    Concerning...Severe Thunderstorm Watch 197...

    Valid 072223Z - 080000Z

    The severe weather threat for Severe Thunderstorm Watch 197
    continues.

    SUMMARY...The risk for large to very large hail (maximum hail
    diameter 1.5 to 2.5 inches) will continue through the early evening.

    DISCUSSION...Visible satellite imagery shows a north-south oriented
    cluster of storms near and east of the dryline from 35 mi
    east-northeast of San Angelo, TX to 45 mi south-southwest of Altus,
    OK. Surface analysis indicates a very moist/warm airmass across the
    area with temperatures in the 90s and dewpoints in the upper 60s to
    lower 70s observed on several West Texas Mesonet sites east of the
    ongoing storms. Although low to mid-level flow is modest, 50-kt
    300-mb flow will enable storm organization and supercells will be
    the preferred storm mode of the stronger updrafts through the early
    evening. Large hail will be the primary severe hazard through the
    early evening (~7pm) before the risk for severe gusts perhaps
    increases with collapsing cores into the late evening hours in the
    presence of steep 700-500 mb lapse rates.
