    Mesoscale Discussion 2116

    0635 PM CDT Fri Sep 08 2023

    Areas affected...Red River Region (OK/TX)

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

    Valid 082335Z - 090130Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Gusty winds are possible with convection this evening.
    Severe thunderstorm watch may be warranted if convection continues
    to increase.

    DISCUSSION...Upper anticyclone is slowly retrograding across the
    southern Rockies this evening. This is resulting in a gradual
    increase in northwesterly flow across the southern Plains with 500mb
    flow now on the order of 25-30kt along the Red River. Weak surface
    low is sagging south and a notable wind shift is now arcing from
    southwest OK-GYI-northeast of Dallas. Very hot surface temperatures
    are noted south of the boundary with surface readings still in
    excess of 105F. As a result, the boundary layer is very deep across
    this region, and PW values are seasonally high with values
    approaching 1.5 inches. 50+ temp/dew point spreads and high cloud
    bases appear favorable for gusty winds with convection that is
    gradually maturing along the front near the Red River. If this
    activity continues to organize there is some concern for a more
    organized wind threat, especially if convection propagates southeast
    along the frontal zone.
