Tomorrow through Poland will pass a dangerous low named Joachim. It will change the weather in the form of a very strong wind and heavy rain. Significantly the temperature will decrease which in the recent days was very high for December.

Latest forecasts have changed significantly when it comes to the weather in Poland tomorrow and not only. Primarily forecasted wind will be much stronger, especially in the south-west part of the country. At the height of 850hPa wind has to speed up to 75kt what near the earth's surface can give gusts achieving 100-110km/h. Above the rest part of the country it will blow a litte weaker but still strong - we expect gusts to around 80-90km/h. Apart from that it will be also raining heavily, especially in the western and southern districts. Responsible for this all will be low named Joachim, which will pass over the northern part of the country at night from Friday to Saturday.
