.PREV DISCUSSION... /issued 750 PM CDT Tue May 15 2018/

DISCUSSION...
Models indicate that thunderstorms moving across the western and
central TX panhandle will arrive into at least southwestern OK and
adjacent parts of northern TX late this evening. This is in
addition to the ongoing isolated storms now over this part of
northern TX. The moist upslope flow in the boundary layer and
remaining insolation and a weak mid-level wave are expected to
keep these storms going until midnight or beyond. A damaging wind
threat is possible in southwestern OK and adjacent parts of
northern TX. Very heavy rainfall is likely in some areas. POPS
have been increased in these areas.
