop comes along with it as temperatures will be as much as 30 degrees colder than the high of 79 on Sunday afternoon.
Expect temperatures to fall into the upper 40's. Highs may climb a degree or two to the 50 degree mark early, but fall late in the day with the official lows coming just before midnight, Monday. Moist air riding over the cold air at the surface will allow for a cold drizzle for most of the day making it very uncomfortable to start the week. Temperatures to the north and west drop to the freezing point overnight into Tuesday morning creating an opportunity for some light freezing rain near the Mississippi state line and to the north and west of Baton Rouge. It will also be very breezy behind the front.
The cold, wet weather holds on into the middle of the week. A reinforcing shot of cold air moves in Wednesday. That air will dry us out for the end of the week. Thursday through Saturday will be much drier. Temperatures slowly warm towards the weekend as well. The active weather pattern also leads to rocky seas off shore. Small craft advisories are in place and likely to continue.
