Major ridging down south is causing an extreme rise in temperatures across the southeast especially. High temperatures will be in the upper 90s to low 100s with lows only cooling to the upper 70s. Heat indices will be really high so it will be dangerous to be outside for extended periods of time. Texas will also see a lot of these extreme temperatures. Many heat risk warnings are in effect especially in the mainland areas. Coastal areas will be slightly less hot but still hot.

After next week these extreme temperatures will come to a slow down and slightly cool down in the southeast. Meanwhile the southwest and Texas will see some ridging this week and stay hot for an extended period of time with a ridge building late next week. New Mexico, Arizona, Texas, and California will get the heat and temperatures in the 100s in many regions.

Today we will see some storms across the east and plains. The southeast will see some scattered storms and the northeast will see rain in the afternoon with small thunderstorms. In the north central region of the US some rain and scattered showers will hit the Dakotas with some isolated showers in Iowa.

Rain will remain across the central US towards the east and Sunday night heavy rain will fall in the Ohio valley region. Said system will move across the northeast early next week.

Travel Impacts

The northeast, central plains, and midwest could see some rain delays in airports due to rainfall. Traveling near the Dakotas be cautious because of heavy rainfall and flash flooding. Be mindful of hydroplaning on wet roadways and limited visibility. Always check local traffic reports to make sure you avoid unnecessary travel in rainy conditions.
