    Areas affected...Eastern Dakotas...northern Minnesota

    Concerning...Severe Thunderstorm Watch 486...

    Valid 042209Z - 050015Z

    The severe weather threat for Severe Thunderstorm Watch 486
    continues.

    SUMMARY...Scattered severe thunderstorms will continue across ww486
    this evening.

    DISCUSSION...Upper ridge is gradually shifting east across the MS
    Valley. This is permitting a higher PW plume over the
    Plains/northern MN to gradually advance across the upper Red River
    region into the main body of ww486. Latest radar data suggests a
    very weak MCV may be embedded within a more elongated corridor of
    convection, just east of Jamestown ND, but this feature is subtle.
    With temperatures in the upper 80s to near 90F across
    convective-free areas, ample buoyancy is available for both the
    east-west, and north-south corridors to eventually advance across
    the remainder of the watch through the mid-evening hours. Hail and
    wind remain possible with this activity.
