The severe weather threat for Severe Thunderstorm Watch 137
SUMMARY...Strong/locally severe storms continue to advance across
northeastern and central Arkansas, where damaging winds continue to
pose severe risk.
DISCUSSION...Latest radar loop continues to show a fairly
well-organized bowing cluster of storms moving across northeastern
Arkansas and adjacent southeastern Missouri, with vigorous storms
developing eastward toward the Mississippi Valley just ahead of the
bow in a wing of warm advection.
Meanwhile, a second/organized cluster of storms is ongoing just to
the southwest, which will move northeastward across central Arkansas
at around 45 kt over the next 1 to 2 hours. These storms are most
intense in the vicinity of a west-to-east outflow boundary laid out
by the bowing cluster to the north, that has sagged southward into
the Little Rock area. A 62 kt gust has recently been reported near
Hot Springs with this cluster, and expect strong/possibly damaging
winds will affect the Little Rock metro area beginning within the
next half hour or so.
