The nation's weather

Active weather will persist across the nation Thursday, as one low pressure system moves over the East Coast and another moves into the Plains.

The system that brought heavy rains, hail and strong winds to the Mid-Mississippi River will continue moving eastward, over the Eastern Valleys and over the East Coast. A front associated with this system will stretch from the Northeast into the Southeast, where it will trigger scattered showers and thunderstorms with a slight risk of turning severe. Expect rainfall totals ranging around an inch.

Meanwhile, another low pressure system moves off the Rockies and into the Central Plains. The leading edge of the system pulls moisture in from the Gulf of Mexico and allows for scattered showers and thunderstorms to develop from North Dakota to Texas. The most likely areas of severe storms are confined to Nebraska and Kansas, as well as along a cold front that stretches into Texas. Hail, strong winds and heavy downpours are likely, with a few tornadoes possible. The Mid-Mississippi River and Missouri River will remain under flood advisories due to these repetitive storm systems bringing multiple rain showers to the region.

Out West, fires will remain of concern across Arizona and New Mexico as a ridge of high pressure allows for more hot, dry and windy surface conditions. Just to the north, a trough dips into the Intermountain West and Northern Rockies from British Colombia, triggering scattered showers throughout the day.

Temperatures in the Lower 48 states Wednesday ranged from a morning low of 27 degrees at Stanley, Idaho, to a high of 105 degrees at Laredo, Texas.
