Good evening, everyone. I promised to drop by for another update on our increasing chance for the first snowfall of the season. The overall setup has not changed, but as we get closer, the models are obviously seeing things better and they are in pretty good agreement from less than 2 days away.
My overall thoughts have not changed one bit, but my confidence level is increasing a bit as we get closer. A few quick hitting thoughts:
- The arctic front arrives from northwest to southeast Monday afternoon and evening.
- Temps ahead of this boundary can spike to 60 as some rains increase.
- As the front slams through, temps drop quickly through the 30s and into the 20s. That drop in itself can lead to a flash freeze.
- Much of the precipitation with a setup like this falls behind the actual front. That’s where we are likely to find a band light to moderate snow developing.
- A connection to Lake Michigan is likely to show up as well and that can keep snow showers and flurries going into Tuesday across the central and east.
- Accumulations appear to be a decent bet, right now. Coatings to a few inches will be possible, especially on elevated and grassy surfaces.
- Arctic cold settles in for Tuesday and Wednesday with near record lows possible.
I mentioned how the models were showing some pretty good agreement, so let’s take a look.
I’ll start with the Hi Res NAM that only goes through 1am Tuesday…
It’s looking more and more like the first First Call For Snowfall will be needed later tonight or on Sunday.
I’ll see you guys with the regular overnight update. Until we meet again, make it a good one and take care.
