...Widespread thunderstorms expected Saturday evening into Saturday
   night with severe weather and heavy rainfall...

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

.DAY ONE...Today and Tonight.

No hazardous weather is anticipated through tonight.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...Thunderstorm and High Wind Potential.
SATURDAY...Severe Thunderstorm...High Wind Potential and Heavy
Rain Potential.
SUNDAY THROUGH WEDNESDAY...No Hazards.

EXTENDED DISCUSSION...
Unseasonably warm and dry weather is expected today and Friday
ahead of a strong storm system which is expected to impact the
region Saturday evening into Saturday night. Increasing moisture
ahead of the front could result in scattered showers and a few
thunderstorms Friday night into early Saturday. Severe weather
chances will be low with these storms.

Showers and thunderstorms will develop along a cold front and
move into northeast Oklahoma early Saturday evening. Severe
weather is likely with the potential for large hail and damaging
winds with the initial thunderstorm development. The storms will
become more linear in nature, transitioning mainly to a wind
threat by late evening into the overnight hours as the line of
storms sweep through southeast Oklahoma and northwest Arkansas by
Sunday morning. A few tornadoes will also be possible as strong
low level wind fields develop Saturday evening into the overnight
hours. In addition, heavy rain is likely across much of the area
with widespread 2 to 3 inch rainfall amounts. Locally higher
totals of 4 to 5 inches will be possible in some areas that could
lead to flash flooding or river flooding.

Storms are expected to sweep east of the region Sunday morning with
cooler and dry conditions behind the front into the early part of
next week.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Persons attending outdoor events Saturday evening should prepare
for thunderstorms with the potential for severe weather. The
overall tornado threat will continue to be assessed as additional
data becomes available as the event approaches.
