Beautiful Sunday Before Big Changes

Video Forecast

It was a beautiful Saturday across Acadiana as sunshine helped bring some warmth to some pretty cool temperatures. Clear skies will stick around overnight. Moisture begins to return overnight, but that won’t stop temperatures from falling into the upper 30s and low 40s. Areas from I-10 north will see the upper 30s. Sunday will be the definition of perfect fall weather with sunny skies and temperatures right at 70. A nice southerly breeze will keep it from feeling too warm in the afternoon.
Tonight: Calm, clear, and cold. Low: 39°
Sunday: Plentiful sunshine. Mild. High: 70°
Monday: Increasing clouds. Rain showers develop late. High: 71°
A big change is on the way for next week. Monday will see cloud cover increasing through the morning. A southerly wind will bring in higher humidity levels ahead of a powerful cold front. This will set the stage for rain showers to develop later on in the evening. The greatest chance at rain will be after sunset and through the night. The arctic front will move through sometime before midnight and temperatures will plummet through the overnight period. The upper levels will be way too warm for any frozen precip to make its way through Acadiana, but temperatures will reach the mid-to-upper 30s by daybreak. The cold rain will end before Noon, but clouds will hang around throughout the day. A strong northerly wind between 15 and 20 mph, gusting over 30 mph, will create wind chill values in the 20s. We will not get out of the 40s for highs Tuesday. The clouds begin to break up during the evening and temperatures take a tumble overnight into the upper 20s north of I-10 and below freezing south of the interstate. This will be a light freeze for Acadiana as we will briefly be at or below the freezing mark (only for one to three hours) before we warm up. A hard freeze is possible in far northern Evangeline Parish. Beyond this frigid night, the cold remains for Wednesday with highs in the low 50s and clouds build back in as an upper level low moves through the Gulf. This will allow for a few more showers to form up Wednesday night and Thursday morning. With the cloud cover and returning moisture, lows will be in the low-to-mid 40s Wednesday night. The rest of next week looks cloudy and cool as the jetstream sits right on top of Acadiana. Highs will be in the low 60s Thursday through Saturday.
