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

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

.Fire Weather...
Critical to extreme fire weather conditions will develop this
afternoon with warm, dry and breezy weather. The most significant
fire weather conditions will be across western north Texas and
western Oklahoma where humidity will fall to between 10 and 20
percent this afternoon.

.Thunderstorms...
There is a slight risk of severe thunderstorms across southeastern
Oklahoma.

Location...
The slight risk includes Atoka and Bryan Counties. There is a
marginal risk of severe thunderstorms west of the slight risk and
east of a line from Wewoka to Ada to Madill.

Timing...
Between 2 PM and 7 PM.

Impacts...
Thunderstorm wind gusts of 60-70 mph will be possible, along with
hail up to quarter size. An isolated tornado is possible in the
slight risk area.

Discussion...
Scattered showers and thunderstorms will develop across
southeastern Oklahoma this afternoon. The atmosphere will become
somewhat unstable in southeastern Oklahoma this afternoon and
evening and may be enough to support an isolated severe
thunderstorm this afternoon and early evening. Although
instability will not be very high, strong low-level wind shear
could support a low tornado threat across southeast Oklahoma. The
severe weather risk will diminish early this evening as the storms
move east of Atoka and Bryan Counties.

.SPOTTER AND EMERGENCY MANAGEMENT STATEMENT...

Storm spotter groups and emergency management personnel across
southeastern Oklahoma should prepare for severe weather
operations from around 2 PM to 7 PM..

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

.Fire Weather...
Critical fire weather conditions will develop again Monday
afternoon across western north Texas due to gusty northwest winds
and low humidity, despite cooler temperatures. Near-critical
conditions are expected over much of Oklahoma.

Elevated fire weather conditions are expected again on Tuesday,
Thursday and Friday afternoon as Oklahoma and Texas remain in a
warm and dry pattern.

.Thunderstorms...
Thunderstorms will be possible Friday and Friday night.
