Concerning...Severe Thunderstorm Watch 514...
Valid 160119Z - 160245Z
The severe weather threat for Severe Thunderstorm Watch 514
continues.
SUMMARY...An organized convective system probably will maintain
intensity with a continuing risk for strong to severe gusts as it
propagates southeastward through 9-11 PM CDT.
DISCUSSION...Convection has grown upscale into an organizing
convective system, including the evolution of a couple of notable
embedded meso-beta scale cyclonic circulations. One associated
southeastward cold pool surge is ongoing across/southeast of the
Yankton SD vicinity, at a forward propagation around 30 kt. To the
southwest, another southeastward surge across and southeast of
Broken Bow NE is a bit slower, around 20 kt, but the nose of a
nocturnally strengthening low-level jet (in excess of 30 around 850
mb) may begin interacting with this portion of the QLCS by 03-04Z.
Inflow of seasonably moist boundary-layer air characterized by
sizable CAPE appears likely to be maintained through this time
frame, and perhaps a bit beyond.
