Well, you have either a weak battery or poor connections.  You should have
your battery
tested to see how well it holds a charge.   Colder makes it harder for
electrons to move and
so requires a good battery and good connections to make this happen.    All
connections to
and from the battery should be checked.

There is a possibility that the solenoid in your starter may be
malfunctioning in colder weather and
may need to be taken apart and lubed or replaced.    You can check this by
directly connecting
the battery with a jumper wire to the solenoid to see how well it performs
with power directly applied.
All standard warnings apply here and I accept no responsibility for any
injuries following this
advice.....

Hope you find and fix the problem....
