Foggy Start, Rains Return Tonight

Posted: Updated:

A dense fog advisory is in effect for much of Acadiana along and south of Interstate 10. Many areas are reporting visibility dropping below 1/2 mile, even some areas dropping to near zero visibility. Fog will remain in place as a very warm, moist flow off of the Gulf of Mexico stays in place. As low pressure develops to our west, winds should be able to increase and clear out the for over land by mid morning, offshore locations may not see the fog dissipating until early afternoon. 

Temperatures are already at or above our normal highs this morning. Much of Acadiana is sitting in the mid 60s with dew points in the same range. As the fog mixes out, we'll see cloudy skies, but afternoon temperatures should be able to climb well into the 70s, with a few locations getting close to 80 degrees if there are peeks of sunshine. The low developing over the Rio Grand Valley is  expected to track toward Dallas, then toward the Arklatex, and a general eastward movement toward the Carolinas Wednesday. As the low spins northeast, it will be pulling a cold front along with it. This front should clear our area during the overnight period. So just a few showers are expected today, with rain chances increasing during the overnight hours. A line of rain and storms will push through with up to 3/4 inch of rain falling before Wednesday morning. Skies will gradually clear Wednesday, but temperatures will remain warm with highs in the mid to upper 70s. 


Wednesday night into Thursday looks a bit drier, so overnight temperatures should dip back into the mid 50s. It remains warm Thursday into Friday with partly to mostly cloudy skies and temperatures in the upper 70s to near 80 degrees. Another front will get in here Friday night bringing the rain chances back through Saturday. Christmas Eve still looks somewhat unsettled with scattered showers and temperatures in the 50s. Colder weather is expected for Christmas Day and much of next week.
