KEY MESSAGES

- Heavy rain continues as a coastal low remains offshore. Widespread 1 to 3 inches is expected with pockets of up to 6 inches possible.

- An approaching cold front will keep precipitation lingering through early Saturday with milder air filtering in through early Sunday

- Dry and cool conditions expected Monday through the midweek as a stronger high pressure airmass moves into the region.

SHORT TERM

(Today through Saturday night) Issued at 528 PM CST Thu Dec 4 2025

Widespread heavy rain continues to impact Acadiana with widespread 1 to 3 inches of rain and pockets of higher amounts. Tonight through Saturday we will continue to see periods of moderate to heavy showers as low pressure remains offshore with weakness aloft. Moisture will remain an issue as PWATs remain near the 90th percentile with low and mid-level RH values above 75%. This will create conditions that will be favorable for efficient rain rates and the possibility for localized flash flooding. As the surface low continues to move eastward, conditions will slowly improve. By the end of the weekend, dry air aloft will put an end to the widespread rain with any remaining convection remaining offshore.

Temperatures will remain chilly despite the overcast skies and rain with lows in the 30s and 40s and highs in the 50s. Overall, the short-term forecast is for wet and cold conditions.

LONG TERM

(Sunday through Thursday) Issued at 528 PM CST Thu Dec 4 2025

The rest of the weekend and into next week looks to be calm due to post-frontal high pressure and strong cold air advection. At the start of the work week, we will be looking at some large temperature swings with highs in the 50s to 60s and lows back down into the 30s and 40s. This cool down will be short-lived as onshore flow will return as surface high pressure builds in the Gulf and pushes warm marine air north. Temperatures will rise in response, with our highs breaking back into the 70s and our lows into the 50s. The end of the week and going into the weekend will be benign as dry air aloft will keep PWATs around half an inch and PoPs will remain near zero.

AVIATION

(00Z TAFS) Issued at 539 PM CST Thu Dec 4 2025

Widespread showers are beginning to lift out to the east with lingering light rain seen near AEX and at LFT, ARA. Conditions should improve overnight with only sparse mentions of light rain mentioned through the morning. Impacts to CIGs and VIS will be driven by low ceilings and fog with sharp moisture trapped at the sfc. No dense fog anticipated.

Another round of light rain will be expected tomorrow with no improvements to CIGs and VIS.
