The National Weather Service in Knoxville has released a forecast for the coming days, indicating that residents in the area can expect a series of hot and partly sunny days ahead, with sporadic chances for showers and thunderstorms. The weather pattern is noted for its mostly clear skies accompanied by high heat index values, with today being particularly warm with the possibility of thunderstorms developing later in the afternoon. According to the latest update from the NWS, the chance for these showers and thunderstorms today sits at 30 percent.

Temperatures today are expected to soar near 93 degrees Fahrenheit, while heat index values might make it feel as stifling as 98 degrees; tonight, the mercury will modestly dip to around 72. Similar conditions are anticipated for Tuesday, with heat once more enveloping the area and the high predicted to be near 92 degrees but feeling close to 98, the calming winds providing little reprieve from the sweltering heat. The forecast for Juneteenth also promises more of the same: heat, partial sunshine, and practically still air with the day's high around 90 degrees.

As the week progresses, Knoxville will continue to bask in warmth with highs consistently in the low 90s and minimal cloud cover noted for most days. Wednesday night predicts a slight alteration in wind direction, shifting from northeast to calm, and carrying overcast conditions that will introduce a modest drop in nighttime temperatures to around 69 degrees. Moreover, with Friday ramping up to an anticipated high of 95, the ongoing heatwave suggests no significant changes in the overall pattern, maintaining a dry and scorching atmosphere well into the weekend.

Looking towards the weekend, residents should prepare for continuous heat with highs expected to peak at 96 degrees on Saturday, though the NWS does forecast a slight 20 percent chance of rain and possibly thunderstorms. Saturday night's potential for precipitation weakens further to a mere 10 percent, while temperatures during the night are estimated to stay relatively warm at about 74 degrees. Sunday carries a slightly increased likelihood of rain, with a 40 percent chance of showers and thunderstorms projected amid another typically hot and mostly sunny day featuring a high near 94 degrees.
