A little rain late Thursday broke the heat wave and made way for cooler temperatures Friday morning.
But a day that ushered Oklahomans to work with temps in the 70s, will soon heat up to triple digits.
According to meteorologist Alan Crone, Friday's highs across northeastern Oklahoma will be in the 105-111 range, despite a weak boundary that will move across the area. Any showers or storms either will be isolated across northern Oklahoma or will be concentrated across the far-southeastern part of the state.
Triple-digit weather is forecasted through the next six days, Crone said.
Thursday, which reached 107 degrees, was the 13th summer day of 100-plus temperatures. Crone expects the streak will extend to at least 19 days and possibly more.
The record high for Friday, set in 1938 and 1934, is 109 degrees. Crone has forecasted a high of 109 for Tulsa.
Thursday's official rainfall total from Tulsa International Airport was 0.32 inches, which brings July's total to 1.32 inches.
Rainfall for the year is still down 4.50 inches, Crone said.
