Area Forecast Discussion
National Weather Service Gaylord MI
731 PM EDT Sun Aug 28 2022

.NEAR TERM...(Through Tonight)
Issued at 315 PM EDT Sun Aug 28 2022

...Showers/thunderstorms becoming numerous tonight...

High Impact Weather Potential...a few strong thunderstorms
possible northern lower MI into this evening. Locally heavy rain.

Broad warm/moist advection continues, ahead of a cold front
entering western MN. A band of showers/storms continues well ahead
of the front, with activity extending from central MO to central
upper MI. Sct showers along a warm-advection wing have been
lifting across nw lower MI this afternoon. BL moisture ramps up
behind this band, and a cluster of convection has formed in w
central lower MI, between CAD and GRR. Some of the southern cells
in this cluster are surface-based, with MlCape values nearing
500j/kg. Precip trends area the main concern.

Increased forcing and moisture will amp up precip chances tonight. The
most obvious inbound forcing mechanism is an MCV lifting across
far eastern WI. A severe tstorm watch is in effect ahead of this
wave, over northern IL and southern WI. Other MCVs are possible
tonight. We still have window for respectable surface-based MlCape
values (up to 500j/kg) to push into southern sections thru
sunset. After that, we transition to elevated convection, with
MuCape values in high triple digits. The most widespread precip
will occur then, crossing the area w to e between 10pm and 6am. A
stronger storm or two remain possible this evening, mainly in the
south, where instability is highest. Neither Cape nor shear values
(0-6km bulk shear 30-35kt) quite rise into the realm where severe
storms become a major concern.

Some potential for low-end training convection tonight, with storm
regeneration on the southern flank of existing cells lifting nne-
ward. Average rainfall amounts across northern MI tonight look to
be in the neighborhood of 0.50", but localized 1-2" totals are
likely. This seems unlikely to result in flooding here; a worst-
case scenario that dumps even heavier rain on, say, TVC, is our
most obvious road to hydro concerns tonight.

A balmy night ahead in the warm sector, with min temps mainly mid
to upper 60s. Some fog will develop, especially late overnight
when precip starts to diminish from w to e.

.SHORT TERM...(Monday through Wednesday)
Issued at 315 PM EDT Sun Aug 28 2022

High Impact Weather Potential: Severe storm potential Monday into
Monday evening...

Pattern Synopsis/Forecast:

Broad troughing across the north central CONUS this morning...with a
few main niblets in the flow... Perusal of water vapor imagery
reveals a potent bowling ball of vorticity spinning its way along
the international border in Montana...while ahead of it, elongated
vorticity stretches from the central Plains up into the Upper
Midwest...with another bit of a swirl on the north end of this
across western Ontario. Even a bit of something over Nevada this
morning, too. Shortwave ridging across the Great Lakes, with
moisture/ascent overspreading the upwind side of it across the Upper
MS Valley ahead of aforementioned niblets. Corridor of anomalously
high pwats (at or above 1.5 inches) in this region as well east of a
plume of steep mid-level lapse rates. Strengthening low-mid level
southwesterly flow ahead of the overall troughing as surface high
pressure departs eastward, with the strongest height/pressure
gradients currently to our west across the Upper MS Valley. Nearly N-
S oriented surface boundary extends from TN Valley up through
Minnesota to a surface low in western Manitoba...with surface cold
front stretching back southwestward from that...along plume of
cooler and drier air advecting in on NW flow with that potent
bowling ball to our west. Second surface low and cold front
associated with this as well, across Saskatchewan.

Looking forward...as the bowling ball moves across the Northern
Plains...will look for the troughing to our west to move along ahead
of it. This should shift the focus of the southwesterly flow over
the Great Lakes by Monday morning...with shortwave trough becoming
negatively tilted as additional energy digs into the backside of it
from the northwest. Initial bowling ball should lift northward
Monday into Monday night...and that energy diving into the back of
the trough will aid in driving a cold front through the region at
some point...likely late in the day into the overnight hours. A
little bit of timing differences start to come into play by
Tuesday...as that energy drags the trough axis nearly overhead...and
deepening surface low to our north near Hudson Bay results in
strengthening northwesterly flow and cold advection with time.
Appears that yet another niblet diving south into the back of the
trough at some point Wednesday could drive some additional energy
through the region...though guidance is unclear on how quickly this
happens, how deep the trough will become, and how strong the surface
response will be...which will have ramifications in how cold it will
get for midweek and beyond.

Primary Forecast Concerns:  Severe storm potential Monday into
Monday night...shower/storm potential through the remainder of the
period...

