| Area Forecast Discussion National Weather Service Mobile AL 628am CDT Sunday September 13 2026 Issued at 626am CDT Sunday September 13 2026 Forecast remains on track. MM/25 Issued at 1206am CDT Sunday September 13 2026 A weakening upper trough over the southeastern states ejects off to the north on Sunday followed by an upper ridge building over the region through Monday. A weak surface trough extends into the forecast area on Sunday and looks to aid in isolated to scattered convective development mainly during the afternoon. The upper ridge remains over the region through Wednesday with a surface ridge over the northeastern states meanwhile building into the southeastern states. Subsidence associated with the upper ridge will suppress convective development while the building surface ridge sets up an easterly flow and ushers progressively drier air into the forecast area beginning Monday and becoming more pronounced Wednesday into Wednesday night. An interesting pattern sets up later in the period as an upper low/trough over the far western Atlantic, with an associated inverted surface trough, is anticipated to move to over or near the Florida peninsula on Friday. Am anticipating dry conditions to continue over the area on Thursday, then have gone with mainly slight chance probability of precipitation returning to the southern portion of the area on Friday. Highs on Sunday will be in the lower to mid 90s then trend to the mid to upper 90s for Monday and Tuesday. Heat index values on Sunday through Tuesday will be 100-106 with a few spots reaching 107. Highs on Wednesday through Friday will be mainly 90-95. Heat index values of 95-103 on Wednesday trend to the mid 90s for Thursday and Friday. A low risk of rip currents is anticipated from Sunday through Tuesday then increases to a high risk for Wednesday and Thursday. /29 Marine Issued at 1224am CDT Sunday September 13 2026 Light southwest to westerly flow prevails today.
