....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Isolated non-severe thunderstorms will be possible this afternoon
and evening across parts of west Texas and southeast New Mexico.

....DISCUSSION...
An upper-level trough will move across the Great Lakes region and
Ohio Valley today, as a shortwave ridge moves into the southern and
central High Plains. Further to the west, an upper-level trough will
move into southern California. Southwesterly mid-level flow will be
located from the Desert Southwest into the southern and central
Rockies. In response, a 30 to 40 knot low-level jet is forecast to
develop today in the southern High Plains. Isolated thunderstorm
development will be possible this afternoon and evening in west
Texas and southeast New Mexico, along the western and northern edge
of the low-level jet, where lift will be maximized. This convection
is not expected to become severe. Elsewhere across the continental
U.S., thunderstorms are not expected today and tonight.
