You may find http://ielogical.com/Audio/WinterBlues.php interesting and specifically http://ielogical.com/Audio/WinterBlues.php#TheFly for the effect of temperature on speaker XOver
You did not mention the source. LP playback systems are subject to all manner of temperature related foibles: bearing tolerance, lubrication viscosity, cantilever suspension compliance, vinyl plasticity.
Do you note levels at which you play a particular piece?
How repeatable is your level control?
When mixing, we calibrated the playback level to the speakers to ±0.1db. The room was temperature controlled to ±1.0°F. When we were satisfied, we always checked the next day on cold monitors. Mixes made in the heat of summer sounded different even though the room temperature was nearly identical as rooms were not humidity controlled. Line voltage and dirt varies considerably in Los Angeles, so we recorded and mixed late a night when the vagaries were minimized.
