Valid 250113Z - 250315Z The severe weather threat for Severe Thunderstorm Watch 310 continues. SUMMARY...Strong/severe storms continue over parts of eastern Colorado and adjacent/far western Kansas. As risk expands/spreads eastward with time this evening, an eventual/new WW extending into central Kansas appears likely. DISCUSSION...Latest radar loop shows storms congealing into a fairly intense cluster over the Cheyenne/Kit Carson County vicinity in east-central Colorado, with some initial/subtle hints of possible mesolow development. Farther southeast, a somewhat loosely organized band of storms is indicated, with an eventual merging of these two convective areas expected with time. As the eastern Colorado/western Kansas convection evolves, eastward advance of the storms will eventually result in severe risk spreading across eastern portions of WW 310, into central Kansas. This would likely warrant eventual/new WW issuance, as a developing low-level jet supports convective continuation. Meanwhile though, a small but rather vigorous cluster of updrafts has developed just west of Pratt, KS, east of the southeastern corner of WW 310. We will continue to monitor evolution of this convective cluster, as any additional increase in convection could force earlier consideration for a new WW east of WW 310 than may otherwise have been necessary. ..Goss.. 06/25/2021 ...Please see www.spc.noaa.gov for graphic product...
