This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...Today and Tonight...

.Thunderstorms...
There is a Slight Risk of severe thunderstorms this afternoon
and tonight across parts Oklahoma and western north Texas.

.Location...
The Slight Risk area is generally along and west of a line from
Enid to Stillwater to Holdenville and Durant. The Slight Risk
area also covers most of western north Texas. There is a Marginal
Risk that covers the rest of Oklahoma.

.Timing...
The most likely time for severe storms will be from 3 pm through
about midnight.

.Impacts...
Damaging wind gusts of 60 to 70 mph and hail up to the size of
golf balls will be the main hazards.

Some of the storms today will produce locally heavy rainfall which
may result in some flooding.

.Discussion...
Scattered showers thunderstorms moving across northern and central
Oklahoma this morning are expected to gradually weaken through
9 to 10 am. A few storms may produce hail near the size of
quarters and gusty winds near 45 mph.

By mid afternoon, heating will result in moderate to strong
instability across a large part of Oklahoma and western north
Texas. The first thunderstorms are expected to develop across
northern and perhaps central Oklahoma by mid afternoon. Other
storms may develop near a dryline in the eastern Texas Panhandle.
Large hail and damaging winds will be likely with the storms that
form in the afternoon and early evening.

By early to mid evening, thunderstorms may organize into a
thunderstorms complex and move southward across central and
southern Oklahoma and western north Texas.  As this occurs, the
main hazard will be damaging winds.  During the overnight hours,
most of the thunderstorms are expected to be confined to the
southern half of Oklahoma and western north Texas.

Storm spotter groups and emergency management personnel should
prepare for severe weather operations.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday...

.Heat...
Triple digit heat is expected across the western third of Oklahoma
and western north Texas this weekend and again by the middle
of next week.

.Thunderstorms...
A few thunderstorms could move into western Oklahoma during the
evening hours Sunday, Monday, and Tuesday. Severe thunderstorms
are unlikely during this period.
