Thunderstorm,rain likely tomorrow
NWS, the American and the European model put Kingsport's high today between 85° and 91°, a 6° split. Tomorrow looks light rain around 86°, with a 78% chance of rain.
Kingsport is a town of about 53,000 people in TN, sitting at 36.5°N in a temperate climate zone. NWS, American, European each forecast Kingsport with their own physics, so we line all three up and flag where they disagree. Nearby towns include Bloomingdale, Colonial Heights, Mount Carmel.
We grade every model against the weather that actually happened, so you can see which forecast model is most accurate in United States before you trust any single number.
The CheckWeather Score blends temperature, wind and rain accuracy — each measured against ERA5 (the recorded weather) over the last 30 days across 1999 cities. Lower error means a higher score. See which forecast model is most accurate in United States, how we measure forecast accuracy, or which model each weather app uses.
The models often agree on temperature and still split on rain — and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
