897 FXUS64 KLCH 010508 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 1208 AM CDT Mon Jun 1 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Humid and muggy weather will continue through the start of the work week. Temperatures will warm by a degree or so each day thru Tuesday. - Precipitation chances will increase marginally over the week. A frontal boundary will arrive mid this week. - Heat Indices in the upper 90s to lower 100s can be expected thru Tuesday. Practice heat safety! Hydrate, take breaks, and stick to the shade. && .DISCUSSION... (Today through Sunday) Issued at 1204 AM CDT Mon Jun 1 2026 Current conditions still remain plenty warm and humid, with temps in the mid to upper 70s and near matching dewpoints. At the surface, the high pressure will maintain light southerly to near calm flow. Tonight, we could see another round of patchy fog. While dense fog is not expected, it is advised to commute with caution late tonight into early tomorrow morning. Other than being careful with the potential fog, it is definitely advised to be cautious while outdoors today and tomorrow. Highs will get into the upper 80s to mid 90s with dewpoints in the 70s. This will yield heat indices in the 100s in some areas. While the issuance of heat products will be unlikely, the probability of feeling like a melted ice cream will be high if one decides to go on a run these next few afternoons. From the midweek period to the end of this forecast period, isolated to numerous rain chances will prevail. Some of this activity is expected to be seabreeze / diurnally driven, however it will have some assistance first from a weak frontal boundary (Wed/Thu) then from an upper low expected this weekend. The good news is that the expected rain and cloud cover from mid week are likely to keep MaxTs in check, although one will still be precipitating while participating in outdoor activities. && .AVIATION... (06Z TAFS) Issued at 1204 AM CDT Mon Jun 1 2026 Winds speeds have become near calm tonight under mostly clear upper decks. Thanks to the high moisture content, we could see some patchy ground fog again tonight, however dense fog is not expected at this time. Tomorrow afternoon, we could see some isolated to scattered showers at or in the vicinity of the southern terminals. && .MARINE... Issued at 1204 AM CDT Mon Jun 1 2026 Ridging will remain over Gulf waters to bring about light to occasionally moderate onshore winds, low seas and nearshore diurnal showers. Towards the midweek, upper low pressure will place a weak boundary near the north Gulf coastline, increasing rain chances and seas on increasing pressure gradient. Winds will turn to the east and seas increase late in the work week in response to this boundary and to high pressure developing over the southeast US. && .FIRE WEATHER... Issued at 1204 AM CDT Mon Jun 1 2026 While there remains an anomalously moist airmass also set into the north Gulf, dry conditions from high pressure are allowing daytime RH values to mix down to the 45 to 60 percent range. A slight weakness in the high pressure will develop, allowing for a weak boundary to move into the region. This boundary will then become the focus for more diurnally driven, seabreeze, rain chances to return to the forecast. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None. TX...None.
