Day 1 Convective Outlook

Valid 100100Z - 101200Z

....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE SOUTHERN HIGH PLAINS...

....SUMMARY...
Isolated severe thunderstorm gusts and large hail remain possible
across portions of the southern High Plains this evening.

....01z Update...

Early-evening satellite imagery suggests southern-stream short-wave
trough has advanced into central OK, extending southwest into west
TX. The majority of deep convection, with lightning, is occurring
behind the trough within northwesterly flow where strong surface
heating contributed to steep lapse rate environment. 00z sounding
from MAF exhibited minimal inhibition with MLCAPE around 1000 J/kg.
Additionally, while deep-layer shear is not particularly strong,
profiles favor storm organization. Latest radar supports this with a
few supercells lingering across the TX South Plains. Some of this
activity has produced hail around 1 inch along with a few severe
wind gusts. Isolated supercells should propagate southeast this
evening with an attendant risk for some hail/gusty winds.
