QUICK UPDATE: Prepare for Squalls

So the snow I highlighted yesterday that seemed to "disappear" from the latest model runs actually appeared in the early morning hours. In Canal Winchester, we started as a light freezing rain for only a very short time before changing to sleet, and then snow by sunrise. That was enough to probably bring a quarter inch of snow.

The sun came out for a short time, melting off much of what fell, even though temps continued to drop. Since sunrise we've dropped 6 degrees, with single digit wind chills common in these gusty conditions.

But what we should watch out for this afternoon and in to the evening rush is the possibility of some heavy snow squalls from this fetch off of Lake Michigan. I've highlighted in red the general motion of these squalls this morning, compared to what we should see as the afternoon goes on in green:

As I said yesterday, the conditions are just right with these high winds coming across the lakes and stretching the snow as far as east Central Ohio in to this evening. By nightfall, these winds should back off, and so should the snow showers. Just be very careful headed home today, as these squalls will be enough to bring visibility down to 0 in some places. Bad timing for rush hour.

I'll post tomorrow about tomorrow night's storm.
