DISCUSSION

Issued at 205 AM CDT Mon Sep 7 2026

Mid-level ridging will build into South Texas today as the center flattens out across the southern half of the CONUS early this week. Moisture will remain above normal (75th percentile), around 2.0" PWAT values. We'll maintain low shower and thunderstorm chances along the seabreeze over the inland Coastal Plains and Brush Country today and Tuesday with the enhanced moisture in place. Coverage and rain chances increase a tad midweek Wednesday and Thursday as weak mid-level disturbances move westward across the Gulf towards the Texas Coast. However, rain chances lower again towards the end of the week as another mid-level ridge moves from the Desert Southwest into Texas, increasing the heat risk.
