946 FXUS63 KDLH 081148 AFDDLH Area Forecast Discussion National Weather Service Duluth MN 548 AM CST Fri Nov 8 2024 .KEY MESSAGES... - Temperatures at or above normal through most of the next week. - Light rain develops later Saturday afternoon into Saturday night with chances lingering in spots into Sunday night. Rainfall amounts will be light. - Another chance for light rain arrives next Tuesday night/Wednesday. && .DISCUSSION... Issued at 304 AM CST Fri Nov 8 2024 High pressure will provide dry conditions to the Northland today into Saturday morning. Highs will be above normal with them peaking in the mid-forties to lower fifties with winds much lighter than Thursday. An upper low that is currently spinning over New Mexico will move into Nebraska by 00Z Sunday, then continue into Iowa/southern Minnesota by 12Z Sunday before pushing east of the region Sunday night. Tonight will be colder under clear skies and light winds. Lows in spots will drop to around 20, mainly in far northeast Minnesota including the Iron Range. Clouds will be on the increase Saturday ahead of the upper low and chances for rain will occur Saturday afternoon over all but far north to northeast areas of the Northland. Chances will only be from 20-40%. As forcing from the upper low increases Saturday night, light rain should become widespread. Light rain chances will diminish Sunday into Sunday night. Total rainfall will be less than a two tenths of an inch with many locales receiving less than a tenth of an inch. There may be some lingering light precipitation Sunday night as colder air filters in as low pressure departs. The light rain may mix with some light snow in far northern Minnesota but accumulation is not expected. A brief period of high pressure will bring dry conditions back into the region on Monday with highs in the forties. Another upper trough and surface low will bring rain chances back into the Northland Tuesday night into Wednesday. There is general agreement among the global models during this period but there are some significant differences in how quickly they move the features through, and the uncertainty bleeds over into the models ensemble members as well. What this means is that a slower solution like the operational ECMWF would lead a bit more rainfall compared to the faster solutions. After the upper trough/surface low finally do depart, a shot of colder air will move in briefly. && .AVIATION /12Z TAFS THROUGH 12Z SATURDAY/... Issued at 548 AM CST Fri Nov 8 2024 VFR conditions are expected through the period with one possible exception. Light winds Friday night and mostly clear skies may allow patchy fog to form but probabilities are too low to include any mention at this time. Winds are expected to be at or lower than 10 knots for most. && .MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/... Issued at 304 AM CST Fri Nov 8 2024 West to southwest winds continued this morning with some gusts to 25 knots continuing along with elevated waves. The wind and waves will decrease this morning with speeds at or lower than 15 knots this afternoon. The wind will become southerly tonight and increase into Saturday to 10 to 20 knots with higher gusts. Conditions will become hazardous for smaller vessels due to the wind and building waves, especially along portions of the North Shore which will see the greatest wave response. Another round of Small Craft Advisories will likely be needed for portions of the nearshore waters. The wind will diminish Saturday night becoming easterly before shifting to west or northwest on Sunday.
