    Areas affected...Northern/central Alabama...northern Georgia

    Concerning...Severe Thunderstorm Watch 601...

    Valid 071809Z - 072015Z

    The severe weather threat for Severe Thunderstorm Watch 601
    continues.

    SUMMARY...The environment will continue to become more favorable for strong/severe wind gusts. Some potential for storms to push farther
    south into Alabama exists as strong heating continues.

    DISCUSSION...Storms in northern Alabama have shown some signs of
    weakening over the past 1-2 hours. However, the downstream
    environment in northern Georgia continues to become more favorable
    for intensification of this activity. Strong/severe wind gusts will
    remain the primary threat this afternoon. Temperatures are
    continuing to approach or exceed 90 F from northern Georgia into
    central Alabama. MLCAPE has risen to 3000+ J/kg. Another linear
    segment of storms has recently developed in northeast Mississippi.
    These storms may be slightly elevated above the outflow from earlier
    storms. The main uncertainty is how far south any of the current and
    additional development will go this afternoon. Modifying the 12Z
    observed BMX sounding for current surface observations suggests that
    the boundary layer is virtually uncapped. Between the northeast
    Mississippi activity and signs of development along the southern
    fringe of outflow, storms may try to push farther south into parts
    of central Alabama. Should this occur, local extension of WW 601 may
    be necessary.
