...Rain and high-elevation snow expected across portions of the Northwest
and northern Rockies through Wednesday...

...Additional showers and thunderstorms may bring excessive rainfall
threats across east-central and southeast Florida into Wednesday...


An upper-level trough progressing eastward across the Pacific Northwest
will support and eastward moving frontal system across the northern Great
Basin into the northern/central Plains through Wednesday. Broad cyclonic
flow aloft will promote periods of rain and high-elevation snow along the
boundary across the Northwest and Intermountain West, as the cooler air
filters behind the front. Farther east, low pressure tracking from the
central High Plains towards the Upper Mississippi Valley will support
additional rainfall along the frontal boundary across portions of the the
Plains into Upper Mississippi Valley through Wednesday, while wet snow may
develop across parts of the northern Plains through Tuesday morning.

Across the southern High Plains, a dryline and residual low-level moisture
will support scattered showers and thunderstorms through Tuesday.
Meanwhile, persistent easterly flow from the Gulf will continue to
transport moisture into eastern Texas and portions of western Gulf Coast,
favoring periods of showers and thunderstorms. Further southeast, a
slow-moving front and surface trough will support additional showers and
thunderstorms along the Florida east coast and across the Florida Keys as
moisture continues to stream onshore. High rainfall rates may lead to
flash flooding across east-central and southeast Florida through
Wednesday.
