Really it is not cold enough here for that effect. Usially the light pillars appear at around -20°C and below. You need low temperature to form flat or needle-like ice crystals instead of regular showflakes or round frosen droplets and steady air to allow them to align horisontally. Now it is near +10°C and windy all over mentioned regions.
I often saw light pillars in winter, but never saw them in other seasons. It is a good winter temperature detector, if you see them from your window - it is definitely very cold outside. But that's not the case now. So it is unusual phenomenon, whatever it is.
