788 FXUS64 KLCH 201948 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 248 PM CDT Mon May 20 2024 ...New SHORT TERM, LONG TERM, MARINE... .SHORT TERM... (Tonight through Wednesday night) Wx map shows weak surface high pressure ridge across the Eastern U.S. with southeast winds continuing over the Northern Gulf of Mexico, Louisiana and Southeast Texas. Visible satellite imagery shows scattered cumulus across our region. Radar shows no precipitation. Afternoon temperatures in the upper 80s to near 90 expected to rise a couple more degrees. For tonight, expect low level increasing cloudiness that is typical for this time of year. Winds expected to stay elevated over the I-10 corridor southward, but likely to fall to 5 mph or calm further north. Due to the cloud cover, slightly higher winds, and the shorter nights, fog becoming less likely. Probably the most expected is patchy fog near daybreak and will quickly dissipate once the sun rises. Lows in the upper 60s to lower 70s. For Tuesday through Wednesday night, the mid to upper level ridge over Northern Mexico/South Texas/Western Gulf of Mexico expected to ridge further east northeastward. This will keep all precipitation well north of the region, with none expected here. Expect above normal temperatures with highs Tuesday and Wednesday in the upper 80s to lower 90s, and lows Wednesday in the lower to mid 70s. 08/DML && .LONG TERM... (Thursday through next Sunday) Above normal temperatures and little if any precipitation is expected through Memorial Day weekend as the mid to upper level ridge presides over the Northern Gulf of Mexico, keeping most of the moisture and lift north of the region. However, humid southeast winds will prevail. Temperatures will remain above normal. Overnight lows expected lower to mid 70s north of I-10, mid to upper 70s further south. Afternoon highs in the lower to mid 90s north of I-10, near 90/lower 90s further south. Maximum heat index values expected to rise to 100-105 degree range over Memorial Day weekend. 08/DML && .AVIATION... (18Z TAFS) VFR expected this afternoon and evening, with southeast winds 8-10 kts. After 06z, MVFR ceilings expected to form at all sites, with intermittent MVFR visibility between 10-13z with the winds briefly becoming calm near daybreak.

Winds and seas are forecast to increase by Tuesday due to the pressure gradient increasing between surface high pressure to the east and low pressure across the Plains.
