Area Forecast Discussion National Weather Service Austin/San Antonio TX 622 AM CDT Sat Jun 12 2021

AVIATION. MVFR CIGs at the I-35 sites will lift to FEW-SCT VFR at all sites by midday. S-SE winds at 6 to 11 KTs prevail, except 10 to 15 KTs with gusts to 25 KTs at KDRT during the day. There is uncertainty on CIGs tonight at the I-35 sites as winds turn more to S-SW. Have MVFR CIGs at KSAT/KSSF while only SCT at KAUS. Regardless VFR is expected most of Sunday.

PREV DISCUSSION. /ISSUED 252 AM CDT Sat Jun 12 2021/

SHORT TERM (Today through Sunday) . Status Quo for today. Subtropical ridging centered nearby maintains a dry subsident airmass aloft with no rain expected. Surface low pressure in the Great Plains maintains a humid south-southeasterly lower level flow off the warm Gulf of Mexico and its sea surface temperatures in the mid 80s. Temperatures will be within a few degrees of normal with afternoon heat index values only mildly elevated.

On Sunday, the Subtropical ridging drifts to the northwest allowing a northerly flow aloft. This may allow a surface boundary to sag south into our area. With a little less subsidence, though a still moist airmass, weak upward forcing by the boundary and solar heating may result in very isolated showers and thunderstorms. There are some Hi-res models that show a few showers and thunderstorms over the Hill Country to along the Escarpment where forcing is enhanced by upslope flow. However, most other models show nothing at all. For now, will increase POPs a little for Sunday afternoon, however not enough to mention precipitation. Later forecasts will monitor trends for possible mention. Not much change in temperatures is expected.

LONG TERM (Sunday Night through Friday) . Hot and humid conditions persist. The upper ridge dominating the area will shift west monday allowing for a weak boundary to move into the eastern part of the state. Afternoon showers will be more limited to areas east of our CWA, but a few sprinkles in our farthest counties will not be out of the question. Little to no change in temperatures through the week with highs in the mid to upper 90s and overnight lows in the mid 70s.
