Heavy rains continued across Texas on Saturday, while showers and thunderstorms moved into the Carolinas.

A low pressure system strengthened as it moved over Texas and spread tropical moisture across the state. At the same time, the system pulled moisture in from the Gulf of Mexico, which kicked up heavy rainfall across most of central and northern Texas.

The system moved eastward throughout the day and approached the Lower Mississippi River Valley. Heaviest rainfall was reported in Abilene, Texas, with a midday total of 3.84 inches of rain. Thus, flash flood advisories were issues throughout the region. Strong winds also accompanied this strong low pressure system with gusts from 40 to 50 mph across parts of Texas and the Lower Mississippi River Valley.

Meanwhile to the east, a low pressure system over the Northeast pulled northeastward and into far eastern Canada. The system pushed a cold front offshore, which allowed for showers and thunderstorms to diminish across New England.

However, rain showers persisted for parts of Maine, as well as along the southern side of the front as it moved into the Carolinas and the Southeast. Heaviest rainfall associated with this frontal boundary was reported in Burlington, N.C. with a midday total of 1.17 inches of rain. This system has a history of producing strong and damaging winds, but severe storms have not developed.

In the West, a cold front dropped into the Pacific Northwest from British Columbia and brought cooler temperatures and partly cloudy skies. High pressure built over the rest of the West Coast and created a hot and dry day. Fire danger increased for most of California.
