DISCUSSION

Issued at 1203 PM CDT Sat Jul 18 2026

An upper-level ridge across the north-central gulf coast to remain sandwiched between two areas of low pressure: one across the Texas panhandle and the other across the northeastern Gulf of America. The upper-ridge will remain firmly established across the region despite being squeezed by the westward drifting gulf low. By Monday, the prevailing ridge to be absorbed by a stronger ridge centered across Colorado, which will secure a dry pattern across the ArkLaTex through the forecast period ending Friday.

At the surface, high pressure centered across the northern gulf will maintain light and moist southerly flow through the weekend into early in the work week. Thus, with increased humidity values and subsidence aloft from the upper-ridge, high temperatures in the mid to upper 90s can be expected through Monday with heat index values near 105 degrees. As the upper-ridge strengthens, temperatures could approach 100 degrees on Tuesday and Wednesday with heat index values ranging from 105 to 110 degrees, prompting heat headlines.

A weak frontal boundary will drift south across the region through midweek allowing for slightly drier continental air to infiltrate the region from the north. Although temperatures may still climb into the mid to upper 90s, the slightly drier airmass could allow for lower heat index values, mitigating the need for advisories on Thursday and Friday. /05/
