.DISCUSSION...
Cold front currently located near the OK/KS state line this morning will
continue a slow push southward today.  South of front, another very warm
afternoon expected with high temperatures in the mid/upper 80s along
and south of the I-40 corridor. Scattered showers/isolated thunderstorms
will be possible north of back door front into Wednesday as boundary
stalls over southeast Oklahoma then becomes diffuse/lifts north on Thursday.

Models remain in good agreement with moving strong upper level storm system
out of the southern Rockies and into the Central Plains Friday.  A line of
showers/thunderstorms will develop east of dry line Friday morning, sweeping
east through the area Friday afternoon in low level jet axis.  Although
instability will be somewhat marginal, at least a limited severe threat is
expected, including locally heavy rainfall. Additional thunderstorms will
be possible in association with vertically stacked low Friday night into
Saturday morning before system lifts northeast. These storms would pose more
of a hail threat given the steep mid level lapse rates/cold temperatures aloft.

Active weather pattern will continue as another upper wave approaches Sunday
afternoon into Sunday night with an additional round of showers/thunderstorms,
including the potential for a more significant severe weather event.

marginally severe hail this afternoon and tonight.

Additionally...fire danger will continue across most of the area
