...SEVERE STORMS POSSIBLE TONIGHT...

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...Eastern Oklahoma and Western Arkansas.
	ONSET...Mainly after Midnight.

FLASH FLOOD.
	RISK...Limited.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Mainly after Midnight.

HEAVY RAIN.
	RISK...Limited.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Mainly after Midnight.

DISCUSSION...
The threat of thunderstorms will increase over Eastern Oklahoma
and Northwest Arkansas through tonight ahead of a cold front
forecast to move into the region late tonight. A few strong to
marginally severe storms are possible late this evening and
overnight tonight. Hail to the size of quarters look to be the
main threat. After midnight tonight into very early Saturday
morning, surface-based instability may develop into Southeast
Oklahoma, which would result in a threat of larger hail and
increase the damaging wind threat.

Locally heavy rainfall will be possible within the strong showers
and thunderstorms through tonight with rainfall amounts up to
one inch in some areas, with isolated amounts up to 2 inches
possible. This could create localized areas of flash flooding
conditions tonight.

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

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
SATURDAY...Thunderstorm Potential...Very High Fire Weather Potential...High Wind Potential.
SUNDAY...High Wind Potential.
MONDAY through THURSDAY...No Hazards.

EXTENDED DISCUSSION...
Showers along with isolated to scattered thunderstorms are
expected to be ongoing early Saturday along and ahead of a cold
front pushing through the region. The greater thunderstorm
potential is forecast over far Southeast Oklahoma into Western
Arkansas through mid morning.

Precipitation should taper off from west to east behind the
front...with clearing skies and gusty west to southwesterly winds
in the 25 to 40 mph range. The stronger gusts look to be over
Northeast Oklahoma. These winds combined with much drier air
behind the front could increase fire weather concerns for parts of
Eastern Oklahoma Saturday afternoon. Gusty winds and limited fire
weather conditions are forecast to continue into Sunday before an
upper level low pressure system finally exits the Plains.
