.PREV DISCUSSION... /issued 319 AM CDT Fri Aug 18 2017/

DISCUSSION...
Upper ridge extending from the Atlantic across TX to NM will become
centered over TX Saturday.  Out west an upper trough will set up
along the CA coast.  This trough will not be strong enough to
dislodge the ridge and will remain near its location well into next
week.  Looking ahead into next weekend the ridge should become more
established over the 4 corners region and remain over TX and NM.
Until the ridge is dislodged look for little change in the daily
pattern.

No fronts seen moving through the area for the coming week.  Will
stay on the warm side of guidance with more of a persistence
forecast.  Long range guidance keeps temps nearly constant with
widespread highs in the mid to upper 90s for the area.  Morning
lows will remain elevated due to the high dewpts well into the 60s.

Expect storms again today as have good low level moisture... daytime
heating and old outflow boundaries to form on.  The highest pops
will be west over the higher elevations.  Although increasing
heights may make storm formation less favorable... have had
thunderstorms across the Permian Basin every afternoon this week so
will go ahead add isolated pops today.  Locally heavy rain will be
possible with any of these storms.  Mountains looked favored
Saturday and Sunday too.  In the extended wIll have to watch a low
coming off the Gulf and into the area late next week... could be a
wx producer.
