NWS Marquette, MI wrote its last area forecast discussion before the first event at Apr 25, 6:24 AM EST, 6 minutes earlier.
Area Forecast Discussion National Weather Service Marquette MI 724 AM EDT Mon Apr 25 2022 .SHORT TERM...(Today) Issued at 431 AM EDT MON APR 25 2022 Scattered rain showers are drifting through the Upper Peninsula this morning as a surface low continues its track farther into northeast Ontario with the trailing upper low/cold air not far behind. Forecast soundings show temperatures decreasing at the surface after daybreak this morning with a warm nose in the mid levels hanging on slightly longer over central and eastern portions of the forecast area. This trend has already commenced though over the western third of the forecast area. So, expect some snow to start mixing in with the rain by daybreak over the western counties with a gradual transition from west to east through the morning and afternoon over the central third of the UP. Across the eastern third, rain showers could hang on until this evening before making the transition. However, with only limited wraparound moisture to work with, any snow amounts will be minimal. .LONG TERM...(Tonight through Sunday) Issued at 447 AM EDT MON APR 25 2022 In the big picture, GFS ensembles still show a -AO/-NAO to prevail into early May along with a +PNA. However, there has been a recent trend in fcst guidance toward quicker weakening of these anomalies next week. Nonetheless, these anomalies in the circulation pattern will influence the weather across Upper MI this week and probably thru next week, particularly with regard to temps. Over the next couple of days, Upper MI will be under mid-level troffing with the core of an unseasonably cold air mass arriving Tue into Tue evening (850mb temps bottom out at around -15C). Record low max temps will likely be set at some locations across Upper MI on Tue, and not out of the question that a location or two could have the lowest max temp for so late in the season. Moderation will then occur for the remainder of the week, but temps will remain blo the late Apr normals. With a persistent though weakening -AO/-NAO and +PNA, temps are likely to remain blo normal on the majority of days heading thru the first week of May. Keep in mind at this time of year normal high temps increase by 1F degree about every 2 days. At the end of next, normal high temps generally range from mid 50s north to lower 60s F s central. As for pcpn, no significant pcpn is expected this week. With a mid-level low and core of cold air arriving Tue, expect sct to nmrs -shsn to develop tonight, continuing thru Tue, then diminishing/ending Tue night with departure of the mid-level low/core of coldest air. There will be snow accumulations, at least across the w and n. Dry weather follows on Wed, then a shortwave moving onshore over the Pacific NW on Wed will streak e toward the Upper Lakes, but since it will be cutting thru ridging, it will weaken. Might be some -ra/-sn in the Thu/early Fri time frame. A more significant shortwave moving onshore over the Pacific NW on Thu will probably close off a mid-level low as it crosses the Plains to the Great Lakes region Sat thru Mon. With positive height anomalies expanding across Canada into the N Atlantic, this wave should take a southward suppressed track as it progresses downstream across the CONUS. So, Upper MI may end up on the northern portion of the pcpn associated with the wave, which means a colder -ra scenario, including potentially a mix of -ra/-sn for part of the time. Beginning tonight/Tue, shortwave dropping se across northern MN will close off a mid-level low that will track across Upper MI/far northern WI on Tue. 850mb temps will continue to fall tonight/Tue with the core of an unseasonably cold air mass arriving Tue aftn/evening. 