.DISCUSSION...
Issued at 300 AM CST Fri Jan 10 2025

Light snow showers continue this morning, as weak cold
advection allows for weak low level instability. A secondary
cold front, associated with the upper level trough, is entering
northwest Minnesota this morning and will move through the area
today. Weak forcing and continued cold advection will maintain
steeper low level lapse rates and despite drying aloft, expect
flurries and snow showers to continue through this afternoon.
Best chance of accumulations will be across northwest Wisconsin.

A brief break in snowfall is expected tonight, before the next
system arrives Saturday. A clipper will drop into the northern
Plains and move toward the Midwest, bringing light snow to the
Northland Saturday and Sunday. Guidance continued a slightly
upward trend with snowfall amounts, with 2-3 inches for most of
the area. If low level winds remain out of the east to southeast
at the onset of precipitation, some drier air could erode those
totals. However, if flow becomes more southerly, which is
suggested by some guidance this morning, amounts could trend
upward especially along the North Shore, where lake effect
enhancements could push snow amounts closer to advisory
criteria. South Shore lake effect showers will continue in
Monday.

Colder air arrives early next week as surface high pressure
slides southward through the Plains. This keeps the Northland in
deep layer northerly flow. Highs Monday and Tuesday remain in
the single digits with wind chill values both mornings in the
-15 to -30F range.

.AVIATION /12Z TAFS THROUGH 12Z SATURDAY/...
Issued at 550 AM CST Fri Jan 10 2025

A cold front will move through the area today, with winds
increasing from the northwest at 6-12kts with occasional gusts
of 15-18kts. A stratus deck will likely vary from IFR to VFR
through at least this morning, before cig heights gradually
increase to VFR this afternoon or early evening. Cannot rule out
scattered flurries or light snow showers, accompanied by a
brief reduction in vis. Accumulations are forecast terminals
will be minimal.

.MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/...
Issued at 300 AM CST Fri Jan 10 2025

A secondary cold front will move through the area today, with
light snow showers or flurries continuing over western Lake
Superior. Winds and waves will be quiet Saturday and Saturday
night. Strong northwesterly winds are expected by Sunday
evening as another system moves east of the area. Hazardous
conditions are possible late Sunday through Monday.
