...Enhanced Severe Thunderstorm Threat and Locally Heavy Rain
Saturday Evening into Saturday Night...

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 expected at this time.

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

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

EXTENDED DISCUSSION...
Dry weather and unseasonably warm temperatures will continue into
Friday ahead of a strong storm system expected to impact the
region Saturday evening into Saturday night. Increasing moisture
ahead of the associated cold front may 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 the 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 sweeps
through southeast Oklahoma and northwest Arkansas through early
Sunday morning. A few tornadoes will also be possible as strong
low level wind fields develop Saturday evening into the overnight
hours. In addition to the severe weather threat, 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.
