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

.DAY ONE...This Evening and Tonight.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.
AREA...Northeastern Oklahoma and Northwestern Arkansas.
ONSET...Ongoing.

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

DISCUSSION...
Temperatures in the mid to upper 90s this afternoon, combined with
high humidity, has resulted in dangerously high heat index values
from 105 to near 110 degrees. A Heat Advisory is in effect into this
evening for much of the region. Conditions will improve toward
sunset.

Isolated to widely scattered thunderstorms have developed this
afternoon across southeastern Kansas and north-central Arkansas near
a weak frontal boundary. Some of this activity may develop into
northeastern Oklahoma and northwestern Arkansas early this evening.
Temperatures in the mid to upper 90s and dewpoint temperatures in the
mid to upper 70s have resulted in very unstable conditions. Despite
the very unstable air in place, wind shear over the region is weak.
The strongest storms that form will have the potential to produce
damaging wind, but given the weak wind shear, they will likely be
short-lived. Much of this activity will dissipate by mid evening.

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

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Thunderstorm Potential...Dangerous Heat Potential.
MONDAY and THURSDAY...Thunderstorm Potential.
FRIDAY...No Hazards.

EXTENDED DISCUSSION...
Isolated thunderstorms are likely again Sunday along with hot and
humid conditions. Afternoon heat index values around 105 degrees
will be common Sunday. Thunderstorm chances remain relatively low
through Monday before increasing Tuesday and Wednesday as a cold
front moves through the region.
