More California storms and rain in the Southwest

Tom Moore, Sr. Meteorologist, The Weather Channel




A persistent and relentless storm system continues to send in waves of pounding rain into Southern California and this trend will continue on Tuesday. To make matters worse, severe thunderstorms erupted in the Los Angeles and Sacramento areas on Monday. Two weak tornadoes touched down northwest of Sacramento. The thunderstorm threat will continue through Tuesday. The threat of floods and mudslides will persist, too. Look for heavy snow, especially in higher elevations above 6000 feet. Meanwhile, showers will spread eastward, covering much of Nevada, Utah, Colorado, Arizona and New Mexico. Heavy snow is likely in the mountains of northern Arizona, Utah, and southwest Colorado and northern New Mexico through at least Thursday. Bone dry conditions will persist from Washington and Oregon to Montana and much of Wyoming. High temperatures in the 30s and 40s will dominate the Interior West, with some 60s showing up along the West Coast and in parts of the Desert Southwest.



Severe thunderstorms pounded parts of the Southeast on Monday from northern Mississiippi ans southern Tennessee to South Carolina. Large hail covered the ground in the northern suburbs of Atlanta. The combination of a sagging cold front and plenty of warmth and moisture will allow thunderstorms to erupt again on Tuesday, mainly from central Texas to the extreme western Florida Panhandle. A very wet preiod is in store for these locations over the next few days. High temperatures on Tuesday will be in the mild 70s across the Gulf Coast with a few 80s in extreme southern Texas and over parts of central and southwestern Florida.



Most of the Northeast will enjoy a dry Tuesday, except for a few snow showers across northern Maine. A trough of low pressure will spark snow showers across parts of western New York by Tuesday evening. That system will usher colder air into the region and it will remain chilly for awhile. Look for snow showers downwind of the Great Lakes on Wednesday. High temperatures on Tuesday will be mostly in the 20s and 30s but it will be colder by midweek.



Colder air will push into the upper Midwest and Great Lakes on Tuesday. Snow showers will also be common, especially over parts of Michigan. The rest of the region will dry into Wednesday. The exception on Wednesday will be some rain and snow moving into the central Plains. High temperatures on Tuesday will range from the teens in northern sections of North Dakota and Minnesota to around 50 degrees along the Ohio River.
