Mesoscale Discussion 0616
NWS Storm Prediction Center Norman OK
0614 PM CDT Sat May 16 2020
Areas affected...portions of southeast CO...northeast NM and the far
western TX Panhandle
Concerning...Severe potential...Watch unlikely
Valid 162314Z - 170045Z
Probability of Watch Issuance...5 percent
SUMMARY...A strong to severe storm or two is possible through the
evening hours. Gusty winds and possibly large hail may accompany
these storms. Given the isolated nature of the threat, a watch is
not expected.
DISCUSSION...Showers are developing early this evening in weak
upslope flow near Raton. Surface dewpoints remain poor, mainly in
the mid 40s F. However, temperatures have warmed into the mid 70s to
low 80s beneath steep midlevel lapse rates. This has resulted in
MLCAPE values as high as 500 J/kg. Veering winds with height, and
increasing midlevel northwesterly flow is responsible for a belt of
35-45 kt effective shear. This should be sufficient for the
development of an organized storm or two capable of large hail.
Inverted-v sub-cloud layer thermodynamic profiles with steep low
level lapse rates will foster gusty wind potential with these
storms, in addition to hail. Convection should weaken as it tracks
south/southeast toward the OK/TX Panhandle vicinity later this
evening as nocturnal cooling results in increasing inhibition and
midlevel lapse rates and instability weaken.
