Cold wave pattern to linger across the Heartland
An expansive cold outbreak will further intensify. Sub-zero temperatures will continue through Monday morning across northern sections of the Rockies and High Plains, while readings below 20° may occur early next week as far south as the northern panhandle of Texas.
Meanwhile, another snowfall will affect the North. Snow, initially in the northern Rockies, will spread across the northern Plains on Saturday. By early next week, snow may blanket central and southern parts of the Rockies and High Plains, aiding wildfire containment efforts and benefiting winter wheat.
Farther east, significant rain may occur from the southeastern Plains into the Ohio Valley. Mostly dry weather will persist, however, in California, where the wildfire threat will be substantially elevated on Sunday and Monday.
Elsewhere, a low-pressure system over the western Caribbean Sea will drift northward, with some possibility of development. Regardless of intensity, the system may produce heavy rain in Florida.
Looking ahead, the 6- to 10-day outlook calls for the likelihood of below-normal temperatures across the Rockies, Plains, Midwest, and Northeast, while warmer-than-normal weather will be confined to the Southeast and Far West.
Meanwhile, below-normal precipitation in the upper Midwest and much of the western half of the U.S. should contrast with wetter-than-normal conditions from the southern Plains to the Atlantic Coast.
