Dangerous Heat Wave Continues; Areas of Severe Thunderstorms Today

Dangerous, record-breaking heat will continue across most of the central and eastern U.S through Friday then focusing on the eastern U.S. through the Independence Day weekend. Peak heat indices of up to 115 degrees are possible. Strong to severe thunderstorms will be possible from the northern Plains into the Midwest and Great Lakes regions, as well as across the southern Appalachians today. Read More >


...Heat and Humidity Continue Friday, Not as Hot July 4, Storms Possible... * Record-level heat and humidity continues into Friday with little change. Temperatures will be hottest Friday in the Bangor Region and Downeast. July 4th will still be on the warmer side but Sunday will turn cooler. * How about rain/storm chances? So far, we have dodged the bullet. Strong/severe storms have passed to the north and southwest of our area, while we have been quiet. The air over the region is potentially extremely unstable, but we have lacked the trigger to ignite strong/severe storms. That said, we are keeping a close eye on things, as there's around a 20 percent chance of storms, and if any do form, they could be severe. A few storms are possible late Friday and again on Saturday, but chances are generally 40 percent or less.
Heat Safety tips - pay special attention to vulnerable populations including, infants and children, older adults, those with chronic illnesses, and those who are pregnant.
Keep your pets indoors during the heat and never leave in a car. Animals can die of heatstroke within 15 minutes. Cracking car windows is not enough.

For Moderate/High/Extreme hazard risk, more detailed information will be provided via emailed briefings to core partners.
