Issued at 103 AM CDT Sun Jun 21 2026 - A MODERATE RISK of rip currents continues through midweek for Alabama and northwest Florida beaches. - Elevated rain chances remain in place through Thursday, particularly over interior counties. && .DISCUSSION... Issued at 103 AM CDT Sun Jun 21 2026 Currently, radar and satellite indicates that a remnant outflow boundary remains stalled over our Gulf waters, extending westward into southern Louisiana. Over the course of the day today, this outflow is expected to slowly lift northeastward as high pressure builds over Florida and helps to strengthen our low-level southwesterly flow. As this boundary lifts northeastward, it will help to serve as a low-level focus for scattered to numerous showers and storms to develop along. Latest CAMs suggest that convection should start to fire around, or a little after, daybreak across our coastal counties this morning. By the afternoon, the best convective coverage is expected to be focused over interior counties, with rain chances decreasing along the coast. Not anticipating any severe weather with this activity due to weak shear, although gusty downburst winds cannot be ruled out in storms that manage to cluster together. Additionally, the scattered nature of these storms, as well as faster storm motions, should help to limit flash flood potential. That being said, with how saturated the area is, 1hr Flash Flood Guidance generally sits at around 1.5-2.5 inches across much of the area and 3hr FFG is around 2.5-3.5 inches. And with PWATs still around 2 inches, storms could still be efficient rainfall producers. The 3 hr QPF ensemble max from the HREF does have a few isolated pockets of around 2-5 inches across the area. Therefore, cannot rule out some localized flooding concerns as we go through the day today. The synoptic pattern becomes rather persistent for most of the upcoming workweek. A generally light westerly to northwesterly upper- level flow pattern will be in place through Thursday as our local area remains sandwiched between an upper ridge over the Gulf and upper troughing over the Great Lakes. The problem with this type of flow pattern this time of year is that embedded shortwaves will try to move into the area from the northwest, which could allow for upstream complexes/MCS's to push into the local area. We are starting to see this possibility on some of the latest 00z CAMs, where they try to push an MCS into the area Monday afternoon/early evening. Although guidance tends to struggle with these types of complexes (i.e. strength and timing), the general consensus is that storms should be weakening upon arrival. Although the environment will be very unstable (CAPE values possibly exceeding 3000 J/kg in spots), shear values will likely remain around 20 knots or less, suggesting that the complex should be outflow-dominant by time it arrives. And with subsident effects from the nearby ridge along with steady (or even possibly rising) heights, am not anticipating much in the way of storm redevelopment/MCS maintenance. All that being said, if the complex does manage to make it into our northwestern counties, storms (or even just the outflow itself) may be capable of producing gusty winds to around 40-60 mph. Additional MCS potentials may be possible through Thursday as the overall westerly/northwesterly upper-level pattern remains prevalent. Rain chances remain rather elevated for midweek as more potent shortwaves attempt to push in. By Friday, the ridge is expected to build northward into the area. This will help to lower rain chances for Friday and into the upcoming weekend. Highs through the period will generally be in the upper 80s to low 90s. We should remain just below Heat Advisory criteria through the period, although most areas may see heat indices rise to around 100- 105. Lows will be in the 70s. A Moderate Risk of rip currents will continue through midweek, finally dropping to a Low Risk by late week. /96 && .AVIATION... (06Z TAFS) Issued at 103 AM CDT Sun Jun 21 2026 Patchy fog across interior southeast Mississippi and southwest Alabama overnight, with occasional visibilites dipping to LIFR levels, will quickly dissipate after sunrise Sunday. Numerous showers and thunderstorms developing along the coast by mid-morning Sunday will spread inland throughout the day, with coverage decreasing along the coast by early afternoon. Expect brief reductions in visibility in some of the heavier activity. Light and variable winds will become southwesterly 5-10 knots inland and around 10-15 knots closer to the coast. /22 && .MARINE... Issued at 200 PM CDT Sat Jun 20 2026 High pressure builds westward across the Florida Peninsula and into the central Gulf through the middle of next week. Light to occasionally moderate southwesterly winds will prevail through Monday then turn more westerly mid week. Seas generally 2 to 3 feet. /13 && .PRELIMINARY POINT TEMPS/POPS...
