SHORT TERM. (This evening through Sunday) Issued at 337 PM EDT SAT OCT 31 2020

Satellite imagery showing stratocumulus rolling off the waters of northern Lake Michigan onto the eastern half of the Upper Peninsula due to the strong southerly winds present today. Further to the west and northwest, a broad swath of clouds are present due to the extratropical cyclone that is currently intensifying. Several observations of 40-60mph wind gusts have been observed over the Lake Superior waters and shoreline region of the CWA the last few hours as the approaching cold front continues to propagate toward this area. Pressure falls associated with the strong surface low of 992mb will continue to bottom out until reaching somewhere in the 988mb to 990mb threshold over the Canadian Provinces through the remainder of tonight into early Sunday morning. This will create very gusty southerly winds over the waters and inland ahead of the passing cold front before transition to a west to west northwest wind direction. Short term model guidance is showing the cold front likely passing through the region between 3Z-6Z timeframe. Temperatures will be above freezing for the initial onset of precipitation leading to light rain showers at first across the CWA. Profile soundings show a quick transition to sub freezing temperatures at the surface and aloft spreading from west to east once the cold front propagates further to the east. This will lead to a short window of rain/snow mix before turning to all snow. Concerns for light freezing drizzle are minimal at this point of inspection. The northwest snow belts will see an increase in activity once the wind shifts behind the cold front to a northwesterly component allowing lake effect snow to ensue. Snow showers will lead to a general amount of 1-3 inches of snowfall accumulation near the lake shorelines of Lake Superior, with inland areas and the higher terrain seeing localized higher accumulations where persistent snow bands develop. Strong winds will continue on Sunday behind the cold front as the pressure gradient between the approaching dome of high pressure and the departing surface low to the northeast. Wind gusts for the inland areas of the CWA between 35-45mph are likely at the peak time of the event on Sunday. Snow showers will quickly end by mid to late Sunday afternoon from west to east with gradual dissipation of wind gusts near 0Z Monday.

LONG TERM. (Sunday night through Saturday) Issued at 342 PM EDT SAT OCT 31 2020

The strong shortwave that is bringing all the wind and snow across Upper Michigan today will be moving out of the area Sunday night into early Monday morning. Lake-effect snow showers will be concentrated over the east, primarily Alger and Luce Counties but will be tapering off by midnight Monday morning at the latest. Beyond that, a weak shortwave will come close to Upper Michigan Monday which at this moment, looks to remain dry. If anything were to develop, it would be over the far east towards Sault Sainte Marie. Then ridging will take control for most of next week with little chances of precipitation and mild temperatures.

With the Monday shortwave, BUKFIT soundings show it could be a breezy day with a little bit of mixing up to about 2-3 kft above the sfc. GFS is the more aggressive model with this as the NAM does not go that aggressive. With the sfc being dry, think any precip that does fall will evaporate before reaching the ground. Will probably keep wind speeds around 10-15 mph with gusts up to 20 mph. Higher gusts over the Keweenaw Peninsula is a good possibility. Then ridging will take firm control across the Upper Great Lakes region with 500mb heights rising Tuesday through the rest of the week as milder Pacific air moves over Upper Michigan.

Temperature wise, Monday will probably be the coolest day in the extended with that shortwave passing nearby and expecting highs mainly in the 40s. Tuesday will mark the start of several days that will be at or above 50. Wednesday still looks to be the warmest day in the extended with mid to upper 50s in most spots and a few spots reaching the 60 degree mark as well. Overall, it will be a relatively mild and quiet week.

AVIATION. (For the 00Z TAFS through 00Z Sunday evening) Issued at 737 PM EDT SAT OCT 31 2020

Very windy through most of the forecast with decreasing visibilities and ceilings as a potent fall storm system moves through the region. Winds have relaxed at KIWD this evening, but will become gusty from the NW after Midnight as a cold front punches through. KCMX and KSAW to see a similar pattern with a brief decrease in winds then NW winds picking up again as the pressure gradient tightens up and cold air advection kicks in. Wind gusts 35 to 45 knots are likely after 06Z tonight. CAA brings with it lake effect snow showers, as well as reduced ceilings. Expect lower end MVFR ceilings at all three sites at times, in addition to IFR visibilities during the morning thanks to the snow showers and blowing snow. As the storm system pulls away, a gradual relaxing of the gradient will allow winds to drop off a little late in the forecast, while drier air begins to move in and ceilings improve to VFR conditions late.

MARINE. (For the 4 PM Lake Superior forecast issuance) Issued at 337 PM EDT SAT OCT 31 2020

South winds will continue to reach storm force to 50 knots over much of the east half of the lake through late this afternoon as a low- level jet max moves across the area ahead of the powerful cold frontal system approaching from the Plains. As winds shift westerly behind the initial cold front this evening, expect another round of 35 to 40 knots gales across the lake. With the passage of the secondary and stronger cold front late tonight into Sunday, winds will shift sharply to the north-northwest with high-end gales to 45 knots expected over the western third of the lake and then storm force winds to 50 knots over central and eastern Lake Superior. Winds will diminish below gales over the west half late Sun afternoon and by early Sun evening over the east half as the strong low pressure and frontal system lift quickly east. Another low pressure trough moving across northern Manitoba and northern Ontario will increase westerly winds to 30 knots late Sun night and Monday with a few gale force gusts possible across the tip of the Keweenaw and east half of the lake.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
