The National Weather Service in Knoxville has issued a weather forecast for the coming week with indications of persistent heat and chances of thunderstorms towards the weekend. According to the latest update, today's weather will begin with patchy fog before 9 a.m., eventually giving way to sunny skies and hot temperatures, with a high near 93 degrees and heat index values peaking at 101; a calm northeast wind is expected to develop in the afternoon.
This pattern of sunny and hot conditions is set to continue through Wednesday, with highs remaining in the low 90s, calm winds turning northeast around 5 mph each afternoon, and nightly temperatures expected to hover around the low 70s; the humidity is unforgiving, cloaking the mornings in a kind of mist that speaks less to the picturesque and more to the thick of sweat that will later envelop the city.
The forecast, as posted on the National Weather Service's website, suggests a slight dip in temperatures starting Thursday with highs near 90 and more cloud cover during the night. Heading into the weekend, there is a noted 20 percent chance of showers and thunderstorms on Friday after 2 pm and again on Saturday, with the sun dominating during the earlier parts of the day.
While the possibility of rain might offer some respite from the heat wave, the overall chance of precipitation remains low leading into Sunday; the sunny trend is expected to continue with a high near 86, the evenings promise to give that ephemeral reprieve from the day’s scorching clasp with lows dipping into the mid to high 60s providing some cooler moments just before daylight yields once again to the heat.
