MD 0294 CONCERNING SEVERE THUNDERSTORM WATCH 53… FOR SOUTHERN OKLAHOMA
Mesoscale Discussion 0294

Areas affected...Southern Oklahoma
Concerning...Severe Thunderstorm Watch 53...
Valid 212146Z - 212315Z
The severe weather threat for Severe Thunderstorm Watch 53
continues.
SUMMARY...Strong/severe thunderstorms will spread/develop northeast
into southern Oklahoma over the next few hours.
DISCUSSION...Mid-level speed max over the Edwards Plateau is
ejecting toward southeast OK. This feature will encourage further
strengthening of the LLJ across northeast/eastern OK where values
will likely approach 70kt by early evening. Extensive convection
across OK is expected to maintain cooler boundary-layer conditions
north of a warm front that should advance slowly north ahead of the
primary surface low. Several long-lived supercells are currently
tracking northeast toward south-central OK where updrafts may become
elevated as they cross the warm front. Forecast soundings suggest
ample buoyancy exists across southern OK for robust elevated
convection capable of generating large hail, and perhaps isolated
severe wind gusts. There is some concern that areas east of I-35
over southern OK may need to be included in a severe thunderstorm
watch -- either new or extended -- to account for this activity
spreading/developing northeast.
