The weather pattern change is upon us as Friday was our last warm day seeing a high of 80° F. A cold front is set to move through Southeast Louisiana Saturday morning bringing a real cold snap with it. A reinforcing front will be moving in next week to keep the cold temperatures in place.

Saturday

Scattered showers and maybe a rumble of thunder will move into the area early Saturday morning behind the cold front. Moisture content in the atmosphere is not too impressive with precipitable water values only around 1.2″ to 1.6″. Due to this, along with rain moving through quickly, rain totals in our area will be limited. Model guidance hints at totals between 0.10″ to 0.25″. Some places might even stay mostly dry.

Now comes the tricky part of the forecast: temperatures. It seems likely that the high temperature for Saturday comes shortly after midnight. Temperatures will be in the low-to-mid 60s. Once the front passes and rain moves in, these numbers will begin to drop into the low-to-mid 50s. The temperature gradient will be quite sharp with northern parishes in the upper 40s and mid 50s more south during mid-morning.

Saturday afternoon temperatures.

During the afternoon, temperatures could rebound into the upper 50s and maybe hit 60; however, that is dependent on how fast the front moves through and whether the clouds clear enough. Cloud cover looks to begin to clear later afternoon into the evening. Winds will be breezy throughout the day from the north around 10 to 15 mph.

Sunday

Sunday morning will be rather chilly as the cold air mass continues to move southward. Low temperatures in the morning will be in the mid-to-upper 30s with near freezing temperatures possible north of the I-10/I-12 corridor into Mississippi. Frost is a possibility throughout the area. Winds will continue to be breezy around 5 to 10 mph. This will bring wind chill into play feeling a lot colder for the first half of the day.

Going through the rest of the day, clouds will be gone as well as humidity. Dew points will fall into the 30s allowing for really nice fall-like weather. Temperatures will struggle to warm up in the afternoon. Highs will be in the 50s. Sunshine during the day might get a few places closer 60° F.

Next Week

Looking ahead, the next system comes through Monday into Tuesday bringing a better chance for scattered showers and storms. Higher rain totals seem likely too with this front. Cold temperatures will continue through the week staying below average.
