Concerning...Tornado Watch 226...

Valid 260121Z - 260315Z

The severe weather threat for Tornado Watch 226 continues.

SUMMARY...An isolated tornado and wind damage threat will likely
continue for a few more hours. The storms will move northward toward
the edge of WW 226. Although weather watch issuance is not
anticipated to the north the current watch, the situation will
continue to be monitored.

DISCUSSION...The latest radar imagery shows a band of strong
thunderstorms located from far northeast Oklahoma extending
southeastward to near Fayettville, Arkansas. Isolated discrete cells
are ongoing to the north of the line with one having a history of
producing tornadoes just to the west of the
Arkansas-Missouri-Oklahoma state line intersection. The RAP
continues to show moderate deep-layer shear across northeast
Oklahoma and northwest Arkansas with 0-3 km storm relative
helicities estimated in the 200 to 250 m2/s2 range. The wind profile
continues to support a tornado threat with small supercells that
develop to the northeast of the northwest-to-southeast band of
storms. A wind damage threat will also be possible with supercells
and with this band as well.
