...Light rain to continue over the Northeast through Monday morning...
...Rain and snow are likely across much of the West through Monday...
...Fire danger is expected to continue in the southwestern quadrant of the
U.S. for the next few days...
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. The
Critical risk will continue over parts of the Southern Rockies into the
Southern High Plains on Monday into Tuesday morning. Red Flag Warnings
are also in effect from parts of the Great Basin/Southwest to the
Southern/Central High Plains.
