FXUS63 KMQT 061735 AFDMQT Area Forecast Discussion National Weather Service Marquette MI 135 PM EDT Wed May 6 2026 .KEY MESSAGES... - Benign weather and cooler than normal temperatures continue until the end of this week. Some diurnal rain and snow showers are possible during the daytime hours. && .DISCUSSION... Issued at 139 AM EDT Wed May 6 2026 As we remain under the influence of polar/Canadian air the rest of this week, expect below normal temperatures (similar to what we saw yesterday and what we are seeing early this morning) to continue for the next few days. In addition, with weak shortwave impulses rounding through the region as sfc pressure continues to rise across our area, expect to see some scattered diurnal rain/snow showers across the U.P. today, Thursday, and potentially even Friday as well. Thankfully, no snowfall accumulations are expected as the temperatures and ground should be too warm for anything to stick. Nevertheless, some spots may see up to a trace of snowfall on the grassy sfcs in the heaviest snow showers before the warm air and ground melts the precipitation. In addition to the shower chances, the air at the sfc looks to be quite dry given the incoming sfc ridging from the Canadian Prairies the middle of this week. Thus, while temperatures are projected to only get into the 40s and 50s during the daytime, with dewpoints expected to be well below freezing throughout the next few days, min RHs during the afternoon hours could dip below 30% in the interior areas today and well into the 20 percents Thursday and Friday. Thankfully, because the winds are looking to remain light throughout the next several days and the temperatures are looking to stay below normal (save for potentially Friday and Saturday), elevated fire weather concerns are not expected. With warm air advection moving in on Friday ahead of a cold front descending from Canada, expect the highs to be closer to normal, mainly in the 50s to lower 60s. As the cold front moves through the U.P. Friday night and Saturday, expect rain showers to push through the area, with around normal temperatures continuing through the day Saturday. While not much liquid is expected from the rain showers via the cold front, a few spots may be 'lucky' and get a wetting rainfall (a tenth to quarter of an inch). Behind the cold front, expect more high pressure descending from the Canadian Prairies to bring dry weather and cooler than normal conditions back across the U.P. early next week. Yet even so, the high pressure block that's settled over the Pacific Northwest this week begins to progress eastward over the CONUS next week. As this occurs, we may see a trend towards more normal temperatures and potentially even wetter conditions near the end of the forecast period (the middle of next week) as stronger shortwave or two could impact the area. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 135 PM EDT Wed May 6 2026 VFR conditions are expected to prevail through the 18Z TAF period under cool northwest flow. An embedded shortwave is yielding light snow and rain showers across the UP, but SAW is the only one likely to observe any precip this afternoon. That said, no category changes are expected and accumulation will be negligible. This wave could result in a bit more aggressive north to northeast wind shift at SAW as well then what is reflected in the TAF, but model agreement is on the low side. Otherwise expect W to NW winds to become calm tonight. && .MARINE... Issued at 139 AM EDT Wed May 6 2026 Light winds of generally 20 knots or less continues the rest of this week into this weekend as a stout high pressure ridge over the Pacific Northwest helps keep the weather over the Upper Great Lakes mostly quiet the next several days. Nevertheless, a shot of cold air advection coming down on Sunday could bring northwest winds of 20 to 25 knots back across the eastern half of the lake to begin next week. && .MQT WATCHES/WARNINGS/ADVISORIES...
