High heat and humidity, feeling warmer, and seeing isolated showers and storms develop ... sounds like summer in East Tennessee on this last weekend of April.
Isolated showers and storms are developing along the Northern Plateau and Southeastern Kentucky. There's a 20% chance for storms in this area, with a stray shower or storm in East Tennessee. They can be stronger to severe. Tonight comes with scattered clouds for most of East Tennessee, with a light breeze, and a very warm low of 65 degrees. Sunrise 6:46 a.m.
Saturday will be hotter, even record-breaking. We're aimed at a high of 91 degrees, and the previous record for that date is 88 degrees from 1872. Not only will it be hot, but it will also be humid, so it will feel a few degrees warmer and even worse in the sunshine. While most of the day is just hot and humid, an isolated shower or strong storm could develop because of these ingredients. We'll find the wind speeds increasing at times in the afternoon hours, with gusts of 20+ mph.
Sunday will be warm as well, as we top out in the upper 80s and it will still be humid, and an isolated shower or storm is possible.
Scattered rain and storms will approach Sunday night into Monday, as we go to a 60% chance for rain and storms. We'll be closer to a normal high then, around 74 degrees.
We'll get a break from rain Tuesday, with a few clouds and a high of 76 degrees.
Wednesday will be warmer, in the upper 70s, and isolated showers and storms will be possible.
The chance for rain and storms increases Thursday and Friday, with a cold front pushing temperatures into the upper 50s to low 60s for highs by the end of next week.
Have a great day and a wonderful weekend!
