As a rule of thumb, after many years of agonising, I have drawn the conclusion that a 3 line taf is never VFR flyable. Stay in bed.
Sounds like a mate of mine who decides whether or not to eat something based on
adding up the E-numbers, and not eating it if the total comes to more than some threshold (his theory being that the higher numbers are newer and/or more obscure chemicals with less of a safety track record).
