This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.
.DAY ONE...Today and Tonight.
DANGEROUS HEAT.
RISK...Significant.
AREA...Eastern Oklahoma and Northwest Arkansas.
ONSET...Midday.
AREA AT GREATEST RISK...Northeast Oklahoma to Arkansas River Valley
of West Central Arkansas.
DISCUSSION...
Dangerous heat conditions continue across eastern Oklahoma and
northwest Arkansas with heat index values 105 to 110 degrees this
afternoon. Conditions begin to slowly improve this evening, though
little heat relief is expected overnight tonight.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY AND MONDAY...Thunderstorm Potential...Dangerous Heat Potential.
TUESDAY...Dangerous Heat Potential.
WEDNESDAY THROUGH FRIDAY...Thunderstorm Potential...Dangerous Heat Potential.
EXTENDED DISCUSSION...
Ongoing dangerous heat and heat stress persist into Sunday while a
weak frontal boundary sags southward into the region. Moisture
pooling along this boundary will help to create heat index values
of 105 to 110 degrees and locally higher again Sunday afternoon.
Isolated to scattered shower and thunderstorm chances develop with
the frontal boundary Sunday late afternoon and remain possible
into Monday. Localized strong downburst winds look to be the main
threat with the stronger storms. The greater potential is forecast
over northeast Oklahoma into northwest Arkansas. Additional storm
chances return during the second half of next week as the ridge of
high pressure tries to retreat westward. Even with the rain
chances through the upcoming week, hot and humid conditions remain
forecast as well for eastern Oklahoma and northwest Arkansas.
