Gusty thunderstorms will target the northeastern United States on Monday, but will fail to sweep away the baking heat wave gripping the region.
Dangerous heat will surge northward and send temperatures soaring across the northwestern United States during the final week of July.
Downpours will spread from the lower Mississippi Valley to eastern and central Texas early this week, delivering needed rain but raising the concern for flash flooding.
A renewed risk of severe weather will threaten portions of the north-central United States early this week.
With the heat of summer comes many unwelcomed pests, including mosquitoes, ants, fruit flies, wasps and stink bugs, into outdoor spaces and homes.
