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...Eastern Oklahoma and Northwest Arkansas.
ONSET...Late Afternoon.
DANGEROUS HEAT.
RISK...Significant.
AREA...Primarily Along and South of I-40.
ONSET...Midday.
DISCUSSION...
Scattered showers or thunderstorms could move into portions of
northeast Oklahoma this morning as a dying complex of storms drops
south out of Kansas. Severe weather is not expected with this
activity but some heavy downpours will be possible through the
morning hours. Additional thunderstorm development will be
possible along a weak boundary late Saturday afternoon and
evening. Profiles show potential for damaging downburst wind gusts
with the strongest storms as they potentially track across
northeast Oklahoma and into northwest Arkansas.
Otherwise, hot and humid conditions will build back into the
region this afternoon, particularly south of the weak boundary.
Heat index values of 105 to 110 degrees will be common this
afternoon, especially across southeast Oklahoma and west central
Arkansas.
SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.
.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Thunderstorm Potential...Dangerous Heat Potential.
MONDAY AND TUESDAY...Dangerous Heat Potential.
WEDNESDAY AND THURSDAY...Thunderstorm Potential...Dangerous Heat Potential.
FRIDAY...Thunderstorm Potential.
EXTENDED DISCUSSION...
Scattered showers and thunderstorms could be ongoing early Sunday
morning across parts of eastern Oklahoma and northwest Arkansas.
The severe weather threat should be waning by this time, but some
stronger storms could pose a risk of locally heavy rainfall and
gusty winds. Hot weather will steadily build into the region on
Sunday through much of the next week. Heat headlines will be
likely most days across the area. A potential stronger cold front
could arrive toward the end of next week, bringing increasing
thunderstorm chances and cooler temperatures.
