DISCUSSION...
Thunderstorms have developed over southern Oklahoma and northern
Texas near a weak frontal boundary. The air mass across southeastern
Oklahoma is moist and unstable ahead of these storms. These
conditions will support a limited risk of severe weather through this
evening as the thunderstorms move eastward across the area. The
strongest storms will be capable of producing large hail up to
quarter size and wind gusts up to 60 mph.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY through Friday...Thunderstorm Potential.

EXTENDED DISCUSSION...
The frontal boundary is expected to remain near the Red River through
Sunday, supporting continued thunderstorm potential, especially
across southeastern Oklahoma and west central Arkansas. The front is
expected to move north across the region Monday and Tuesday,
supporting a chance of thunderstorms, and then move north of the area
by Wednesday. Another weak front is expected to approach the region
from the north late this week, continuing thunderstorm chances
through the end of the work week. Severe weather potential appears
low throughout the week.
