The heat sweeping through Ohio this week is intense<\/strong>, but it\u2019s not the worst the state has ever seen<\/strong>. Temperatures are expected to climb into the upper 90s\u00b0F (32\u201337\u00b0C)<\/strong>, with the heat index<\/strong> \u2014 factoring in Midwestern humidity<\/strong> \u2014 potentially reaching 104\u00b0F (40\u00b0C)<\/strong> or higher due to a heat dome<\/strong> gripping much of the country. But when exactly was the hottest day ever in Ohio<\/strong>?<\/p>\n <\/p>\n The hottest actual temperature ever recorded in Ohio<\/strong> \u2014 not accounting for humidity \u2014 occurred on July 21, 1934<\/strong>, near Gallipolis<\/strong>, in southern Ohio<\/strong>, when thermometers hit 113\u00b0F (45\u00b0C)<\/strong>. That stands as the state’s all-time high<\/strong>, based on historical weather records.<\/p>\n <\/p>\n That sweltering day in July 1934<\/strong> fell during one of the most infamous heat waves in U.S. history<\/strong>, part of the Dust Bowl era<\/strong>, which scorched much of the Great Plains<\/strong> and the Midwest<\/strong>. With relentless sun and a prolonged drought, Ohio<\/strong> experienced temperatures unlike anything seen before or since.<\/p>\n <\/p>\n As for the highest heat index ever recorded anywhere in the world<\/strong>, that title may belong to southern Iran<\/strong>. At Dayrestan International Airport<\/strong>, the heat index<\/strong> reportedly reached 180\u00b0F (82\u00b0C)<\/strong>, with a temperature of 180\u00b0F<\/strong> and a dew point of 97\u00b0F (36\u00b0C)<\/strong>, according to data from Global Climate Risks<\/strong>. It\u2019s considered possibly the highest heat index ever documented on Earth<\/strong>.<\/p>\n <\/p>\n Here in the United States<\/strong>, while this week\u2019s heat will be dangerously high<\/strong>, unless we surpass the 113\u00b0F (45\u00b0C)<\/strong> mark, Gallipolis<\/strong> will still hold the record for the hottest temperature ever measured in Ohio<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" The heat sweeping through Ohio this week is intense, but it\u2019s not the worst the state has ever seen.
