DISCUSSION

Starting out late this morning looking at regional observations and satellite, rather quiet and calm! Seeing mid-level StratoCu breaking up revealing developing low-level Cu from surface heating. In regards to temperatures, the deterministic NBM remain on track with little bump needed for today, as we'll be right around/near climo norms for highs. Few key items to monitor later today taking a deeper dive into guidance, mostly in regards to PoPs. Did introduce a minor uptick in 15-20% PoPs inland for today, which will need to be monitored following the developing and northward drifting seabreeze. It'll be a battle between if sfc confluence from environmental westerly flow and the northward moving seabreeze can support enough localized ascent to overcome broad suppression from the nearby high, as recent HRRR sim RF trends illustrate. Even combined with REFS trends, still seemed enough to add in a slight uptick for interior regions today. Model soundings illustrate what was mentioned with a subtle, yet notable low to mid-level tropospheric subsidence inversion allowing for a slither of H8-H7 steep lapse rates from compressional warming, a well-mixed PBL supporting available instability later today. Something to keep an eye on, but if any activity develops, will dissipated around sunset.

Quiet tonight, then temperatures bump up tomorrow which will be the start of a distinct warming trend that will continue into the weekend and into next week. Only additional focus for tomorrow was on transitioning NW flow as the ridge drifts west across SE LA, this, combined with the northward drifting seabreeze may aid in greater confluence for isolated thunderstorm development. As of now, the best potential will generally be along the US45 corridor from Wayne Co, SE to Baldwin. This will be something to closely watch with ample low-level instability, hail-growth CAPE in the 700-1000j/kg range and downward flux momentum transport potential to bring down strong gusty winds, especially for nearshore marine areas. For now, introduced isolated/15% PoP coverage in this region as deterministic NBM has nothing, but don't want to sell too much on the idea for now, but enough to mention.

Next focus will be the growing heat concerns, especially this upcoming weekend as afternoon heat indices climb into the low to mid 100's Friday and into this weekend, to the upper 100's to 110's next week bringing an increased possibility of heat headlines during this time frame. Given the time of the year for those enjoying beach activities this weekend and next week, will be messaging heat safety precautions.

Additionally this weekend into next week, keeping an eye on the tropics given NHC's latest low-probabiility of development in the NE Gulf, particularly near the FL Big Bend area. Still many uncertainties here between long-range and AI guidance as a inverted trough parades NW from the Caribbean into the SE Gulf with time. As with most systems, it's a strong balance game between many key features that'll directly reveal the degree of, or if, any tropical development can occur in this region. 1) The lead ridge of high pressure, currently enhancing westerly 850-200mb shear across the Caribbean will build NW with time into the northern Gulf, How strong this ridge, and where it will end up will directly result in how much southerly shear will impact the system hindering, or slowing development. Both the ECMWF and GFS solutions are a bit split here, with the GFS being the weaker solution but newer trends in EPS guidance starting to nail down some potential for development near/around the FL Big Bend the the CMC being split between the two. Additionally, Deep Mind AI guidance hints at something relatively weak in the Big Bend, which then feels the developing east-coast trough and swings east across the FL peninsula out to the Atlantic Coast. This seems a bit more plausible at the moment. Overall, for now here locally, just something to keep an eye on and should changes occur, will be providing updates. KLG

AVIATION
(00Z TAFS)
Issued at 650 PM CDT Wed Jul 15 2026

VFR conditions will prevail through Thursday afternoon outside of brief reductions in ceilings and visibilities in and around evening showers and thunderstorms across interior southwest Alabama north of Highway-84. Light westerly to northwesterly winds starting around mid-evening will increase to 5-10 knots Thursday morning with a few gusts up to around 17 knots. /22

MARINE
Issued at 1201 PM CDT Wed Jul 15 2026

Light westerly flow remains in place across nearshore and outer Gulf waters today and Thursday, with brief nearshore wind shift from the WSW to SW each afternoon following daily seabreeze development. Will monitor nearshore waters today and Thursday if inland convection can ignite along the aforementioned seabreeze and drift southeast back towards the coast, along progressive NW flow developing as a ridge of high pressure drifts west across SE LA. This could introduce an isolated risk of gusty, erratic wind gusts in any locally stronger storm. Seas generally 1-2 for Gulf waters, <1 ft for protected waters thru the rest of the week and into the weekend. KLG
