Finally it appears that Acadiana will see it’s first “real” taste of fall starting tonight! As of early this morning the front was located along the Arkansas/Louisiana line heading southeast. The bulk of the cold air will still be pushing farther to the east, but the lowest temperatures since mid May might be here early Wednesday morning!
The upper 3/4 of the atmosphere is very dry, which is why we’re seeing clear skies this morning. All of the moisture is confined to the bottom, (where we stand) and the humidity is still pretty high. Temperatures will climb to the lower 90s today ahead of the front with the heat index approaching 100. There may be one or two pop up storms along the front, but the most of the air is starved for moisture, so I’ll run with 20% on the rain chance as the front moves through. But by late this afternoon, you will feel the north breeze and the drier air moving in. By the early evening most of Acadiana will be feeling it too as the front moves offshore. Under clear skies tonight, lows will hit the mid 60s!
Tuesday will be sunny and pleasant! Highs will be running a couple of degrees below normal. Normal high for Tuesday is 86, normal low is 65. We’ll run in the low 80s with low humidity. Tuesday night into Wednesday morning lows across the majority of the region will fall into the 50s. 60s will linger along the coastline. Wednesday will be sunny and pleasant again.
By Thursday, humidity will return again ahead of the next front, and by Friday with the front moving in, showers and thunderstorms should return. Saturday and Sunday’s forecast is a little more difficult to predict this morning. Some model solutions push the front through clearing things out over the weekend, other stall the front along the coast keeping some rain chances for Saturday and Sunday. Right now I’ll swing toward the “Going Through” solution based on 40% confidence/60% wishful. The weekend is still four days away. Hopefully the picture will become more clear in the near future.
