What is your favorite weather ro attack in?

[HEMISENT]

I've done 5 or 6 WAW patrols now attacking convoys on the surface in dark, stormy nights, the nastier the better as the escorts have trouble spotting you. I try to set up a 90 AOB attack run cutting across the convoy lanes firing at 500m or less. Makes for some outstanding imersion, also makes for some outstanding repairs when the DD's finally catch up.
