Severe storm threat for over 40 million Americans from Colorado to Georgia

More than 40 million Americans are on alert for possible severe storms that may bring isolated tornadoes.

Americans from Denver and Dallas to Columbus may experience damaging winds up to 70 mph and large hail more than 2 inches in diameter, according to meteorologists.

That severe weather chance is all due to a strengthening low-pressure system that moved across the Heartland on Sunday morning. As that storm pushes east, it will bring rain chances for much of the East Coast on Sunday and throughout Monday, meteorologists said.

That storm would also end any remaining wildfire smoke in the air across the eastern U.S., meteorologists said. There still may be some hazy skies Sunday and Monday, but once that storm moves by, the smoke will also head out.

Storms are already active in parts of the country and will continue through the late-night hours, especially in Alabama and Georgia, where a line of severe storms will likely move out of Tennessee after 9 p.m. ET and continue its push south, meteorologists reports said.

On Monday, severe storms are possible from central Texas to the Florida Panhandle.

Moderate to large hail and damaging winds are forecast for some storms up the East Coast, meteorologists said.

Philadelphia and New York City are not expected to get much rain on Sunday until thunderstorms move in late in the afternoon and into the evening hours, according to meteorologists.

Parts of central and southern Texas are forecast to feel the heat this upcoming week, with temperatures hitting record highs in the upper 90s and lower 100s. The feels-like temperatures will be between 100 to 115 degrees throughout the week, according to meteorologists.

Meteorologists warned that the extreme heat could adversely impact people’s health.

The rising heat brings an increased risk of wildfires across the southwest, according to meteorologists.

A red flag warning is in effect for much of southern New Mexico and the combination of dry heat and gusty winds will keep the critical fire danger in the area through Sunday and into the work week.
