A stormy weather pattern will shift focus to the eastern third of the country on Monday, while a ridge of high pressure builds over the Great Basin.
A low pressure system will move across southeast Canada and the upper Great Lakes. A cold frontal boundary associated with this system will extend south southwestward over the Ohio Valley, the Tennessee Valley, the lower Mississippi Valley and the southern Plains. As this frontal boundary transitions eastward, it will collide with a warm and humid air mass streaming northward from the Gulf of Mexico. This interaction will produce showers and thunderstorms across New England, the Mid-Atlantic, the Midwest, the Southeast and parts of the southern Plains. Prolonged heavy rain will bring threats of flash flooding to southwest Texas. Rainfall totals will range between 2 to 4 inches, with locally higher amounts possible. A cool and dry air mass will trail the frontal boundary and settle in over portions of the northern Plains, the Midwest and the Northeast.
Meanwhile, a ridge of high pressure will continue to build over the Great Basin. This high pressure system will produce offshore winds over parts of California. Low humidity values will elevate coastal temperatures, and will also raise wildfire danger across the state. Heat advisories will remain in effect for portions of the San Francisco Bay Area. In addition, red flag warnings will stay in place for southwest California on Monday.
