The local office's own words before the first event, 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 the first event at Apr 23, 7:20 PM EST, 3 hours 40 minutes earlier.
Area Forecast Discussion National Weather Service Marquette MI 820 PM EDT Sat Apr 23 2022 .SHORT TERM...(Through this evening) Issued at 158 PM EDT SAT APR 23 2022 Shift started with lingering convection making its way out the door into Canadian waters and plenty of low level moisture across Upper Michigan. This moisture and upslope flow resulted in patchy fog across parts of Marquette County and the Keweenaw Peninsula. SPSs were issued for both, and a second SPS has been issued for the Keweenaw Peninsula through early this evening. Motorists are reminded to take their time, drive with their headlights on, and leave extra space between themselves and other vehicles. Moisture has resulted in mostly cloudy skies save for downslope areas in the western UP and across the south. Daytime temps so far have largely topped out in the mid-40s across the central, high 30s in the Keweenaw, and 50s and low 60s in the west. Upstream, RAP analysis depicts surface warm front moving into central Wisconsin and curving northwest toward northwestern Wisconsin. Along this boundary, some light precip has been observed on radar. There also appears to be diurnally driven shower activity, perhaps aided by this morning's exiting convection/frictional convergence in the eastern UP and along the Garden and parts of Luce. Radar signatures suggest only drizzle or light rain in this patch. As we progress through the remainder of the afternoon and early evening, surface boundary is expected to lift into the UP with some isolated/scattered shower activity mainly limited to the central. Upstream, convection out ahead of a cold front is expected to increase in coverage and move in after this period. .LONG TERM...(Tonight through Saturday) Issued at 436 PM EDT SAT APR 23 2022 Warm, moist surface frontal boundary will have crossed over the MI border by the start of this forecast period, allowing for another round of shower and thunderstorm activity. The focus for the activity will be courtesy of a meridionally-aligned upper jet axis approaching and traversing Upper Michigan tonight from the west, ahead of the low pressure system responsible for the weather as of late. Embedded vort maxes will assist with lift; ample PWATs of at least 1", potentially as high as 1.5", will assist with moderate to locally brief heavy rainfall chances; and sufficient available instability will provide the opportunity for lightning to occur. Precip chances then look to wane again during the day tomorrow as dry slotting moves in, then the low turns northeastward, marching toward James Bay by Monday. What to watch for tonight: not an exact repeat of last night, but thunderstorms with embedded moderate to locally brief heavy rainfall could cause water to pond in susceptible areas, coupled with the continued melting of the snowpack where it exists. Lows will run rather high for this time of year, ranging in the 40s and 50s. Once the aforementioned low pulls out of the region on Monday, the next precip chances could occur Monday night into Tuesday as an upper trough axis swings across the Upper Great Lakes region. Much colder air will have returned by then, reintroducing the potential for said precip to fall as snow or a RASN mix. Brief ridging allows for dry conditions mid-week, with the next precip chances arriving late in the week courtesy of weak, passing disturbances. Before the alluded to colder air moves back in early next week, temps look to rise well into the 50s and 60s tomorrow given the surge of WAA. Monday through Thursday is anticipated to run below normal for late April, with the coldest day occurring on Tuesday. Lows will respond accordingly, with teens reappearing Tuesday night. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 818 PM EDT SAT APR 23 2022 Poor flying conditions to persist through the TAF period with low visibilities and cigs. Generally, expect IFR/LIFR at KCMX, MVFR/IFR at KSAW, and MVFR/VFR at KIWD. A prolonged LLWS threat will also prevail at all TAF sites through tomorrow morning due to a strong low level jet. Isolated showers will be possible through tomorrow with isolated embedded thunderstorms tonight. Winds at the surface will generally be southeasterly, veering to the southwest tomorrow morning. Sustained wind speeds will be in the 12 to 20 kt range with gusts up to 32 kts. && .MARINE...(For the 4 PM Lake Superior forecast issuance) Issued at 436 PM EDT SAT APR 23 2022 SE gales to 40 knots this afternoon into this evening will taper down to around 30 knot gusts or less overnight into early Sunday. Although a few gale-force gusts can't be ruled out for the latter half of this weekend into early next week, winds will generally top out to 30 knots or less during this period. By Tuesday through the remainder of the week, wind gusts of 25 knots or less are anticipated. Fog will envelope much of the lake tonight as very warm air temperatures glide across the very chilly Lake Superior waters. Tonight's fog looks to struggle to stick around beyond around midday Sunday as cooler air aloft starts moving back into the region. && .MQT WATCHES/WARNINGS/ADVISORIES... Upper Michigan... None.
