Isolated storms, humid weather for the 4th

By  | 

CEDAR RAPIDS, Iowa (KCRG-TV9) - For most, Independence Day will be a dry but muggy day. Isolated storms may develop in the afternoon. While anything that pops up will be few and far between, if you see lightning or hear thunder, get inside until the storm passes. These should go away as the sun goes down, so dry weather is expected during fireworks. Additional storms are possible late Wednesday night.

Regarding the heat, highs will climb to around 90 in the afternoon. Dew points in the 70s, probably a little higher than on Tuesday, will make it feel oppressive. Heat indices near 100 are likely in the afternoon. With so many outdoor activities, it’ll be especially important to pay attention for signs of heat-related illness, take breaks, and stay hydrated with water or sports drinks.

Heat exhaustion symptoms include being faint or dizzy, excessive sweating, cool and clammy skin, nausea or vomiting, as well as a rapid or weak pulse. Muscle cramps may also occur.

Heat stroke symptoms include a throbbing headache, no sweating, body temperature above 103 degrees with red, hot skin, and nausea or vomiting. A rapid, strong pulse may accompany these and it’s possible you may lose consciousness. Heat stroke is an emergency and can be fatal.
