Area Forecast Discussion
National Weather Service Duluth MN
1145 AM CST Sat Nov 20 2021
.DISCUSSION...(Today through Friday)
Issued at 434 AM CST Sat Nov 20 2021
Summary: A clipper system on Sunday is likely to bring light snow
accumulations of 2 inches or less to a large portion of the area.
Lake-effect snow behind this clipper is likely in the Wisconsin snow
belts as well as downwind of Lake of the Woods. The first half of
next week is expected to start off dry with much cooler
temperatures.
A relatively weak shortwave is expected to propagate across the CWA
this morning. A surface cold front, currently located in the far
western CWA, will sweep southeast throughout the morning hours. A
few areas of light returns are being observed on radar this morning.
However, conditions at the surface are expected to remain dry
throughout the frontal passage due to a lack of saturation
throughout the profile. Dry air filtering in behind the cold front
will result in clearing skies this afternoon.
The main focus for the forecast period is a well-forced Alberta
Clipper that will arrive Sunday morning. Global and hi-res models
have this system arriving in the far northwestern CWA around 09z on
Sunday and quickly propagating southeast throughout the morning
hours. The dynamic forcing associated with this system is quite
favorable. A narrow band of low-level FGEN is likely to develop just
ahead of the trough axis. This band of FGEN will coincide with an
area of favorable omega and steep mid-level lapse rates of 7-8
degC/km. Given the strong forcing and expected saturation in the
DGZ, a fairly strong band of snow may develop. The limiting factor
for snow accumulation will be the quick propagation of this system.
Since the band of snow will only remain over a location for a few
hours at most, accumulations are likely to be 2 inches or less for
most locations.
Following the passage of the shortwave Sunday morning, a strong
pressure gradient is likely to develop. This will result in breezy
northwest winds on Sunday afternoon and a decrease in temperatures
as a colder airmass is advected into the area. These cold northwest
winds are likely to develop light lake-effect snow along the snow
belts of Iron and Ashland County on Sunday afternoon and continuing
into Sunday night. Locations near the International Border may also
see lake-effect snow Sunday afternoon and evening as snow develops
in the lee of Lake of the Woods, Rainy Lake, and potentially Red
Lake. Accumulations from lake-effect snow are currently expected to
only be around an additional inch.
Once the lake-effect snow comes to an end on Monday, the first half
of next week will likely be quiet as a ridge develops. Temps on
Monday will remain on the colder side with highs in the low to mid
20s. This will change on Tuesday as southerly winds bring warm air
advection. High temps on Tuesday and Wednesday will range from the
mid 30s to mid 40s. A trough arriving Wednesday may bring precip for
the latter half of the week, but a large degree of uncertainty
exists.

.AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon)
Issued at 1145 AM CST Sat Nov 20 2021
Gusty winds following the passage of a cold front this morning
will persist for the next few hours at most terminals, but a
slackening pressure gradient will allow winds to lighten up later
this afternoon. An area of high pressure will pass through the
region tonight, leading to VFR conditions for the early part of
tonight. A strong upper level trough and surface cold front will
pass through from northwest to southeast early Sunday morning
at INL/HIB/BRD and mid to late morning at DLH/HYR. This will
initially lead to a few hours of LLWS, followed by gusty
northwesterly winds. In addition, MVFR ceilings will be possible
for a few hours along with a quick burst of snowfall, especially
at HIB/INL. The snow may cause MVFR to possibly IFR visibilities
for an hour or two with periods of lighter snow possible later in
the morning.

.MARINE...
Issued at 1008 AM CST Sat Nov 20 2021
Wind gusts from 20 to 30 knots are occurring in the Apostle
Islands according to observations as a cold front passes through.
While the trend will be for winds to decrease this afternoon,
these gusty winds may persist for a few more hours. A Small Craft
Advisory has been issued until 19Z (1 PM) for the Apostle Islands.
The rest of the forecast remains unchanged.
