Forecast Summary

Hot and humid weather continues on Thursday, with a Heat Advisory again posted for parts of west-central Arkansas. These areas are where the highest heat index values are expected.

Hot and humid conditions persist through this week across eastern Oklahoma and northwest Arkansas. Be aware of signs of heat stress and take precautions with outdoor activities.

Isolated thunderstorms will become possible again by this afternoon, primarily in the terrain areas of far eastern Oklahoma and northwest Arkansas each afternoon. Organized severe weather is not expected, but brief heavy downpours and gusty winds could accompany any storm.

Hot and humid conditions are on deck for the afternoon and evening of July 4th. Mother Nature may provide some fireworks of her own in southeast Oklahoma and western Arkansas, with a low chance of thunderstorms.

With June 2026 wrapped up, the temperature and precipitation statistics for Tulsa, Fort Smith and Fayetteville confirm that it was a climatologically wet month for all 3 sites, with Tulsa and Fort Smith averaging slightly below normal high temperatures and above normal low temperatures. Fayetteville ended up with above normal high and low temperatures for the month. We wonder what July will bring!

Hot and humid weather will persist through the rest of the week and through the July 4th weekend. Daily low chances for showers and thunderstorms will develop in southeast Oklahoma and western Arkansas late this week, increasing in coverage and spreading west late in the weekend.
