DISCUSSION...

Persistence continues to rule today, as diurnally driven
thunderstorms have already begun to develop across higher
elevations from the Davis Mountains north to the Guadalupe
Mountains. Isolated to scattered storms will continue into this
evening, mainly across the higher terrain and the adjacent plains.
Similar to the past few days, severe weather is not anticipated,
however, locally heavy rainfall, gusty winds, and lightning will
be possible with any storm that develops. The locally heavy
rainfall could lead to flooding concerns, particularly for
locations that have received appreciable rainfall over the past
several days. Friday will be similar to today, with highs a few
degrees above normal, and isolated to scattered storms mainly
along and west of the Pecos River. Easterly flow aloft will
continue into this weekend as the upper high shifts eastward, and
while 850mb temperatures will increase, heights will fall in
response to a disturbance that will progress westward across
Texas. Thus, temperatures will remain near to just above normal,
with rain chances expanding eastward from the higher terrain
across the Trans Pecos and Permian Basin. Isolated to scattered
storms look to be possible for most of the area both Saturday and
Sunday.

An upper low dropping out of Canada through the Great Lakes late
in the weekend will amplify the pattern, with ridging
reasserting itself across the western CONUS early next week. The
ridge will then build eastward over the region, which will yield
continued near normal to just above normal temperatures next week,
and storm chances once again shifting west to the higher terrain.
