Tulsa, OK – Residents across eastern Oklahoma and northwest Arkansas can expect unseasonably hot and dry weather through the next week, according to the National Weather Service (NWS) in Tulsa.
Forecasts show daytime highs climbing into the mid-to-upper 90s from Friday, September 12, through much of next week. Tulsa is expected to reach 95°F Friday and remain above 90°F into Thursday, September 18. Overnight lows will stay warm as well, ranging from the upper 60s to low 70s.
According to the NWS, rain chances remain minimal, with only a slight 10–20% probability of precipitation late Wednesday into Thursday. Until then, most of the region will stay dry.
Meteorologists warn that heat stress potential will be elevated Friday and Saturday. The Wet Bulb Globe Temperature (WBGT), which measures the combined effect of temperature, humidity, and sun exposure, is expected to reach “moderate” levels in many areas. This means outdoor workers and those exercising in direct sun should take at least 30 minutes of rest per hour. Areas in the “high risk” zone may require even longer breaks.
Communities including Tulsa, Muskogee, Fort Smith, and McAlester are urged to take precautions while outdoors, especially during peak afternoon hours. Hydration, shade, and frequent breaks are recommended to prevent heat-related illness.
Temperatures are forecast to trend slightly lower late next week, but conditions will remain warmer than normal for mid-September.
