You could go to the Weather Channel website and find out what the average weather is on that date.
No way anyone can know this far ahead whether there absolutely will be snow or not. If it’s cold enough, they could at least make their own snow.

When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur?
Question by David O: When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur?
If the force on the tympanic membrane (eardrum) increases by about 1.50 Nabove the force from atmospheric pressure, the membrane can be damaged. When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur? The eardrum is typically 8.20 mm in diameter. Take the density of seawater to be equal 1.03\times 10^3 kg/m^3.

I tried to work out the length of a column of sea-water that is 8.2mm diameter and has a weight (force = mass x acceleration due to gravity) of 1.5 newtons.
The calculation came to 2.81m. That sounds about right, eh?
Working:
1. volume of a cylinder = (area of circle) x (length of cylinder).
2. area of a circle = pi x radius squared
3. diameter = 2 x radius
4. 1 meter = 1000 mm (8.2mm = .0082m)
5. mass of a solid = volume x density
6. force = mass x acceleration (due to gravity)
So:
Force = ( volume of column x density of sea water ) x g
1.5 = (pi x .0082/2 ^ 2) x depth x 1.03 x 10^3 x 9.81
1.5 = 0.533 x depth
depth = 2.81m
