This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...Today and Tonight.

SEVERE THUNDERSTORM.
RISK...Limited.
AREA...Northwest of Interstate 44 and West of Highway 75.
ONSET...After Midnight.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Late Morning.

DISCUSSION...
Southerly winds gusting to 30 mph will develop by late morning,
diminishing during the early evening hours.

Thunderstorms are expected to develop across parts of Kansas near
a southward moving cold front during the evening and overnight
hours. These thunderstorms could affect parts of northeast
Oklahoma, mainly northwest of Interstate 44 and west of Highway
75, after midnight. Although these thunderstorms are likely to
diminish toward sunrise, a Limited threat of large hail and
damaging winds will exist.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
THURSDAY AND FRIDAY...Severe Thundertorm Potential...Heavy Rain Potential.
SATURDAY THROUGH TUESDAY...No Hazards.

EXTENDED DISCUSSION...
Thunderstorms, likely below severe limits, may be ongoing
Thursday morning across parts of northeast Oklahoma, pushing
southward during the morning hours. Additional thunderstorms may
develop as early as mid to late afternoon Thursday near a frontal
boundary, but more widespread thunderstorm potential should hold
off until Thursday night and Friday. A few of the Thursday
afternoon and Thursday night thunderstorms could have large hail
and damaging wind potential.

A greater severe thunderstorm potential will exist Friday
afternoon and into Friday night as an upper level storm system
moves through the region. A strong cap is expected to be in place
across southeast Oklahoma and into west central Arkansas, to the
south of a warm front and to the east of a cold front. If
discrete storms are able to develop during the afternoon and early
evening, very large hail, damaging winds, and a limited tornado
threat will exist. To the north of the warm front, the strongest
storms could produce large hail. More linear storm modes are
likely during the evening as the cold front pushes through the
area. All thunderstorm activity should be east of the area by
Saturday morning, although a small chance of showers will continue
to linger.

In addition to any severe thunderstorm threats, heavy rain and
flooding potential will begin to increase late Thursday night,
especially across parts of northeast Oklahoma and far northwest
Arkansas, to the north of the front. This potential will continue
through much of Friday and Friday night, with widespread storm
total amounts from 3 to 6 inches, and locally to 9 inches,
expected north of Interstate 40. Amounts this high could lead to
both flash flooding and river flooding.
