We are in store for another dangerously hot afternoon. Heat advisories and heat warnings are issued for much of the state and go into effect at noon today. Highs will reach into the upper 90s. Some locations, especially in central and western Oklahoma will top out at or above 100.
Heat index values this afternoon will once again be well into the triple digits. By late this afternoon, values will range from 105 to 112. Most of green country has heat advisories issued. Counties under a heat warning are in north central Oklahoma.
It is important to practice heat safety this afternoon. If you have to spend time outside today, stay hydrated and take frequent breaks in the air conditioning or shade. If you have friends or family who you know do not have air conditioning, be sure to check on them. Also do not leave children or pets in a vehicle or any amount of time.
Tonight storms should develop across western Kansas and the Oklahoma and Texas panhandles. Showers and storms will move east overnight tonight. There could be a few showers and storms still around for Friday morning.
A second wave will come through in the afternoon as a cool front approaches. There’s a chance for showers and storms tomorrow afternoon and tomorrow night. Several waves of showers and storms will come in through the weekend.
The cool front will sink into Oklahoma on Friday with greater chances for showers and storms in northeastern Oklahoma. A few storms on Friday could be strong to severe. By Friday evening we’ll see the front shift back north but an upper level wave coming across will keep shower and storm chances in the forecast for Saturday.
More widespread shower and storms are expected on Saturday. Additional waves will bring a chance for showers and storms again on Sunday. Timing still is not nailed down for Saturday or Sunday rain. Mostly cloudy skies and somewhat cooler air will bring afternoon highs back to near normal for Friday and Saturday. Dew points will still be high enough during the afternoons that heat index values will be near 100.
Dew points will be slightly lower for the start of next week but highs will warm back up again. We should be back in the mid to upper 90s by the middle of next week
