Areas affected...eastern ND and far northwest MN

Concerning...Severe potential...Watch possible

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.
