These are the takeaways from my MLive Morning Weather Update, delivered this morning. In the video, I cover this week’s weather outlook for Michigan, including temperature forecasts, precipitation patterns, and the current flooding situation across the state.
Flooding Rivers Have Crested and Are Receding
All rivers across Michigan that experienced flooding have now crested and water levels are going down, according to the National Weather Service in Grand Rapids. The good news continues with upcoming weather patterns that won’t enhance the flooding situation. While a couple of brief thundershower systems are expected in the coming days, they won’t produce enough moisture to send river levels back up or worsen the current flooding conditions. The downward trend in water levels marks a turning point after the recent terrible flooding that affected multiple areas across our state.
Significant Warmth Arriving Thursday and Friday
Michigan is heading into a notably warm stretch with temperatures flirting with 80 degrees by Thursday and Friday. Thursday’s forecast shows widespread temperatures in the mid-70s, with many locations seeing 76-77 degrees, which typically means some spots will touch 80 degrees. Friday looks even warmer, with Grand Rapids potentially hitting 78-80 degrees. The limiting factor preventing even higher temperatures is the saturated soil conditions from recent rains. While the dark, bare soil would normally help boost temperatures, the waterlogged ground is tempering the warmth. This warm spell will provide beneficial evaporative power to help a little drying of the saturated soils.
Brief Thundershower Activity Expected Today
A quick-moving line of thundershowers is forecast to develop this afternoon across the southern half of Michigan. The activity should begin in the late afternoon from the Grand Rapids and Benton Harbor areas, moving toward the Thumb region in scattered fashion by late evening around 8-10 PM. The line will then shift through the Ann Arbor, Detroit, and Jackson areas. Rainfall amounts will be light, with most areas seeing just a tenth to two-tenths of an inch during the half-hour thundershower passage. Some isolated spots might see three to four-tenths of an inch, but nothing significant enough to impact the improving flood situation.
Friday’s Rain Holds Off Until Evening
Despite Friday being associated with an approaching cold front, the day itself looks to remain dry for most of Michigan. The main precipitation won’t arrive until Friday evening around 8 PM, continuing overnight Friday night into very early Saturday morning. This timing is good news for anyone with Friday daytime plans, as the warm temperatures in the upper 70s can be enjoyed without rain interference. Saturday morning may see some lingering rain that winds down by afternoon, with the rest of Saturday and Sunday appearing nice and dry with good sunshine expected for Sunday.
Omega Block Pattern May Limit Rain Next Week
Meteorological models are showing signs of an Omega Block pattern developing, which could be beneficial for Michigan’s weather pattern. This atmospheric setup features storm systems on either side with a ridge of high pressure in the middle, resembling the Greek letter omega or a horseshoe shape. Michigan appears positioned favorably under the ridge portion of this block. While a storm system is expected Monday afternoon through early Tuesday, the Omega Block pattern should help suppress and weaken subsequent systems moving through the region. This means next week could feature a weakening rain system being impacted by the drying part of the Omega Block.
