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.
ONSET...After 4 am.

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

AREA AT GREATEST RISK...Northeastern Oklahoma.

DISCUSSION...
Temperatures in the mid 90s to near 103 degrees, combined with high
humidity, have resulted in dangerous heat across much of the region
with heat indices from 105 to 113 degrees. Excessive Heat Warnings
and Heat Advisories are in effect for all of eastern Oklahoma and
northwestern Arkansas through 8 pm, when conditions are expected to
gradually improve.

Thunderstorms developing across eastern Colorado this evening are
expected to move across Kansas this evening and tonight. Some of this
activity may reach northeastern Oklahoma late tonight. The chances of
severe weather with this activity is very low, but the stronger
activity may produce gusty outflow wind gusts.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential...Dangerous Heat Potential.
WEDNESDAY...Thunderstorm Potential...Heavy Rain Potential.
THURSDAY...Thunderstorm Potential.
FRIDAY...No Hazards.
SATURDAY and SUNDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Another hot day is expected on Tuesday before a frontal boundary
approaches portions of northeast Oklahoma Tuesday afternoon. A few
thunderstorms could develop along this boundary. Modest instability
could lead to a few strong to severe storms, with damaging wind gusts
the primary threat. The mid to upper level high pressure ridge
shifts back west by Wednesday and cooler temperatures will follow the
frontal boundary, along with continued thunderstorm chances.
Northwest flow aloft stays over the Plains through the weekend with
near to below average temperatures and periodic rain chances for the
region.
