Record-breaking temperatures persist across Delaware<\/strong><\/p>\n DELAWARE \u2013 Friday, June 21, 2025, 9:00 AM (ET)<\/strong> \u2013 The heat dome<\/strong> that has settled over much of the Mid-Atlantic<\/strong> and Northeast<\/strong> is now producing extreme heat<\/strong> across Delaware<\/strong>, with temperatures well into the upper 90s\u00b0F (35\u201338\u00b0C)<\/strong> and heat index values<\/strong> topping 105\u00b0F (over 40\u00b0C)<\/strong> in several locations. This dangerous heat wave<\/strong>, which began earlier this week, is expected to persist through the weekend<\/strong>, pushing humidity levels<\/strong> to oppressive levels and raising growing concerns for public health and infrastructure<\/strong>.<\/p>\n Excessive heat warning in effect<\/strong><\/p>\n The National Weather Service<\/strong> has issued an Excessive Heat Warning<\/strong> for New Castle<\/strong>, Kent<\/strong>, and Sussex Counties<\/strong>, in effect through Saturday evening<\/strong>, with possible extensions into Sunday<\/strong> depending on how the system evolves. Highs today across Wilmington<\/strong>, Dover<\/strong>, and Rehoboth Beach<\/strong> are forecast to reach 98\u00b0F (36.7\u00b0C)<\/strong>, with “feels-like” temperatures<\/strong> surpassing 110\u00b0F (43.3\u00b0C)<\/strong>, particularly in urban areas<\/strong> with limited overnight cooling.<\/p>\n Unrelenting heat amplified by stagnant air<\/strong><\/p>\n This heat dome phenomenon<\/strong>, a persistent ridge of high pressure<\/strong>, continues to trap hot, moist air<\/strong> over the region. Winds remain light<\/strong>, and skies are mostly clear<\/strong>, allowing maximum solar heating. With nighttime lows<\/strong> hovering around 78\u00b0F (25.5\u00b0C)<\/strong> in the cities, there is little relief after sunset<\/strong>, keeping indoor temperatures elevated<\/strong> and stress on cooling systems high<\/strong>.<\/p>\n Impact on health, energy, and transportation<\/strong><\/p>\n Officials in Delaware<\/strong> have reported an uptick in emergency calls<\/strong> related to heat exhaustion<\/strong> and heatstroke<\/strong>, particularly among outdoor workers<\/strong>, elderly populations<\/strong>, and those without air conditioning<\/strong>. Utility companies<\/strong> across the state are urging residents to be mindful of electricity usage<\/strong>, as power demand<\/strong> approaches seasonal peaks. Meanwhile, transportation departments<\/strong> are monitoring roadways<\/strong> and rails<\/strong> for signs of heat-related buckling<\/strong>.<\/p>\n Weekend outlook: Continued high heat, slight relief next week<\/strong><\/p>\n Forecast models suggest that the heat dome<\/strong> will begin to weaken gradually<\/strong> by Monday<\/strong>, with a cold front<\/strong> possibly moving into the region by Tuesday<\/strong>, bringing thunderstorms<\/strong> and slightly cooler air<\/strong>. Until then, the heat wave<\/strong> will maintain its grip on Delaware<\/strong>, with Saturday<\/strong> highs again near 97\u00b0F (36.1\u00b0C)<\/strong> and Sunday<\/strong> only marginally cooler.<\/p>\n The intensity<\/strong> and duration<\/strong> of this event make it one of the most significant June heat waves<\/strong> in Delaware’s<\/strong> recorded history.<\/p>\n","protected":false},"excerpt":{"rendered":" Record-breaking temperatures persist across Delaware DELAWARE \u2013 Friday, June 21, 2025, 9:00 AM (ET) \u2013 The heat dome that has settled over much of the Mid-Atlantic and Northeast is now producing extreme heat across Delaware, with temperatures well into the upper 90s\u00b0F (35\u201338\u00b0C) and heat index values topping 105\u00b0F (over 40\u00b0C) in several locations.
