The NWS has published this outlook for winter in SE Michigan. It’s fairly technical, but they’ve conveniently summarized the important bits for us: December should be roughly normal, and January and February will probably be somewhat colder than normal, though not as bad as last winter.
It’s particularly humid today, and an area of low pressure is moving our way. The upshot of this is that you should expect rain on and off this afternoon into tonight, which might be heavy at times.
Severe weather isn’t expected, but localized thunderstorms might develop. Weather will mostly be moving from south to north.
It has been absorbed by me, Jennifer Sardone (@jmsto) after our fearless leader fled town to live it up somewhere far less interesting. TL;DR version of me: I work at UofM, I’m married to @andrewa2, and we have @shelleythebunny living in our house.
I’ll eventually post real things here – until then, the twitter feed is up and running at @ArborWX.
Happy storm season!
A really great new opportunity has come up for me, and consequently I’ll be moving away next week.
Sadly, this means that I’ll no longer be updating ArborWX. I’ve enjoyed blogging about interesting weather this summer, and I’ll leave the site up for now. I may find someone to take it over, but I have no immediate plans.
Thanks for reading.
Washtenaw County’s emergency warning sirens are tested at noon on the first Saturday of every month from March through September. So when you hear them tomorrow at noon, don’t worry.
If there is a threat of severe weather tomorrow, the test will be cancelled.
Sirens will be activated for the following emergencies:
- The National Weather Service has issued a tornado warning
- A severe thunderstorm has been detected with damaging winds in excess of 70 MPH
- A hazardous materials accident requires immediate protective action by the public
- An attack on the United States is imminent, underway or has recently occurred
Warning siren activation (outside of a test) is a signal to immediately go indoors and monitor local Emergency Alert System media outlets for official information.
NWS Detroit has issued a severe thunderstorm warning for most of Washtenaw County until 5:45pm. This warning is in the path of a storm which developed south of Jackson and is tracking northeast at 28 mph. Hazards from this storm include 60mph wind gusts and quarter-sized hail.
The storm is expected to be near Barton Hills/Ann Arbor at 5:20pm.
I will monitor this storm; as we saw earlier, storms today have been dissipating more quickly owing to the relatively cool temperatures, so this storm may no longer be severe by the times it reaches us.

A severe thunderstorm has developed south of Jackson and will hit Ann Arbor around 5:00-5:10pm. The storm is currently producing 40+mph wind gusts and 1/2″ hail. It is south of Grass Lake, over Napoleon, right now.
The storm is severe-warned in Jackson County until 5pm. It may or may not be classified severe by the time it hits Ann Arbor; I don’t know how much it might dissipate before then. But I do expect to see a decent thunderstorm downtown shortly after 5pm.
I will mostly be providing updates on Twitter (@ArborWX) today.
