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

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Northeast Oklahoma.
	ONSET...After 5 PM.

DANGEROUS HEAT.
	RISK...Significant.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing.

	AREA AT GREATEST RISK...Northeast Oklahoma and West-Central Arkansas.

DISCUSSION...
Dangerous heat is the main concern across eastern Oklahoma
and western Arkansas this afternoon and into the early evening,
with heat index values topping out in the 105 to 115 degree range.
Conditions will improve after sunset this evening.

Isolated to scattered thunderstorms are expected to develop ahead
of a frontal boundary near the Kansas border later this afternoon
through the evening across northeast Oklahoma. The environment is
favorable for severe downburst winds from any sustained surface
based storms that can get going. Later on this evening, more
storms are expected to develop near the boundary across far
northeast Oklahoma into northwest Arkansas. While having less of a
severe threat, some tendency for the storms to train over the same
areas suggests that locally heavy rainfall will be possible.

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

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY thru SUNDAY...Thunderstorm Potential...Dangerous Heat Potential.
MONDAY...Thunderstorm Potential.
TUESDAY and WEDNESDAY...No Hazards.

EXTENDED DISCUSSION...
A secondary uptick in storm coverage and severe potential will be
Friday afternoon and evening as storms move into the region from
Kansas. Outside of any relief from rain/storms, dangerous heat
will persist thru the weekend. Relatively cooler temps are
expected next week as the upper ridge shifts west away from the
region.
