Thursday is the beginning of our changing weather. A light breeze will blow ENE at 5-10 mph and there will be no wet weather. We may hit highs in the early afternoon in the middle 30s as skies become mostly cloudy to overcast. We start partly cloudy Wednesday with low-to-middle 20s before the skies begin to fill with clouds through the late morning and afternoon. That system moves south and east Wednesday, just out of our area. This storm is wreaking havoc in the Mountain West and High Plains on Tuesday, with dangerous wind chills of -50 degrees possible, along with snow. Wednesday looks to be another dry one here before a big storm and weather change come to Metro Detroit. Maybe we could all use a little help in lifting our spirits around here this time of year. If those stubborn clouds refuse to break in time, we won’t likely see highs much warmer than freezing this afternoon across our area.ĭo yourself a favor: Once you spot that yellow orb, give yourself a sun break to soak up some of that free Vitamin D, which is good for the body, mind and spirit. A light breeze will move S at 5-10 mph, keeping wind chills in check. Tuesday high temperatures will be highly dependent on that sunshine coming later, because gradual sunshine should help our temps hit the middle 30s or slightly warmer. Look for our skies on this second full day of Hanukkah to go from overcast to partly sunny to partly cloudy through the afternoon. Morning clouds and flurries are stuck over Metro Detroit, and it should stay that way until the middle afternoon Tuesday. We will gradually get into some limited sunshine later today, and you will certainly want to soak any of it up because there isn’t much sunshine filling in the long-range forecast through this holiday weekend and beyond. Some light snow to our west is lifting to the north and east over Lake Michigan and northwestern lower Michigan. The roads are mostly dry, although a few flakes and flurries will be falling here and there in these trapped clouds. Temperatures start in the lower and middle 20s with a light breeze creating wind chills in the upper teens for a few hours. Stay tuned to Local 4, and the Local4Casters weather app for the very latest.It’s cloudy and cold all over Metro Detroit today. But I want you to be aware of the very real possibility of a high-impact winter storm midweek so you can make preliminary plans to work from home if possible, for childcare if there are snow days Wednesday and Thursday, and to have a full tank of gas and gas for your snowblower (or cash for the kid down the street you pay to shovel your driveway). By the way, another sharp blast of Arctic air will follow this storm next Friday and Saturday.Īgain, the small thermodynamic details that I need to fine tune the part of the forecast that’s most important to you are very tenuous this far in advance with a storm like this. That could be the difference between a six-inch snowfall and a 10-inch snowfall. One of the biggest uncertainties is if the band of snow will continue throughout the entire day Thursday, or sag south of us and give us little additional snow. However, some of the snow could be moderate to heavy and, by Thursday morning, we could have 6 inches of snow on the ground, with more to come. I want to emphasize that it will not snow heavily the entire time. I suspect areas northwest of a line from Port Huron to Jackson will be all snow by dawn Wednesday, with the rest of the area changing over during the morning.įrom that point, it appears we’ll have a long-duration snow event, with the snow not abating until sometime Thursday. One detail I have only modest confidence in is the exact timing of the changeover. But as this rain moves in, cold air will be moving southward, which will cause a gradual changeover from rain to snow. Rain or rain showers will develop late in the day Tuesday, or Tuesday evening. So, with the understanding that things could change, here’s how I see it playing out. It won’t be until it crosses the West Coast and moves over the continent that our land-based weather balloons can provide data that is then ingested into our computer models. The reason for this is that the upper-level system that will generate this storm is still out over the data-poor Pacific. DETROIT – Here’s a quick update on this week’s storm, which I’ve been telling you about since last Wednesday.īefore getting to the forecast, I want to caution you that there are some important details that won’t be known with any confidence for another day or two.
