960 FXUS64 KEWX 220638 AFDEWX Area Forecast Discussion National Weather Service Austin/San Antonio TX 138 AM CDT Sat Jun 22 2024 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Sunday) Issued at 138 AM CDT Sat Jun 22 2024 The center of the Subtropical Ridge drifts to the west over Texas today and Sunday while another tropical disturbance approaches the northeastern Mexico coast on Sunday. NHC has a 50% chance of tropical cyclone development. The airmass is subsident underneath the Ridge with most areas remaining rain free. However, on Sunday when the disturbance is closest, there is deeper moisture along and south of the US 90 corridor. As a result, expect some showers and thunderstorms to develop due to heating over those areas on Sunday. Seasonably hot high temperatures and heat indices are expected. && .LONG TERM... (Sunday night through Friday) Issued at 138 AM CDT Sat Jun 22 2024 The upper level ridge will be the main influence to the forecast across the region through the long term forecast. The forecast remains mostly dry. Low and high temperatures are forecast to increase next week. Humid conditions are also expected, and with the elevated dew points we will watch closely for heat index values pushing near or into Heat Advisory Criteria across portions of the region. && .AVIATION...
