150 FXUS64 KMOB 282346 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 645 PM CDT Tue May 28 2024 ...New AVIATION... .AVIATION... (00Z TAFS) Issued at 645 PM CDT Tue May 28 2024 VFR conditions are expected through Wednesday afternoon as high level clouds traverse the region. Calm or light and variable winds overnight become northeasterly to easterly at 5 knots Wednesday morning, shifting southeasterly along the coast in the afternoon. /22 && .PREV DISCUSSION... /issued 247 PM CDT Tue May 28 2024/ ..New NEAR TERM, LONG TERM, MARINE... NEAR TERM... (Now through Wednesday) Issued at 244 PM CDT Tue May 28 2024 An upper trof over the eastern states amplifies a bit through Wednesday while a series of shortwaves continue to move across the forecast area within the base of the upper trof. A surface ridge extending from the northern Plains into the southeast states shifts a bit eastward through Wednesday. This promotes a primarily dry northerly surface flow, although the slight movement of the surface ridge allows for a southerly flow to develop Wednesday afternoon from near the coast of the western Florida panhandle into southeast Mississippi, aided by the sea breeze. Deep layer moisture begins to improve on Wednesday mainly over the western half of the area which may be sufficient to allow for isolated to possibly scattered convection to develop in the afternoon over southeast Mississippi and much of southwestern Alabama along the weak convergent zone created by the southerly flow. For the rest of today, have made some minor adjustments to daytime highs and dewpoint values. For tonight, lows range from the lower 60s well inland to around 70 at the immediate coast. Highs on Wednesday look to be mostly in the lower 90s. A moderate risk of rip currents this afternoon will be followed by a low risk for tonight and Wednesday. /29 LONG TERM... (Thursday through Tuesday) Issued at 244 PM CDT Tue May 28 2024 A broad trough aloft generally remains draped down the East Coast late in the week with ridging just west of the local area. Subtle shortwaves pivot across the region between these two features aloft through that timeframe. Meanwhile, down at the surface, a front continues to meander over our coastal waters (or right along the coastline) as a surface high over the Great Lakes spills south into the region. As the surface high drifts south on Friday, surface winds begin to take on a southerly component. The ridge aloft also begins to amplify as it slides overhead by Friday afternoon. Coverage will be isolated at best on both Thursday and Friday (generally in the afternoon through early evening hours) given the combination of daytime heating, weak forcing from the shortwaves cruising through the region, and the weak surface boundary wobbling around near the coast. Coverage of showers and storms begins to increase as we roll into the weekend. The pattern aloft becomes somewhat chaotic with the potential for several shortwaves to move around the ridge over Mexico and pivot through our region. Timing out these individual features aloft this far into the future is difficult in this pattern, but it will help to increase rain chances over the weekend and into early next week. Expect increasing onshore flow leading to higher moisture levels as the aforementioned surface high drifts into the western Atlantic early in the weekend. While dewpoints will increase through this timeframe, daytime highs will be somewhat cooler given the higher coverage of showers and storms. We don`t anticipate a washout this weekend nor early next week, but there will certainly be waves of showers and storms in this active pattern. Beach Note: Rip current risk remains LOW Thursday through Saturday. RCMOS probabilities indicate an increasing likelihood of the rip current risk increasing to a MODERATE by Sunday and Monday. 07/mb MARINE... Issued at 244 PM CDT Tue May 28 2024 No impacts are expected through the period with the exception of higher winds and seas near storms. A light offshore flow develops tonight then becomes southeasterly on Wednesday. A light to moderate southeasterly flow prevails for Thursday through Sunday. /29 && .PRELIMINARY POINT TEMPS/POPS...
