New AVIATION

SHORT TERM
(Tonight through Monday night)
Issued at 126 PM CDT Sun Jun 2 2024

Confidence in shower and thunderstorm chances remains low this afternoon and evening across the region. We will keep a low chance for showers and storms in the forecast out west across far western Val Verde county to account for any activity that develops over the lower Trans-Pecos region. In addition, the complex of storms currently over northwest Texas could survive and make it into portions of the northern Hill Country and nearby I-35 corridor.
Otherwise, look for another warm night with low temperatures mainly in the 70s. On Monday, temperatures continue to nudge upward and we could be close to Heat Advisory thresholds across portions of the Rio Grande plains south of Del Rio into the San Antonio Metro area.
There will also be another low chance for showers and storms across the Hill Country and I-35 corridor north of San Antonio as a weak upper disturbance moves across north Texas.

LONG TERM
(Tuesday through Sunday)
Issued at 126 PM CDT Sun Jun 2 2024

Rain has basically been removed from consideration in the long term.
A weak perturbation is still shown in the 12Z ECM data for Tuesday afternoon/evening and repeating again Wednesday, but the GFS has trended with the NBM and lowering rain chances to being unworthy of mention. As heights aloft build east into the west half of TX, the H7 winds turn more westerly and remove the moisture that might get have gotten convection going in the northerly flow aloft. Instead, we'll get more sunshine and heating as is shown in the MEX MOS trends for the middle of the week. Highs will likely reach 100 for the SAT area and will potentially get there for the first time this year around Austin. However, we'll stop shy of that forecast as we noted a pretty good amount of cumulative rain totals of 1.5 to over 3 inches in the past 5 days which should consume some of that heating with evapotranspiration. Heat index values already have jumped above 100 degrees over the Coastal Prairies today and this will likely trend higher into advisory levels by Tuesday. Some of the Apparent T values might suggest we get into another excessive heat category, but this may settle out as the air gets drier each day. Pattern-wise, our hottest two days might be Wednesday and Thursday with the mid and upper level ridges parked over Central TX. On Friday, the H7 ridge axis goes east and potentially opens up a deeper marine layer for a temperature trend reversal. However, ridging above this level remains, and we may still see some near heat advisory conditions Friday. Hopefully by this time we begin to see some deeper inland intrusions of the sea breeze which typically makes the evening air much more tolerable. Just outside the 7-day forecast there remains some signs of upper ridge weakening and potential some convective potential, but the patterns with each model run do not show much consistency or agreement with one another.

AVIATION
(00Z TAFS)
Issued at 651 PM CDT Sun Jun 2 2024

VFR conditions will continue through around 05-06Z before MVFR ceilings return to the majority of the area through Monday morning.
IFR conditions are expected over portions of the southern Edwards Plateau and western Hill Country. Thunderstorms will remain north of AUS tonight with a low chance for showers or a storm near DRT later this evening. Chances for this are too low to mention in the forecast at this time. VFR conditions return late morning or early afternoon tomorrow.
