Panhandles
Concerning…Severe potential…Watch possible
Valid 162049Z – 162245Z
Probability of Watch Issuance…40 percent
SUMMARY…Some increase in the severe-wind and isolated hail threat
is possible through late afternoon into early evening.
DISCUSSION…Convection developing near the higher terrain of
south-central CO into northeast NM has gradually intensified this
afternoon, with a recent measured gust of 51 kt at Colorado Springs.
Farther east, storms are beginning to develop across parts of
southeast CO into the Raton Mesa vicinity. Low-level moisture is
generally rather modest across the region, but strong heating has
resulted in MLCAPE increasing to 500-1000 J/kg, with some further
increase possible into late afternoon. Modest northwesterly midlevel
flow along the periphery of an upper ridge over the southern Rockies
is supporting effective shear of 25-35 kt, which may support
occasional storm organization.
Initial discrete storms will continue to pose a threat of isolated
severe gusts and possibly some hail. With time, increasingly
prominent outflow within the initially hot and well-mixed
environment will support development of one or more loosely
organized clusters, which would move southeastward with some
increase in the severe-wind threat into parts of the
central/southern High Plains. Watch issuance is possible over parts
of the region, if a more organized severe threat appears imminent.
