Isolated severe thunderstorms are forecasted for Tuesday across parts of the Texas Caprock, northwest Texas, and far southwest Oklahoma. These storms are expected to produce hail and strong gusts during peak heating periods.


        • Texas and Oklahoma: Concentrated from the Texas Caprock eastward through northwest Texas and into far southwest Oklahoma.


        • Hail and Strong Gusts: Potential for hail and damaging wind gusts during the most intense periods of storm activity.


        • Peak Heating: Focus on Tuesday afternoon when solar heating is at its maximum.


        • Weather Patterns: The region is under a northwest flow regime stemming from the Rockies to the East Coast, influenced by a significant shortwave trough traversing the Upper Mississippi Valley, Great Lakes, and Ohio Valley.
        • Atmospheric Dynamics:
          • Instability: Surface heating on Tuesday will help generate pockets of instability, particularly across northwest Texas. Forecast soundings indicate MUCAPE (Most Unstable Convective Available Potential Energy) values approaching 1500 J/kg. This level of instability is conducive to thunderstorm development.
          • Shear and Lapse Rates: Effective shear around 40 knots and steep mid-level lapse rates exceeding 8 C/km are forecast. These conditions support the development of organized convection, including supercells, which are efficient hail producers.
        • Surface Observations:
          • Frontal Dynamics: A surface trough will extend from Lake Huron to northwest Texas. Alongside this, a frontal boundary will stretch southwest-northeast, acting as a focus for storm initiation. Near this frontal boundary, especially south of the developing low over the Texas Panhandle, conditions will be ripe for severe storm development.
        • Practical Tips:
          • Target Area: For those chasing or observing, the area near the frontal boundary in northwest Texas will likely offer the best opportunities for severe storm observation. This region will experience the intersection of sufficient moisture, instability, and lift required for severe thunderstorms.

        Impact: Given the forecast conditions, there’s a heightened potential for hail and strong gusts. The dynamics near the frontal interface will be crucial for storm development, making this area the place to watch.
