A well defined low pressure area over the Central U.S. continues to advance eastward this morning. Ahead of the trailing cold front, showers and thunderstorms capable of scattered heavy rainfall and some severe weather will spread eastward into the Middle and Lower Mississippi Valley, while a steady rain falls over the Northern Plains and Upper Midwest today. By Thursday, the front will reach the Northeast and Mid-Atlantic, ending the recent stretch of dry weather in the region. Meanwhile, persistent easterly onshore flow south of a large high pressure cell will maintain the threat of heavy rainfall for at least another day over southeast Florida. Additional rainfall could exacerbate problems from the impactful flooding that occurred yesterday, and Flood Watches remain in effect for the area. In the West, an approaching Pacific frontal system will usher in modest rainfall to North-Central California today. The upper-low associated with this system could eventually lead to some mountain snowfall tomorrow and Thursday over the Central Rockies. Cooler than average temperatures will linger over portions of the High Plains and West this week. In contrast, unseasonably mild weather will prevail for much of the East this week as the trailing cold front modifies over the next few days.
