Area Forecast Discussion
National Weather Service Milwaukee/Sullivan WI
851 PM CDT FRI MAY 13 2016

.UPDATE...

Area of showers moving along as expected and should clear all of
South Central WI, except the far se corner of Rock Co., by 10 PM
and the far southeast corner of the CWA by 12 midnight.
Interesting wave pattern to the radar returns caused by gravity
waves which also show up in the cloud band stretching from east
central Iowa across southern WI. on the satellite imagery.

Should get some northwest wind gusts to between 20 mph and 25 mph
behind the front.

&&

.AVIATION/06Z TAFS/...

A band of mvfr cigs moving with the increased convergence along
and just ahead of the cold front. The low cigs are not expected to
last more than one hour at any one location as the front moves
across the remainder of southern Wisconsin this evening. Looking
for vfr conditions once the rain showers and pre-frontal band of
mvfr clouds move out of the southeast around 05Z. Expect northwest
wind gusts up to 20 knots behind the front that will continue
overnight into Saturday.

&&

.MARINE...

Gusty northwest winds on track to reach the nearshore waters
around 1 AM so no changes to start time to Small Craft Advisory.

&&

.PREV DISCUSSION... /Issued 305 PM CDT Fri May 13 2016/

TONIGHT - Confidence...Medium

Appch sfc/850 cold front and stg upper jet max will keep area of
rain moving along through srn wi into this evening. Post frontal/caa
regime cloud cover has filled in across the upr midwest. So if
clouds show no signs of a diurnal decrease into the overnight we may
be able to boost temps from going lows.

SATURDAY - Confidence...Medium

Strongly cyclonic flow will be in place with low level thermal
trough well entrenched acrs srn wi. Will leave the sprinkle
potential in place with some shortwave activity within this cyclonic
flow. Synoptic and meso progs are favoring the ern and nern cwa for
best potential of any sprinkles or light showers. So will keep pops
on the quiet side but retain the sprinkles. 925 temps and cloud
cover suggest many areas may struggle to reach 50.

SATURDAY NIGHT THROUGH MONDAY...Forecast Confidence - Medium.

Forecast concerns this period focus on whether conditions support
widespread frost Saturday night into early Sunday. Cold air will
continue to pour into southern Wi tonight and Saturday morning
behind cold front. 925h temps fall to around 0c tonight and
recuperate 1-2 degrees on Sat. Weakening pressure gradient Sat night
will allow winds to decouple, dropping into the 3 to 6 knot range. A
moderate inversion and 925h temps around 1c would result in temps
falling into the upper 20s to lower 30s with clear skies.  However
there remains considerable uncertainty regarding the amount of
clearing expected as both NAM and ECMWF show fairly vigorous mid-
level short wave trof passing across central/srn Wi during the
night.  While low level moisture remains limited, moisture remains
in place between 5k and 10k feet.  With low level thermal trof
remaining close by and axis of upper level jet remaining to the
south of Wi, hesitant at this point to think there will be
widespread and persistent clearing.  Think temps wl still fall into
the mid 30s to result in at least sct to areas of frost at this
point, but too much uncertainty to issue Frost Advisory. Will
continue to mention in Hazardous Weather Outlook product and would
emphasize to the public to hold off on planting any tender
vegetation this weekend.

Uncertain whether how much sunshine will be around on Sunday due to
upstream warm air advection and lingering mid-level clouds and
potential cu development due to lingering low level cold air.  Hence
increased sky cover percentage for Sunday which may be enough to tip
scale to p/s wording.

Leaning more on slower ECMWF, NAM and GEM-NH for slower southward
moving cold front on Monday as GFS remains outlier with faster mid-
level short wave over upper MI at 18Z/Mon.  Pulled low pops across
most of CWA for Mon AM and beefed up Monday MaxT due to drier
westerly flow ahead of front.  Should rise into the mid to upper 60s
most areas, and aftn lake breeze should be held close to lakeshore
due to breezy offshore winds.

EXTENDED PERIOD...

MONDAY NIGHT THROUGH FRIDAY...Forecast Confidence - Medium.

Some moderation in temperature can be expected early next week,
however cloud cover and northeast winds at times will help keep
temperatures in check.  Some discrepancy between GFS and ECMWF on
timing of cold front sliding south across southern WI early in the
period.  Developing low pressure over southern Canada, north of Lake
Superior results in more zonal flow over upper midwest. This upper
low eventually slides southeast across western Great Lakes around
mid-week but GFS more aggressive in showing stronger closed low
aloft.  This solution nudges cold front to the south of WI later
Monday while ECMWF and GEM-NH hold off for another 12-24 hours.

All medium range guidance shows strengthening frontal boundary well
south of WI as low pressure moves eastward along front around mid-
week.  00z GEM-NH had deepening sfc low moving northeast into the
central GTlakes on Wed while GFS and ECMWF flatter and weaker, while
large sfc high pressure builds across upper midwest on Wed.  12z GEM-
NH has now backed on on more amplified solution and has joined
consensus with other medium range guidance.  All guidance now shows
this high pressure area sticking around and influencing our weather
through the end of the week with modifying temps back to seasonal
normals for mid-May, however daily afternoon lake breeze will result
in cooler temps at the shore. The coldest period will be this
weekend.

GFS 5-day 500h standardized anomolies shows 50-100 meter positive
anomoly developing over the GtLakes by the weekend and persisting
into the last full week of May.

AVIATION/00Z TAFS/...Stg jet max rotating se around potent vort
max vcnty nrn Lake Superior. This combined with lower level
frontogenetical forcing will maintain the rain area movg east across
the area tngt. Upstream obs combined with sref cig/vis progs shows
highest confidence in mvfr cigs. Caa sc in the wake of the front
will race in behind the cold front tonight with some diurnal
dissipation plausible. With mid level flow remaining strongly
cyclonic into saturday expect a good deal of mostly vfr cloud cover
with only a isolated sprinkles or a light shra possible.

MARINE...Issued a small craft advisory for later tonight into
saturday due to gusty post-frontal nw wind regime. With airmass
remaining mixy into saturday afternoon will keep the headline going
even though pressure gradient shows some signs of slackening.
