    Mesoscale Discussion 0693

    Areas affected...parts of West Texas into Northwest Texas

    Concerning...Severe potential...Watch likely=20

    Valid 101755Z - 101930Z

    Probability of Watch Issuance...95 percent

    SUMMARY...Supercells are expected to form this afternoon with a
    threat of large hail, damaging winds, and perhaps a tornado.

    DISCUSSION...A surface front, reinforced by outflow from morning
    convection, is moving slowly southward across northwest Texas. A
    warm, moist airmass is present south of this front with temperatures
    in the mid to upper 80s and dewpoints in the mid 60s. This currently
    yields around 2500 J/kg MLCAPE. Additional heating/moistening may
    lead to even greater instability by mid to late afternoon.=20

    GOES East meso-sector satellite imagery shows some deepening cumulus
    and glaciating tops with a few storms already north of the frontal
    boundary. This indicates some ascent across the area. Therefore,
    within the next 1 to 2 hours, expect surface based strong to severe
    convection along and south of this boundary across northwest Texas
    as the remaining CIN erodes.=20

    The DYX VWP is currently sampling around 30 knots of 0-6 km shear.
    This shear is expected to increase through the day as the mid-level
    flow gradually strengthens. Therefore, supercells are expected with
    a large hail threat initially, before growing upscale into a MCS
    with an increasing severe wind threat by this evening.

    Initial convection appears most likely where convergence is
    maximized near the intersection of the outflow and the front near
    Haskell and Shackelford counties in Texas.
