Showers/Thunderstorm Potential on the 4th of July (posted July 3, 2018)
There will be a chance of showers and thunderstorms mainly from Wednesday afternoon, through Wednesday night and into Thursday. The best likelihood of seeing thunderstorms would be late Wednesday evening through the rest of Wednesday night. It is during this time frame where a few of these storms may become strong to severe with damaging winds being the primary threat. There is a slight risk of severe thunderstorms generally west of a line from Iron Mountain to Wausau.
In addition to the threat of thunderstorms, very warm and humid conditions are expected on Independence Day. High temperatures in the upper 80s to lower 90s away from Lake Michigan, combined with the humidity, will likely generate heat indices from 95 to 100 degrees.
Anyone with outdoor plans on the 4th of July should keep abreast to changing weather conditions. Be ready for the potential of strong thunderstorms and the hot/humid conditions.
There is medium confidence that a chance for showers and thunderstorms will occur. There is higher confidence for the heat and humidity expected on Independence Day.
