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...Significant.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

	AREA AT GREATEST RISK...Northeast Oklahoma and Northwest Arkansas.

HEAVY RAIN AND FLASH FLOOD.
	RISK...Limited.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Ongoing.

DANGEROUS HEAT.
	RISK...Elevated.
	AREA...Eastern Oklahoma and West Central Arkansas.
	ONSET...Ongoing Through Early Evening.

DISCUSSION...
Thunderstorms will continue to develop along a southeastward
moving frontal boundary over northeast Oklahoma and northwest
Arkansas this evening, and then into southeast Oklahoma tonight.
Increasing severe potentials into this evening will support the
threat for large hail and damaging winds. Overnight, storms are
expected to be more linear with the threat transitioning to mainly
locally damaging wind gusts. Overall severe potentials, weaken
overnight, though thunderstorm chances continue across southeast
Oklahoma and west central Arkansas into early Friday morning. In
addition to the severe threat, quick heavy rains could lead to a
local flash flood risk into tonight.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Expected.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...Thunderstorm Potential.
SATURDAY...Severe Thunderstorm Potential...High Wind Potential...Heavy
		   Rain Potential.
SUNDAY...Thunderstorm Potential...Heavy Rain Potential.
MONDAY AND TUESDAY...Thunderstorm Potential.
WEDNESDAY...High Wind Potential.

EXTENDED DISCUSSION...
Shower and storm activity should be ongoing in southeast Oklahoma
Friday morning, and then diminish during the day. Additional storms
are forecast Friday night into Saturday morning across far
northeast Oklahoma and northwest Arkansas as one or more nocturnal
storm complexes move through the region. The front that crosses
our area tonight and Friday will redevelop north Saturday and be
the focus for widespread thunderstorm development late Saturday
afternoon and evening in southern Kansas to northern Oklahoma.
These storms will pose an excessive rain threat and some severe
storm potential. Measurable rain will fall across most if not all
of eastern Oklahoma and northwest Arkansas Saturday night into
Sunday while a cold front moves into the region. Local rainfall
amounts of 3 to 5 inches, though an isolated amount near 7 inches
is not out of the question given the current data.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Emergency managers should continue to closely follow the forecast
into the weekend. Severe weather operations will be necessary at
times. The main concern appears to be the potential for excessive
rain. Flash flooding concerns will increase over the next several
days. The excessive rains, depending on exactly where they fall,
could easily aggravate creek and river flooding.
