propitious

from The American Heritage® Dictionary of the English Language, 5th Edition.

• adjective Presenting favorable circumstances or showing signs of a favorable outcome; auspicious.
• adjective Merciful or kindly.

from The Century Dictionary.

• Favorably disposed; ready to grant a favor or indulgence; kind; disposed to be gracious or merciful; ready to forgive and bestow favors.
• Affording favorable conditions or circumstances; favorable: as, a propitious season.
• Synonyms Gracious, benign.
• Auspicious, Propitious, promising. Auspicious cannot be safely used in any meaning beyond that of giving omen or indication of success; an auspicious event is one that seems an omen of prosperity for that which follows. Auspicious could be applied to a person only by a highly figurative use of the word. The earlier tendency to use the word outside of the limits here indicated is not now sanctioned by good usage. Propitious applies primarily to persons, but may be freely extended by figure to things. Propitious goes beyond auspicious in representing a benign disposition and manner, leading one to expect a kind reception and help.
