DISCUSSION...
Forecast remains largely unchanged.  Chances for thunderstorms
retained Friday night through Saturday night.

Warmup continues today, with deep dry southwest flow allowing max
temperatures to reach the 80s area-wide.  A cold front makes an
intrusion into northern sections on Friday, keeping those areas a
bit cooler with highs in the upper 70s to around 80.  The front
is expected to lift north of the area Friday evening.

Moderately  strong southwest flow in lower levels will replenish
moisture Friday night.  An upper-level disturbance in southwest
flow aloft may lead to thunderstorm development late Friday night
across mainly the northeast one-quarter of the Combined Texas and
Oklahoma Panhandles.  Limiting factors will be an expected cap
and lack of low-level convergence.

Thunderstorm chances continue Saturday in the northeast, where
low-level moisture will remain in place ahead of a dryline-like
feature advancing into western sections.

Best opportunity for thunderstorms continues to be Saturday
night, when the strong cold front sweeps through the area.  Pops
Saturday night confined to the eastern half of the Panhandles,
owing to aforementioned dry setup in the west.  A few strong to
marginally severe thunderstorms may develop Saturday evening in
the northeast.  Expected rapid storm motions may lead to an
enhanced wind threat.

Much cooler conditions expected on Sunday in wake of strong cold
front, with highs about 10 degrees Fahrenheit below climo.  Much
drier air in post-frontal airmass allows Sunday night low
temperatures to fall into the 30s over most of the area.  Modest
warming trend follows with highs returning to near-normal by
Tuesday.  No pops Sunday through Wednesday due to dry post-
frontal airmass.
