MD 1725 CONCERNING SEVERE THUNDERSTORM WATCH 502... FOR EASTERN KANSAS...WESTERN MISSOURI...AND FAR SOUTHERN IOWA
Mesoscale Discussion 1725 NWS Storm Prediction Center Norman OK 0538 PM CDT Sat Oct 21 2017 Areas affected...Eastern Kansas...western Missouri...and far southern Iowa Concerning...Severe Thunderstorm Watch 502... Valid 212238Z - 212345Z The severe weather threat for Severe Thunderstorm Watch 502 continues. SUMMARY...The risk of damaging wind gusts and isolated hail continues along and ahead of a squall line in western portions of WW 502. DISCUSSION...Storms have mostly congealed into linear segments along an outflow that extends from near STJ to TOP to just southeast of ICT. Several of these storms are mostly behind this outflow and slightly elevated atop a stable boundary layer - especially across south-central Kansas. Hail will be the primary threat with this activity, while damaging wind gusts will be the primary threat with convection along and ahead of the boundary - particularly with storms near and east of the Topeka area that have exhibited bowing segments. An additional risk for surface based activity will occur with pre-frontal convection migrating northeastward from north-central Oklahoma. West of this line, the severe threat is diminishing as thermodynamic profiles stabilize behind the cold front. The severe thunderstorm watch may be cancelled early for areas behind the front. See attendant Watch Status messages for further guidance. ..Cook.. 10/21/2017 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...SGF...DMX...EAX...TSA...OAX...TOP...ICT...OUN...
