Stormy Weather and Scorching Heat Ahead: July 8th - July 10th, 2025
Updated Tue Jul 8th 2025, 9:22am PDT

Get ready for a mix of storms and heat waves in the coming days! We're tracking thunderstorms in the Arklatex region and the Midwest today and keeping an eye on possible severe weather in the Mid-Atlantic with heavy rain expected up to southern New England. By Wednesday, more rain and storms could hit the Mid-Atlantic, and strong thunderstorms are likely to move across the northern Plains into Thursday morning. Plus, watch out for major heat risks across much of the East and triple-digit temperatures in the Northwest and Desert Southwest. Let's dive into the details!

Stormy Weather for the South

A high pressure ridge is weakening across the southern Plains, causing scattered thunderstorms to kick up in the Arklatex region today. While these storms may offer a welcome break to parts of flood-stricken Texas, they could still bring heavy downpours this afternoon and evening as they move eastward. Expect these storms to calm down tonight and flare up again on Wednesday across the Deep South and the southern Appalachians.

Severe Weather Alert for the East Coast

The Mid-Atlantic is in for a potentially stormy afternoon and evening with the risk of severe thunderstorms as a cold front approaches. Temperatures could hit the 90s today, adding fuel to these storms and increasing the chance of heavy rain extending through southern New England. By Wednesday, expect more scattered storms and possible heavy rain in the Mid-Atlantic, which might linger into early Thursday.

Northern Plains and Midwest Get in on the Action

In the central Plains, a batch of strong thunderstorms is moving toward the Midwest today. These storms, linked to a low-pressure system, will continue east through the Great Lakes by tonight and Wednesday. By Wednesday night, heavy downpours could develop in the northern Plains as a warm front lifts and another low-pressure system takes shape.

Get Ready for the Heat

Heat is gripping much of the country! Temperatures will soar across the Southwest, Great Basin, and the Rockies, pushing into the High Plains. California, Arizona, and Nevada are bracing for highs over 110°F. As a strong front moves into the Northwest by Wednesday, the heat will shift eastward into the northern High Plains, with highs in the upper 90s and low 100s. Meanwhile, the eastern part of the country, from Atlanta to Boston, will also experience major heat today. However, slightly cooler temperatures are expected later in the week, easing heat risks in these areas.
