Summer officially started on Sunday and now summertime heat is becoming common place across much of the nation. For the past week the heat has been confined to the South and now it will be spreading northward into the Mississippi Valley the Plains and Texas.
Temperatures will be rising well into the 90s and even into the 100s for much of this week. The heat in addition to high humidity is prompting the National Weather Service to issue excessive heat warnings and heat advisories for many in the Mississippi and Missouri River Valleys.
This heat is a direct result of a large dome of high pressure across the southern and central U.S. Along the fringe of the dome has been waves of thunderstorms. With the ridge building northwestward the main focus of storms is across the Northern Plains and Upper Midwest.
However, there will also be some storms from the southern OH Valley into the Carolinas as the northeastern edge of the dome is being squeezed southwestward due to a trough over the Northeast. This trough is also keeping New England cool.
