Southwest Louisiana Weather Outlook: Dry Conditions And Gradual Warmup To Peak Thursday

By Calcasieu Staff
Published December 08, 2025

Lake Charles, Louisiana – Residents in Southeast Texas and in central and Southwest Louisiana can expect a stretch of dry, quiet weather from Monday, Dec. 8, through Friday, Dec. 12, with sunny days, cool nights, and a steady warming trend after Tuesday that peaks late in the workweek.

Forecast data for the five-day period show no rain expected, with a zero percent chance of precipitation each day and night through Thursday night, and continuing dry conditions into Friday. Skies are expected to be sunny or mostly sunny, allowing temperatures to gradually climb after a cool start to the week.


Monday: Cool Day, Chilly Night

Daytime (Today, Monday)

  • High: 59°F
  • Low (daytime forecast): 53°F
  • Rain chance: 0%
  • Wind: North at 10 to 15 mph

A north wind is keeping conditions cooler and drier to start the period. Afternoon highs near the upper 50s will feel seasonably cool for early December, especially with a moderate northerly breeze.

Monday Night

  • Lows: 32°F to 36°F
  • Rain chance: 0%

Under clear skies and dry air, temperatures will drop quickly after sunset. Lows in the lower to mid-30s mean a light freeze is possible in some inland locations. Sensitive plants and outdoor pets may need extra protection overnight.


Tuesday: Cool To Mild, Light Winds

Daytime Tuesday

  • Highs: 58°F to 62°F
  • Rain chance: 0%
  • Wind: Light and variable

With light and variable winds and continued dry air, Tuesday remains on the cool side but begins a slow warming trend. Sunshine will help afternoon temperatures climb into the upper 50s to lower 60s, which will feel slightly milder than Monday.

Tuesday Night

  • Lows: 39°F to 45°F
  • Rain chance: 0%

Overnight temperatures moderate compared with Monday night, staying mostly in the upper 30s to mid-40s. The risk of freezing temperatures decreases as the air mass begins to warm.


Wednesday: Noticeable Warmup Begins

Daytime Wednesday

  • Highs: 69°F to 73°F
  • Rain chance: 0%
  • Wind: Southwest at 5 to 10 mph

A shift in the wind to the southwest brings in warmer air. Highs jump into the upper 60s to lower 70s, marking a clear transition from cool to pleasantly mild conditions. Sunshine and a light southwest breeze will make the day feel comfortable, especially during the afternoon.

Wednesday Night

  • Lows: 45°F to 52°F
  • Rain chance: 0%

Nighttime temperatures continue to trend warmer, with lows mostly in the mid-40s to low 50s. This is a significant change from the near-freezing readings expected Monday night.


Thursday: Warmest Day Of The Week

Daytime Thursday

  • Highs: 71°F to 76°F
  • Rain chance: 0%
  • Wind: South at 5 to 10 mph

Thursday is forecast to be the warmest day of the period. A light southerly wind, combined with dry air and sunshine, will push highs into the lower to mid-70s. For early December, these temperatures are relatively warm, offering a brief taste of springlike weather without the humidity or stormy conditions that often come with it in other seasons.

Thursday Night

  • Lows: 47°F to 54°F
  • Rain chance: 0%

Overnight lows remain mild, generally in the upper 40s to mid-50s, as the air mass stays warmer and moisture levels slowly increase, though not enough to produce rain.


Friday: Slight Cooling, Still Dry

Daytime Friday

  • Highs: 67°F to 73°F
  • Rain chance: 0%
  • Wind: Variable at 5 to 10 mph

A slight dip in temperatures is expected Friday, though conditions remain very comfortable for December. Highs in the upper 60s to lower 70s, light winds, and continued dry weather will keep outdoor plans on track. Winds will be variable, meaning they may shift direction but stay light overall.


Overall Pattern: Stable, Sunny, And Dry

Across Southeast Texas and central and southwest Louisiana, the pattern through Friday is:

  • Dry: No measurable rain is expected, with a zero percent chance of precipitation listed for every day and night in the forecast period.
  • Sunny: Clear to mostly clear skies will dominate, allowing for strong daytime warming and quick nighttime cooling, especially early in the week.
  • Warming Trend:
  • Coolest daytime conditions: Monday and Tuesday, with highs mainly in the upper 50s to low 60s.
  • Warmest daytime conditions: Thursday, with highs climbing into the low to mid-70s.
  • Nighttime lows: Near freezing Monday night, then gradually warming into the upper 40s to mid-50s by Thursday night.

This type of stable pattern is typical when high pressure, an area of sinking, dry air, settles over the region. High pressure tends to block storm systems, reduce cloud cover, and keep conditions calm. While this means a lack of rain, it also offers several days of favorable weather for travel, construction, and outdoor events.


Practical Takeaways For The Week

  • Monday Night Freeze Potential: Prepare for lows in the lower to mid-30s, especially away from the immediate coast. Protect sensitive plants and check on outdoor pets and livestock.
  • No Rain Delays Expected: With a zero percent chance of precipitation through Thursday night and continuing dry conditions Friday, outdoor work and activities should not face weather-related disruptions.
  • Layering Recommended: Cool mornings and evenings early in the week will contrast with mild to warm afternoons by midweek and Thursday, so dressing in layers will help adjust to changing temperatures throughout the day.

The region enters this stretch of weather with a rare combination for early December: several days of sunshine, no rain in the forecast, and a gradual warmup that peaks comfortably rather than excessively.
