WEATHER or WHETHER?
I do not know ~weather~ to allow this now (nonstandard).
I do not know *whether* to allow this now (standard).
You use whether when you are talking about a choice or doubt between two or more alternatives.
The ~whether~ was so favourable on that day (nonstandard).
The *weather* was so favourable on that day (standard).
The weather is the condition of the atmosphere in one area at a particular time, for example if it is raining, hot, or windy.
