ZCZC SPCSWOMCD ALL ACUS11 KWNS 192223 SPC MCD 192223 NMZ000-200030- Mesoscale Discussion 2150 NWS Storm Prediction Center Norman OK 0523 PM CDT Sat Oct 19 2024 Areas affected...East-central New Mexico Concerning...Severe potential...Watch unlikely Valid 192223Z - 200030Z Probability of Watch Issuance...20 percent SUMMARY...The severe threat will likely be maximized across east-central New Mexico over the next 2-3 hours as supercells continue to mature within a supportive environment. Watch issuance is not expected given the relatively limited spatial/temporal extent of the threat. DISCUSSION...Over the past hour, several supercells across east-central NM have become much more intense and well-organized, as evident by robust hail signatures in MRMS data and three-body scatter spikes evident in KFDX imagery. In particular, two cells between the Fort Sumner and Roswell areas are currently moving across the most favorable thermodynamic environment, which is characterized by MLCAPE values between 1000-1500 J/kg per recent RAP mesoanalysis estimates. With 40-50 knots of effective bulk shear already in place across the warm sector, these two storms will likely remain discrete/semi-discrete supercells for the next couple of hours. Increasing low-level helicity after 00 UTC associated with a strengthening nocturnal jet may support some increase in tornado potential, but this may be conditional on whether storms remain in the viable surface-based warm sector, which is currently limited in northern extent by a residual stationary boundary north of the I-40 corridor. Regardless, these cells will likely pose a severe hail (possibly up to 1.75 inches in diameter) and wind threat through at least 00-01 UTC. ..Moore/Guyer.. 10/19/2024 ...Please see www.spc.noaa.gov for graphic product...
