.update...
issued at 1030 am est sat jan 25 2025
despite slow approach of cold front and decent upper level
energy, precipitation has yet to reach the ground as high cloud
bases (10,000 ft or so) and dry layer below are resisting even
flurries at this point. even if a few flurries manage to make it
to the ground (mainly s of us-30), no accumulation or impacts
would occur, so opted to remove any measurable precip mention.
thinning/clearing of the cloud cover is noted upstream, which
should allow temperatures to warm somewhat, reaching the low to
mid 30s. may need to nudge temps up a few degrees if clearing
and peak heating is able to overcome the cold ground
temperatures from the snow pack.

absolute dearth of viable moisture per 00z soundings upstream
necessitate dropping prior low chc pops for this morning in
conjunction with weak disturbance shearing out through nrn lower
mi. cold front in association with this system drops through
the area late day but until then swrly low level flow/mixing
expect temps to crack freezing this aftn. briefly colder
tomorrow as plains centered ridge builds in.
thereafter area remains entrenched in between active nrn/srn
streams with quiet wx and near seasonable temps. some sign of
change though very late period (next weekend) with development
of a more vigorous and unsettled looking deep sw flow pattern
aloft taking shape across the conus. leading swrn us bowling
ball ejecting out late fri/early sat most notable with
incorporation of some degree of wrn goa moisture influx and
which bears watching. med range model spread is high as expected
and blend offers middle ground solution at this range.
