Additional modifiers for extreme cold?

Not really. Hypothermia isn't an "instant" effect, unless you've got a heavy wind (in which case the soldiers aren't fighting in -40 degree wind chill, they're in bivouac). It wouldn't take as long as fifteen minutes to be affected, but it wouldn't hit them at once.

Granted. However I was thinking even if it’s not instant, there would be at least a penalty to the HT roll if things were more than “chilly”. Though the interval is also debateble. After all if 30 minutes becomes 15 minutes in “light wind” isn’t it because the wind chill is stripping heat away? Wouldn’t colder temperatures even bereft if w8nd have a similar impact?

Also, would wet clothes increase the temp threshold for HT rolls? In other words, would rolling at -5 in wet clothes at 30 degrees be equal to say an unmodified roll in wet clothes at 50 degrees?

There is a modifier for more extreme temperatures - on the table (B430) it gives a -1 to HT checks for ever 10 degrees below 0 (Fahrenheit, I assume).

The initial immersion might attract a HT roll for thermal shock, but that shouldn't be ongoing if the victim was merely dowsed in water (but it is a guaranteed loss of 1FP, possibly rather more for average characters).

It's weird for the scale of penalties to go from 35 degrees to 0 degrees and then vary by every 10 degrees.

In temperature, there's little need to convert anything, so it doesn't have any benefit from power of 10 conversion. The difference is pretty much entirely familiarity. You could even make a case that Fahrenheit is better suited to environmental temperatures, where less than 0 or more than 100 are dangerous extremes.
