Storms were predicted across the Central and Northern Plains, as a low pressure system collides with moist air from the Gulf. This will result in a widespread area of heavy rain and thunderstorms across the already flood-stricken Central Plains.
In addition, large hail, damaging winds and tornadoes were possible, especially over eastern Nebraska into north-central Kansas.
Moving east, the Northeast and Mid-Atlantic should cool off significantly. The Upper Great Lakes could possibly see some showers and thunderstorms. Temperatures should be in the 80s for both regions.
Afternoon and evening showers and thunderstorms were expected through Thursday over the Southeast and parts of the Gulf Coast.
The Northwest will see a significant warming trend on Wednesday as a strong low pressure system begins to depart from the area. The region should see partly sunny skies as a few clouds from the storm linger throughout the day.
The Southwest will be slightly cooler on Wednesday. Temperatures are expected to drop to the 80s and 90s, although some areas to the far south could still reach 100 degrees.
Temperatures in the Lower 48 states on Tuesday ranged from a low of 21 degrees at Mullan Pass, Idaho, to a high of 108 degrees at Blythe, Calif.
