MD 2201 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR CENTRAL NEW MEXICO TO FAR WEST TEXAS
Mesoscale Discussion 2201
NWS Storm Prediction Center Norman OK
0453 PM CDT Tue Sep 26 2023
Areas affected…Central New Mexico to far west Texas
Concerning…Severe potential…Watch unlikely
Valid 262153Z – 270000Z
Probability of Watch Issuance…5 percent
SUMMARY…Isolated to scattered thunderstorms developing across
central New Mexico to far west Texas will pose an isolated large
hail and severe wind risk through the early evening hours. Watch
issuance is not expected.
DISCUSSION…Thunderstorm development has been well underway across
NM to far west TX, but recent GOES IR imagery and lightning trends
have shown an uptick in intensity in a few cells. While not
high-caliber by most measures, the environment across the region
remains favorable for organized convection with 1000-1500 J/kg
MLCAPE and effective shear values near 20 knots. This may support a
few organized cells capable of posing a large hail risk. Dewpoint
depressions across the region on the order of 40-50 F indicate that
the boundary layer is fairly well mixed, and this is supported by
0-3 km lapse rates around 8-9 C/km per latest mesoanalysis
estimates. This low-level thermodynamic environment, combined with
PWAT values below 1 inch, is conducive for downbursts and perhaps
outrunning outflows that may lead to thunderstorm clustering. Both
of these scenarios would pose a risk for strong to severe gusts
through the early evening hours prior to sunset and on the onset of
nocturnal cooling. However, given the overall marginal convective
environment, watch issuance is not expected.
