Detroit – How about that sunshine! Even when it’s cold, a day with blue skies and sunlight sure makes a difference here in the winter, when cold air circulates across Lake Michigan usually creating a lot of cloud cover.
We’ll keep mostly clear skies until evening, with clouds returning later in the night. Temperatures will drop until the clouds move in and then rise a little later. So how low we go will be determined by the timing of withdrawal, and at this point, my thinking is that we’ll bottom out in our low teens (-11°C). Southeast winds will turn south at 5 to 10 mph at dawn.
Sunset this evening is 5:34 PM and sunrise on Saturday is 7:55 AM
Saturday starts mostly cloudy, and we’ll periodically start light snowflakes early in the morning for some of us, and last into the late afternoon or early evening. My expectations remain consistent with what I’ve told you over the past days: I think we’ll only see a few tenths of an inch of buildup if that is. It’ll be noticeably breezy during the day, with southerly winds of 15 to 20 mph reaching 20 to 30 mph during the afternoon. These southwest winds will raise temperatures into the high twenties (-2°C), but, as you know, the winds will make the weather much colder.
Any remaining flashes will expire on Saturday evening, and the rest of the night will be cloudy but dry. The only possible exception is the chance of some late-night chips south of I-94, which could extend into Sunday morning if it develops. Lows in mid-adolescence (-8°C).
It looks like cloud cover will separate from north to south during Sunday, so hopefully most of us get some sun from the deal. The highlands are in the mid-twenties (-5 to -4 degrees Celsius).
Clouds increased Sunday night, with lows in the low to mid-teens (-10 to -9 degrees Celsius).
While there are still some fine-tuning details unresolved, some computer models come to general agreement for Monday’s storm in that the same low pressure area will track east through central Michigan – north of our region. As such, the snow that we get here in southeast Michigan will result from the leading edge pushing warmer air in front of the system, so once it develops, which should be late in the morning, big snowflakes will grow — they’ll be lovely to watch.
Monday morning rush hour will be dry, but it will be a slower afternoon rush hour, with snow not diminishing until Monday evening. At this point, I expect an overall 1 to 4 inches of snowfall across southeastern Michigan, with the lowest amounts near the state line, gradually increasing to higher amounts in the thumb.
Monday’s highs should approach 30 degrees (-1 degrees Celsius), but don’t get used to it as more arctic air arrives behind this storm system.
