MD 1190 CONCERNING SEVERE POTENTIAL…WATCH LIKELY FOR WESTERN/CENTRAL KANSAS AND FAR NORTHERN OKLAHOMA
Mesoscale Discussion 1190
NWS Storm Prediction Center Norman OK
0837 PM CDT Thu Jun 29 2017
Areas affected...western/central Kansas and far northern Oklahoma
Concerning...Severe potential...Watch likely
Valid 300137Z - 300300Z
Probability of Watch Issuance...95 percent
SUMMARY...Thunderstorms over western Kansas are expected to continue
moving eastward and eventually organize into an MCS. The
severe-weather hazards will include large hail and damaging winds,
transitioning to primarily a wind threat after upscale growth
occurs. A severe thunderstorm watch is likely needed.
DISCUSSION...Severe thunderstorms moving eastward out of western
Kansas will encounter a more unstable environment across central
Kansas, characterized by MUCAPE values around 2500 J/kg and
deep-layer shear around 40 knots. As the southerly low-level jet
increases this evening across western Oklahoma and the eastern Texas
Panhandle, this should support ongoing storms and new initiation
across southwestern Kansas. Storms will initially pose a risk of
large hail and damaging winds. As upscale growth occurs throughout
the evening, damaging winds will become the primary severe-weather
threat.
