A persistent upper-level trough over the Pacific Northwest and western
Canada will remain the focal point for unsettled weather across the
northwestern states through Thursday evening. A series of upper level
disturbances will bring repeated rounds of valley rain and mountain snow
across Washington, Oregon, Idaho, and western Montana. Falling
temperatures will low snow levels across the Cascades and northern
Rockies, producing accumulations at  mountain pass levels that will create
slick roads and difficult travel conditions. Meanwhile, quiet, seasonable,
and dry weather will dominate the Great Basin, California, and the
Southwest before moisture begins to increase late Thursday.

Along the Southeast and Florida Atlantic coasts, strong high pressure
ridging down the Eastern Seaboard interacting low pressure near the
Bahamas will maintain a tight pressure gradient stiff onshore winds. In
combination with high astronomical tides, this setup will drive prolonged
coastal flooding, significant beach erosion, and dangerous rip currents
through Wednesday before winds and marine conditions gradually ease late
Thursday. Persistent onshore winds will also carry isolated to scattered
showers across the Florida Peninsula and coastal Georgia. Further inland
across the Southeast, Deep South, and Tennessee Valley, dry air and breezy
conditions will sustain elevated fire danger.

Across the central U.S., broad southwesterly flow aloft will pump
unseasonably warm air into the region through Thursday. Temperatures are
forecast to run 10 to 20 degrees above seasonal averages from the Central
and Northern Plains through the Upper Midwest and Great Lakes, approaching
record warmth by Wednesday afternoon. A weak surface low and trailing cold
front tracking across the Upper Midwest Wednesday night into early
Thursday will trigger scattered showers and a few thunderstorms from
Minnesota and Iowa into Wisconsin and Michigan. Across the Southern Plains
and Southwest, tranquil weather will hold until Thursday afternoon and
evening, when initial moisture from the remnants of Vance begins spreading
showers into west and south Texas.
