NWS Marquette, MI wrote its last area forecast discussion before the first event at Apr 23, 12:29 PM EST, 16 minutes earlier.
Area Forecast Discussion National Weather Service Marquette MI 129 PM EDT Sat Apr 23 2022 .SHORT TERM...(Today) Issued at 554 AM EDT SAT APR 23 2022 850mb warm front is currently advancing ne across Upper MI. Strong isentropic ascent and strong 850mb theta-e advection owing to 40- 50kt winds have resulted in shra/tsra spreading ne across the area during the night. With CAPE upwards of 1000j/kg for parcels lifted from near top of the inversion and sufficient effective shear, a number of storms earlier in the night were producing small hail. A couple likely produced hail around 1 inch. Torrential rainfall has also been occurring with stronger storms. KMQT radar indicated rainfall rates as high as 5-7in/hr with some storms. Fortunately, storm movement was quick to avoid excessive rainfall. Nonetheless, some locations were impacted by several cells, particularly from eastern Ontonagon County to Keweenaw Bay, btwn L'anse and the Lower Entrance of Portage Canal. Rainfall estimates for the night are into the 1 to locally near 2 inch range in that corridor now. Fog is developing now that shra are beginning to diminish in coverage. With passage of 850mb warm front, expect lingering shra/tsra to end from sw to ne over the next several hrs. Sfc warm front will still be approaching. Any pcpn that does occur after the early morning convection ends should be just patchy -dz with low stratus deck lingering ahead of sfc warm front. Best chc of any -dz, and also locally dense fog as well, would be where se winds upslope. Despite approaching sfc warm front, it will be difficult to get convection going today with fcst soundings generally showing plenty of cinh for parcels lifted from top of inversion. Only exception could be late in the day, more likely this evening, over the far w as low-level jet axis translates across nw WI toward western Upper MI. Also, there may yet be additional development thru late morning, maybe early aftn, over the e before significant drying occurs above inversion. Not sure how far n sfc warm front will progress today. SE flow off Lake MI will certainly impede front, so only far western Upper MI may see warm front slip n of the MI/WI stateline. Low stratus should probably hold on thru the day for many areas, but where stratus breaks (best chc in areas where se winds downslope over the w), temps will push above 60F. Otherwise, expect 50s, trending down thru the 40s F along the Lakes where wind component is off Lake MI or Superior. .LONG TERM...(Tonight through Friday) Issued at 432 AM EDT SAT APR 23 2022 Strong low pressure, deepening over the Dakotas through tonight, will influence the weather over the U.P for the next several days as it slowly lifts northeastward, though northern Minnesota on Sunday and into Ontario Monday. Warm weather this weekend gives way to much cooler weather for early and mid week followed by a slow warming trend. There will also be periods of precipitation Saturday night and Sunday (in the form of rain) followed by snow showers on Tuesday over the northern part of the U.P. There is little agreement with features in the models beyond Wednesday but the overall ensemble mean 500mb heights show shortwave ridging late in the week followed by another trough next weekend. For tonight another round of showers and thunderstorms is expected over the western U.P. as the storm system moves closer and large scale ascent increases. Showers and thunderstorms should weaken/diminish as they move east into the Central U.P, further away from the forcing. Much of the U.P. will start out with temperatures in the 50s Sunday morning (along with dewpoints in the 50s) making it feel a bit humid. Temperatures warm into the 60s Sunday afternoon with additional showers and possibly a thunderstorm or two as a cold front moves from west to east late in the afternoon and evening. This front will signal and end to the brief warm spring weather with temperatures falling below seasonal averages Monday and Tuesday followed by a slow recovery through the end of the week back to near or slightly below seasonal averages. A shortwave passes over the area on Tuesday on the back side of the departing trough. There could be enough forcing/instability for at least a few snow showers over all of the U.P. Additionally, sfc to 850mb deltaTs will be sufficient for lake effect snow showers in the north wind belts, continued with the more widespread PoPs in those areas over the blended guidance. There is a decent amount of dry air working into the area and fairly low inversion heights so thinking any accumulation should be around an inch or so at best. We could be looking at record cold highs on Tuesday (which are mainly in the lower 30s) for locations in the north half of the U.P. High temperatures from the blended guidance in the north are around 30 to 32 while raw guidance is only in the mid to upper 20s. Lows Tuesday night drop into the upper teens over the interior west. While temperatures warm back into the 40s and low 50s for the end of the week they will still be a few degrees below average for this time of year. && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 128 PM EDT SAT APR 23 2022 Abundant low level moisture will keep LIFR/IFR ceilings in this TAF issuance at all sites save for KIWD. There, southeasterly downslope winds has lead to increasing subsidence, which has resulted in VFR ceilings. This moisture, coupled with easterly upslope flow into the Keweenaw Peninsula will keep KCMX at or near airport minimums, with slight improvement being possible this afternoon. Gusty winds of 20 to 30 knots will be possible today and tonight at all sites, and LLWS should also be expected. Upstream convection moves into the region this evening. Shower activity is expected to begin as early as mid/layer afternoon at KSAW and soon after at KCMX/KIWD. Thunderstorms appear more favorable at KIWD and once developed, amendments may be needed to account for activity near KCMX/KSAW terminals. Shower activity is expected to persist across the region through at least Sunday morning. && .MARINE...(For the 4 AM Lake Superior forecast issuance) Issued at 432 AM EDT SAT APR 23 2022 A sfc low pressure system deepening over the plains will keep 20-25 kt easterly winds over the west and 25-35kt east-southeast winds over the central and east this morning. Gale gusts of 35-40kt over the central and east will shift north and be confined close to the international border for this afternoon and evening. Winds will diminish to under 20kt over western Lake Superior tonight and to 20- 30kt across the east as the pressure gradient slackens. A cold front will the move across Lake Superior on Sunday. Winds ahead of it may continue to gust to 20-30kt across eastern Lake Superior. Behind the front, winds will shift west, then northwest. As increasingly colder air arrives, expect west to northwest winds Sunday night thru Tuesday gusting frequently to 20-25kt, strongest over the east half of the lake. Winds will fall to around 20 knots or less across the lake by Tuesday evening through the rest of the week. With shra/tsra moving across the lake tonight, the pcpn falling into the cold marine layer will probably lead to some fog development late tonight/Saturday. This fog will then stick around until cold front passes on Sunday. && .MQT WATCHES/WARNINGS/ADVISORIES... Upper Michigan... None. Lake Superior...

Waves up to 10 feet are expected through the morning along east facing shorelines of Lake Superior. The high waves may cause minor beach erosion and/or minor lakeshore flooding. The rainfall early today combined with warmer conditions, resulting in increased snowmelt, will cause rivers, creeks, and streams to rise today and tonight. Fog could become locally dense this morning. .DAYS TWO THROUGH SEVEN...Sunday through Friday There is a slight chance of thunderstorms on Sunday. Warmer conditions through Sunday, resulting in increased snowmelt, will cause rivers, creeks, and streams to rise into Monday. .SPOTTER INFORMATION STATEMENT...
