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

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

There is a Moderate Risk of severe thunderstorms across parts of
Oklahoma, surrounded by Slight and Enhanced Risk areas that cover
additional parts of Oklahoma and western north Texas.

The Moderate Risk area is west of a line from Waurika to Duncan to
El Reno to Guthrie, and south of a line from Guthrie to Stroud.
This includes the Oklahoma City metropolitan area, Pauls Valley,
Ardmore, Seminole, Ada, Atoka and Durant.

To the west of the Moderate Risk area, there is a Slight and
Enhanced Risk of severe weather across northern and western
Oklahoma, to the east of a line from Laverne to Clinton to Lawton
to Clay County Texas.

Timing... 4 pm through 9 pm.

Large hail up to tennis ball size will be the main hazard.
Damaging winds and tornadoes will also be possible.

Morning data suggests an increased potential of severe weather
late this afternoon and this evening. Although low-level moisture
is low this morning, higher humidity is moving quickly north
through Texas and will move into Oklahoma this morning and
afternoon. This moisture will allow the atmosphere to become very
unstable this afternoon.

Scattered storms are expected to develop late this afternoon
across western sections of north Texas and western Oklahoma and
become severe as they move east-northeast. The atmospheric wind
shear will support supercell thunderstorms with the associated
risk of large hail, damaging winds, and the potential of isolated
tornadoes. The highest chances of severe weather will be across
central, south central and southeast Oklahoma where instability
will be the highest. Storms are expected to move out of the area
around or just after midnight.


Storm spotter groups and emergency management personnel across
central, western, and southern Oklahoma and portions of north
Texas should prepare for severe weather operations from about
4 pm through midnight.

.Fire weather...
Fire Danger will be very high across southwestern Oklahoma and
western north Texas as dry air moves in behind a dryline. A Red
Flag Warning is in effect through early evening for this area.

Patches of fog will reduce visibilities in parts of northern and
southeast Oklahoma early this morning.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

There is a slight risk of severe thunderstorms again on Tuesday
and Wednesday. There is also a chance of thunderstorms on Thursday
and Saturday.

.Heavy rain...
Heavy rain is possible on Tuesday, and likely on Wednesday.
