...VERY DANGEROUS HEAT CONTINUES INTO TOMORROW...


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

.DAY ONE... This evening.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.
AREA... West-central Arkansas and Eastern Oklahoma.
ONSET... Ongoing.

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

AREA AT GREATEST RISK... Eastern Oklahoma and west-central
Arkansas.

DISCUSSION...
Very dangerous heat continues at this time with much of eastern
Oklahoma and western Arkansas seeing heat index values in the 105
to 112 range. These elevated heat indices will continue into the
early evening hours before the sun sets and finally brings us
relief.

Also this evening... widely isolated thunderstorm development
remains possible across portions of eastern Oklahoma and west-
central Arkansas. Locally strong winds along with brief, heavy
downpours and dangerous cloud-to-ground lightning will be possible
with any thunderstorm that develops. Any ongoing thunderstorm
activity later this evening will quickly dissipate thanks to the
loss of daytime heating.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Dangerous Heat Potential.
WEDNESDAY...Thunderstorm Potential...Dangerous Heat Potential.
THURSDAY through SUNDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Another day of dangerous heat is expected tomorrow with many
locations seeing heat indices between 105 to 115 thanks to a
building ridge centered over the area tomorrow. This heat could
translate into Wednesday as well depending on any development of
showers or thunderstorms in the form of an MCS diving southward by
mid or late afternoon tomorrow which would bring relief from the
heat. The best chances for thunderstorms will tend to be over
northeast Oklahoma and far northwestern Arkansas tomorrow
afternoon and evening.

A cold front later this week will tend to reduce the heat index
for a majority of the region but it will increase our
thunderstorm chances for most of the area by Thursday. A limited
severe wind threat will be possible Wednesday through Friday with
locally heavy rainfall possible as well. Right now parts of
northeast Oklahoma and northwest Arkansas can expect 1 to
possibly 2 inches of rain over the next 7 days.
