Metro Detroit weather forecast: Much needed 'Irma showers' on the way


What a beautiful day it has been. 

Like Monday, high, thin cirrus clouds made for a very pretty sky and, in some cases, even created some Sun Dogs (I saw one on my drive home from work Monday).  What’s a Sun Dog?  If you’ve ever seen a little patch of rainbow either left or right of the sun (and sometimes both!), then you’ve seen a Sun Dog.  What causes it?  Light being refracted as it passes through those high ice crystal clouds.  The ice crystals act like a prism and bend the sun’s light and breaks it down into its component colors of the spectrum.  They’re pretty cool if you ever see them…especially bright Sun Dogs.  These high clouds will increase tonight, and gradually thicken toward dawn with a very slight shower chance late.  Lows will be much milder than in recent days, with temps only dropping into the mid 50s to near 60 degrees (13-15 degrees Celsius).  Light wind will become calm air overnight.

Expect lots of clouds with a bit of sun on Wednesday.  Widely scattered showers are possible at any point in the day, but today’s models suggest that the best chance is either late afternoon or into the evening hours.  Shower chances decrease the farther north you are in our area, so it’s possible that some of us won’t get any meaningful rain…but keep the umbrella with you just in case.  Highs in the mid 70s (23-24 degrees Celsius).  South wind at 5 to 10 mph.

Wednesday’s sunrise is at 7:11 a.m. (hey, do we get free Slurpees if sunrise is at 7:11?), and Wednesday’s sunset is at 7:46 p.m.

Scattered showers diminish Wednesday night, with lows near 60 degrees (15 degrees Celsius).

Clouds with a bit of sunshine should rule on Thursday, with highs in the mid 70s (23-24 degrees Celsius).

Becoming partly cloudy Thursday night, with lows near 60 degrees (15 degrees Celsius).

The weekend continues to look absolutely spectacular, with mostly sunny skies Friday through Sunday, with highs in the upper 70s (26 degrees Celsius) on Friday, in the low 80s (28 degrees Celsius) on Saturday, and near 80 degrees (27 degrees Celsius) on Sunday.

After a scattered shower chance either Sunday night or Monday, we get into another stretch of sunny warm weather for most of next week!

Hurricane Jose

Hurricane Jose continues spinning its wheels in the Atlantic with 75 mph sustained winds this afternoon…this is a minimal Category 1 storm on the Saffir-Simpson Scale.  The storm is going to do a weird loop before heading northwest toward the U.S., but then turning to the north.  Most computer models keep Jose well off-shore, with the closest call to land being to the Canadian Maritimes.  However, as we saw with Hurricane Irma, there can be significant errors in long-range hurricane forecasts, so the Local4Casters will keep a very close eye on Jose and update you with the latest information daily both on-air and online.
