As you celebrate America turning 242 years young, here’s what you need to know to stay weather ready:

 

Warm and muggy air in St. Louis, Missouri, could spark a few thunderstorms through July 4, 2018.  Be sure to check your local forecast at www.weather.gov before you make your plans. Happy Independence Day!

Eastern states will start to see a decline in high temperatures as the weekend progresses. Showers and thunderstorms will develop along the southern Mid-Atlantic region, dropping down across the Southeast and Gulf Coast states on Saturday. This front will remain an active focus for showers and thunderstorms through the weekend. 

Meanwhile, the northern High Plains and the upper Midwest will see a resurgence of hot temperatures. Temperatures will locally be approaching 100 degrees on Saturday across the Dakotas. Scattered showers and thunderstorms are a possibility and some heavy rainfall over eastern North Dakota and northern Minnesota. The Desert Southwest will remain hot and dry with some additional record high temperatures through Saturday especially across southern California. 

Keep an eye out for these 3 hazards

  • Beware of nature’s fireworks: lightning. In fact, July is the most lethal month for lightning – so, please remember: "When thunder roars, go indoors."

  • As always, use caution when barbequing outdoors, setting off fireworks or conducting any activities with open flames as they can become a fire hazard, especially in areas that are very dry and more prone to wildfires such as in parts of the western U.S. this week. Be sure to follow the advice of local officials regarding any restrictions for open flames.

  • Rip currents can also be a hidden danger to those entering the water, so it’s important to stay out of restricted areas of the beach, swim where there is a lifeguard and know how to survive a rip current if you get caught up in one.
