...High heat index values expected today...

Very warm temperatures coupled with high humidity will produce
heat index values between 103 and 107 degrees. Heat index values
may be highest along the coast with higher humidity. A heat
advisory may yet be required later today if heat index values of
108 or higher become likely. Heat index values should be lower
Monday and Tuesday with increased cloud cover due to shower and
thunderstorm activity. This may limit high temperatures to the mid
90s instead of the upper 90s.

Whether or not heat advisories are issued, you need to protect
yourself and others from the impacts of the heat. If outside, stay
hydrated, take breaks in the shade as often as possible and limit
strenuous activities. If driving, never leave kids, pets or
anyone with limited mobility alone in a vehicle for even a few
minutes as rapidly rising temperatures could reach dangerous or
even deadly levels. Remember to look before you lock! Know the
signs of heat stress and seek medical attention if you suspect
that you or someone else is experiencing heat illness.

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...Northeastern Oklahoma and West Central Arkansas.
ONSET...Ongoing.

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

DISCUSSION...
Temperatures in the 90s, combined with high humidity, have resulted
in heat index values from 105 to 110 degrees across much of eastern
Oklahoma and west central Arkansas this afternoon. A Heat Advisory
remains in effect into this evening, with conditions improving around
sunset.

Strong heating of the moist air mass that persists across the area
today has resulted in the cap being eroded across the region.
Isolated thunderstorms have developed in this air mass, but due to
the lack of any low level focus and the lack of wind shear, this
activity will likely remain short-lived and isolated into the
evening, and then gradually dissipate entirely around sunset. The
strongest storms will be capable of producing strong wind gusts.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...Thunderstorm Potential.
TUESDAY...Thunderstorm Potential...Heavy Rain Potential.
WEDNESDAY...Thunderstorm Potential.
THURSDAY...No Hazards.
FRIDAY and SATURDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Hot and humid conditions will continue on Monday along with isolated
afternoon and evening thunderstorms. A cold front is forecast to
move through the area on Tuesday with hot temperatures again
preceding the cold frontal passage. Widespread showers and
thunderstorms are expected Tuesday afternoon through Tuesday night as
the front pushes southward. Locally heavy rainfall is possible
Tuesday night, along with limited severe weather potential. Showers
and thunderstorms end on Wednesday, with noticeably cooler
temperatures for late week. Another system moving through the
Southern Plains will bring increased thunderstorm chances back to the
area by Saturday.
