New AVIATION
SHORT TERM
(Saturday through Sunday)
Issued at 135 AM CDT Sat Jul 27 2024
Upper trough axis has maybe drifted a little further to the north and west over the last 24 hours. Best upper forcing has retreated a little further north and west as well but best atmospheric moisture in the form of higher PWATs remains across our southern and eastern half. Precipitation today should be more scattered in nature as just not seeing widespread precipitation coverage the the NBM is trying to suggest will occur today so have shaved pops back to high chance variety across our entire region. Given the high moisture output, where these storms form they will continue to be prolific rainfall producers but we should not see the concentrated areas of heavy rainfall as we saw Friday Morning necessitating the need for a Flood Watch. Pulled pops back to low end chance variety areawide early this evening and then slight chance variety across our southeast half by late evening and through sunrise Sunday Morning.
The upper trough begins to lift out into the Middle Miss and Tenn Valleys during the day Sunday but not before we see scattered convection once again across a majority of our region with the exception of our far northwest zones. Convection on Sunday should be tied more towards daytime heating and thus we may see a return to some high temperatures in the lower 90s for Sunday, a sign of things to come for the upcoming work week with precipitation chances coming to an end. More of that in the Long Term Forecast Discussion below.

LONG TERM
(Sunday Night through Saturday)
Issued at 135 AM CDT Sat Jul 27 2024
Upper ridging begins to build in from the west and south by Monday and that should bring an end to the inflated precipitation chances and a return to more normal late July temperatures. Held onto slight chance pops across our far east and southeast but the forecast is precipitation free Tuesday through at least Thursday.
Upper ridging will only build upstream from our region during this period which will help to crank up the temperature as well with afternoon highs Tue through Fri ranging in the middle to upper 90s across our entire region.
Given how wet we've been recently, good bet we will be dealing with higher dewpoint temperatures which combined with increasing ambient temperatures will result in oppressive heat in the form of higher heat indices much of next week as well. We should see at least Heat Advisory criteria with heat indices near or exceeding 105 degrees beginning across at least a portion of our region on Monday and becoming more areawide Tue thru Thu of next week.
By Friday into Saturday, we may see the upstream upper ridge retrograde enough into the Intermountain West to induce northwest flow aloft across the Southern Plains and thus, perhaps a frontal intrusion late in the forecast period. Lots of time to diagnose this rarity for early August but did include slight chance pops across our northern third on Friday and across all but our southern third for Saturday.

AVIATION
(12Z TAFS)
Issued at 558 AM CDT Sat Jul 27 2024
Compared to the 06z TAF package, increasing number of MVFR, IFR and LIFR flight conditions across the airspace, impacting local terminals. RA/SHRA has increased in coverage across the I-30 corridor terminals over the last hour. This will start to work across KTXK as the 12z TAF package begins. This should back build through the afternoon with SHRA and some VCTS expected further south. Main concern through the early morning will be the low CIGs and developing convective showers. There should be some gradual lifting of the terminal CIGs before falling again after 00z.
