It’s promising to be stormy evening tonight. A severe thunderstorm watch is in effect for much of Acadiana through 10pm, but I think our greatest threat this evening will be heavy rainfall. Look for localized street flooding especially from Lafayette, Vermilion, St Martin, Iberia and St Mary Parishes tonight. Most areas will see 1-3 inches of rain, but isolated areas of up to 5 inches will be possible, especially in Vermilion, Iberia and St Mary Parishes. Activity will begin to end from west to east during the 200am to 600am time frame. Keep it tuned to KATC for the latest…we’ll be baby-sitting the radar!Â
Tomorrow will bring cooler temperatures with drier conditions. I’m still cautiously optimistic for some limited sunshine tomorrow afternoon. The next weather system will sling clouds back into the area by Saturday afternoon with chilly rains likely Saturday night into Sunday morning. The precipitation should end Sunday evening. Christmas day will start out partly cloudy and cool, but there is still uncertainty with the next upper disturbance that follows Monday evening. There might be some very light precipitation developing Monday evening, but although it will be too warm at the surface, there is a slight chance of non-accumulating wintry precipitation. I wouldn’t get too excited about this as the risk of precipitation will be 20% or less, and I’m really sticking my neck out on this, so blame Perillo if we don’t see anything…but it’s still worthy of mention. We’ll see what future model runs bring. Nothing like blurring the line between “wish-casting†and forecasting but hey it’s Christmas!
