h.sie, I spent a day trying out your mod.
I'm using LSH3 V5.1 as my basic mod. Went out for a 2 months trip to Canada near Halifax in Aug, 1941. Had no probs. And weather changes even at 4096 tc. My impression was that I didn't have long term bad weather periods lasting for 4 weeks and longer. Even the 15 m/s winds didn't show up so often. Often the wind was blowing between 0 and 7 m/s. And only sometimes, for not so long as usual, blowing over that.
One thing I realized: Asking for Weather Report, what I did very often (poor devil having to do that over a hunded times a day

) it showed thick fog and no rain, but it did rain, I saw it! But that's all. Verry good work.
Your mod is sticky in my mod collection! Hope it will leave Beta-Status some day
Cheers
Schmutt
