Heat indices will climb into triple digits across most areas west of I-35 on Thursday afternoon. Heat indices will exceed 105 degrees across much of western Oklahoma and adjacent western north Texas where a Heat Advisory and Extreme Heat Warning are in effect until sundown.

Isolated to widely scattered thunderstorms may develop along a dryline that will be located in the eastern Texas and Oklahoma panhandles this afternoon. Any storm that does develop will be capable of large hail and damaging wind gusts.

Symptoms of heat exhaustion include dizziness, thirst, heavy sweating, nausea, and weakness. Act fast by moving to a cooler area, loosening clothing, sipping cool water. Seek medical help if symptoms don't improve. Heat exhaustion can lead to heat stroke. Symptoms of heat stroke include confusion, dizziness, and becoming unconscious. Act fast by calling 911, moving the person to a cooler area, loosening clothing and removing extra layers, and cooling with water or ice. Heat stroke can cause death or permanent disability if emergency treatment is not given.

Showers and a few storms will be most possible across northern and western OK Thursday into Friday then shift southward Friday night into early Saturday. Precipitation will be light and have only temporary impacts on the heat.

The hottest conditions so far this summer will continue this week and into next week. There is a chance for precipitation late Thursday and Friday across northern into central Oklahoma.

There is a 60-70% probability that our temperatures will be likely above normal with near normal rainfall. The normal high temperatures going into early-August are in the mid to upper 90s while the normal low temperatures are in the lower 70s

Local Weather History For July 23rd...

Intense thunderstorms dumped copious amounts of rainfall over the
western parts of Oklahoma on July 23, 1979. Rainfall amounts were
quite impressive, including reports of up to seven inches just north
of Arapaho, in Custer County. Four inches of rain fell in just one
hour east of Arapaho and two inches of rain fell in only 30 minutes
in Clinton. Many creeks and rivers were quickly forced out of their
banks by the heavy rainfall. Floods covered the Arapaho-Weatherford
Road with as much as four feet of water. More than five inches of
rain fell in the Taloga area of Dewey County, causing Highway 183 to
be inundated by one to two feet of flood water.
