Areas affected...far northeast North Dakota and northwest Minnesota

Concerning...Severe potential...Watch unlikely

Valid 261639Z - 261815Z

Probability of Watch Issuance...20 percent

SUMMARY...An isolated hail threat will exist through early afternoon
across far northeast North Dakota and northwest Minnesota.

DISCUSSION...An elevated supercell has shown some sign of
strengthening in the last hour as it moves from Manitoba into
northeast North Dakota. This supercell is elevated, within the post
outflow boundary airmass at this time. Already weak forcing, from
weak isentropic ascent, is expected to weaken further into the early
afternoon as low-level flow dissipates. This casts some uncertainty
as to the fate of this activity. However, the downstream airmass is destabilizing and temperatures near 90 with dewpoints in the 70s may
be sufficient for surface-based storm development.

Given this uncertainty and isolated storm coverage, a watch is not
anticipated. However, if there are signs of surface-based transition
and/or additional storm development within the next 1 to 2 hours, a
watch may need to be considered.
