    Mesoscale Discussion 0630

    Areas affected...portions of southwestern and south-central Texas

    Concerning...Severe potential...Watch possible=20

    Valid 010123Z - 010400Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A localized wind and large hail threat will be possible
    through late this evening as supercells move out of Mexico across
    the Rio Grande.

    DISCUSSION...Storms are noted to be occasionally intense on
    satellite and radar across the eastern Sierra Madre in Mexico this
    evening. Hi-res CAM guidance suggests that a few of these storms may
    persist and move across the Rio Grande into the Edwards Plateau
    region and perhaps portions of south-central Texas. The air mass
    across southern Texas is moderately unstable with strong deep layer
    shear ahead of the ejecting wave to the west across Baja California.
    Storms would likely be elevated in nature, given diurnal inversion
    layer, with the main hazards being large hail and strong to severe
    wind. Given some uncertainty in thunderstorm maintenance and the
    localized nature of this threat, a watch remains uncertain. Trends
    will be monitored through the evening.
