High pressure will be building in and hanging on for most of the week. Temperatures will be considerably cooler today with afternoon highs in the mid 60s. With a tight pressure gradient between a ridge of high pressure sinking in from the plains, and low pressure along a stationary front over the Gulf of Mexico, winds will gust in the 15-20 mph range most of the day. Winds will relax overnight and lows will drop into the lower 40s under clear skies.
Tuesday and Wednesday look to be mostly sunny with highs in the 50s and lows in the 30s. Some patchy frost will be possible, and a few locations over central Louisiana may drop to the freezing point. Both Wednesday and Thursday morning.
Temperatures will moderate by Thursday as highs will climb back into the mid to upper 60s, which is normal for this time of year. By Friday a deep trough will dig across the western half of the U.S. This will also help to spin up a low pressure area along the Texas Gulf Coast. By Friday night, rains will be picking up. Widespread rains are expected Friday night into Saturday. Some rains may be heavy, especially over the southern sections. There will be a significant amount of colder air north of our region, so this system may bring winter precipitation to some of our neighboring states of Texas and Arkansas. Chilly weather will return again to Acadiana by Sunday and Monday of next week.
