Area Forecast Discussion National Weather Service Duluth MN 1150 AM CST Fri Dec 3 2021

DISCUSSION. (Today through Thursday) Issued at 325 AM CST Fri Dec 3 2021

Summary: A few days of calm before the snow storm this weekend. Colder temperatures next week.

An upper level disturbance parked over region and an associated warm front off to the southwest has brought a few light snow showers to the CWA. The upper level disturbance will shift off to the southeast as the warm front moves northeastward. This will allow for the snow to move north and east out of the CWA by this afternoon. Some locations could see a quarter to a half of an inch. Saturday looks to be rather quiet with temperatures in the mid 20s to low 30s. After that our attention moves to later in the weekend for our first widespread, measurable snow fall for the CWA.

Northwest flow will continue for the Northland as we move into the weekend. Currently a trough over the Gulf of Alaska will move eastward with time, but not before pieces of energy split off and move out ahead of the trough. More specifically, by Saturday night a strong disturbance moves towards the CWA. This will be the initial start of a prolonged period of snow for northeast MN and northwest WI. Models continue in agreement on the start of snow which will be around 00Z Sunday for the southwest part of the CWA. As the trough transitions into its next phase this is where the models differ a bit. The GFS and ECMWF have an upper level low pressure developing by Sunday afternoon, whereas the Canadian and NAM12 still have an open trough. Regardless, the axis of higher snow totals appears to move northeastward towards the Arrowhead. For the same time frame, the associated surface low pressure does vary on location per the aforementioned models, however no matter the solution it is still west of the CWA thereby allowing for onshore flow for the North Shore. This will create a good scenario for lake effect snow to accumulate along the North Shore. Greater than 8 inches is likely for southern Lake and Cook Counties along with blowing and drifting snow as the winds will become gusty Sunday afternoon. Models come back in agreement for Sunday night with a trough over the far northeastern portion of MN to northwest WI. Due to that, a TROWAL and deformation zone will likely not be the leading cause of higher snow totals, but the prolonged period of snowfall will give the northland its first widespread measurable snowfall. Moving into Monday, lake effect snowfall will transition to the South Shore with likely snow totals of at least 8 inches.

After this systems moves out, the region will be in a caa pattern along with fresh snowpack which will lead to a cold start to the work week with high temperatures in the single digits to low 20s from northwest to southeast respectively.

AVIATION. (For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1150 AM CST Fri Dec 3 2021

MVFR cigs are expected over the next few hours with pockets of VFR conditions interspersed throughout the stratus deck. LIFR conditions in HYR are expected to transition to MVFR within the next hour. Expect skies to clear later today with VFR conditions persisting through the remainder of the period. Gusty winds are likely throughout the afternoon and overnight hours as winds become west- northwest.

MARINE. Issued at 325 AM CST Fri Dec 3 2021

Winds will initially be light and variable this morning before they increase this afternoon out of the southwest at 10 to 15 knots with gusts to near 25 knots. Waves will begin to build this afternoon with the highest waves over the South Shore at around 5 to 7 feet. By this evening winds will switch around to the northwest setting up the North Shore with katabatic winds which has lead to a Gale Warning. Otherwise, the remainder of the zones will be in a Small Craft Advisory through Saturday afternoon.
