DISCUSSION...
Storms are starting to fire up in New Mexico this afternoon. Hi-
res models indicate there is a chance for the storms to make it to
the western Panhandles late this afternoon. The TTU WRF has storms
initiating in the southwestern TX Panhandle. Soundings indicate
there is a good amount of instability and low level directional
shear for storms to strengthen if they can get strong enough.
There are several boundaries left over across the Panhandles from
the storms last night as well as a dry line in the western
Panhandles. Storms will likely need to adhere to one of these to
become strong. In addition, there is a weak upper level shortwave
that should cross over the area this evening which could aid in
storm strengthening. If we see any storms, it will likely be just
a few isolated ones that could become severe.

As moisture continues to get pumped into the eastern Panhandles,
patchy fog development will again be likely tonight. After the sun
burns it off, Tuesday through Thursday will see temps warm into
the 80s and even some 90s due to downsloping and abundant
sunshine. The next system continues to look on track for bringing
precip back to the area Thursday night through Saturday. Long
range models are becoming more in agreement with cutting off
precip early on Saturday and dryslotting the area. At this time,
thunderstorms look to remain below severe levels. The remainder of
the weekend looks to be dry as upper level ridging takes hold.
