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 Oct 19, 12:37 AM CDT, 4 hours 55 minutes earlier.
Area forecast discussion, Oct 19, 12:37 AM CDT, 4 hours 55 minutes before
Area Forecast Discussion National Weather Service Duluth MN 1237 AM CDT Tue Oct 19 2021 .DISCUSSION...(This evening through Sunday) Issued at 325 PM CDT Mon Oct 18 2021 Summary: dry conditions continue through Tuesday night before increasing chances of showers, and maybe a thunderstorm or two, moves across the southern portions of our forecast area. Temperatures will fall to below-average values for the latter half of the week. Some snow may fall for Friday into Saturday, but no accumulation is expected. High pressure ridging will remain in place across the Northland through much of the day Tuesday, keeping conditions mostly clear and dry. Warmer than normal temperatures will continue Tuesday, with highs in the middle 50s over far north-central Minnesota to the upper 60s across northwest Wisconsin and adjoining areas of Minnesota. A dry cold front will sag southward Tuesday across northeast Minnesota, but the only impact will be increasing cloud cover. The cooler air associated with that front will progress southward across the rest of the region. Attention then turns to Wednesday as a nearly vertically-stacked area of low pressure makes its way towards the Northland. Model guidance is in very good agreement that the track of the surface low will remain just to our south, putting the most favorable area of deformation/frontogenetical forcing along our southern areas. Instability will be very modest along the baroclinic zone of the aforementioned front, generally around a few hundred to 500 J/kg of most-unstable CAPE, so a thunderstorm or two can't be ruled out. Rainfall amounts have increased slightly with this forecast package, with most locations seeing between one-quarter and one-half of an inch in total, with some isolated higher amounts possible. Precipitation should wind down sometime Wednesday night into Thursday. Dry conditions will return for Thursday, and generally continue through the upcoming weekend. We did increase the PoPs for the Friday/Friday night time frame across our northeastern areas due to a longwave upper-level trough setting up across the northern CONUS. Cyclonic flow/cold air advection will develop, which should be able to help squeeze out some precipitation. The GFS sounding shows a saturated layer of air within the dendritic snow growth zone, so it's possible we could see our first snowfall of the season for some areas later this week. However, ground temperatures should be too warm for anything to really accumulate. Much cooler temperatures are expected for Thursday through Saturday, with high temperatures in the lower to middle 40s, and overnight lows in the upper 20s to lower 30s. && .AVIATION...(For the 06Z TAFS through 06Z Tuesday night) Issued at 1237 AM CDT Tue Oct 19 2021 Mostly VFR conditions through the TAF period. A LLJ moving over the region will bring the chance for LLWS to INL, HIB, and DLH early this morning. Light south winds will switch to the northwest throughout the day as a cold front moves across the region from northwest to southeast. Some MVFR and IFR ceilings are possible with this front, but will only affect INL and HIB Tuesday afternoon and evening. Some gusty northwest winds are possible at INL, HIB, and DLH as the front passes through tomorrow afternoon and evening. && .MARINE... Issued at 330 PM CDT Mon Oct 18 2021 Quiet and dry conditions are expected through the daylight hours Tuesday as a ridge of high pressure remains settled across the region. Winds will be east to northeasterly through the evening hours, generally around 5 to 10 knots, turning more southwesterly tonight, remaining around 5 to 10 knots. Hazardous marine conditions are expected to begin Tuesday night, lasting through the day Wednesday as an area of low pressure intensifies and makes its way towards western Lake Superior. Winds will turn more northeasterly and strengthen, resulting in building waves across the South Shore. Winds between 15 to 25 knots, with gusts around 25 to 35 knots, are expected as well. Wave heights of 4 to 8 feet are expected Wednesday along the South Shore. Small Craft Advisories will likely be needed Wednesday due to these higher winds and waves. There is a potential for gale-force winds during the daylight hours Wednesday. && .PRELIMINARY POINT TEMPS/POPS...