850mb temps are fcst to bottom out at around -15C. The wave and cold air mass will generate late season lake enhanced snow, particularly late tonight thru Tue, under developing deep cyclonic flow. Moisture depth will be deep, to 12kft or more, and there will also be a deep DGZ layer from around 3kft to around 11kft. Fcst soundings still don't show much upward motion thru this deep DGZ, but it will still lead to higher SLRs to fluff up snow accumulations. With low-level wind fields showing sharper troffing into western Upper MI for a time, heavier -shsn should occur in that area, but all of western and northern Upper MI will get accumulating snowfall, generally 1-3 inches tonight thru Tue evening. However, expect locally several inches of snow accumulation in areas where nw to n wind upsloping is maximized. Even away from the w and n, the deep moisture should allow for fairly widespread coverage of -shsn late tonight/Tue. With expectation of considerable cloud cover/lack of sun due to the deep moisture, stage should be set for record low max temps to be set at some locations on Tue. There is also the potential for temps at few locations across nw and n central Upper MI to not get out of the mid or upper 20s F on Tue, which could make max temps on Tue the lowest for so late in the season. Even across the s central, conditions will be unseasonably cold with highs only reaching the upper 30s F at best. -Shsn will wind down/end Tue night as core of the cold air departs. Temps across the interior w should fall into the mid/upper teens F for lows Tue night, which will be in record low territory. Sfc high pres ridge arrives Wed. With a dry air mass and sunny skies, it won't be as cold, but with a gradient wind across Lake Superior ahead of the arriving sfc high pres ridge, high temps will only rise to the lwr 30s F near Lake Superior, particularly from the Keweenaw eastward. Temps should rise to the low/mid 40s F s central and interior w. Shortwave approaching Thu will weaken as it moves thru mid-level ridging. It's quite possible wave will weaken so much that pcpn won't reach Upper MI. If there is some pcpn, ptype could be a mix of -sn/-ra late Thu to early Fri. Next stronger wave will move toward the Great Lakes region over the weekend. With blocky flow and positive height anomalies across Canada into the N Atlantic, this wave should be suppressed on a more southerly track across the CONUS, leaving Upper MI to be affected by the northern edge of the associated pcpn. Compared to the guidance viewed 24hrs ago, 00z deterministic guidance has shifted this wave farther s. Timing onset of pcpn is quite uncertain, no surprise given the time range into the model runs. 00z deterministic guidance delays pcpn onset until late Sat night, but given recent days model runs and ensemble guidance, fcst will reflect pcpn chance Sat thru Mon. Pcpn should be a cold rain given expectation of fcst area being on the northern edge of pcpn shield, but not out of the question that there could be a mix of -ra/-sn at times. Current fcst max temps in the upper 40s to mid 50s F Sat-Mon will be too high if any of those days end up with ocnl rain. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 724 AM EDT MON APR 25 2022 During this fcst period, mid-level troffing over the area along with increasingly colder air will support MVFR cigs at IWD/CMX/SAW, though initially for a few hrs this morning SAW will be VFR. At CMX, cigs may fall to IFR for a time this morning. Otherwise, -SHRA transitioning to -SHSN will increase in coverage during this fcst period, especially tonight when a disturbance approaches. IWD will likely see IFR vis in -shsn overnight tonight. CMX could see vis just as low, but potential is less than at IWD. SAW should remain under MVFR. && .MARINE...(For the 4 AM Lake Superior forecast issuance) Issued at 447 AM EDT MON APR 25 2022 Across Lake Superior, expect w winds to become nw today, then nw to n winds will prevail tonight thru Tue night. Over the west half of Lake Superior, expect winds of 20-30kt early today to diminish to 15- 25kt. Across the e half, generally 15-25kt winds will prevail today, but will increase to 20-30kt toward late aftn. Tonight thru Tue, expect winds generally in the 15-25kt range, but gusts up to 30kt will occur at times across central and eastern Lake Superior, especially this evening and then later Tue aftn. Winds will fall off to under 20kt across the w Tue night, but gusts up to 30kt should continue across the e half of the lake. On Wed, sfc high pres ridge will build se to Lake Superior, allowing winds to fall off to under 20kt across the entire lake. With pres gradient remaining on the weaker side Thu/Fri, expect winds to remain mostly under 20kt both days. With an unseasonably cold air mass moving across the area later tonight thru Tue night, expect some freezing spray at times across central and eastern Lake Superior tonight into Tue evening. && .MQT WATCHES/WARNINGS/ADVISORIES...
