Area Forecast Discussion
National Weather Service Gaylord MI
433 AM EDT Tue Apr 4 2023

.NEAR TERM...(Today through Tonight)
Issued at 427 AM EDT Tue Apr 4 2023

...Significant Ice Accumulations Possible Tonight...

High Impact Weather Potential:

Potential for significant ice accumulations across eastern upper
and far northern lower, as well as marginal severe thunderstorm
and flash flooding threat.

Pattern Synopsis:

Mainly zonal upper-level flow will persist over the Great Lakes
through Tuesday as an impressive trough continues to dig over the
southwest CONUS. This wave will eject over the Great Plains/Midwest
today, providing very strong forcing aloft when combined with a
coupled jet feature to quickly deepen a cyclone that looks to trek
from the Plains towards the upper Midwest tonight. A warm front
extending east from the cyclone center is expected to gradually lift
northward across the southern half of the lower peninsula today,
eventually lifting into the CWA near the end of the period.

Forecast Details:

A complex forecast is in store for northern Michigan today and
tonight as the impressive system discussed above works into the
region. Latest radar imagery and model guidance brings confidence
that the vast majority of ongoing precipitation across mid-Michigan
will remain south of the CWA through the morning hours. Mainly
precip-free weather is anticipated across the area today before
strong mid-level warm advection generates a swath of precip that
should lift into parts of northern lower and eastern upper later
this afternoon.

Current confidence is that this precip will initially fall as mainly
snow into the early evening hours before continued strong WAA builds
the mid-level warm nose above freezing, leading to a transition to
sleet/freezing rain. This is expected to be the most impactful
portion of the forecast period as 0.50-1.0" of precip is expected to
fall as freezing rain -- likely leading to ice accumulations over
0.25" on some surfaces across the eastern upper peninsula. It should
be emphasized that this is a complex forecast scenario as forecast
soundings display an elevated warm nose as warm as 10-13C, which is
very impressive -- to the extent that it casts at least some doubt
as far as what form precip will fall as during certain periods. For
example, what would typically be considered "sleet" soundings with a
deep sub-freezing layer extending to around 850mb or higher with
surface temps well into the 20s may actually fall as heavy freezing
rain given how anomalously warm temperatures aloft will be.
Additionally, ice accumulation may be relatively inefficient with
how heavy precip will be falling -- especially on lined surfaces
like powerlines when compared to flat, elevated surfaces.
Regardless, significant ice accumulations will be possible on
surfaces across portions of the area. This would lead to slick, and
potentially dangerous travel conditions at times Tuesday night into
Wednesday morning.

To further complicate matters, the chance for localized flooding and
a severe thunderstorm or two cannot be ruled out for the same time
period. Instability with steep lapse rates aloft may support
elevated thunderstorms -- even in areas with sleet/freezing rain
falling. Strong shear aloft may help support a marginal hail threat
with any more organized thunderstorm that works into the CWA, but
chances are low at this time. PWATs exceeding 1" with the potential
for training convection over a period of several hours will lead to
the potential for localized flooding, especially with a melting
snowpack.

.SHORT TERM...(Wednesday through Thursday)
Issued at 427 AM EDT Tue Apr 4 2023

High Impact Weather Potential: Severe storm risk of Wednesday has
potential to bring higher end impacts if everything comes together
perfectly.

Pattern Synopsis: Mature cyclone is progged to be over the MSP area
around 12z Wednesday, complete with potent jet streak (150kts+ over
KS/MO/IA) running from TX to Lake Superior. Well developed LLJ will
be advecting warmer air into the region as a sfc warm front surges
northward across northern lower Michigan before largely stalling out
just south of the Straits. Copious moisture in conjunction with an
impressive theta-e surge will keep PWATs well above climo
tendencies, and forcing will remain strong enough for some lingering
convection into the early morning on Wednesday. Eventually, a dry
slot tries to work in and suppresses convective processes across
northern lower as an attendant cold front surges eastward across
Wisconsin. Convective initiation looks to be suppressed into the
afternoon as a warm nose aloft keeps capping on the atmosphere,
while surface warming is maximized through peak afternoon heating.
Eventually, around 18z, the cold front moves onto the Lake Michigan
shoreline, providing ample forcing to generate convection in a
destabilizing airmass, complete with ample shear. The front surges
across northern lower between 18z and 23z, generating a quick-moving
round of convection across Michigan immediately along the sfc cold
front. On the backside of the front, subsidence from colder and
drier air rushing into the region will commence a period of superb
momentum transfer from aloft as 850mb flow around the upper low
remains amplified into much of Thursday. In addition, colder air
aloft and steep lapse rates at the surface may become conducive to
support lake effect instability over Lake Superior where better
synoptic moisture lingers, although diurnal heating and just enough
synoptic moisture may force some low level convection into far
northern lower where the coldest air lingers. Eventually, sfc high
pressure returns overnight Thursday, with momentum transfer tapering
down into Friday.

