...Very heavy snow possible over the Sierras...
...Heavy snow possible over parts of the Great Basin and Central/Southern
Rockies...
...Heavy lake effect snow downwind from Lake Ontario
...Heavy rain possible over the Central California Coast...
An upper-level low over the Pacific Northwest will slowly weaken and move
to parts of the Great Basin by Thursday evening. Onshore wind will drive
a plume of moisture into Central/Southern California also through
Thursday. The system will produce rain and snow from California/Oregon
eastward to the Northern/Central Rockies that will end over the Northern
Rockies/Oregon by Thursday morning. The rain and snow will end over parts
of Northern California by Thursday evening while rain and snow will move
into parts of the Southwest and Southern Rockies. In addition, the rain
will be heavy at times over the Central California Coast. Likewise, the
snow will be very heavy over the Sierras.
Meanwhile, upper-level energy over Central Canada will move southeastward
to the Middle Mississippi Valley by Thursday evening. The energy will
trigger snow over parts of the Central Plains on Wednesday that will
expand into the Middle Mississippi Valley/Ohio Valley on Thursday.
Additionally, upper-level energy over the Upper Great Lakes will move into
Southeastern Canada by Thursday. The system will produce rain and snow
over parts of the Ohio Valley and Central/Northern Appalachian as well as
parts of New England that will end over the Central Appalachians by
Wednesday evening. In the meantime, cold air will move over the Great
Lakes producing lake effect snow downwind from the lakes. The low-level
flow will aid in producing heavy snow downwind from Lake Ontario.
Elsewhere, developing low pressure along the Southeast Coast will aid in
producing rain over parts of the Southeast Coast by Thursday evening.
