No.
Water in the form of clouds, rain, snow, do not appreciably
degrade GPS signal reception. Water in/on foliage, or standing
water(drops or film) on a GPS receiver's antenna, or on a 'holster'
used to carry a GPS(if it covers the antenna) can degrade signals.

If you don't know about 'the other GPS newsgroup', take a look
at the GPS page on my website.

You can use Google to find posts that various people have made in
the GPS newsgroups about using GPS receivers in snowy conditions
such as skiing or snowmobiling, and I recall at least one posting
referring to receiving signals in a snow cave.

The GPS signal won't be affected by snow, but the display and
batteries could be affected by real cold.

The display can lose its contrast to the point that the unit can look
as if it's not powered on, and adjusting it won't have much effect.

Lithium (aka "Photo-Lithium") batteries (non-rechargable, sorry) will
function undeterred to about 40 degrees below, so at least have a set
stashed in your pack.
