While <strong>Northern Michigan<\/strong> will be largely spared from the brunt of the heat, the <strong>southeast<\/strong> corner\u2014including <strong>Detroit<\/strong>, <strong>Ann Arbor<\/strong>, and <strong>Monroe<\/strong>\u2014is about to feel the <strong>full force<\/strong> of a classic <strong>hot dome<\/strong> formation in the upper atmosphere.<\/p>\n<p>&nbsp;<\/p>\n<p>Beginning <strong>Saturday, June 21<\/strong>, and lasting through <strong>Thursday, June 26<\/strong>, the <strong>upper-air pattern<\/strong> will trap a large mass of <strong>scalding air<\/strong> over the <strong>Midwest<\/strong>, with the <strong>core of the heat dome<\/strong> centered over <strong>Kentucky<\/strong> and <strong>West Virginia<\/strong>, but extending fully into <strong>Southeast Michigan<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Detroit<\/strong> and nearby areas may flirt with <strong>100\u00b0F (38\u00b0C)<\/strong>\u2014something that hasn&#8217;t happened in more than a decade. If those readings are reached, they would mark the <strong>highest temperatures recorded<\/strong> in the region since the <strong>summer of 2012<\/strong>.<\/p>\n<p>&nbsp;<\/p>\n<p>Unlike recent hot spells that have sometimes approached from the <strong>northwest<\/strong>, this episode will push in from the <strong>southeast<\/strong>, heating up the <strong>urban pavement corridors<\/strong> of <strong>Metro Detroit<\/strong> with remarkable intensity. The <strong>urban heat island effect<\/strong> will amplify daytime highs, particularly in <strong>concrete-heavy zones<\/strong>, possibly pushing readings <strong>2 to 4 degrees higher<\/strong> than surrounding rural areas.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Monday, June 23<\/strong>, is expected to be the <strong>peak of this hot stretch<\/strong>, with widespread highs in <strong>Southeast Michigan<\/strong> climbing to between <strong>96\u00b0F and 100\u00b0F (36\u00b0C to 38\u00b0C)<\/strong>. Highs will stay in the <strong>90s (32\u00b0C+)<\/strong> for much of the week across the <strong>southern counties<\/strong> of the <strong>Lower Peninsula<\/strong>, with some areas logging <strong>five to six consecutive days<\/strong> above the <strong>90\u00b0F (32\u00b0C)<\/strong> threshold.<\/p>\n<p>&nbsp;<\/p>\n<p>In contrast, <strong>Northern Michigan<\/strong>, including cities like <strong>Traverse City<\/strong>, will likely see only <strong>one or two days<\/strong> above <strong>90\u00b0F (32\u00b0C)<\/strong>\u2014primarily between <strong>Sunday and Wednesday<\/strong>\u2014with temperatures generally retreating by the end of next week.<\/p>\n<p>&nbsp;<\/p>\n<p>By <strong>Thursday, June 26<\/strong>, models suggest a slight <strong>cooling trend<\/strong> could begin to break down the heat dome. However, with <strong>June not yet over<\/strong>, it&#8217;s reasonable to expect <strong>more 90-degree days<\/strong> later this <strong>summer<\/strong> across the <strong>Great Lakes region<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A scorching dome of heat targets Southeast Michigan A severe heat wave is about to grip the southern half of Lower Michigan, marking what could be the most intense stretch of hot weather the state has experienced since 2012.
