Area Forecast Discussion National Weather Service Austin/San Antonio TX 213 PM CDT Mon Jun 14 2021 .SHORT TERM (Tonight through Tuesday Night)... Scattered Cu clouds are covering almost the entire area of South Central Texas. As of this writing, temperatures range from the upper 80s to upper 90s. With dewpoints in the lower 70s mainly along and east of Interstate 35, expect heat index values in the 102 to 108 range for the rest of this afternoon. Otherwise, dry for the most part with chances for showers and isolated thunderstorms across the northwest part of Val Verde County as an outflow boundary moves across that area followed by a stronger complex of storms over the San Angelo area pushing to the southwest. The other area that could see a shower or two and maybe a thunderstorm is the far southeast portion of the area. Partly cloudy skies are expected for tonight into Tuesday morning with lows in the mid to upper 70s. Can't rule out overnight and early Tuesday morning showers across the Hill Country and areas along and east the I-35 corridor as an outflow boundary pushes to the south and interact with the moist airmass that resides across the southeast and Coastal Plains areas. A new round of showers and thunderstorm is forecast for the far southeast of South Central Texas on Tuesday afternoon. The interaction of a lingering outflow boundary and elevated moisture will combine to generate scattered showers and isolated thunderstorm. Highs are expected to reach the lower 90s across the Hill Country to mid 90s along the I-35 corridor and up to 99 degrees along the Rio Grande. Heat index values are expected to run around 102 to 108 mainly along and east of I-35 for the afternoon period. Northeast winds 5 to 10 mph are forecast for most areas with a southerly flow along the Rio Grande. && .LONG TERM (Wednesday through Monday)... The beginning of the long-term forecast should begin mostly dry across all areas with only a very small chance of rain across the far southeastern counties on Wednesday. High temperatures Wednesday through Friday should be in the lower to upper 90s for most locations. For the weekend, any moisture/development with the system near the Bay of Campeche is expected to move well east of our area. This should leave us mostly dry and warm with temperatures expected to be in the middle 90s to 103-105 degrees. The warmer temperatures should be in the southwestern counties and locations closer to the Rio Grande. The blend held onto some low PoPs for the eastern counties this weekend, but knocked those down given the agreement in the guidance from the medium range models. && .PRELIMINARY POINT TEMPS/POPS...
