Skies are clearing quickly behind this precip across southern wi
tonight. Wind are diminishing quickly as well. Winds aloft will be
light over central wi for a short period of time and then will
increase out of the northwest just off the surface late tonight.
Areas of fog are developing in the area of light winds just west
and northwest of madison, but this will dissipate as winds
Areas of fog are likely west of madison for the next couple of
hours. Then expect the fog to clear and a brief period of low
level wind shear late tonight as northwest winds increase just
above the surface. Winds will become very gusty out of the
northwest by mid morning and diminish later this evening.
Accumulating snow is expected on Saturday. That should spread
into madison by mid morning and milwaukee by late morning. The
axis of heaviest snow looks like it will be along the i-94
corridor and highest snowfall rates should be in the afternoon
hours, perhaps lingering into the early evening.
Prev discussion (issued 944 pm cdt Thu apr 25 2019)
update... Showers continue to progress steadily east. There has
been some redevelopment on the back edge, so still thinking
showers may linger in eastern areas a little longer, ending
between midnight and 2 am or so.
00z NAM remains consistent in track of low pressure and low level
temperature profile across southern wisconsin for Saturday.
Initial light rain snow mix should change to mostly snow as
stronger lift spreads in late morning and afternoon.
Marine... Brief period of gusty north to northwest winds expected
overnight, with a few gusts to 25 knots in the nearshore waters.
Not expecting the gusty winds to last long enough to warrant a
small craft advisory. Tightening pressure gradient associated with
low pressure passing through the eastern great lakes will result
in a more prolonged period of gusty northwest winds on Friday,
into Friday night. Hence status quo on small craft advisory for
the nearshore waters and gale watch for the north open waters on
Prev discussion... (issued 644 pm cdt Thu apr 25 2019)
update... Showers associated with sharpening mid-level trof
spreading slowly east, should reach the milwaukee area in next 1-3
hours. Showers may slow down and persist a little longer over
eastern areas as low pressure deepens to the southeast of
wisconsin as it moves from southern in into the eastern great
lakes overnight. Never the less, expect showers to end around or
shortly after midnight in eastern areas.
Outflow boundary from earlier convection has slowed its southeast
progression so south to east winds will last a little longer in
the milwaukee to kenosha area.
Aviation(00z tafs)... Showers will spread east across the area
this evening, tapering off from west to east. Showers may slow
down in eastern areas this evening resulting in a period of lower
MVFR ceilings for several hours. Also, a 1-3 hour period of gusty
winds will accompany the showers, with gusts to 25 kts possible.
Clearing skies are expected later tonight into early Friday.

this evening through Friday... Forecast confidence is high...
cold front is pushing through this afternoon. A few isolated
showers and storms have popped up along the front. Upper level
divergence, vorticity, and frontogenesis will push through the
area late this afternoon through the evening bringing the main
rain focus behind the front.
Upper level support will shift east of the area late tonight with
drier air filtering in for Friday. The low level jet will
increase throughout the day Friday and sunny skies will allow us
to mix down northwesterly gusts up to 35 mph.
Friday night through Saturday night... Forecast confidence is
winter strikes back, again!!! A strong low pressure system will|
move to our south Saturday morning into Saturday evening. Newest
models suggest that southern wisconsin will see mostly snow from
this system as 850mb and 925mb temperatures should remain below
freezing throughout most of the CWA during the duration of the
event. Surface temperatures will likely remain in the 30-35 degree
range through the event, which should make for 3-7 inches of
accumulation on grassy surfaces with a few inches of slushy type
snow on roads.
This event will consist of a strong upper level shortwave digging
into the midwest with strong vorticity advection in association
with a bit of a coupled jet situation, which generates strong
omega values. In addition, there is ample moisture throughout the
column with a fairly long period in the dendritic growth zone. The
low and mid levels look very favorable as well with strong waa,
strong frontogenesis and some low level jet influence.
There is still some complications with the time of the day and the
impact this may have on road conditions. However, given the
likelihood for heavier snow bands, rates should overcome the
these concerns for the majority of this event. In addition, given
that this is a tightly wound thermodynamic system slight
variations in the track can greatly impact where the most snow
will fall, thus there is still some uncertainty in snow totals.
Assuming this forecast holds together, we may need to issue a
watch advisory for Saturday afternoon evening over the next 24
Sunday through Thursday... Forecast confidence is medium...
Sunday will be a return to dry weather but cold air behind the
system and fresh snow on the ground have caused us to lower
temperatures despite snow mostly melting Sunday.
Active pattern for next week with fast mid level flow and quite a
bit of uncertainty. Monday will see another system roll through
the region. This is expected to be a warmer system at this time
bringing rain to our CWA though things could change still with
some potential for a cooler trend. Most of the QPF looks to remain
to our south. Guidance after Monday becomes much more uncertain
where potentially more rain arrives for Tuesday into Wednesday
with another system possibly rolling through on Thursday.
expect ceilings to gradually drop as rain
approaches the area. A brief period of MVFR ceilings is expected
with this rainfall. We are watching for a 1 to 3 hour period behind
the front this afternoon for gusts up to 25 knots but confidence
is low. There is also a slight chance for thunder with activity
late this afternoon and evening but confidence was not high enough
to include in tafs.
Conditions will quickly return theVFR as rain ends with clear
skies expected for Friday. Expect gusty northwest winds to build
late Friday morning into the afternoon.
showers and a few rumbles of thunder are expected this
evening associated with a cold front. Gusty northwest winds will
follow behind the front for a brief period before settling back
down overnight. Northwest winds will pick back up in the morning
across the region with gusts up to 25 knots in the nearshore,
which has resulted in a small craft advisory from 9 am to 7 pm
Friday. Winds will weaken overnight Friday. For the open waters
have issued a gale watch for Friday afternoon and evening due to
expected northwest gales in the far northern portion of the lake.
The next concern will be Saturday when a strong low pressure
system pushes through the region likely bring strong winds from
the north on the backside of the system. This will likely bring
gale force gusts to the southern half of the lake Saturday evening
and overnight, thus a gale watch is likely for this period. In
addition, a small craft advisory will also likely be needed for a
period as well.
