After a quiet weather start to the month of November, changes will begin on Thursday that will eventually sweep eastward.

The quiet warm, dry weather pattern across the U.S. is about to end, especially across the West as several systems move, bringing widespread rain and mountain snow to the region. 

"Big changes going on here with plenty of rain and mountain snow over the next couple of days," Fox News senior meteorologist Janice Dean said on "Fox & Friends."

Winter weather advisories are up for Friday night across northern California, and a winter weather watch has been issued for the highest elevations in the Sierra Nevada into Saturday. 

Over the Plains, strong winds with the incoming storm system and dry conditions will raise the fire danger.

Red flag warnings are also up for California and Nevada on Thursday due to the gusty conditions.

In areas ahead of the storm system, high temperatures have been 20 to 35 degrees above normal, with some places having the potential of breaking record highs. 

That warm weather will continue to shift east, giving the Midwest and Northeast warm conditions for the weekend.

"The rest of the country, very quiet, very beautiful," Dean said Thursday.

That could change by early next week in Florida when what's left of Tropical Depression Eta may edge close to the southern part of the state.
