...Heavy snow possible over the Sierras...
...Heavy snow possible in downwind favored areas from the Great Lakes...
...Rain/freezing rain possible over interior portions of the Pacific
Northwest/Northern California...
...Temperatures will be 15 to 35 degrees below average over the
Northern/Central Rockies and High Plains...
Deep low pressure just north of the Great Lakes will slowly move
northeastward to just east of James Bay by Thursday evening. The energy
will produce snow over parts of the Northern Plains to the Upper Great
Lakes through Thursday with the snow ending over the Northern Plains and
the Upper Mississippi Valley on Thursday afternoon into evening. The
associated upper-level low will pass just north of the Keweenaw Peninsula
on Wednesday that will aid in producing the heaviest snow over that region
of the Great Lakes. The lake effect/enhanced snow will move into the
Lower Great Lakes on Thursday morning into evening. In addition, a front
extending from the Lower Great Lakes/Northern Appalachians southward to
the Southeast will move eastward off the East Coast by Thursday morning.
Higher elevation snow and rain will develop over parts of the Central
Appalachians/Lower Great Lakes eastward to the Northeast/Northern
Mid-Atlantic that will slowly wind down west to east overnight Wednesday.
Meanwhile, upper-level energy over the Great Basin/Central Rockies will
move eastward to the Northeast by Thursday evening. The energy will aid
in producing snow over parts of the Great Basin into parts of the Central
High Plains on Wednesday morning ending by Wednesday evening. Upper-level
jet dynamics will aid in producing rain over parts of the Western Gulf
Coast starting overnight Wednesday that will expand into the Lower
Mississippi Valley and Southern Plains on Thursday retreating to the
southern tip of Texas by Thursday evening. Furthermore, a boundary moving
over Southern Florida will aid in producing showers and thunderstorms over
the region Wednesday morning into Thursday evening.
Elsewhere, a front over the Eastern Pacific will approach the West Coast
Wednesday into Thursday. A plume of moisture associated with the system
will begin to move onshore over California on late Wednesday morning,
expanding into parts of the Pacific Northwest on overnight Wednesday into
Thursday. Rain and higher elevation snow will develop over
Central/Northern California by Wednesday evening. The snow will expand
eastward into parts of the Great Basin/Northern Intermountain Region by
Thursday evening. Rain and higher elevation snow will move into parts of
the Pacific Northwest early Thursday morning expanding northward into
Washington State on Thursday afternoon into evening. Additionally, rain
and freezing rain will develop over interior parts of Northern
California/Pacific Northwest on Thursday morning into evening.
