The WSI computer model is hinting that a circulation will form just south of the mouth of the River early Friday morning. NHC isn't talking about it, but I think there is some potential for development since 1) surface pressures are low and 2) there is diverging upper winds over the central Gulf. Diverging upper winds promote rising air motion at the surface. IF there is some development by Friday, we could see some unexpected moisture rotate back over south LA/MS possibly reaching as far north as the CBD. There really isn't a threat to us since the fast upper NW flow should take whatever might form farther down into the Gulf away from us. If that did happen, dry air should be drawn down over us making for a mostly dry weekend. Stay tuned!
In the short term, there is a weak upper disturbance heading across Arkansas tonight. It could increase shower chances here for Thursday PM. No real cold air is in sight, but it appears we are seeing a gradual cool down as the sun angle gets lower in the sky.
