...SEVERE STORM POTENTIAL TODAY...

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

.DAY ONE...Today and Tonight.

SEVERE THUNDERSTORM.
	RISK...Significant.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...Limited risk this morning...higher severe chances this afternoon

	AREA AT GREATEST RISK...Northeast Oklahoma...and far Southeast Oklahoma.

FLASH FLOOD.
	RISK...Limited.
	AREA...Northeast Oklahoma.
	ONSET...This Afternoon.

DISCUSSION...
Thunderstorms that moved through northeast Oklahoma and northwest
Arkansas last night have pushed well east of the area. Focus will
now turn towards additional development across south central
Oklahoma...as well as storms to the north and west along an
approaching cold front.

Activity currently across south central Oklahoma likely will push
into portions of southeast Oklahoma later this morning. While
instability across this area was not hampered from overnight
convection...severe potential with these storms is expected to
remain limited during the morning hours.

By early afternoon...cold air aloft associated with the upper low
will aid in destabilizing the atmosphere across northeast Oklahoma
ahead of the approaching cold front. Scattered storms that can
develop ahead of the front will carry a large hail threat to the
size of tennis balls...especially across northeast Oklahoma during
the early afternoon. As the front progresses further east and
southeast...the severe threat will transition towards damaging
straightline winds as storms organize into a line along the front.

Across far southeast Oklahoma later in the afternoon...it is
possible that instability will be maximized should that area
remain convection free up to that point. Wind gusts to 70 mph
will be possible with severe bow segments should that environment
remain most favorable ahead of the front.

Additionally...soils remain saturated across much of northeast
Oklahoma from recent rainfall. While areal flooding and mainstem
river flooding have subsided...additional rainfall across
northeast Oklahoma may result in a quick uptick in rises for area
rivers...and also may create additional flooding issues given the
saturated conditions in place.

The risk for severe weather will diminish during the evening as
the front moves further away from the area. Thunderstorms will
likely continue the overnight period...especially across
northeast Oklahoma and northwest Arkansas as the upper low clears
the area.

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

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY Through MONDAY...No Hazards.
TUESDAY and WEDNESDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Cooler and settled conditions will settle across the area from west to
east on Friday. Warmer temperatures are expected through the
weekend and will continue into at least the first part of next
week. Thunderstorm chances will be on the increase once again in
the Tuesday and Wednesday as an upper system to the northwest
begins to impact the region.
