Ice In

Emerson didn't need to call Ice In in the past because it ALWAYS froze by the beginning of Jan, sometimes earlier.
Just saying

It usually was around the third week of Jan before the broads were all frozen in.

Looks like the lake is iced back in again...

First reason to stick with the current method is consistency. If you change how you measure ice in and out then you can't compare dates anymore. Second is that this is simple, ice in is when the whole lake is covered, ice out is when all the ports are free. It's easy to check both. If you made ice-in when the ports are iced then you could get ice-in from a cold snap and then ice-out the next day when a warm wind turns up. The events that bracket the iced in period have to be well separated. There needs to be hysteresis.

When I was a kid, I was out snowmobiling across the broads by the 2nd/3rd week of Jan, usually ice skating off the beach New Years-ish. It's been later and later each year until we finally got rid of the snowmobiles mid 90s because we didn't use them enough because the ice was in later and less snow.
