A front has moved through Acadiana, so expect much cooler air through the next few days. Readings could fall into the upper 30s/lower 40s tonight and only rebound into the middle 50s tomorrow afternoon. Readings could be in the mid-upper 30s both Monday and Tuesday mornings.
A warming trend will begin by Wednesday and Thursday ahead of a slow-moving cold front. This front will slowly work through the area in pieces Thursday and Friday, giving us rain chances both days.
Just beyond the seven day forecast, within the next 8-12 days, models are coming into better agreement on the long-term weather pattern across the U.S.
The Arctic air, that has been bottled up across northern parts of Canada, could begin to plunge southward into next weekend and the week after. Models have the cold air coming in in pieces through a week to two week period. It's way too early to know when exactly this cold air will arrive and how cold it will be, but the main takeaway is that winter could return with force for the latter half of January.
