As July draws to a close, a storm system swinging up from the Deep South will bring downpours that will break the back of the heat wave in much of the northeastern United States.
Heavy downpours will raise the concern for flash flooding along the Gulf Coast and lower Mississippi Valley through midweek.
A stifling heat wave will remain entrenched across the Northeast much of this week, despite a brief reprieve in humidity for some.
Dangerous heat will surge northward and send temperatures rising across the northwestern United States this week.
Severe thunderstorms rumbled through the Northeast on Monday, lashing the region with damaging winds while also unleashing heavy downpours that triggered flash flooding.
Here are five easy ways to stay cool in sweltering summer heat.
