updated aviation portion for 18z TAF issuance
and new information added to update section

Update
Issued at 1026 am cst Wed jan 23 2019
it took a while, but the storm got its act together, with an
impressive frontogenetic band producing up to 2 inch hour
snowfall rates over the fox valley and lakeshore areas this
morning. This band was shifting steadily east, and should clear
the lakeshore counties by midday. Accumulating snow is expected
to linger over door county through mid-afternoon, with 1-2 inches
possible after noon, so have extended the advisory there until 3
pm.

Several locations in the fox valley and lakeshore areas will
likely top 6 inches for storm totals (since yesterday), with
local 7-8 inch accumulations.

Short term Today... Tonight... And Thursday
issued at 243 am cst Wed jan 23 2019
the main focus in the short-term will be the potential for light to
moderate snow today, especially this morning into the early
afternoon hours. This will likely lead to snow covered roads and a
slippery morning commute across mainly east-central and far
northeast wisconsin. No changes made to headlines, outside of
updating snowfall totals.

Wv imagery shows the main upper-level low over central ia this
morning as it shifts slowly to the east and northeast. IR shows
extensive cloud cover across much of wi south and west into ia and
mo. Radar shows a broad shield of precipitation lifting
northeastward toward the area with some heavier snow bands lifting
toward the southeast portion of the cwa. At least moderate snow is
falling under these bands with visibility dropping down to around a
mile at times.

Today: low pressure over central illinois is progged to lift
northeastward to lake huron by 21z this afternoon. Aloft, the upper-
level trough will shift from iowa to northern lower michigan through
the same time period. These features being staggered will likely
lead to surface low intensification throughout the day. The
intensifying surface low and increased wrap-around moisture, should
allow snow to finally arrive this morning after being significantly
delayed, to say the least. Thermal profiles continue to show an
elevated dgz, around 12-15kft, which may cut back on snow to liquid
ratios to some extent; however, the snow may become a bit
drier fluffier by late morning or early afternoon as colder air
arrives aloft. This would effectively lower the dgz and allow more
of the moisture to reside in the dgz. It will be somewhat of a
balancing act because the better forcing is expected to begin
departing around the same time. Models are still showing an fgen
band across mainly east-central wi, which may help to bump up
snowfall intensities early in the day. Models are painting out
around 0.15 to 0.25 inches of QPF in this band, which would equate
to roughly 2 to as much as 5 inches of snow through early this
afternoon. Some blowing snow will be possible as well; however, the
low is intensifying as it pulls away, so the most likely area to see
blowing snow will be closer to the shoreline.

Tonight into Thursday: a brief surface ridge and drier air will
slide into the area this evening allowing any snowfall to diminish
from west to east. Again, this will be short-lived as the next
surface trough cold front is expected to slide across the
u.S. Canadian border late tonight into early Thursday afternoon. The
system looks to be moisture starved with only a couple hundreths qpf
expected with this system. This would give most places a dusting to
a half inch of snow, with the best chances of this happening closer
to the upper michigan border. The snow will steadily diminish from
west to east by late afternoon into the evening hours.

Long term Thursday night through Tuesday
issued at 243 am cst Wed jan 23 2019
an arctic airmass will invade the western great lakes region late
this week as 850 mb temperatures plummet into the middle to upper
20s below zero. Low temperatures will plummet to around 20 below
zero across the north Thursday and Friday night, in the middle
teens below zero across central wisconsin and lows of 10 to 15
below across east-central wisconsin. This will cause wind chills
to fall to 25 to 40 below zero during this period, which will
likely necessitate wind chill headlines. The air will be cold
enough that high temperatures on Friday will be below zero across
much of the area, with a few lucky locations possibly breaking
into positive territory during the afternoon hours. Saturday will
be a bit warmer as most locations break into positive territory,
however highs will still only be in the single digits above zero.

Although most locations will be dry during this period, les will
continue across far north- central wisconsin through Friday night.

Temperatures will moderate a bit late in the weekend and
especially early next week, however temperatures will still be a
good 10 to 15 degrees below normal for this time of year. By
Saturday night overnight lows will warm to around 10 below zero,
with wind chills will still 20 to 30 below zero. In addition a
clipper system will pass to the south Sunday night and Monday,
bringing several inches of accumulating snow to the western great
lakes. The latest model runs have taken this system a bit further
south, which would lower snow totals a bit. If this trend
continues the region may not see much snow from this system. If it
does pan out, the highest snowfall amounts look to be across
central and east-central wisconsin which will be where the best
forcing and moisture coincide across our area which would impact
the Monday morning commute.

Dry weather is expected for much of the area behind the departing
low on Tuesday, save for the lake superior snowbelt region of
north-central wisconsin where northerly winds will bring les to
the usual areas. Temperatures behind the system will also stay a
good 15 to 20 degrees below normal for this time of year.

Aviation For 18z TAF issuance
issued at 1026 am cst Wed jan 23 2019
steady snows will taper off from west to east during the early
to mid afternoon, with conditions improving toVFR local MVFR at
most locations later in the afternoon and evening. Another round
of light snow is expected to overspread the region from west to
east late tonight into Thursday morning, along with a return to
MVFR ifr flight conditions.
