You are using a wireless system that transmits signals between the outdoor sensor and the indoor receiver. They are not a perfect match. You cannot make adjustments, thus if your lucky, the factory matched up the devices prior to the sale. You may contact Lacrosse for a replacement outdoor temperature device.

My most consistent (best, repeatable) results with this process are to replace both sets of batteries, both in the clock and in the outside temperature sensing unit. Start by removing all batteries out of everything. Now replace the batteries in the outdoor unit, then (within 30 seconds) replace the clock batteries. The temp unit should begin communicating normally within 5 minutes (or less) and yes, you will have to reset the clock,

if it is wireless then check the sender unit
check the battery

severe cold weather can be hard on batteries

I keep the outside unit of our in/out set under a coffee can shaded under a bench; one could argue the aesthetics but shielding it from wind and sun is mandatory otherwise one can get record temps pretty often.
The outside units generally transmit to the receivers only every few minutes to keep battery consumption down so moving them won't necessary gie you an immediate change.
