Concerning...Severe Thunderstorm Watch 369...371...

Valid 150224Z - 150430Z

The severe weather threat for Severe Thunderstorm Watch 369, 371
continues.

SUMMARY...Severe threat is increasing across the south-central High
Plains.

DISCUSSION...Two separate linear MCSs, each about 75 miles long,
have evolved over the south-central High Plains this evening. This
activity initially struggled a bit, but each MCS appears to be
ingesting more buoyant air, with storm-top venting much more robust
over the last hour. Measured severe wind gusts have been noted with
the southern-most squall line, and severe gusts are also likely
occurring across southeastern CO as well. Over the next few hours,
LLJ will increase markedly over western OK which should encourage
eastward propagation north of the synoptic front. Damaging winds
remain the primary threat.
