What forecasters said that day
The local office's own words before this small craft advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Duluth, MN wrote its last area forecast discussion before this small craft advisory went out at Mar 22, 12:35 PM CDT, 2 hours 28 minutes earlier.
Area forecast discussion, Mar 22, 12:35 PM CDT, 2 hours 28 minutes before
Area Forecast Discussion National Weather Service Duluth MN 1235 PM CDT Mon Mar 22 2021 .DISCUSSION...(Today through Sunday) Issued at 452 AM CDT Mon Mar 22 2021 Summary: We have several chances at precipitation through the forecast period. We have an exiting shortwave, and we have some lingering light rain with it across our far east this morning. Then, we have a wet spring system that moves through the area late tonight through Tuesday and Wednesday, which should bring a round of much needed precipitation. The active pattern continues through next weekend with some smaller chances for precipitation through Sunday. Today, the cold front and associated short wave will exit the area to the east. The precipitation has been slow to come to an end, but should be out of the forecast area by mid morning, if not sooner. Some hi-res models are depicting lingering showers over the Arrowhead into late morning and am carrying some slight chance pops, but do not expect much out of these, considering the dry airmass coming into the area from the west behind the cold front. The front is only going to get about half way through the forecast area today before stalling and washing out somewhat, so we will have a large temperature range across the area this afternoon. Highs should get into the upper 50s once again over northwest Wisconsin, but stay mostly in the 40s for northern Minnesota. Attention then turns to the strong upper low that swings out of the 4 corners region this morning and pulls northeast, sliding past eastern Kansas on Tuesday, and through Wisconsin on Wednesday. The broader upper level flow has a broad ridge over the East Coast, and a deep broad trough over the western half of the CONUS, producing the steeply angled trajectory of this system. This system will slowly push the front back north tonight and between the warm air advection and resulting frontogenesis and some weak leading shortwaves, should bring a band of precipitation into the forecast area by morning. Have slowed down the advance of this precipitation, but not by overly much as this system has a good tap of moisture out of the Gulf due to the large amplitude this system has. The warm air advection wing of precipitation will lift slowly north across the area on Tuesday, with the main upper low with the stronger dynamics and isentropic lift spreading into the area for Tuesday afternoon and night before finally pulling off to the east Wednesday afternoon and evening. Precipitation type are a fairly big concern with this system, with long periods of rain, with some rain snow mixture tonight and Tuesday night, and some snow accumulations during the overnight Tuesday night and Wednesday morning before the precip ends. The latest model runs have come in a little warmer, so have reduced the snowfall accumulations somewhat for the deterministic forecast, but uncertainty remains fairly high and I expect further changes with this. There is also some potential for freezing rain in the models, but any instances of it are likely to be bracketed by rain/snow, and impacts should be minor, if anything. A follow-up system should affect areas mostly east of the forecast area in the Thursday night and Friday time frame, but with the uncertainty going on in the nearer terms, confidence is low in this system and have kept pops on the low side. We will also be colder with this system, bringing higher chances for accumulating snow, assuming it does affect the area. More chances for precipitation are lined up for the weekend, but models are in poor agreement out here, and have low confidence at this time in these. Again, we will be cooler than we have been through the weekend, so we have higher chances for accumulating snow with any precipitation chances. && .AVIATION...(For the 18Z TAFS through 18Z Tuesday afternoon) Issued at 1231 PM CDT Mon Mar 22 2021 An area of IFR clouds is quickly lifting and dissipating to MVFR before leaving the area VFR for most of the forecast. A large area of low pressure will arrive Tue/Wed and will cause low cigs and vsbys and probably some gusty winds at KDLH. Precipitation type may also be fluctuating between rain/snow. && .MARINE... Issued at 947 AM CDT Mon Mar 22 2021 Quiet today with southwest winds of 5 to 10 knots. A strong area of low pressure approaches the area on Tuesday which will bring rain and increased winds. Winds are expected to veer to the northeast on Tuesday and strengthen to 15 to 20 knots. Wind gusts on Tuesday may reach up to 30 knots. At this time, gales are possible, but Small Craft Advisories are more likely. Waves may build to 6 to 8 feet on Tuesday, except in Chequamegon Bay where waves will be around 1-3 feet in the ice free areas. The hard part of this forecast is how much of the stronger winds will be able to surface as the lake remains colder than the air mass giving a bit of cushion. && .PRELIMINARY POINT TEMPS/POPS...
