Area Forecast Discussion National Weather Service Lake Charles LA 108 AM CDT Wed Jun 10 2026
New DISCUSSION, AVIATION, MARINE, FIRE WEATHER
KEY MESSAGES
- Typical isolated to widely scattered daytime shower activity can be expected throughout the week as we remain under an upper level ridge.
- Hot and humid conditions will also continue with afternoon apparent temperatures or the heat index between 100 and 105 each day with moderate heat risk.
- The ridge is expected to break down early next week as a front approaches increasing rain chances.
DISCUSSION
(Today through Tuesday)
Issued at 1215 AM CDT Wed Jun 10 2026
Large area of upper high pressure ridging covers the southeast US by a wide margin. Anomalously humid airmass remains in place, and beneath this high, it's very warm, very humid and rather miserable outside. So it goes for the first week of Meteorological Summer!
Little change will be had over the coming days as the pattern is rather stagnant. Some variations to the ridge over the coming days should result in 10 to 20 percent chance of afternoon showers (an isolated thunderstorm cannot be ruled out.) But largely, the next week will be a wash-rinse-and repeat kind of forecast. Each day will see temps in the 90s, and with daily RH values around 60 percent, that heat index will still come into the low 100s to as high as 108F for inland areas (where high temps will squeak into the low to mid 90s).
The longer we go into a heat wave like this, the more the heat stress acts on the body. Maintain good heat safety as much as possible each and every day: hydrate, take frequent breaks, check on those vulnerable groups around you.
As for rain chances, there are some low end PoPs from tomorrow to the end of the week. This is to account for the seabreeze showers which can make their way up and past the ridging. As the high meanders around, there could be pockets of daytime showers/iso storms to pop up later in the day. The summertime normal.

AVIATION
(06Z TAFS)
Issued at 1215 AM CDT Wed Jun 10 2026
Light winds and mostly clear skies expected across the area tonight.
Patchy light fog may bring brief periods of MVFR visibility to AEX/LFT/ARA and perhaps also LCH shortly before sunrise, after which VFR conditions should prevail through the remainder of the period with 7-12 kt southeast winds. Cannot rule out a stray shower or thunderstorm popping up along the seabreeze in the afternoon, but any convection will be very isolated with mid-level ridging overhead, so will leave any mention of showers out of the TAFs for this cycle.

FIRE WEATHER
Issued at 1215 AM CDT Wed Jun 10 2026
Anomalously warm and humid conditions will persist over the coming days with only low to occasionally breezy south winds to offer some reprieve. High pressure settled on top of the northeast Gulf will keep majority of rain chances from the forecast, but afternoon seabreeze showers with an isolated storm or two will be possible near the coastal areas.
