FXUS64 KMOB 200555 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 1255 AM CDT Wed May 20 2026 ...New DISCUSSION, AVIATION... .KEY MESSAGES... Issued at 1255 AM CDT Wed May 20 2026 - Rain chances increase throughout the week, especially over the western half of the forecast area. - Localized patchy dense fog will be possible late tonight into Thursday morning and late Thursday night into Friday morning. && .DISCUSSION... Issued at 1255 AM CDT Wed May 20 2026 Light southerly surface winds will occur through the remainder of the week as a surface ridge remains intact across the southeast states and northeast Gulf. Atmospheric moisture will remain moderate with PWATs generally ranging from 1.5 to 2.0 inches. A continuous stream of upper mini-shortwaves moving over the lower Mississippi river in a deep southwesterly flow will result in a steady increase in shower and thunderstorm activity throughout the week, with the highest chances of precipitation occurring along and west of I-65. Isolated to low-end scattered showers and storms are forecast this afternoon across our inland areas, followed by isolated to scattered showers and storms, potentially numerous over southeast Mississippi, for Thursday. Scattered to widespread showers and storms are then expected Friday and Saturday, again with the highest chances occurring along and west of I-65. The light southerly wind flow mentioned earlier persisting all week does maintain some boundary-layer moisture across our area that should result in patchy to areas of late night/early morning fog over the course of the week. Visibilities are expected to lower to between 1 to 3 miles across much of the area late overnight into early morning, with patchy dense fog not being ruled out. Due to low confidence in the specific locations potentially being impacted by areas of dense fog, we will just need to see how thing unfold before needing any Dense Fog Advisories. High temperatures inland will reach the middle 80s to lower 90s today and Thursday. These highs will be about 3 to 6 degrees above normal. Due to the increase in clouds and rain chances Friday and Saturday, highs will return closer to normal values. Lows however will remain steady through Saturday with upper 60s to lower 70s inland and middle 70s along the coast. These lows will be about 6 to 11 degrees above normal. /22 && .AVIATION... (06Z TAFS) Issued at 1255 AM CDT Wed May 20 2026 VFR conditions will gradually deteriorate this evening to IFR mainly along the I-10 corridor. Further north, conditions should remain VFR as high clouds from thunderstorms to our west move over the area. Some localized fog could temporary reduce visibilities mainly along the I-10 corridor and into interior southcentral Alabama. MVFR to VFR conditions should return during the morning with isolated to scattered showers and storms developing across inland Alabama and inland Mississippi during the afternoon. Temporary reductions in visibilities and ceilings could be possible with the strongest of storms. BB-8 && .MARINE... Issued at 109 PM CDT Tue May 19 2026 No impacts expected other than locally higher winds and seas possible near thunderstorms. /13 && .PRELIMINARY POINT TEMPS/POPS...
