FORT WAYNE, Ind. (WFFT) -- We've known for several days now that we would have a weather system impacting the lower Great Lakes region sometime around the start of December, but there were a lot of details to work out: When exactly it might happen? Will we see rain or snow? How much? Well, we now have a better picture as to what that will look like.
While there are still some questions, we know our next weather maker will be in the form of (mostly) snow.
It's made up of two systems moving by us, one from the south that will bring the moisture (big L in the photo below) and one from the northwest that will bring the cold air (cold front in photo below).
There are a couple of different scenarios that could happen. If the system from the south follows a path more along the western red arrow, it could bring more snow to Northeast Indiana and Northwest Ohio.
If it follows the eastern red arrow, less snow (white blob is approximately where the weather system could move).
The system from the NW with the cold air will set in right as the moisture from the southern system moves in.
This means we'll see a bit of rain first before it starts to mix and then transitions to all snow by Monday mid-morning.
The weather maker from the south will slowly move NE on Monday and be positioned over Buffalo on Tuesday, which means the snow will continue to impact us on Tuesday as well.
There is still some questions as to where exactly things set up at the start, but here is our initial snow totals forecast by 7 p.m. on Tuesday, once everything is wrapping up.
As of writing, Fort Wayne will be right around the 2-3 inch mark, with heavier totals to the east of I-69, especially into NW Ohio.
West of I-69 could see a dusting up to 2 inches of snow, with higher amounts up near the lakeshore as NW winds come in off the lake, creating lake effect snow.
Weather models are still in a bit of disagreement as to what exactly will happen, which is why this is the best forecast as of right now.
The forecast for this event and will be fine-tuned over the next 24-36 hours, so make sure to stay tuned to wfft.com/weather for the latest information.
