TULSA, Oklahoma - Showers and storm chances for Green Country on Friday. A cool front is moving into the area, but the only cool air we could see today will be from rain and thunderstorms.

Skies will be mostly cloudy at times today but over partly cloudy the afternoon. Temperatures will climb to near 90 by lunch time today. Heat index values will be high again today because of high humidity.

Afternoon highs will have the potential to make it into the low to mid-90s. If we see showers and thunderstorms continue through the earlier afternoon, then that will knock down daytime highs.

There is a chance this afternoon that storms could become severe. The main storm zone today includes counties north of Interstate 40. Storms will be capable of 60- to 70-mile-per hour wind gusts and hail around 1 inch or higher.

Storms should begin across Green Country early this afternoon along the sagging cool front. Highest chances for showers and storms will be north of I-40.

If the atmosphere is able to destabilize again after morning activity, then strong to severe storms will be possible again this afternoon. It is important to stay weather aware.

Storms could last well into the evening hours and overnight.

On Saturday, the boundary will lift back to the north and stall across southern Kansas. Several waves of upper level energy will come across enhancing chances for showers and storms again on Saturday and Sunday.

Chances for severe storms are less on Saturday as the upper-level forcing does not look as strong, but there could still be one or two that organize.

Daytime highs will be near normal through the weekend before a warming trend starts up again next week. Saturday should be partly cloudy with highs in the low- to mid-90s. There does not seem to be any significant relief from the heat for quite a while.
