This is the weather forecast for tomorrow morning's destination:

FM1400 06020G32KT 1SM -SN BLSN OVC005
TEMPO 1620 1/2SM SN BLSN OVC002
FM2000 04020G30KT 3SM BLSN OVC003
TEMPO 2024 1SM -SN BLSN


What that tells me is that from 9am (Toronto time) the winds will be out of the east at 20 mph gusting to 35 mph with light snow and blowing snow, reducing the visibility to 1 mile and lowering the height of the clouds to 500 feet above ground. From 11am - 3pm (Toronto time) there will be temporary periods when the snow gets moderately heavy and the visibility is reduced to 1/2 a mile, with the cloud bases only 200 feet above ground. When we leave my destination back to Toronto, the weather is predicted to be pretty much the same, with relatively strong winds, blowing snow, visibilities 1 - 3 miles, and a cloud layer around 300 feet above ground. When we are scheduled to arrive back in Toronto, the weather is also predicted to be snowy and blizzard-y, with similar weather.

If the forecast turns out correct and we get dumped on, it certainly doesn't mean the trip would be unsafe. If it's not safe, we won't go - it's that simple. My passengers trust me to get them from point A to point B in one piece and I take that responsibility very, very seriously. Fortunately, snow isn't dangerous to a business jet while in flight, it's just a pain in the ass to have to look through a heavy snowshower while lining up to land on a runway. Equally fortunately, my employers are great about not pressing the weather, and when tomorrow morning rolls around if it looks like safety would be an issue, I will not hesitate to pull the plug on the trip.

1/2 mile visibility and a cloud ceiling of 200 feet above ground is really no big deal when you're in a corporate jet with decent avionics and using the autopilot to land at a major airport, but it still looks like I'm gonna earn my money.

Having said this, when I wake up tomorrow morning the forecast will have changed, either a little or a lot - it's pretty much impossible to predict exactly how the weather will be 24 hours in advance. But I believe the fine people in the Canadian and US weather centers when they say we are gonna get some serious snow tomorrow.
