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 Marquette, MI wrote its last area forecast discussion before this small craft advisory went out at Sep 20, 7:47 PM EDT, 2 hours 15 minutes earlier.
Area forecast discussion, Sep 20, 7:47 PM EDT, 2 hours 15 minutes before
Area Forecast Discussion National Weather Service Marquette MI 747 PM EDT Mon Sep 20 2021 .SHORT TERM...(This evening through Tuesday) Issued at 405 PM EDT MON SEP 20 2021 A strong cold front currently analyzed form northeastern Minnesota to southwestern Iowa per MSAS analysis and surface obs will push eastward across the U.P. tonight in response to a mid-level strong short wave embedded in southwesterly flow out ahead of a long wave trough over the Northern Plains. Before that front gets here, scattered showers are expected over the next few hours over the central and eastern U.P. in response to a subtle mid-level short wave moving northward through the flow atop a moist and marginally unstable PBL. RAP shows a packet of isentropic lift on the 315 K surface (around 600-650 mb) lifting northward across the eastern U.P. over the next couple hours which will likely lead to an increase in shower coverage. Despite visible satellite showing some nucleating occurring, no lightning has been observed yet over our area. However, have maintained a slight chance of thunder for this round of showers through this evening. Tonight, that cold front will plow across the U.P. with a line of heavy showers and likely some thunderstorms, especially west half. NAM shows MLCAPE rising to around 1000 J/kg this evening ahead of the line (the GFS, as usual, shows less). There will be strong shear thanks to a 40-50 kt LLJ overhead, including 0-3 km shear vectors around 30-40 kts, but deep layer shear vectors are oriented mostly along the front. That said, there could be just enough cell growth off the front for isolated bowing segments within a larger broken line of storms tonight, hence the SPC Marginal Risk for severe weather, but with the front moving quickly eastward across the area it will probably be hard to keep any storms discrete. Models show instability waning somewhat overnight, but there should be enough to maintain at least a chance of thunder all the way into tomorrow morning when the front reaches the eastern U.P. This strong LLJ overhead will also lead to yet another night of gusty downslope winds along the Lake Superior shoreline with some 30 mph gusts possible before the front arrives and winds veer around to WNW. Tomorrow, 850 mb temps drop to around 2-3 C behind the front leading to a much cooler day. In fact, the air aloft will be cool enough that there will probably be some lake-effect clouds and rain showers over the west half. The better chance for those showers will be in the morning when there is enough remnant moisture behind the front that upslope ascent will compensate for very marginal lake-based instability. It will be breezy much of the day as well surface pressure rises around 3-5 mb/3 hr behind the front and steepening lapse rates in the CAA regime allowing some 20+ mph gusts to mix down to the surface (30 mph over the Keweenaw and along the Lake Superior shoreline east of Marquette). However, the pressure gradient weakens quickly in the afternoon leading to a decrease in wind gusts, especially after about 18z. The cool air aloft and scattered clouds will keep temps nearly steady in the upper 50s to low 60s, except in the mid 60s far south central. .LONG TERM...(Tuesday night through Monday) Issued at 340 PM EDT MON SEP 20 2021 Long term period continues to present a few opportunities for rain showers, but also a couple of very nice days. Going into the weekend, there's still a good bit of uncertainity in the progression of a system dropping southeast through Ontario and the Great Lakes. Overall high temps through the period appear near to just above normal for a majority of the period, with a few chillier nights early in the period. Starting off on Tuesday night, continued light CAA and midlevel ridging extending across the Plains into the northern Great Lakes should help clear out skies from west to east. This should allow for raditional cooling to let much of the interior west to dip into the mid-upper 30s. Elsewhere lows should buttom out in the 40s given the delay in clearing or the moderating influnces of the lakes. Light winds in the decoupled lower atmosphere could allow for some frost formation, especially if lows exceed expectations. Ridging will continue Wednesday and given 850mb temps progged to be 1-3C, daytime highs should top out near 60 or in the low 60s. Skies are expected to be clear to partly cloudy, with some exceptions being in the downwind of Lake Superior where some light lake effect rain showers will be possible. Elsewhere on Wednesday, the earlier week trough is expected to be blocked by a building ridge off the east coast. Soon after, the trough is expected to intensify as surface cyclogensis occurrs and close off the upper level trough over the Ohio River Valley/central Appalacihans. From there, the low is progged to lift north/northeast. Models have come into fairly good agreement on this evolution, but vary some on timing and placement. Overall, rain showers associated with this system will be possible Thursday into the evening hours, mainly in the east. Upstream another shortwave is expected to dip south and reinforce the broad troughing over eastern Canada. As expected, there's still notable differences among the guidance about whether or not another closed low will develop over the Upper Great Lakes or remain an open wave as it transits eastward. Depending on this evolution, there could be a few opportunities for rain showers this weekend. && .AVIATION...(For the 00Z TAFS through 00Z Tuesday evening) Issued at 747 PM EDT MON SEP 20 2021 Sharp cold front and associated shra/tsra will move across the area tonight. Until fropa, expect LLWS at all terminals as 45-50kt low- level jet translates across Upper MI. With the shra/tsra at IWD/CMX, MVFR conditions will occur, followed by IFR to low MVFR as winds shift to an upslope w to nw direction. At KSAW, abundant low-level moisture and upslope flow will result in IFR cigs until fropa. MVFR cigs will then prevail at all terminals thru at least Tue morning. While IWD/CMX should improve to VFR in the aftn as cloud bases lift, KSAW may remain MVFR thru the day. && .MARINE...(For the 4 PM Lake Superior forecast issuance) Issued at 414 PM EDT MON SEP 20 2021 Tonight, a strong cold front will pass across the lake. Out ahead of the front, southerly winds could reach gale force for a few hours over the north central and eastern lake. Issued a Gale Warning through midnight for the potential for southerly gales, but confidence is not overly high thanks to the stability with warm air over the cool lake surface. The best chance of seeing any gale force gusts will again be at the higher observing platforms. Behind the front, winds will quickly veer from south to NW late tonight. Winds behind the front are expected to be around 20-25 kts west half and 30 kts east half with some more gale force gusts possible. Could have extended the Gale Warning to cover the NW wind portion of the event as well, but decided against it since confidence in seeing gale force winds behind the front is even a bit lower than it is ahead of the front. Winds will subside below 20 kts by Tue afternoon west half, and by late Tuesday night east half, and then remain light through at least Thursday morning. On Thursday, a low is expected to lift northward out of the Ohio Valley and bend back westward towards Lake Huron. Depending on the track and strength of this low, there could end up being some gale force gusts on the far eastern lake Thursday into Thursday evening. However, confidence is still low at this point, so have decided to just mention that here rather than explicitly include it in the forecast. Westerly winds around 20 kts are expected across the lake on Friday followed by lighter winds on Saturday. && .MQT WATCHES/WARNINGS/ADVISORIES... Upper Michigan...
