TULSA, OKLA — An unseasonably strong area of high pressure remains over Oklahoma through the end of the week.

Temperatures gradually cool back into the mid/upper 70s by Friday morning with another hot day awaiting us. Highs will again be in the upper 90s. Thankfully, humidity will drop off a bit, limiting the heat index to around 100° for the afternoon.

Winds are expected to increase Saturday as drier air moves into the region. The combination of hot temperatures, lower humidity and stronger winds could allow fires to start more easily and spread quickly, particularly across eastern Oklahoma where larger timber fuels are present. Saturday may be Tulsa's last 100° day of the year before a pattern change heading into next week.

A cold front will make a slow approach late in the day Sunday with a rising rain chance throughout the day. Showers and storms may also linger into Monday as temperatures cool back into the 80s for highs and 60s for lows.

Seasonably mild to warm temperatures stick around for the rest of next week with limited rain chances.
