The stormy weather pattern that has affected much of the United States shows "no signs of abating over the next couple of days as we head into the weekend," according to the National Weather Service on Thursday.

Sodden California, which has already experienced significant storms this week, including two tornadoes and a bomb cyclone, received additional snow and rain on Thursday.

A storm is also expected to move across the country's southern tier later Thursday and into Friday, potentially causing flooding and the threat of additional tornadoes in some areas on both days.

Some areas may receive up to 5 inches of rain. The weather service warned that excessive runoff could cause flooding in rivers and streams and that people who live in flood-prone areas should be "prepared to take action."

While crews continue to repair roads and restore power to many parts of the Bay Area, forecasters predict a cold front will arrive this weekend, followed by at least a couple days of wind and rain, as per NBC.

While Thursday and Friday appear to be mostly clear of severe weather, temperatures will be colder than normal overnight Friday into Saturday morning, with frost expected in the North Bay as well as south in Monterey and San Benito counties.

According to the National Weather Service, this will happen again overnight into Sunday morning and evening, with the South Bay joining the frosty mix.

Wind and rain are expected to blanket the entire Bay Area on Monday and Tuesday.

The Risk Of Severe Storms Is Increasing In The South

People in the southern United States should pay close attention to weather forecasts over the next few days, as severe storms appear to be on the way, as per FOX News.

The southern Plains across Texas and Oklahoma face the greatest risk of severe weather on Thursday. On Friday, the highest risk is in parts of Louisiana, Arkansas, and Mississippi in the Deep South.

Tornadoes aren't something you hear about very often in the Los Angeles area. An EF-1 twister that hit the area on Wednesday, however, caused damage and injured at least one person.

As the cyclone passed through Montebello, California, debris was seen swirling in the air. One witness described seeing a funnel cloud before falling debris.

The National Weather Service issued a flood watch from Oklahoma to Pennsylvania on Thursday due to a forecast of rain and thunderstorms. As of late Thursday afternoon, a flood watch was in effect for over 22 million people.

Governor Jim Justice of flood-prone West Virginia declared a "state of preparedness" for the state's 55 counties on Thursday due to the heavy rain threat.

According to the weather service, the storms will "become a significant concern" later Thursday and continue through Friday for parts of the southern Plains, Mississippi Valley, and the South.

Storms in the South could also become severe in the coming days. Through Thursday evening, the National Weather Service has issued severe thunderstorm warnings for parts of Arkansas, Missouri, Oklahoma, and Texas, as per USA Today.

According to AccuWeather meteorologists, the threat of severe weather intensifies and expands on Friday, with areas from Houston to Cincinnati bracing for strong to severe thunderstorms.

Storms could produce "strong tornadoes," as well as damaging winds and large hail, according to the Storm Prediction Center. On Friday, portions of Arkansas, Mississippi, and Louisiana are in the highest risk zone.
