I've been monitoring the weather in prep for my trip and had become a little dismayed a heat wave was being predicted.
Obviously not an actual heat wave but temperatures above 32F/0C in conjunction with precip, meaning rain. RAIN when trying to enjoy a large Christmas market. RAIN when catching the nativity scenes and carolers advertised on Krakow events sites. RAIN when slogging through Auschwitz (OK, maybe a day in Auschwitz deserves to be as miserable as possible!).
Every few hours I check, and every time the weather report changes. Guess we'll just take what we get!
But all the forecasts seem to agree it will be snowing on Christmas.
