Residents of Knoxville and surrounding regions woke up to dense fog this morning, with visibility sharply reduced to a mere 0.15 miles in some areas, particularly impacting the northern parts. According to the National Weather Service (NWS) Knoxville, the foggy conditions were expected to lift shortly after daybreak, especially in areas close to the Kentucky and Tennessee state lines as well as Virginia counties. Humidity stood at 100%, and with the fog dispersing, temperatures were forecasted to climb, signaling a hot day ahead.
The NWS update indicated that today's weather would transform to be partly sunny, eventually clearing up to a searing high near 90 degrees, with heat index values feeling as sweltering as 96. The evening is expected to remain mostly clear, with the lows hovering around a comfortable 70 degrees. The calm wind will provide little relief from the day's heat. This comes as the NWS issues a hazardous weather outlook for portions of southwest North Carolina, east Tennessee, and southwest Virginia, but no significant hazardous weather is expected to follow past the morning fog.
Looking forward into the week, Knoxville's forecast suggests continuous hot and sunny days with chances of showers and thunderstorms developing each afternoon from Monday, with a slight uptick expected by Friday. Monday, August 5, forecasts a high near 92 degrees and heat index values that could soar to 101, while the rest of the week shows similar high temperatures persisting. The region remains under no immediate threat of severe weather, as the NWS has noted that the probability of widespread hazardous weather is low.
Residents planning outdoor activities are advised to do so cautiously, especially in the afternoon heat, and to stay vigilant for updates on potential thunderstorms. The weather pattern extending into Saturday includes daily chances of showers and thunderstorms, mostly in the afternoon, with the likelihood increasing slightly by the end of the week.
