    A weak and diffuse surface boundary is presently straddling the
    I-20 corridor, which has made for some indecisive wind directions
    over the last few hours. Winds should more homogeneously come
    around to favor a southerly direction through the evening hours as
    this boundary is pushed back northward. Visible satellite imagery
    reveals cumulus bubbling in the vicinity of the Bowie cornerpost,
    but mesoanalysis shows enough lingering convective inhibition to
    greatly limit the storm potential. While a spit of rain will be
    possible over the next 1-3 hours, no precip chances are needed at
    TAF sites this evening.
    Late tonight, surface winds will continue to veer ahead of a
    stalling cold front which will be approaching the Red River. By
    mid-morning, winds from 230-260 degrees will be possible, but
    speeds under 15 kts will preclude any crosswind issues. An area of
    pretty robust lift is forecast to develop near and just north of
    the Red River very late tonight in response to a burgeoning low-
    level jet. Most model guidance indicates the mid-levels will
    remain just a bit too parched of moisture for this to result in
    elevated thunderstorm development. However, this afternoon's 3km
    NAM is convecting across central Oklahoma, likely in response to
    greater moisture within the zone of strongest ascent. We'll
    continue to advertise precip-free TAFs Friday morning across the
    Metroplex, and will monitor upstream observations and future model
    guidance this evening.
