    Areas affected...eastern ND and far northwest MN

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

    Valid 260649Z - 260815Z

    Probability of Watch Issuance...40 percent

    SUMMARY...A swath of strong to severe gusts may occur across a
    portion of eastern North Dakota into far northwest Minnesota before
    dawn. With the threat area likely to be confined, a watch is not
    currently planned. But it could be considered if greater intensification/organization becomes evident.

    DISCUSSION...A small cluster from Eddy to Stutsman Counties in
    east-central ND may be maintained to the east-northeast towards a
    portion of the Red River Valley before dawn. This cluster has
    evolved into a more north/south-orientation with recent convective
    development along its southern flank. This is nearly perpendicular
    to the deep-layer shear vector and enhanced 2-7 km AGL westerlies
    sampled in recent BIS VWP data. NDAWN observations confirm a 10-13 F temperature gradient within the small cold pool and unperturbed warm
    sector ahead of the outflow. This setup may yield a swath of strong
    to severe gusts in a focused corridor over the next 2-3 hours.
