Areas affected...Central and Eastern NM...Western TX and TX
Panhandle
Concerning...Heavy rainfall...Flash flooding possible
Valid 260215Z - 260815Z
SUMMARY...Locally expanding clusters of heavy showers and
thunderstorms will maintain a threat for flash flooding over the
next several hours.
DISCUSSION...The latest GOES-W IR/WV satellite imagery suite shows
some cooling convective tops across areas of central and eastern
NM and parts of far western TX as a deep layer trough and
associated closed low ejects gradually eastward across the region.
Stronger mid/upper-level forcing/ascent overspreading the region
will be interacting with a rather unstable airmass pooled across
especially south-central/southeast NM and far western TX in
conjunction with strong 850/700 mb moisture flux that continues to
surge north across the southern High Plains. Early evening MLCAPE
values of 1500 to 2000+ J/kg are in place which combined with 30
to 40 kts of effective bulk shear and the height falls should help
support some cell-organization over the next few hours, with some
additional expansion of convective activity expected this evening.
The instability and moisture transport (850/700 mb moisture flux
anomalies of +2 to +4 sigma) will support areas of high rainfall
rates, and the multi-model hires CAMs support some 1 to 2
inch/hour rainfall rates with the stronger and more focused
thunderstorms. Some some spotty additional storm total amounts of
2 to 3 inches is not out of the question tonight. The area of
greatest concern for these heavier totals will tend to be across
areas of east-central NM and northeastward into the TX Panhandle
where some cell-training concerns will exist.
These additional rains will maintain a threat for flash flooding
over the next several hours as a result. The normally dry washes
and burn scar locations will again be at greatest risk for impacts.
