...DANGEROUS HEAT CONTINUES TODAY...

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

.DAY ONE...Today and Tonight.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.

    ONSET...After 2 PM.

DANGEROUS HEAT.
RISK...Significant.
AREA...Eastern Oklahoma and northwest Arkansas.
ONSET...After 12 PM.

 AREA AT GREATEST RISK...Northeast Oklahoma into west central Arkansas.

DISCUSSION...
Dangerous heat will develop again today across eastern Oklahoma
and west central Arkansas. The worst conditions are expected to begin
by midday and extend well into the evening. Heat index values
will range from 105 to 115 degrees. If you must be outside for
extended periods today, be sure to take breaks and stay hydrated.

A few showers and storms may develop this afternoon, mainly across
southeast Oklahoma into northwest Arkansas. Where storms occur,
dangerous cloud to ground lightning is likely, along with gusty
winds and heavy downpours.

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

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY and THURSDAY...Thunderstorm Potential...Dangerous Heat Potential.
FRIDAY and SATURDAY...Thunderstorm Potential.
SUNDAY and MONDAY...No Hazards.

EXTENDED DISCUSSION...

The hot and humid conditions will continue on Wednesday for much
of the area, though some relief is in sight. A cold front, which
has been across the Central Plains for the past few days, will
begin to sag south toward Oklahoma late Wednesday into Thursday.
This will be the focus for rain and storms beginning Wednesday
afternoon through the early part of the weekend.

There is the potential for some strong or isolated severe storms
on Wednesday and Thursday, with the main threat being from
damaging wind gusts. The unsettled pattern will bring a break from
the excessive heat. It will also bring a good chance for wetting
rain for much of the area through the weekend. The higher rain
totals of 1 to 2 inches are expected across far northeast Oklahoma
into northwest Arkansas.
