TULSA, OK -- Weather forecasters say intense heat has returned to Oklahoma after Thursday's brief reprieve.
News On 6 meteorologist Alan Crone says an excessive heat warning remain effect for today for the Tulsa metro area and a heat advisory for the rest of eastern Oklahoma.
Highs in the upper 90s combined with low level moisture may create heat index values from 100 to 105.
Crone says a gusty south wind at 10 to 20 mph will also be present.
The mid level ridge of high pressure will be building over the state today and tomorrow. This will allow hot temperatures to return with highs in the upper 90s or near 100. The low level moisture content may dry slightly Saturday with a southwest surface component in the wind field, and this may allow slightly lower temperature heat index values.
There have been no deaths officially attributed to the extreme heat, but the EMSA in Tulsa and Oklahoma City has reported receiving just under 300 heat-related calls.
