...ISOLATED SEVERE STORMS POSSIBLE TONIGHT, VERY DANGEROUS HEAT
AGAIN THURSDAY...

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

.DAY ONE...Today and Tonight.

SEVERE THUNDERSTORM.
 RISK...Limited.
 AREA...Northeast Oklahoma into Northwest Arkansas.
 ONSET...After midnight.

DISCUSSION...
Scattered thunderstorms are expected to develop across northeast
Oklahoma and northwest Arkansas through early Thursday morning.
While thunderstorm activity is expected to be poorly organized, a
few storms will be capable of producing damaging wind gusts,
large hail to quarter size and locally heavy rainfall. The
greatest threat for severe weather will be across far northeast
Oklahoma into northwest Arkansas, with a lessening concern further
west into the metropolitan Tulsa area and southward toward the
Interstate 40 corridor.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network is Not Likely.

THURSDAY...Thunderstorm Potential...Dangerous Heat Potential.
FRIDAY...Severe Thunderstorm Potential...Dangerous Heat Potential.
SATURDAY...Thunderstorm Potential...Dangerous Heat Potential.
SUNDAY AND MONDAY...Thunderstorm Potential.
TUESDAY...High Wind Potential...Dangerous Heat Potential.

EXTENDED DISCUSSION...
Dangerous heat and humidity will last at least into Thursday,
before rain and storm chances increase across the area through
the end of the week, likely providing some relief from the heat.
Scattered afternoon storms are possible across northeast Oklahoma
and northwest Arkansas on Thursday afternoon near a
frontal boundary. However, more widespread storm chances are
expected Thursday night as a storm complex sweeps southeast
across the region. Some storm potential will linger into the
weekend as well. The heat looks to build back in toward the middle
of next week as upper level ridging strengthens over the area.
