875 FXUS64 KLIX 141136 AFDLIX Area Forecast Discussion National Weather Service New Orleans LA 636 AM CDT Wed May 14 2025 ...New AVIATION... .SHORT TERM... (Today through Thursday) Issued at 300 AM CDT Wed May 14 2025 Upper low/trough extended from eastern Kentucky to Florida this morning with another trough from Montana into California. Upper ridging was along the lee side of the Rockies. At the surface, low pressure was centered over the Oklahoma Panhandle with a warm front eastward and a dry line southward. Locally, skies were clear to partly cloudy at 3 AM CDT with temperatures between 70 and 75 with light south winds. Mid level ridging will build into the western Gulf and the lower Mississippi River Valley through Thursday. Onshore winds will continue to pump warm and moist air into the area. No significant chance for precipitation through Thursday. High temperatures today should be at least as warm as on Tuesday, in the middle and upper 80s, but wouldn`t rule out 1 or 2 spots touching 90. Forecast soundings would indicate that highs Thursday should be about 3 degrees warmer, which should put most areas in the lower 90s. This would be the first 90 degree days of the season for much of the area. Overnight lows tonight should be similar to this morning. && .LONG TERM... (Thursday night through Tuesday) Issued at 300 AM CDT Wed May 14 2025 Upper ridging becomes centered over the Gulf Friday and remains there through most or all of next week. A northern stream shortwave flattens it somewhat over the lower Mississippi River Valley on Saturday, and again around the middle of next week. That could push a frontal boundary far enough southward to potentially produce isolated showers or storms over southwest Mississippi Saturday afternoon, but that is pretty much the only chance of precipitation across our area of responsibility over the next 7 days. Temperature-wise...welcome to summer. Above normal temperatures are expected through the period with highs in the lower 90s across most of the area away from the immediate coast. Overnight lows will be mainly in the 70s. Those readings are generally 5 to 8 degrees above normal, and there really wasn`t a good reason to make significant changes to the NBM temperature forecasts. && .AVIATION... (12Z TAFS) Issued at 632 AM CDT Wed May 14 2025 Patches of ceilings around FL015 should mix out or lift to FL030 or above by mid-morning at all terminals. Most of the afternoon will see VFR conditions at all terminals. Winds are likely to be gusty at most terminals with sustained winds around 15 knots and gusts to 22 to 25 knots. Those winds should relax somewhat around sunset but not go completely calm. MVFR to IFR ceilings will again be possible between about 08z and 14z Thursday. && .MARINE... Issued at 300 AM CDT Wed May 14 2025 Will keep the Small Craft Advisory and Small Craft Exercise Caution headlines in place over the western waters through 18z today. May need another round of SCEC headlines overnight tonight into Thursday. For most of the remainder of the forecast period, winds should generally be in the 10 to 15 knot range, give or take a couple knots. && .PRELIMINARY POINT TEMPS/POPS...
