After a warm start to December with highs in the 70s to 80 degrees, big changes are in store for Acadiana through this weekend.
Cloudy, breezy and colder weather is anticipated Friday through Monday with occasional periods of chilly rain likely.
Temperatures should stay above the freezing mark in Acadiana while we have the best precipitation chances, but some activity Saturday morning and then again Saturday night through Sunday morning, could mix with some sleet.
No accumulations are expected locally as ground temperatures remain above freezing.
The greatest threat of sleet and perhaps freezing rain will be confined to the central and northern part of the Bayou State this weekend.
It will stay very grey with plenty of clouds through Monday night...so once the coldest air arrives it will likely stay locked into the region...and last through much of next week (although we should see some sun by Wednesday).
Look for highs Friday in the 50s early in the day, but dropping into the 40s Friday evening and eventually in the mid-30s Saturday morning. Scattered showers will eventually decrease to patchy light rain/drizzle late Friday night ending briefly Saturday morning.
Temperatures Saturday will be very cold with highs likely in the upper 30s to near 40 under cloudy skies.
Another disturbance will engender more rain Saturday night, with some activity possibly starting out as sleet. Temperatures will moderate Saturday night into Sunday staying mostly in the 40s.
Sunday will likely be wet, especially in the morning, with yet another disturbance riding in the sub-tropical jet stream to bring more chilly rains Monday.
Latest computer model guidance clears us out for mid-week with the chance of light freezes a good bet for Tuesday, Wednesday and perhaps Thursday mornings...we'll see as this type of pattern leads to a very changeable forecast, so stay tuned!
