Shreveport, LA – The morning air feels damp and heavy across northwest Louisiana as patchy fog drifts along I-20, hinting at a wetter pattern ahead. Skies will turn gray once again as rain showers move into the Shreveport area by late Thursday, signaling an active start to early December.

The National Weather Service in Shreveport calls for showers developing Thursday afternoon, continuing into Friday, with rainfall totals between a quarter and half an inch possible. Drivers should prepare for slower commutes and reduced visibility, especially along major corridors like I-49 and I-20, where pooling water and low fog could make travel tricky.

Temperatures will hover in the mid-50s to near 60°F, keeping conditions mild but damp. The air stays humid through the end of the week, and north winds late Friday will bring a brief cool-down before skies clear into the weekend.

By Saturday, sunshine makes a return, with highs rebounding into the upper 50s, and Sunday looks even warmer — a welcome break before another potential system approaches early next week.

Five-Day Outlook for Shreveport, LA:

  • Thursday: Showers likely, high 49°F.
  • Friday: Chance of showers, high 50°F.
  • Saturday: Partly sunny, high 57°F.
  • Sunday: Mostly sunny, high 60°F.
  • Monday: Mostly clear, high 57°F.
