Mesoscale Discussion 0695
NWS Storm Prediction Center Norman OK
0802 PM CDT Sat May 23 2020
Areas affected...Southwest and West-central Kansas
Concerning...Severe potential...Watch unlikely
Valid 240102Z - 240330Z
Probability of Watch Issuance...20 percent
SUMMARY...An isolated severe threat should continue across parts of
southwest and west-central Kansas over the next couple of hours.
Large hail and wind damage would be the primary threats. Weather
watch is not expected but the situation will continue to be
monitored.
DISCUSSION...Latest surface analysis shows a 997 mb low in southeast
Colorado. A dryline is present from the Texas Panhandle into
southwest Kansas with a moist airmass in place to the east of the
dryline. Surface dewpoints in the lower to mid 60s F are
contributing to moderate instability. Thunderstorms are developing
along the western edge of moderate instability to the southwest of
Dodge City. The WSR-88D VWP at Dodge City shows 0-6 km shear of 40
to 45 kt with some directional shear in the low to mid-levels. 700
to 500 mb lapse rates are very steep approaching 9.0 C/km. For this
reason, left-moving supercells with large hail will continue to be
possible over the next couple of hours. Again, the severe threat
should be too isolated to warrant weather watch issuance.
