Low pressure just off the Northeast Coast and a front extending from the Lower Great Lakes to the Ohio Valley will produce light rain across the Northeast that will slowly end on Monday. Light snow will also develop across the higher elevations of the Northeast overnight Sunday that will gradually taper off by Monday evening. In the meantime, a warm front over the Northern/Central Plains will move eastward and lift northward into the Upper Great Lakes by Tuesday. The boundary will aid in producing rain and snow over parts of the Northern Plains/Upper Mississippi Valley on Sunday morning, moving into the Upper Great Lakes overnight Sunday. The rain and snow will change over to all rain over the Upper Mississippi Valley/Upper Great Lakes on Monday, continuing into Tuesday morning. Furthermore, a deep upper-level trough just off the Northwest Coast will move onshore on Sunday, moving to the Great Basin by Tuesday. The energy will aid in producing rain and higher elevation snow over the Pacific Northwest eastward into the Northern High Plains and extending southward to parts of Northern/Central California on Sunday. By Sunday evening, the rain and higher elevation snow will expand into parts of the Great Basin while rain moves into parts of Southern California. Overnight Monday, the rain and higher elevation snow will move into parts of the Southwest. The rain and snow will taper off by Monday morning over the Northwest and most of California. A Critical risk of fire weather will extend across the Southwest to Southern Plains on Sunday, given dry conditions and gusty winds.
