    Areas affected...Northwest MO...Southern IA...Far West-Central KS

    Concerning...Tornado Watch 65...

    Valid 030100Z - 030230Z

    The severe weather threat for Tornado Watch 65 continues.

    SUMMARY...Threat for damaging wind gusts as well as embedded
    tornadoes continues across Tornado Watch 65.

    DISCUSSION...Well-organized MCS continues to progress northeastward
    into far northwestern MO. Recent surface observations from FNB (near
    the NE/KS/MO border intersection) reported a 47 kt gust as the
    northern end of the MCS moved through. Strong gusts will remain
    possible as the system moves across northern MO/southern IA. Frontal circulations attendant to the stationary front draped across
    southern IA (from DVN southwestward to near FNB) may augment the
    downdrafts associated the convective line, leading to slightly
    higher threat for damaging wind gusts along the front.

    Farther south, cold pool amalgamation appears to be taking place
    between the more northerly MCS and the one that progressed across
    central KS. Locally enhanced threat for damaging wind gusts (and
    perhaps a tornado) exists near the inflection point of these newly
    joined convective lines (near Coffey and Osage counties in KS). In
    this area, remnant meso-low associated with the book-end vortex of
    the convective line could augment low-level shear and/or briefly
    enhance updrafts.

    Areas affected...Parts of southeast Texas...western and northern Louisiana...western Mississippi and southeast Arkansas

    Concerning...Tornado Watch 53...54...

    Valid 132039Z - 132215Z

    The severe weather threat for Tornado Watch 53, 54 continues.

    SUMMARY...Severe weather potential continues to gradually ramp up.
    This appears likely to include a few supercells with increasing
    potential for a strong tornadoes through 5-6 PM CDT.

    DISCUSSION...Gust front continues to advance eastward around 40 kt,
    into the Sabine Valley and upper Texas coast, accompanied by a
    narrow broken line of intense convective development. This activity
    is preceded by scattered discrete storm development, and an evolving
    cluster of storms centered around the Monroe LA area.

    It appears that severe weather potential, including potentially
    damaging wind gusts and a risk for tornadoes, will maximize in a
    corridor near/north of Natchitoches through the Monroe LA area
    between now and 22-23Z.

    20Z surface observations indicate that rapid strong 2-hour surface
    pressure falls have become focused across the Monroe LA into Greenville/Vicksburg MS vicinity, where further boundary layer
    destabilization associated with warming and moistening may support
    intensifying boundary-layer based thunderstorm development during
    the next few hours. Beneath a 50 kt southerly 850 mb jet, large
    clockwise curved low-level hodographs will support increasing
    potential for tornadoes. A couple could be strong.
