...New AVIATION...
.SHORT TERM... (This evening through Tuesday night) Issued at 616 PM CDT Mon Oct 13 2025
Benign weather continues for most of the week as broad upper level ridge generally remains centered across the Gulf South. The main effects from this high is lack of rain via strong subsidence and above normal temps. Current forecast keeps does not re-introduce rain chances through Friday, though could get some light showers coming in from the south along coastal areas late Friday. For those temps, mid/upper 80s each day. At least it`ll be cool at night and lower dewpoints keep humidity levels down.

.LONG TERM... (Wednesday through Sunday night) Issued at 616 PM CDT Mon Oct 13 2025
The upper level ridge that has been and will be dominating the forecast regime finally breaks down while shifting east Friday. Global models in decent agreement that a deep longwave trough will track across the mid section of the country, moving across the entire Mississippi Valley this weekend. Associated cold front along with some moisture return to at least bring the chance for scattered showers across the CWA. Should be cautioned that often times in the fall, global models `oversell` how much QPF we`ll see locally this far out. As the event approaches, they gradually show less and less rain...to the point where its isolated/scattered at best. Thus, am quite onboard with NBM output of 30 POPs in the forecast for next weekend.

.AVIATION... (00Z TAFS) Issued at 616 PM CDT Mon Oct 13 2025
A strong high pressure system centered directly over the area will keep skies clear and winds light. Prevailing VFR conditions will be in place through the next 24 to 36 hours.

.MARINE... Issued at 616 PM CDT Mon Oct 13 2025
Northerly offshore flow will persist today through early/mid-week thanks to high pressure over the eastern US and a developing low off the Carolina coast. This will keep conditions benign with light waves/seas and winds, as well as dry conditions. East to east- southeast flow does pick up some mid/late week, ranging 10 to 15 knots but will remain low impact and mainly dry into next weekend.
