weak clipper system will move through tonight into early sunday
morning bringing another shot of light snow. a more of a f-gen
band set up will bring a fairly narrow band of snow over the
area, some uncertainty to exactly where the band sets up but
either west or east of the band will see minimal amounts if any
snowfall. current thinking is that mainly the western half of
the cwa would be in line for the higher accumulations which will
top at at around an inch to inch and a half. colder air behind
this system will bring cold overnight lows with single digits
for the eastern half of the cwa where better chances for some
clearing of the skies. temps will only drop to right around the
mid teens for the western half with more cloud cover and the warmer
plume from the lake modified airmass. highs on sunday only in
the low to mid 20s within the northwesterly flow behind the
system. similar low temperatures to sunday morning will also be
in place on monday morning.
ridging in place over the western conus will begin to move
eastward and will begin to see synoptic warming arrive which
will allow for a warming trend for the first half of the week.
highs on tuesday will approach the low 40s. of course, some of
the warming will be offset with the snowpack still in place. a
more zonal flow sets up aloft over the region by wednesday into
the end of the week which will allow near to above normal
temperatures remain in place through the work week with highs
mainly in the low to mid 30s. a weak disturbance move through
the region late tuesday into wednesday and could bring a
rain/snow mix as most of the energy skirts to the north of the
area. otherwise, a couple of weak disturbances rippling through
the northern periphery of the zonal flow could bring some light
snow showers for the second half of the week. a few drops of
rain may mix in especially during the daytime but kept just the
mention of snow showers at this time. will evaluate as we get
closer.
another clipper system looks to move through on friday and again
bring another shot of light snowfall.

vfr conditions to dominate through at least the first half or so
of the period as nw flow slow weakens and becomes light and
variable in advance of another fast moving wave set to arrive
late tonight. moisture quite limited with this feature, but
enough forcing to warrant at least some mvfr vsbys with lighter
snowshowers. as mentioned in the previous discussion, if flake
size is smaller a great vsby impact could occur than presently
forecasted. the period of light snow appears to be confined to a
3 to 5 hour window with a se wind then dominating thereafter.
