    Areas affected...New England

    Concerning...Severe Thunderstorm Watch 479...

    Valid 212029Z - 212230Z

    The severe weather threat for Severe Thunderstorm Watch 479
    continues.

    SUMMARY...A wind-damage threat will continue over the next few hours
    across parts of New England. A brief tornado could also occur.

    DISCUSSION...The latest mosaic radar imagery shows widely scattered
    strong to severe thunderstorms ongoing across parts of Vermont, New
    Hampshire into western and northern Maine. So far the convection has
    remained discreet. Some cells have maintained rotation with
    supercell characteristics, particularly across southern New
    Hampshire and southern Maine. These storms should continue to have
    wind-damage potential and could produce a brief tornado. There is
    still a chance for linear development as the storms move eastward
    across Maine late this afternoon into early this evening. If a cold
    pool does form, it would likely develop with the storms currently
    located from northern Vermont into southern Quebec. This line would
    progress eastward across western and northern Maine late this
    afternoon into early this evening, somewhat like the current HRRR
    solution. An increased wind-damage threat would be associated with
    any line that can organize.

    Areas affected...Northeast NM into the western OK/TX Panhandles

    Concerning...Severe Thunderstorm Watch 485...

    Valid 140353Z - 140530Z

    The severe weather threat for Severe Thunderstorm Watch 485
    continues.

    SUMMARY...Some threat for large hail and localized severe gusts may
    persist for another 1-2 hours. WW 485 has been extended to 06 UTC.

    DISCUSSION...Long-lived supercells continue to move southward across
    extreme northeast NM into the western TX/OK Panhandles as of 0345
    UTC. Modest weakening has been noted with a few of the supercells
    over the last 30-60 minutes, and this trend will likely continue as
    MLCINH continues to increase with time. However, with favorable
    instability and deep-layer shear and the presence of multiple
    long-lived supercell structures, some threat for large hail and
    localized severe gusts may persist for another 1-2 hours before
    MLCINH becomes too prohibitive and/or storms move out of the more
    favorable instability axis. With this potential in mind, WW 485 has
    been extended in time and is now scheduled to expire at 06 UTC.
