Metro Detroit weather forecast: Chilly start this weekend
Can we see tonight's Orionid meteor shower?
DETROIT – Chilly air, brisk breezes and even a few sprinkles and light showers blowing in off of Lake Huron (affecting mainly parts of our northern and western zones) certainly made you take notice today as we now return to some real fall weather instead of the abnormal 70s and 80s we had mid-week.
Showers and sprinkles will gradually end tonight, and skies will eventually clear (those of us in the Thumb will be the last to see things move out -- it may take most of the night).
Lows are forecast to drop into the mid to upper 30s (that’s 2-3 degrees Celsius for our Canadian friends using the metric system). I’m not expecting widespread frost due to a northwest wind at 7 to 12 mph. If the wind were to go totally calm tonight, then I think a lot of us would see frost, but the wind should keep the lower atmosphere mixed enough to prevent the additional cooling we’d need for frost.
The highest risk for frost tonight is in our west zone, as the wind there will possibly be lighter than areas farther east.
Fortunately, skies should be clear later, because tonight is the annual Orionid Meteor shower. The earth will be passing through dust left behind when Halley’s Comet comes through every seventy-six years, and those bits of dust (most are the size of a Grapenut cereal grain) are what enter our atmosphere and "burn up" due to friction.
The best time to see the Orionids is before dawn Saturday morning, so this is another one of those meteor showers that favors early-risers. Just face the east-southeast looking toward the constellation Orion -- that’s where the meteors should originate, and that’s also why they’re called the Orionids. Tweet me (@PGLocal4) if you see any.
Mostly sunny to partly cloudy skies are expected on Saturday, with highs in the low 50s (11 degrees Celsius), although a brisk west wind at 10-20 mph will make it feel colder. Dress warm if you’re heading to the Big House for the Michigan game. Go Blue!
Saturday’s sunrise is at 7:55 a.m., and Saturday’s sunset is at 6:40 p.m.
Skies should be mostly clear Saturday night, with lows in the low 40s (6 degrees Celsius).
It will be partly cloudy on Sunday as a weak upper-level disturbance crosses northern and central lower Michigan. I think any showers associated with the disturbance will stay north of our area. We’ll see a nice warm-up, though, with temperatures reaching the low to mid 60s (17 degrees Celsius). It wouldn’t be such a bad idea to get a leg up on your yard work this Sunday.
Partly cloudy Sunday night, with lows in the low 40s (5 degrees Celsius).
Partly cloudy on Monday, with highs in the mid 50s (12-13 degrees Celsius).
Mostly clear Monday night, with lows in the mid to upper 30s (2-3 degrees Celsius).
Mostly sunny on Tuesday, with highs in the mid 50s (12-13 degrees Celsius).
Mostly clear Tuesday night, with lows in the low 40s (5 degrees Celsius).
Increasing clouds on Wednesday, with highs again in the mid 50s (12-13 degrees Celsius).
Then, rain is likely Wednesday evening into Thursday, with highs Thursday in the upper 50s (14-15 degrees Celsius).
Today’s long-range maps still suggest a dry Halloween for the Trick or Treaters, with seasonably cool evening temperatures in the mid to upper 40s (7-9° Celsius). We’re still ten days out, so things can still change, but I’m encouraged that the pattern I’m seeing in the models has remained relatively stable through the week. I’ll be a lot more confident about this next week (unless things suddenly change).
