Area Forecast Discussion
National Weather Service Norman OK
233 PM CDT SAT JUL 9 2016

.DISCUSSION...
Determining rain chances over the next several days is the
challenge of the day. Summer heat will continue.

Before midnight tonight, believe a few thunderstorms will remain
across the area, though storm coverage should be rather low due to
weak subsidence behind a mid/upper trough that is over
southeastern Oklahoma. Generally only went 10-20% rain chances
this evening with higher chances 40-90% this afternoon near the
Red River east of Wichita Falls. Current complex of storms along
the Red River near and east of I-35 as of 230 PM will continue to
push south into north Texas. Believe a few additional storms may
form on lingering outflow boundaries mainly southeast of I-44
where deepest moisture exists with precipitable water values
1.7-2". Any storm should be slow moving which can dump a few
inches of rainfall in small areas. Severe potential is low, though
cannot rule out damaging winds up to 60 mph if storms occur as
daytime heating supports DCAPE values of 1000-1800 J/kg.

After midnight tonight, a few storms may linger closer to the
departing mid/upper trough and where moisture convergence may be
stronger in southeastern Oklahoma. A complex or two of storms may
occur across the High Plains and get into far western Oklahoma and
far western north Texas, though it appears the greater chances for
this to occur will be over the Panhandles.

Sunday looks to be another hot and humid day with even lower rain
chances than today as the cap strengthens. Head indices may
approach 105 degrees in some areas. Did not issue a Heat Advisory
as not sure how high surface dewpoints will be. Cannot completely
rule out a stray afternoon and evening storm, but chances appear
to be too low to mention, generally below 15%.

Sunday night into Monday, there is a slight signal that storms
over the High Plains may make into the area, but confidence is
very low. Hot and humid conditions will continue. Surface winds
will increase on Monday.

Monday night through Friday, no signficant changes in the weather
pattern are expected with continued hot weather along with low
chances for showers and storms. A weak front may approach Kansas
or northern Oklahoma during this time frame which could serve as a
focus for higher rain chances. Chances of widespread rainfall
remain low during this time frame.