Primary Forecast Concerns: Severe weather threat from a potential
line of storms Wednesday afternoon in northern lower, followed by a
prolonged period of stronger synoptic winds, possibly coinciding
with snow showers on Thursday which may bring reduced visibility
across the eastern Yoop.

We start Wednesday with a warm front lifting through Michigan, with
some continued showers and thunder looking likely across far
northern lower and into the eastern Yoop to start the day. Guidance
soundings continue to paint a brief window of continued elevated
CAPE. Guidance also suggests a slow crawl above freezing north of
the Bridge, which may leave freezing rain risks lingering into the
morning hours across the eastern Yoop through about 14z. Eventually,
the warm front surges into far northern lower by around 15z, which
should come complete with a surge in warmer air and clearing across
eastern upper and especially northern lower Michigan. This will help
quickly destabilize the atmosphere across northern lower as theta-e
advection continues to draw in higher sfc dewpoints (likely 60F+
south of the front) in conjunction with a warmer layer of air aloft
(850mb temps as high as 15C) that will keep a cap on the atmosphere.
Surface temps will continue to rise, likely peaking in the upper 60s
to lower 70s across much of northern lower, and into the upper 40s
and mid 50s across eastern upper (areas near the water can be
locally colder owing to lake sfc temps hovering around 2-4C, which
will significantly modify the airmass in lakeshore communities and
the eastern Yoop). As of now, the warmest temperatures look to favor
spots south of M-68, which is where the greatest instability (and
therefore the eventual threat for severe weather) would build given
higher sfc temps.

As this instability builds, a cold front will be in the process of
racing eastward across Wisconsin, and looks to approach the Lake
Michigan shore at MBL up to Leelanau County generally around 18z.
This will be the primary forcing feature to contend with for the
afternoon, given the jump start in lift that will likely
materialize. Concerns are mounting over the prefrontal maximizing of
warm air advection as well (which will coincide with peak diurnal
heating), and will be when sfc air temps rise into the convective
temps and thus provide the breaking of the cap right along the
front. This will be of great concern for severe weather potential
owing to most guidance painting a narrow stripe of SBCAPE well over
1,000 J/kg just ahead of the front, which will be more than enough
to support updrafts interacting with anomalously volatile
atmospheric dynamics expected to be in place. Guidance continues to
show very high amounts of shear (0-1km bulk shear 35-50kts, 0-6km
bulk shear 50-70kts... 0-1 SRH is also progged at 250+ and 0-3 SRH
350+). Unfortunately, this suggests that any updrafts that initiate
along the frontal boundary will be able to quickly organize and
become severe, and potentially supercellular if a discrete storm
mode is realized in the hour or two after initiation, which would
insert a tornado threat into the picture given very low LCLs
(progged 500m or less in places) along with a risk for large hail.
In addition, very fast 850mb flow (45-65kts) will support the risk
for damaging winds being transfered to the surface, and very fast
storm motions, which would lead to any given area probably seeing a
quick window (30 minutes or less) of peak threat along the front.
While rainfall may be heavy for a brief time, flooding does not look
to be of great concern. In the event that storms congeal into more
of a linear mode as they cross Michigan, the threat for damaging
winds will become far more widespread, though given the likely QLCS
setup, it is still going to be possible for some tornadic activity
to develop given how volatile the atmosphere is progged to be.

That being said... there are still some considerable uncertainties
that may hinder not only the tornado setup but how widespread this
potential round of severe weather will be. The first and most
pressing will be how efficient moisture transfer will be across the
region. Some CAMs are hinting at prefrontal activity firing across
Ohio and Indiana in the morning hours, which my disrupt the
efficient moisture feedback into the region, and therefore, lowering
instability. In addition, if efficient clearing cannot be realized
Wednesday morning and sfc temps fail to rise to where they are
progged, this will also potentially disrupt convective processes as
well, and potentially lower the severe threat. Regardless, given the
timing of this potential window for severe weather favoring the end
of the school day and after school activities, it is imperative to
keep a very close eye on this situation as it becomes more
apparent... mainly because even if the deeper convection and higher
impact severe weather scenario does not pan out, even a small amount
of instability will be able to squeeze out likely severe gusts given
how strong flow is aloft.

