MD 2218 CONCERNING SEVERE POTENTIAL…SEVERE THUNDERSTORM WATCH LIKELY FOR FAR WEST TEXAS INTO THE PERMIAN BASIN
Mesoscale Discussion 2218
NWS Storm Prediction Center Norman OK
0159 PM CDT Tue Oct 03 2023
Areas affected…Far West Texas into the Permian Basin
Concerning…Severe potential…Severe Thunderstorm Watch likely
Valid 031859Z – 032030Z
Probability of Watch Issuance…80 percent
SUMMARY…A few supercells are expected to develop this afternoon
across Far West Texas and move into the Permian Basin.
DISCUSSION…Cumulus have started to build over the Davis mountains
as temperatures have risen into the upper 80s to near 90 with
dewpoints around 60 F. This has yielded around 1500 to 2000 J/kg
MLCAPE. In addition, mid level flow is increasing across the region
with 8km flow in excess of 50 knots according to the RAP. Long,
relatively straight hodographs will support splitting supercells. In
fact, some forecast hodographs actually favor left movers which may
help to sustain them through the evening. Therefore, large hail will
be the primary threat, but some severe wind gusts may be possible in
the early stages where dewpoint depressions at or above 30F are
present, and also later this evening if supercells cluster and
result in a shorter-duration severe wind gust threat. A severe
thunderstorm watch will likely be needed by later this afternoon.
