evening, particularly across the northern half of the lake. Small
Craft Advisory conditions are likely during this period across the
nearshore waters. The southwest winds will then gradually lessen
from late Friday night through the weekend.

Freezing spray is likely in the south today and across the lake
tonight into Friday morning.

PREV DISCUSSION... (Issued 523 AM CST Thu Feb 20 2020)

UPDATE...
No changes to current forecast.

AVIATION(12Z TAFS)...
VFR conditions expected to continue through the TAF period with
clears skies and light winds from the west/northwest. Into Friday
morning winds will turn to the southwest and become a bit breezy
into the afternoon and evening.

PREV DISCUSSION... (Issued 235 AM CST THU FEB 20 2020)

SHORT TERM...

TODAY THROUGH FRIDAY - Forecast Confidence...High.

With very strong high pressure centered just to the west and clear
skies across southern Wisconsin temperatures will be fairly chilly,
especially early this morning. Temperatures this morning will be in
the negative single digits across much of the area with wind chills
in the negative teens. Temperatures will not warm up too much during
the day today either despite clear skies.

Tonight temperatures will not likely fall as much with temperatures
reaching the low to mid single digits as the strong high pressure
weakens somewhat as it pushes to the south. This will increase the
pressure gradient across the region with winds strengthening from
the southwest into the day Friday. This will also rapidly increase
temperatures to the 30s Friday.

FRIDAY NIGHT AND SATURDAY - Forecast Confidence...High.

Southwest breezes will diminish Friday night due to upstream weak
troffing across the northern Plains weakening the pressure gradient
across the western Great Lakes. Milder air however will remain in
place with 925H temps in the 0 to 3C range.  With sunshine and dry
southwest winds, daytime temps should rise into the upper 30s to mid
40s across southern WI on Saturday.  Melting of snow will be in full
force during the day, especially in southeast CWA, where snowfield
is around or less than 3" across most of the area.

LONG TERM...

SATURDAY NIGHT THROUGH WEDNESDAY - Forecast Confidence...Low to
Medium.

Zonal steering flow at the onset of this period will ensure milder
air remains in place through the later half of the weekend.  Daytime
temps should easily rise into the 40s.  However need to be careful
of potential fog development Sunday morning due to melting snow
adding moisture to low levels and diminishing low level winds. Any
fog that develops should be shallow and burn off, so wl continue
optimistic temp forecast for Sunday.  Mid-high level clouds may
spread across the area as southern Plains low pressure takes a turn
to the northeast.

Cutoff low pressure in the southwest early in the period will get
nudged eastward into the central/southern Plains by Sunday night.
Extended guidance in reasonable agreement on this scenario, with
upstream short-wave beginning to carve out trof in northern stream.
However same Extended guidance having issues resolving timing and
track of Plains low pressure as it moves to the northeast early next
week. Both 00Z GFS and ECMWF slow down northeastward progress of
low, but some GEFS ensembles continue to bring QPF into southern WI
Sunday night. Considerable dry air in place across the Great Lakes
ahead of this system, which will also slow down northward progress
of precipitation.  Never the less, with upstream amplifying trof,
would think this system would take a more northeast track and return
precipitation to southern WI in the Monday/Monday night time frame.
For now, worthwhile to continue chance pops for much of the period,
even into Wednesday, due to potential lingering low pressure trof in
the area.  Confidence higher on colder temperatures returning in the
wake of this system due to long-wave trof amplification across the
central CONUS.

AVIATION(09Z TAF UPDATE)...

VFR conditions through the TAF period with clear skies and mostly
light winds. Winds will pick up from the southwest into Friday,
however.

MARINE...

Conditions remain quiet over the lake today and tonight with strong
high pressure dominating the region. Into Friday, however, the high
will push to the south bringing a stronger pressure gradient across
the lake. This will likely bring gale force gusts across the
northern half of the lake by Friday afternoon and extending
southward across a majority of the lake by Friday evening. Thus a
Gale Watch remains in effect for the northern half but has been
extended to the southern half of the lake as well from 18z Friday to
6z Saturday. A Small Craft Advisory will also likely be needed for a
period as well.

Overnight Friday, winds will decrease to below gales but will remain
modest and predominantly from the southwest through Sunday prior to
another system pushing east to the south of the lake.
Winds are not expected to be a concern through at least early next
week.