Following the passage of the cold front, continued strong low level
flow will contribute to a period of strong synoptic winds as low
level lapse rates remain steep and support mixing processes
Wednesday night into Thursday. Soundings show continued flow of 40-
50kts at 925mb across the region, and sfc flow of 20-30mph. This
will be of particular concern in the Straits region where land/water
interactions may create a concentrated corridor of strong wind gusts
well in excess of 50mph Wednesday night and into Thursday as the
upper low very slowly moves out of the area. It is for this reason
that flash freeze potential is of low concern given the drier
airmass and lack of higher QPF during the day Wednesday (lows
Wednesday night are expected to fall into the mid-to-upper 20s for
most, 30-35 near Lake Huron and Saginaw Bay). That being said, the
colder air aloft will be able to support some cellular lake effect
over the eastern Yoop and potentially into far northern lower where
the nose of the coldest air will be placed. Delta-Ts will be
marginal across far northern lower (850mb temps -11 to -13 with
water temps around 2C), while slightly more favorable off Lake
Superior (850mb temps -12 to -15C with better synoptic moisture).
Given the strong flow, would not be surprised to see some nastier
snow squalls along the M-28 corridor and north with how windy it
will be. For far northern lower, it looks like that some diurnal
help may be needed, and given how sunny it will be, it wouldn't be
overly surprising given the higher April sun angle. The parent
cyclone eventually lifts into Quebec, with stronger flow aloft
finally breaking down Thursday night as high pressure forces the
system into Atlantic Canada. There may still be breezy conditions
the first half of Friday but as the high pressure center moves
overhead, flow should taper quite considerably, yielding a sunny
day with temps generally topping out in the mid-to-upper 30s north
and low-to-mid 40s south (perhaps pushing 50 closer to Saginaw
Bay).

.LONG TERM...(Thursday night through Monday)
Issued at 427 AM EDT Tue Apr 4 2023

High Impact Weather Potential: Minimal for now.

High pressure moving into New England will bring about a more
settled period of weather for the weekend, with southerly return
flow building into the Great Lakes. The result is a rise in
temperatures to above normal levels, bringing a delightful taste
of spring weather to the region lingering into the beginning of
next week. Highs may need to be adjusted upward given clearer
skies and southerly flow Saturday and Sunday, but for now remain
progged in the 50s Saturday (colder in the eastern Yoop and along
Lake Huron), and highs bloom into the 60s across northern lower
(50s near the lakes and the eastern Yoop). Given any downsloping
and well-mixing tendencies, would expect warmer temps and lower
RHs (so TVC on Saturday from SSE flow and NE lower on Sunday from
SSW flow). Would not be surprised to see someplace that downslopes
make a run at 70 on Sunday if things can mix out perfectly. While
temps may not be at fire weather thresholds, may need to look
into things given decent flow and the potential for lower RHs,
though at this time, these parameters look marginal at best (this
will be subject to change in the coming days). Beyond the
weekend, there are signals that a cold front will return the
chance for rain showers to the region on Monday, with another
calmer period of weather possible on Tuesday as another area of
high pressure returns.

.AVIATION...(For the 06Z TAFS through 06Z Tuesday night)
Issued at 1145 PM EDT Mon Apr 3 2023

A complex area of low pressure developing over the Central Plains
will impact the Western Great Lakes thru the middle of this week.
A stationary front extending from this low center eastward thru
Illinois...Indiana and Ohio will continue to produce a band of
light rain...most of which should remain south of our area over
Central and Southern Lower Michigan overnight into Tuesday. A
strong warm front will lift into the Western Great Lakes late
Tuesday...Tuesday night and Wednesday...resulting in increasing
POPs...warming temps and strengthening winds thru mid week. VFR
conditions overnight will drop to MVFR on Tuesday as increasing
moisture surges northward ahead of this system. Small chances of
precip will begin to enter our area by late Tuesday afternoon...
with widespread precip developing by Tuesday evening across our
entire CWA. Precip type will remain virtually all liquid across
Northern Lower Michigan...with a mix of snow/sleet and freezing
rain expected across Eastern Upper Michigan Tuesday night. Surface
winds will shift to the E/NE at around 10 kts overnight and
gradually strengthen Tuesday into Tuesday night to 15 to 25 kts
with higher gusts expected.
