Knoxville is bracing for a mix of heat and storms this week, with today marking the onset of variable conditions that could include severe weather. According to a report by NWS Knoxville, today's forecast includes a substantial chance of showers and thunderstorms, particularly post-4 p.m., as temperatures potentially soar near the 90-degree mark, paired with heat index values reaching as high as 98.
Residents can expect alternating periods of calm and storm through much of the week, including a "50 percent chance of showers and thunderstorms" tonight, mainly before 2 am, with a low around 71 degrees. The National Weather Service Morristown TN, warns of "isolated strong to severe storms" that may unleash damaging winds and cause localized flash flooding. On Tuesday, the chance of precipitation skyrockets to 100%, with "new rainfall amounts between a quarter and half of an inch possible," suggesting that the deluge is far from over.
Heading into Independence Day and the weekend, the weather takes a turn for the hotter. "Mostly sunny and hot" conditions with highs climbing into the low 90s are on the horizon, according to the National Weather Service. However, the "Hazardous Weather Outlook" foretells another concern: heat index values are projected to hit a scorching "between 100 and 105 across the southern valley near Chattanooga on Friday through the weekend."
The fluctuation in weather unlocks a potent mix of hazards: from the uncomfortable swelter to the potential for thunderstorm-triggered damages. "Any reports of wind damage and flooding are welcome through Tuesday," the NWS statement advises, in anticipation of "scattered to numerous afternoon and evening thunderstorms." Despite the looming adverse conditions, spotters are instructed to keep their eyes peeled and their lines open, as the "coverage of strong to severe storms is expected to be limited." But it's a clear indication that when it comes to weather, Knoxville truly is at the mercy of the elements.
