it appears that the Last Chance for rain before Sunday has ended
across central and western Oklahoma and western North Texas. An
outflow boundary from the earlier convection moved west across
central Oklahoma earlier...but has become very diffuse and will
continue to dissipate overnight. A fairly strong temperature/dew
point boundary coincident with the outflow boundary will likewise
gradually fade.

This update includes minor adjustments to hourly forecasts of
temperature and humidity...and rain chances were removed earlier.

Aviation...
VFR conditions to prevail this taf period. Isolated storms will
be possible through around 00z...but will remain east of
terminals. Pronounced outflow boundary from earlier storms has
resulted in easterly wind shift from kpnc southward to kokc/koun. This
boundary will essentially wash out as srly flow resumes overnight.
Breezy and gusty south winds to resume at all terminals around 15z
Friday.

Discussion...
a small area of convection over Payne/Lincoln counties should
continue into northeast/east central Oklahoma this afternoon.
Meanwhile... much drier air is located across part of North Texas/southern
Oklahoma this afternoon. Nearcast model captured this well earlier
this morning. Weak convergence and heating may allow an isolated
storm to form over central Oklahoma between 4 and 7 PM...otherwise
probability of precipitation for tonight will be at or below 10 percent.

An upper low over northern Mexico and tropical moisture in south
Texas...will remain south of the forecast area. A ridge...centered to our
west...will build eastward Friday into Sunday. This will bring a
period of very hot and dry weather with most locations reaching
triple digits.

A cold front is forecast to move across Oklahoma and North Texas
late Sunday into Monday...at least an initial wind shift. Better
cold air advection will arrive Monday night into Tuesday. Rain and storm chances
with the front will be highest Monday night into Tuesday and again
Wednesday into Thursday as a wave approaches.
