Heavy rain remains possible along the Central Gulf Coast on Monday, while scattered showers continue in parts of the East. Sufficient moisture will remain over the southeastern quadrant of the nation as a nearly stationary front lingers from the Central Gulf Coast through the southeastern corner of the nation. Showers and thunderstorms will remain likely along the Central Gulf Coast from the Florida panhandle through southern Mississippi. Stronger storms in the region will be capable of producing locally heavy rainfall, strong wind gusts and lightning. Heavy rainfall combine with recent heavy rains during the weekend, will maintain threats of flooding. Rivers mainly in the Florida Panhandle and extreme southern Alabama are expected to remain at action stage or experience minor flooding. In addition to rain and thunderstorms, a moderate risk of rip currents are expected for these coastal areas on Monday. Outside of this area, generally light, scattered showers and chances of thunderstorms are expected through the Tennessee Valley into the southeastern Ohio Valley and Mid-Atlantic.
Meanwhile in the North, a cold front moving eastward across the north-central U.S. will linger over the region, supporting showers and chances of thunderstorms from the Northern Plains into northern Minnesota and northern Wisconsin.
Out West, monsoonal moisture lingering over the Four Corners will maintain chances of afternoon and evening shower and thunderstorm activity. Meanwhile, low pressure located near the central California coast will produce thunderstorm chances through the beginning of the week. Thunderstorms may produce dry lightning at first but are expected to pick up moisture over time. Dry fuels over the region may allow fires to start with storms accompanied by rain.
