Areas of morning fog will be our primary weather concern over the next couple of days. Warm, moist air moving inland from the Gulf of Mexico over somewhat cooler land areas will result in areas of what we call sea (or advection) fog. The National Weather Service in Lake Charles has already posted a Dense Fog Advisory for parts of south-central and SW Louisiana.
So it’s back to the 70°s for the next couple of days, but Mother Nature has thrown us a curve ball over the last 12-24 hours, changing up the forecast for Friday and through the weekend.
We still expect a front to ease its way over south Louisiana by the latter half of the day Friday and into early Saturday morning. What has changed is that now it’s looking like it will be a “mainly dry” boundary, producing little, if any, measurable rainfall over the WAFB viewing area. The front looks like it will essentially stall along or near the Louisiana coast, then either fizzle out or drift northward as a weak warm front Saturday into Sunday.
The main point is that we stay mainly dry and the temperature drop we anticipated for the weekend will be much smaller than what we’ve been forecasting for the last couple of days. If you remember, while our prior weekend forecast was dry, we were calling for highs in the 50°s on Saturday and around 60° or so for Sunday. Now, we’re thinking that we’ll keep a very slight chance of rain in the Saturday morning forecast, with partly cloudy skies for Saturday afternoon and Sunday. In addition, look for highs in the 60°s for Saturday and up near 70° for Sunday -- great news for area parades!
Yes, it’s kick-off time for BR’s Mardi Gras Parades! The ‘Red Stick’ parade season starts with the Krewe of Jupiter & Juno on Saturday evening (6:30-9:00pm) along its downtown route. Then on Sunday at 10:30am, North Boulevard goes to the dogs, with the Mystic Krewe of Mutts festivities.
Heading into next week, it’s more daytime highs in the 70°s for Monday, Tuesday and Wednesday. With a southerly flow in place, we’ll put very low rain chances in the forecast for Monday (10-20%) and Tuesday (20-30%). The extended guidance timing still needs some tweaking, but for now we anticipate a more potent cold front to arrive Wednesday, with rain likely then.
