Fourth of July Outlook

Expect warm temperatures across Montana this holiday weekend, with highs climbing steadily from the 70s on Friday into the mid-80s and 90s by Sunday. While most of the weekend looks great for outdoor celebrations, there are daily chances for scattered thunderstorms, primarily localized East of the Continental Divide. Though the overall probability of severe weather remains low, any developing storm could bring localized hazards. Safety Impacts: Fireworks & Wind: Even non-severe thunderstorms can produce gusty, erratic winds. Be highly mindful of sudden wind shifts if you are lighting fireworks. Lightning: Outdoor gatherings are highly vulnerable to lightning strikes. Take shelter inside a sturdy building or hard-topped vehicle at the first sign of lightning or thunder. Heat: With temperatures pushing into the 90s by Sunday, remember to drink water before you feel thirsty and reapply SPF 30+ sunscreen every two hours.
