Warm, moist air will surge northward over the Gulf of Mexico this week keeping our temperatures warm and cloud cover in place. Because our winter has been so cool, the waters just offshore have cooled into the 40s and 50s over the past few weeks. When the warm moist air moves over the colder waters, a marine layer of moisture forms. This marine layer keeps foggy conditions over the Gulf and the coastal areas and low clouds for the inland areas.
This pattern is expected to remain in place this week until a more significant cold front drifts in late Thursday into Friday. Another weaker front will push southward and stall over Acadiana later today and tonight. This will pool some of that Gulf moisture over Acadiana, so fog might be more widespread Tuesday and Wednesday morning.
Afternoon highs are expected to climb into the 70s this week and 60s over the weekend. A few sprinkles are possible today and tonight. A much better chance for rain will come in late Thursday and early Friday with a cold front.
