The forecast is especially important for cities located under the path of totality on Monday, such as San Antonio (Texas), Little Rock (Arkansas) and Carbondale (Illinois) Although the forecast will not be accurate until about 24 to 48 hours before the eclipse, skies are expected to be clear throughout New England. Eastern Indiana, northern Ohio and western New York currently have a more than 50% chance of cloudy skies during the eclipse.

Texas is also showing a tendency to become cloudy due to the arrival of a storm system that could carry a risk of severe thunderstorms.
