NWS Weather Forecast: Severe Storm Heads to Northeast, Extreme Heat to Continue Until Next Week

Severe thunderstorms are on its way into the Northeast by passing through the Ohio Valley into Upstate New York, causing potential tornadoes, damaging winds, and large hail, according to the National Weather Service (NWS).

The occurrence of heavy rain flooding is possible in the coming hours and days.

The NWS weather forecast also mentioned excessive heat in the Central Mississippi Valley and southern Arizona that is expected to spread from the Northern Great Plains to the Southeast.

The intense heat poses life-threatening risks for both animals and humans, as well as power lines.

The forecast comes after a major flooding due to heavy rainfall and rapid snowmelt submerged the Yellowstone National Park early this week and forced the State of Montana to declare a state of emergency.

Furthermore, it follows the Kansas heat wave responsible for killing thousands of fat cattle.

Lastly, severe storms recently caused widespread power outages across the Midwest, leaving over 600,000 customers without power supply over recent days.
