    Areas affected...Central Kansas

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

    Valid 050538Z - 050815Z

    Probability of Watch Issuance...40 percent

    SUMMARY...An isolated severe threat, with potential for wind damage
    and large hail, is expected to continue across central Kansas over
    the next few hours. Weather watch issuance will be possible as the
    cluster of storms approaches the eastern edge of WW 309.

    DISCUSSION...The latest high-resolution radar from Dodge City shows
    an MCS, with embedded bowing structures, located across
    north-central Kansas. Over the next few hours, this cluster of
    strong thunderstorms will continue to move southeastward into a
    pocket of moderate instability located from northern Oklahoma into north-central Kansas. The RAP is estimating MLCAPE along this
    corridor in the 2000 to 2500 J/kg range. In addition, the WSR-88D
    VWP from Dodge City has 0-6 km shear near 35 knots. And the RAP is
    analyzing a 30 to 40 knot low-level jet over west-central Kansas.
    This will continue to support a wind-damage threat associated with
    the leading edge of the stronger cells. Recently, a wind gust of 50
    knots was reported at Russell, Kansas. As the MCS moves
    southeastward, this caliber of wind gust will continue to be
    possible. Isolated large hail could also occur with the more intense
    cells as well.

    Mesoscale Discussion 1036
    NWS Storm Prediction Center Norman OK
    1026 AM CDT Wed Jun 14 2023

    Areas affected...Portions of far southeastern AL into southwestern
    GA

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

    Valid 141526Z - 141730Z

    Probability of Watch Issuance...60 percent

    SUMMARY...If supercells can be sustained, then large to very large
    hail and perhaps a couple of tornadoes may occur. Watch issuance is
    possible if thunderstorms strengthen further.

    DISCUSSION...Thunderstorms have recently developed across parts of
    southeastern AL along/south of a front and ongoing small cluster in south-central GA. This activity is being aided by a 20-30 kt
    southwesterly level jet and related warm air advection. Continued
    daytime heating of a very moist low-level airmass, and the presence
    of steep mid-level lapse rates, has already fostered around
    2000-3000 J/kg of MLCAPE. The latest VWP from KEOX shows a veering/strengthening wind profile with height through mid/upper
    levels, with 50-60 kt of westerly winds present at mid levels.
    Similar values of deep-layer shear will easily support supercells
    with any thunderstorms that can be sustained into parts of
    southwestern GA. Large to very large hail will be a concern, but a
    couple of tornadoes may also occur as the west-southwesterly
    low-level jet and 0-1 km SRH may modestly strengthen further through
    the afternoon. Signs of increasing supercell coverage/intensity may
    prompt watch issuance at some point in the next couple of hours.
