Tidbits from Long Term AFD by CLE and IWX...
CLE:
.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
A large upper level ridge over the eastern United states will begin
to amplify slightly by the end of the week as a deep digging upper
level trough dives into the Central Plains states. Surface high
pressure over the Ohio Valley will settle south and build as it
moves out to the Atlantic Ocean from the Georgia coast. Warm air
advection will take place on the west side of the high pressure into
the forecast area for much of the latter half of the week. As the
upper level trough begins to dive into the Plains States toward the
end of the week, a series of surface low pressure systems will
develop over the Oklahoma Panhandle. The first will move northeast
through the central Great Lakes Friday night keeping our area in the
warm sector. However, looking further out, the second Panhandle
Hook appears it will track deeper south and keep the local area on
the cold side of the low. Another possible winter storm will need
to be watched for Sunday as the week progresses. All of the long
range models agree on colder air and development of this low at this
time.
IWX:
Guidance still advertises an active pattern setting up for the
weekend with a storm brewing over the central states. The features
to watch are a cut-off low off the coast of the Baja and a trough
arriving onshore of British Columbia late in the week. These
features will dictate how the storm from the Central U.S. evolves.
Stay tuned!