Looks as though there is some potential for activity to linger into
Monday morning...with some continued warm/moist/instability
advection into the region ahead of that potent bowling ball to our
northwest. Exactly how this evolves will have ramifications on the
evolution of later-day development with the cold front, as early day
convective activity/cloud cover could stabilize things to some
degree wherever it occurs. (If it sticks around long enough, it may
not only diminish storm chances, but bust the high temp forecast as
well.) That being said, wherever sunshine does break out, looks as
though surface heating should destabilize the low-levels pretty
quickly, and given the abundance of low-level moisture around, there
is potential to overcome any mid-level capping during the afternoon.
The more moist we end up in the boundary layer, the greater this
instability and cap-busting potential becomes. Additionally, with
some steepening of mid-level lapse rates, am hep to the idea of
greater buoyancy over the area, with probabilistic guidance pointing
toward MLCape in excess of 1000j/kg (some deterministic guidance is
higher). Best shear with this system looks to remain to our west,
for the most part behind the cold front, though there are some
signals of spotty 30+kt deep layer values at times, with the
abundance of the shear likely in the lower levels. So while deep
layer shear values aren't as impressive as we'd typically like to
see them for a severe event...do suspect, with the cold front moving
in, that it will be entirely possible...though perhaps a little more
isolated in nature.

Anticipate wind will be a primary threat with this event, noting
good signals for strong cold pools and increased downburst
potential. Given aforementioned potential for good buoyancy and
steepening lapse rates aloft, will have concerns for hail as well.
Signals for low-level buoyancy and low-LCLs are throwing up some
flags for me...and therefore have some concerns that tornado
potential is not totally zero, particularly noting some guidance
derived soundings showing a little veering in the low-levels in some
areas. Will be something to keep an eye on as we go forward.
Otherwise...with pwats remaining on the anomalous side through the
day (still around or in excess of 1.5 inches)...localized heavy
rainfall totals will remain a threat as well, particularly if any
lingering mesoscale boundaries from early-day convection develop
perpendicular to the flow (increased training potential).

As far as timing goes...as mentioned above, will anticipate some
lingering morning convection, but once that departs, am concerned
things could start to fire right away as skies clear and things heat
up in this environment, as soon as we get enough surface heating to
break the cap. Current deterministic guidance seems to lean toward
the cold front crossing Lake Michigan as early as midday or early
afternoon, which could coincide with aforementioned surface
heating...and forcing associated with the cold front would also aid
in breaking the cap. As usual, best potential attm seems to be
across NE Lower, assuming they are able to clear out between any
morning convection and fropa...but I haven't entirely ruled out some
potential across the rest of northern Lower and perhaps eastern
Upper, either, with signals that things could clear out during the
morning there. (Again...a great portion, if not all of this will be
dependent on whatever happens tonight.) There is some uncertainty in
how quickly the front departs, depending on how quickly the niblet
dives into the back of the trough...which could allow storms to
linger into the evening and perhaps early overnight hours across our
eastern/southeastern zones. All this being said...there are signals
for better forcing/flow to remain to our south amid better
instability...so will have to keep an eye on this, too, to see how
it impacts our convective potential here.

Otherwise...will be brief in covering the remainder of the
period...troughing moving through Tuesday morning should set off
additional showers and potential rumbles of thunder, depending on
how cool we get aloft. Same idea holds for Wednesday with that other
niblet dropping in, with perhaps hints of lake-generated instability
showers if it gets cold enough aloft. Temps will be much cooler
Tuesday and definitely Wednesday as cooler air funnels in; it will
feel a little fall-like out there, particularly as it turns a little
breezier/gustier at times with better flow for a change.

.LONG TERM...(Wednesday night through Sunday)
Issued at 315 PM EDT Sun Aug 28 2022

High Impact Weather Potential: Minimal attm...

Pattern Synopsis/Forecast:

Overall pattern across the CONUS will remain amplified going into
the start of the extended, with that sharp trough shifting eastward
as energy moves both through the ridge and more particularly, over
the top of the ridge in central Canada. With height rises
anticipated into Thursday and Thursday night...surface high pressure
should move into the region, which could lead to continued chilly
overnights if we remain clear. Something to keep an eye on in the
coming days. Appears shortwave across central Canada may keep most
of its impacts north of the border for us...as another bit of energy
digs into the Pac NW late in the period and attempts to trek
eastward through the flow. Though overall, guidance seems to be in
reasonable agreement on the idea...some uncertainty remains in the
forecast for Labor Day weekend. Part of the player in this could be
the signals for tropical activity in the Gulf toward the end of the
period, which are clearer in some guidance than others...so will
have to keep an eye on that in the coming days, to see if that idea
persists or not. Stay tuned.
