This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.
.DAY ONE...This Afternoon and Tonight.
DANGEROUS HEAT.
RISK...Significant.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing.
DISCUSSION...
Dangerous heat conditions continue, with afternoon heat index
values from 110 to 115 degrees in much of northeast Oklahoma and
the Interstate 40 corridor and 105 to 110 degrees in the remainder
of the area. Conditions will begin to slowly improve this
evening, though little heat relief is expected overnight with lows
only in the upper 70s to lower 80s in most spots.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY AND MONDAY...Thunderstorm and Dangerous Heat Potential.
TUESDAY...Dangerous Heat Potential.
WEDNESDAY...Thunderstorm and Dangerous Heat Potential.
THURSDAY AND FRIDAY...Dangerous Heat Potential.
EXTENDED DISCUSSION...
Ongoing dangerous heat and heat stress potential persist into
Sunday while a weak front sags southward into the region.
Moisture pooling along this boundary will help to create heat
index values of 105 to 115 degrees again Sunday afternoon.
Isolated to scattered showers and thunderstorms are expected to
develop with the front late afternoon Sunday and remain possible
into Monday afternoon. Localized strong downburst winds will be the
main threat with the stronger storms, likely across northeast
Oklahoma and into northwest Arkansas.
The front will bring a minor cooldown to areas north of Interstate
40 Monday, although heat stress conditions will persist across the
southern half of the area. Any break in the heat will be short-
lived with very hot conditions returning areawide Tuesday.
Low storm chances return during the second half of next week as
upper level high pressure retreats westward. Even with the rain
chances through the upcoming week, hot and humid conditions remain
forecast as well for eastern Oklahoma and northwest Arkansas.
