863 FXUS64 KMOB 171144 AFDMOB Area Forecast Discussion National Weather Service Mobile AL 644 AM CDT Fri May 17 2024 ...New AVIATION... .AVIATION... (12Z TAFS) Issued at 637 AM CDT Fri May 17 2024 Scattered thunderstorms will continue to develop across the area throughout the morning and afternoon today. Gusty winds and hail will accompany strong to severe storms throughout the day. Ceilings will drop into the MVFR to IFR range this morning and stay there throughout much of the TAF cycle. Outside of thunderstorms, conditions will remain gusty along the coast through early afternoon. 07/mb && .PREV DISCUSSION... /issued 538 AM CDT Fri May 17 2024/ ..New NEAR TERM, SHORT TERM, LONG TERM, MARINE... NEAR TERM... (Now through Saturday night) Issued at 538 AM CDT Fri May 17 2024 An active and very complicated weather pattern will persist through Saturday afternoon as a couple more shortwaves eject northeast from a very slow moving positive tilt trough moving through the plains. A wake low has developed behind the initial wave of storms overnight, and a Small Craft Advisory is now in effect for today for all marine zones. The left over boundary from this convection will lift northward as a warm front throughout the day, and should provide a focus for additional thunderstorm development across our interior areas. The pre- storm environment in the warm sector after midday Friday south of a northeastward moving warm front will have sufficient MLCAPE values around 1,500 to 2,200j/kg. Deep layer shear values as high as 50-55kts are expected by Friday evening. Large hail and damaging wind gusts will be the main threats. The tornado threat, while non-zero, will be mitigated due to the weak low level shear values. The Storm Prediction Center has placed the entire area in a Slight Risk for severe storms for today. Another shortwave and associated MCS is expected to approach the area Friday this evening. These storms could again pose a damaging wind and large hail threat. Additional showers and storms are possible into Saturday as the approaching cold front slowly slips through the area. The multiple rounds of rain on already saturated grounds will create the risk for flooding through Saturday. WPC had a moderate risk across northwest portions of the area with a slight risk across the remainder of the area. A Flood Watch remains in effect for the entire area through 1PM Saturday. A High risk of rip currents is in effect through Sunday afternoon. /13 /22 SHORT AND LONG TERM... (Sunday through Thursday) Issued at 538 AM CDT Fri May 17 2024 The area dries out late in the weekend through the middle of next week. Weak ridging aloft builds into the region as a trough remains draped across the western Atlantic. This pattern results in northerly to northwesterly flow aloft developing overhead through early Wednesday. A surface high draped down the East Coast eventually nudges into the region early next week and onshore flow becomes established by Tuesday. A shortwave sliding across the central portion of the CONUS will cause the ridge aloft to briefly flatten toward the Gulf by mid-week. The bulk of the showers and storms associated with this shortwave will likely remain to our north on Wednesday and Thursday, although we can`t rule out some isolated storms by Thursday afternoon. Beach Note: Rip current risk remains HIGH on Sunday and eventually falls to MODERATE late on Sunday night. The risk remains MODERATE on Monday. RCMOS probabilities indicate that the risk should fall to a low on Tuesday through Thursday. RCMOS guidance does indicate a very brief bump to MODERATE is possible Tuesday afternoon for the beaches in northwest Florida. 07/mb MARINE... Issued at 538 AM CDT Fri May 17 2024 Moderate to strong southerly winds along with building seas will occur today due to the development of a wake low. An approaching front will bring additional showers and thunderstorms to the marine area late tonight through Saturday. A light offshore flow returns late in the weekend into early next week in the wake of the front. /22 && .PRELIMINARY POINT TEMPS/POPS...
