An upper-level low over the Northern Plains will weaken and move slowly to Lake Superior by Thursday. Showers and thunderstorms will develop along and ahead of the associated boundary from the Upper Midwest to the Southern Plains. Likewise, the showers and thunderstorms will advance slowly eastward to the Lower Great Lakes to the Tennessee Valley to parts of the Southern Plains by Thursday. Rain will also develop over the Northern High Plains on Tuesday evening and move to the Northern Plains/Upper Mississippi Valley on Wednesday evening. Meanwhile, another upper-level low over Northwestern Mexico will slowly move eastward to the Lower Rio Grande Valley by Thursday. Circulation around the upper-level low will aid in streaming moisture from the Gulf of Mexico northward over the Southern Plains through Thursday morning. The moisture and the energy will aid in producing showers and thunderstorms over parts of the Central/Southern High Plains and the Southern Plains through Thursday. In addition, daytime heating and moisture rich air over the Lower Mississippi Valley eastward to the Southeast will aid in developing showers and thunderstorms with a maximum areal coverage during the late afternoon into the evening hours on Tuesday into Wednesday. Furthermore, Post-Tropical Cyclone Bonnie will spin along the Carolina Coast through Thursday. Showers and thunderstorms will develop along the Carolina Coast Tuesday into Thursday. Additionally, tropical moisture associated with Bonnie will extend well into the Mid-Atlantic. The moisture and daytime heating will aid in producing afternoon and evening showers and thunderstorms over parts of the Mid-Atlantic through Thursday. Elsewhere, a plume of moisture from the Pacific will begin to stream into parts of the Pacific Northwest producing rain over parts of the Northwest Coast Wednesday evening into Thursday.
