This morning I would have said we were changing our design to a snow plow.

Now the weather looks like the 'snow' will come a day early when it's warm and thus be mere rain.

Weather presents the major risk with attempting anything mildly complex using in-house machining - we have the schedule, labor, tools and skill - but for at least 1 week every season we don't always have weather on our side.
