New AVIATION

SHORT TERM
(Today through Tuesday)
Issued at 217 AM CDT Mon Apr 15 2024

Southwesterly mid-level flow prevails across South-Central Texas through the short term as an upper-level low advances eastward from the Four Corners into the Central Plains. At the surface, a tightening pressure gradient thanks to a strengthening surface low on the lee side of the Rockies will promote a moderate to breezy south to southeasterly flow into tonight. Gusts late in the day into this evening may gust over 30 mph at times. With a very strong capping inversion in place across the area, not concerned for any surface-based convection development. However, some of the higher res guidance does indicate a slug of mid-level moisture above the capping inversion that moves over portions of the area into and through this evening in advance of the Pacific front. This could induce a few elevated showers and perhaps a stray elevated thunderstorm. Greatest chance for an elevated cell to become strong would be across the Southern Edwards Plateau, if it could tap into the instability above the capping inversion.

The Pacific front then arrives into South Central Texas from late overnight into Tuesday morning. Some shower activity could be induced along the front as well before dissipating into Tuesday afternoon.
Expect for the front to get near the I-35 corridor before stalling. A dry westerly flow will be in place on the western side of this boundary. With a combination of very low humidity into the single digits and some occasional gustiness out west, near critical fire weather conditions are likely across the Rio Grande Plains, and the western Hill Country through Tuesday afternoon. For locations east of the boundary, they will remain within a humid air mass. The drier air out west will efficiently warm and yield to hotter afternoon highs on Tuesday afternoon across those locations with many into the 90s.
Farther east, mid to upper 80s remain common.

LONG TERM
(Tuesday night through Sunday)
Issued at 217 AM CDT Mon Apr 15 2024

The stalled front is forecast to move back northwest Tuesday night, but potentially waffle back southeast as a dryline Wednesday afternoon into the northwest Hill Country, southern Edwards Plateau and Rio Grande. In the upper levels, a compact low is forecast to pinch off across Baja California and Sonora, Mexico Wednesday and Wednesday night, then open and dampen across south Texas Thursday night. Ahead of this feature, several GEFS members have been indicating showers and thunderstorms developing out of Mexico and into portions of the Rio Grande Plains and southern Edwards Plateau Wednesday night, associated with an impulse ahead of the upper-level low. A few ECMWF ensemble members were also indicating this. Forecast instability and shear parameters would support a few strong to severe storms along the Rio Grande Wednesday evening if convection did develop. As the aforementioned upper level disturbance dampens east across the area, a few of the GEFS and ECMWF members were also keying in on late Thursday afternoon and evening as another potential for showers and thunderstorms across the Rio Grande Plains, and then weakening into the Hill Country and possibly I-35 corridor late Thursday evening. We will continue to refine rain chances and severe potential for late Wednesday and late Thursday over the coming days.

Beyond Thursday the forecast confidence remains low. In general, global models continue to indicate a polar cold front sometime over the weekend, but there remains a large spread in the guidance on when, although slightly more clustered around Saturday evening than this time yesterday. Rain chances will likely increase for a portion of the weekend as details in the next system and cold front emerge over the upcoming week. As the forecast is refined, we will also monitor for severe storms and heavy rainfall potential next weekend.

AVIATION
(12Z TAFS)
Issued at 631 AM CDT Mon Apr 15 2024

MVFR, perhaps brief IFR, ceilings continue this morning with a deck of low stratus. Expect for ceilings to improve to VFR levels into this afternoon but skies will stay mostly cloudy at most locations.
Moderate to breezy southerly to east-southeasterly winds develop this afternoon and continues through much of tonight. Gusts around 25 to 30 knots are possible. Low stratus redevelops tonight with returning MVFR to IFR ceilings. A Pacific front could result in a few nearby showers for KAUS into Tuesday morning. Winds towards the end of the TAF period, especially at the 30 hr TAF sites, feel the influence of the approaching front by subsiding and shifting in direction with time.
