Here's the process:
Check yr.no and xcweather. Do they agree?
Yes -> that's the weather
No -> check netweather and a couple others. Was yr just being miserable like always but the others kinda agree?
yes -> that's the weather
no -> roll your sleeves up and get deep into mwis and the weatheronline expert charts linked above to understand the full picture. But to be honest if it's come to this just pack suncream and waterproofs.
