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

.DAY ONE...This evening and Tonight.

SEVERE THUNDERSTORM.
RISK...Limited.
Area...West central Arkansas.
Onset...before 8 PM.

DANGEROUS HEAT.
RISK...Significant.
AREA...All eastern Oklahoma and west central Arkansas.
ONSET...Ongoing...improving after sunset.

DISCUSSION...
A subtle surface boundary resides across west central
Arkansas where satellite indicates a narrow region of
enhanced cloud development.  The chance for thunderstorm
development is low and coverage would be isolated.
However conditions are strongly unstable and sufficient
wind shear is available such that any storm that does
form will have a chance to become severe.
The chance for storm development will decrease by mid
evening with the overnight storm activity expected
to remain northward across the central Plains.
Also, excessive heat will continue through the early
evening hours.  Heat index values of 105 degrees currently
will slowly diminish after sunset.

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

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...Thunderstorm Potential...Dangerous Heat Potential.
SUNDAY...Thunderstorm Potential.
MONDAY...No Hazards.
TUESDAY and WEDNESDAY...Thunderstorm Potential.
THURSDAY...No Hazards.

EXTENDED DISCUSSION...
Dangerous heat levels will again develop Saturday afternoon.
Heat index values of 105 to 110 degrees will be common.
Attention will then focus on a cold front passing late
Saturday night through Sunday bringing a chance of thunderstorms
and possibly severe weather.
Slightly cooler temperatures will prevail through early
next week, before a warming trend returns with thunderstorm
chances by mid week.
