Area Forecast Discussion
National Weather Service Gaylord MI
330 AM EDT Mon Apr 20 2020

.NEAR TERM...(Today through Tonight)
Issued at 327 AM EDT Mon Apr 20 2020

Impactful weather: Minimal. Gusty with a small thunder threat south.

Pattern synopsis and forecast:

Large scale upper troughing was in place across eastern North
America early this morning. A shortwave trough was seen driving down
the backside of this larger scale troughing, through nrn Manitoba,
with strong DPVA and WAA in steep 6.5-7.5c/km 850-500mb lapse rates
resulting in strong low pressure in western Ontario. A cold front
curved down through nrn MN and back through ND, while a warm front
was seen lifting into the Arrowhead of MN and through WI. The
atmosphere was relatively dry around these frontal boundaries, with
only some weak higher level reflectivities seen on regional radars.
The deep moisture was in Ontario, associated with the low pressure.
In nrn MI attm, we still have weak high pressure draped across us
and mostly clear skies.

The high pressure will depart east this morning, while the deep low
pressure drifts across Ontario today, and into Quebec tonight. A
cold front will work it's way into the nrn and western Great Lakes
by late this afternoon, and then through nrn MI and the eastern
Great Lakes tonight. Skies will increase in cloudiness through the
day as the pressure gradient tightens, and winds become gusty out of
the SW. While the strongest forcing will remain with the sfc low to
our north, we do get into some WAA by this afternoon, as well as
strengthening DPVA and those steep lapse rates with the arrival of
the aforementioned nrn Manitoba shortwave. While there could be a
few rain/snow showers impacting eastern upper this morning
(associated with another shortwave in western Ontario), the best
precipitation chances will be this afternoon through this evening as
the shortwave and cold front drive through our neck of the woods.
Rain showers are expected to break out across most of nrn Michigan
this afternoon, with cold advection setting in from north to south
through tonight, allowing the rain to mix with and/or changeover to
snow. By very late tonight, low level temperatures get cold enough
for possible weak lake effect snow bands to develop. Also, the
pressure gradient tightens even more so, and gusty NW winds will
likely develop. Finally, there is also a slight chance for thunder
from mainly Grand Traverse Bay to Saginaw Bay, and areas south of
that line. No severe storms are expected. Total snowfall will be
minor, not eclipsing an inch for most all areas of nrn Michigan.

High temperatures will generally be in the middle 40s in eastern
upper to the upper 40s to lower half of the 50s in nrn lower. Lows
tonight will largely be in the middle and upper 20s, with lower 30s
near Saginaw Bay.

&&

.SHORT TERM...(Tuesday through Wednesday)
Issued at 327 AM EDT Mon Apr 20 2020

...Unseasonably Cold with Snow Showers Likely Tuesday...

High Impact Weather Potential...Slippery roadways?

Forecast Concerns...Max wind speeds/gusts, pops and snow
accumulations Tuesday.

Tuesday...Here we go again with another shot of arctic air Tuesday.
It should be plenty cold enough to turn on the lake effect snow
machine yet again (Lake-850 mb delta Ts in the mid teens). The flow
is northwest and there is a decent wrap around moisture (850-700 mb
mean relative humidity a robust 70 percent or so) behind the
departing area of low pressure. Model soundings look good with
inversion heights between 5,000 and 6,000 feet. Oh and there is
sharp cyclonic curvature aloft. If this setup was during the winter
I would be confident there would be discrete/intense banding but as
you know it's not winter so widespread diurnal disruption should be
at work. What I think we'll see is more of a cellular type activity
possibly containing short lived heavy bursts of snow. Overall snow
accumulations should remain low on the order of an inch or less. On
top of all this, northwest winds are expected to be very gusty
(upwards of 40 mph) which could lead to some blowing snow issues
among other possible issues. Temperatures should pretty much flat
line in the upper 20s to mid 30s.

Tuesday night...Still cold enough for lake effect into the evening
hours but moisture quickly drops off as weak surface ridging builds
in. Plus milder air decreases over lake instability so little to no
snow shower activity is expected except perhaps to start the period.
Light winds and clearing skies should allow for decent radiational
cooling conditions after that so went with forecast lows close to
the colder mav guidance in the mid teens to the mid 20s.

Wednesday...An Alberta Clipper dives southeast toward the region.
There is model inconsistency as to how far north precipitation will
get with this system with a slim majority covering the southern half
of the forecast area. Slow warm air advection is shown through the
day but it looks cold enough for precipitation chances to start off
as light snow in the morning with a mix with and change over to rain
in the afternoon (perhaps remaining mostly snow across the far north
but that assumes that precipitation is able to even reach up there).
Highs struggle into the mid 30s to the low 40s.

&&

.LONG TERM...(Wednesday night through Sunday)
Issued at 327 AM EDT Mon Apr 20 2020

...Continued Below Normal Temperatures...

High Impact Weather Potential...Low.

Extended models are in agreement that the upper level pattern
remains troughy across the region which in short means it more than
likely will remain cool over the next several days. Temperatures in
the 5 to 10 degrees below late April averages seems like a
reasonable range. Disturbances moving through the flow will bring
periodic chances for mainly rain showers (but a little snow can not
be ruled out). The blend has lots of slight chance pops which may or
may not be able to be removed by subsequent shifts as the models
hopefully resolve the small differences (for instance like next
weekend which could end up being precipitation free). Unfortunately
for anyone looking forward to warmer temperatures, there aren't any
strong signals that we will see a big break in this pattern through
early May (:<).

&&

.AVIATION...(For the 06Z TAFS through 06Z Monday night)
Issued at 1143 PM EDT Sun Apr 19 2020

VFR conditions with remainder of tonight with just some increasing
high clouds. Next cold front drops south out of Canada today,
reaching central upper Michigan by later this afternoon, dropping
across our area this evening. This front will bring a slowly lowering
cloud deck south across the taf locations. Still expecting VFR
conditions much of today, with lower cloud bases...producing MVFR
cigs and some showers...holding off until this evening. Winds
become southwest and once again become gusty later this morning.

&&

.MARINE...
Issued at 327 AM EDT Mon Apr 20 2020

High pressure departs today, making way for low pressure and a cold
front tonight. The pressure gradient tightens up today, with gusty
SW advisory level winds developing most all areas. After a period of
rain, which will mix with snow into tonight, the gradient tightens
up even more late tonight through Tuesday. This will result in gales
over many nearshore waters. Higher pressure and lighter winds move
in Tuesday night.
