Area Forecast Discussion National Weather Service Duluth MN 356 AM CDT Sat Oct 16 2021

DISCUSSION. (Today through Friday) Issued at 356 AM CDT Sat Oct 16 2021

Summary: Cloud cover will decrease today as a ridge builds over the central CONUS. Expect clear skies through the weekend and into early next week with above-normal temps. The next chance for rain arrives on Wednesday as low pressure moves through the area. Temps following Wednesday's system are likely to be cooler and much more fall-like.

Current analysis shows that the trough that propagated across the CWA yesterday is now centered over northeast WI and the central Upper Peninsula of MI. Drizzle in the wake of this trough has been observed this morning across the Arrowhead and portions of northwest WI. This drizzle is expected to come to an end later this morning as the trough continues to move downstream. Skies will clear today from west to east as a longwave ridge begins to build over the central CONUS. Highs today will be warmer with temps ranging from the low 50s to around 60. Low temps tonight were forecasted on the lower end of guidance due to the likelihood of strong diurnal cooling occurring under clear skies. In addition, the warm air advection associated with the ridge isn't likely to arrive until Sunday morning.

The remainder of the weekend and early next week will see abundant sunshine and well above-normal temps. Temps are likely to peak on Monday with high temps ranging from the mid 60s to around 70. A change in pattern is expected to occur on Wednesday as a low pressure system develops over the Rockies and propagates eastward into the CWA. Global guidance is converging on a time of arrival of Wednesday afternoon. The center of the low is likely to pass through southern MN and WI, which would leave the CWA in the cold sector and near the deformation zone. This will result in a chance for widespread precip throughout Wednesday and into early Thursday morning.

As this low moves into Michigan, cold air advection is likely to occur due to winds both aloft and at the surface turning northerly. A second low over Hudson Bay will enhance the amount of CAA on Thursday. High temps are forecast to return to the 40s and low 50s with overnight low temps dropping into the upper 20s to low 30s. Compared to climatology, these temps will be near normal for this time of year.

AVIATION. (For the 06Z TAFS through 06Z Saturday night) Issued at 1240 AM CDT Sat Oct 16 2021

MVFR cigs in HYR will improve to VFR within the next couple hours as higher cigs advect eastward. VFR conditions are expected throughout the period as a ridge begins to build. There is a small potential for some afternoon VFR cumulus in INL due to northwest flow and cold air advection aloft. However, a lack of moisture in model soundings increased confidence to keep skies clear.

MARINE. Issued at 356 AM CDT Sat Oct 16 2021

Breezy west winds are expected today with sunny skies following the passage of an upper-level trough. Winds today will be around 10 to 15 knots with gusts up to 20 knots for most nearshore zones. There is the potential for a few wind gusts along the North Shore to briefly approach 25 knots for a few hours late this morning as stronger winds develop in the higher elevations of the Sawtooth Mountains and the Misquah Hills. A Small Craft Advisory has been issued for waters from Two Harbors to Grand Marais due to the potential for these gusty winds.

The South Shore from Port Wing to Saxon Harbor, excluding Chequamegon Bay, will see the strongest winds with gusts up to 25 knots. In addition, the Apostle Islands are likely to see higher waves of 2 to 4 feet today and tonight. Small Craft Advisories remain in effect. Sunny skies are expected to continue into Sunday with winds remaining westerly. Wind speeds are expected to slowly ease throughout the day on Sunday. Waves will also subside to 1 foot or less by Sunday night.
