Mesoscale Discussion 0891

Areas affected...Parts of the TX South Plains/Permian Basin vicinity

Concerning...Severe potential...Watch possible=20

Valid 291929Z - 292130Z

Probability of Watch Issuance...60 percent

SUMMARY...Severe storms may develop by 4-5 PM CDT, with a threat of
hail and severe gusts. Watch issuance is possible.

DISCUSSION...Relatively strong heating is underway across parts of
west TX this afternoon, though some areas of mid/upper-level clouds
persist. Low-level south/southeasterly flow to the east of a weak
surface trough is maintaining sufficient low-level moisture for
moderate destabilization, with MLCAPE increasing to near/above 1500
J/kg across parts of the TX South Plains and Permian Basin.
Decreasing CINH and a subtle midlevel shortwave trough near the
TX/NM border will support scattered thunderstorm development by late
afternoon. An approaching mid/upper-level subtropical jet maximum
will lead to strengthening deep-layer shear (with effective shear of
40+ kt), and a few organized cells or clusters may evolve with time.

Isolated large hail will be possible, including conditional
potential for 2+ inch diameter hail if any sustained supercells
develop. Relatively deep mixing and steep low-level lapse rates will
encourage increasing outflow with time, with an attendant threat of
at least isolated severe gusts (potentially 75+ mph). Issuance of
one or more watches is possible later this afternoon in order to
address these threats.
