More severe weather will persist Tuesday across the Eastern U.S. as a low pressure system continues making its way through the nation.
The system will push a warm front through New England and into the Northeast, while a cold front will extend south of this system, sweeping through the Gulf states. In between these two frontal boundaries, warm and moist air will pour in from the Gulf of Mexico, creating warm and humid conditions across the Southeast and Mid-Atlantic states. These conditions will be favorable for severe storms development. This system has a history of producing strong and dangerous winds, large hail and even tornadoes. If storms turn severe, they will most likely develop across the Southeast. Rainfall totals will vary between 2 and 3 inches in areas of severe storms, while most of the Midwest and Ohio River Valley will see around an inch of rain. Thus, flooding will remain of concern across the Ohio and Mississippi River Valley as the already soaked ground will see more heavy rains.
Meanwhile, to the west, a low pressure system that brought rain to the West Coast will continue moving eastward and over the Rocky Mountains. Precipitation from this system will turn to snow as it moves over the Rockies. Snowfall accumulation across the Northern and Central Rockies will range around 1 to 2 inches. As this system moves east, the West Coast will dry out due to a building ridge of high pressure. A few light showers may persist over the Pacific Northwest, but most of California will be drier with a few patchy clouds.
Temperatures in the Lower 48 states Monday ranged from a morning low of 8 degrees at Yellowstone, Wyo., to a high of 97 degrees at Laredo, Texas.
