FXUS64 KLCH 071817 AFDLCH Area Forecast Discussion National Weather Service Lake Charles LA 117 PM CDT Mon Apr 7 2025 ...New AVIATION... .KEY MESSAGES... - Skies will clear today as dry air filters in from the northwest. Expect slightly warmer temps each day with beautiful weather all week. - Dry cool front passage at the end of the week. No appreciable precipitation chances expected today through the forecast. && .SHORT TERM... (Today through Wednesday night) Issued at 350 AM CDT Mon Apr 7 2025 Finally, a calm and quiet short term forecast. Upper trof axis will cross the region today allowing dry airmass to filter in, clearing out skies from west to east. High pressure will settle in overtop the region in the wake of passing trof. Conditions will feel nice and cool today with only slightly warmer temps tomorrow. You cannot ask for a more beautiful start to the work week. Airmass will moderate in larger fashion Wednesday as highs return to the mid to upper 70s. Moisture starts to make a return but dewpoints should only hit the lower 60s. Not enough moisture or lift to bring back cloud cover, but a few low level puffy clouds can't be ruled out. Please get outside and enjoy the weather this week! 11/Calhoun && .LONG TERM... (Thursday through Monday) Issued at 350 AM CDT Mon Apr 7 2025 Still, a dry and quiet longterm period is in store. Thursday into Friday, an upper low is set to amplify and dive south out east- central Canada. The resultant strong northwest flow will send southward a dry cool front passage late Friday. No precipitation is expected and temperatures in the mid 70s to low 80s can be expected Thursday, Friday and Saturday. While daytime temps will be in the "warm" territory, slightly drier air will cause the end of the work week to feel rather pleasant. High pressure moves overhead and moisture/heat return Sunday into Monday. 11/Calhoun && .AVIATION... (18Z TAFS) Issued at 107 PM CDT Mon Apr 7 2025 Mid level clouds associated with the cold front to the east have now shifted across the Mississippi river leaving BKN stratocumulus decks around 3000ft with a few areas of MVFR CIGs. These will continue to erode and lift becoming SCT and VFR during the remaining afternoon hours. NW winds will continue with gusts 15-23kts before easing toward the evening hours as high pressure broadens overhead. Skies expected to clear tonight leaving all terminals VFR by nightfall. Potential exist for some radiational fog with unseasonably cool temperatures forecast overnight and clear skies. Limiting factor for fog formation will be the persisting NNW breezes, albeit much lighter through the dawn hours. 30 && .MARINE... Issued at 350 AM CDT Mon Apr 7 2025 North to northwest winds will prevail through the morning. The residual high swells and wave heights from the south meeting these north winds will create very short wave periods, resulting in steep seas through this morning. Winds and seas will gradually subside this afternoon and Tuesday as the surface high settles over the area. && .FIRE WEATHER... Issued at 316 AM CDT Mon Apr 7 2025 Northwest winds will bring much cooler and drier conditions for the first part of this work week. Minimum RH values today will be in the 40 to 45 percent range, 30 to 35 percent Tuesday. A warm and moistening trend begins Wednesday with very warm and humid conditions present again through the end of the week. && .PRELIMINARY POINT TEMPS/POPS...
