FXUS64 KLCH 070609 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 109 AM CDT Thu May 7 2026 ...New DISCUSSION, AVIATION, MARINE, FIRE WEATHER... .KEY MESSAGES... - Rain chances remain in place during the weekend with upper disturbances traversing the region. - Heavy rain and flash flooding will again be possible Friday and Saturday. && .DISCUSSION... (Today through Wednesday) Issued at 1252 AM CDT Thu May 7 2026 As of 0100CDT, widely isolated showers are still present on radar, however they will continue to taper over the rest of the overnight period. In some areas, we could see patchy to dense fog which will mainly be dependent on wind speeds. The front is bisecting the CWA, and will continue its southern progression into the coastal waters where it will stall before weakly retrograding back through our southern zones late today into early Friday. Along with that, we can look forward to yet another round of rain as a cutoff upper low over Baja Cali makes an eastward trek Friday and into the weekend. The swimming pool of abundant moisture and incoming system (especially taking into account the rain we have already received) has prompted WPC to place the CWA in a Slight Risk (lvl 2/4) for excessive rainfall on Friday then Marginal Risk (lvl 1/4) on Saturday. The upper low will weaken and open up to the broader flow late Friday into Saturday, with scattered to numerous showers and storms remaining in the area. Probabilistic rainfall totals for those two days are in the 1 to 3 inch range with 10 percent exceedance values upwards of 4.5 inches across a portion of the eastern half of the CWA. Isolated to scattered showers will linger into Sunday, however it will all be pushed out by another cold front that will progress through mid to late Sunday. A surface high pressure will move in Monday, with the conditions it will bring being short lived as the high moves off to the east of us on Tuesday, with southerly flow returning from then and into the middle of next week. For most of the forecast period, temperatures will be kept in check by overcast skies and rain, along with the front. They will be generally within 3 to 8 degrees from climatological averages for this time of month. && .AVIATION... (06Z TAFS) Issued at 1252 AM CDT Thu May 7 2026 Widespread IFR conditions as a result of low CIGs and areas of patchy fog. There could be some areas of dense fog, however confidence is low at the moment. Showers will continue to taper out of the area overnight. Otherwise expect northeasterly flow behind the front and varying broken to overcast decks. && .MARINE... Issued at 1252 AM CDT Thu May 7 2026 A cold front will move into the coastal waters this morning before stalling and lifting back north into the weekend. Another cold front will push back offshore late Sunday with a moderate north flow anticipated Monday. && .FIRE WEATHER... Issued at 1252 AM CDT Thu May 7 2026 A cold front currently bisecting the CWA will move into the coastal waters before stalling. It will be the focus for additional rain Friday and into the weekend as an upper level system moves in out of the west. && .LCH WATCHES/WARNINGS/ADVISORIES... LA...None. TX...None.
