TEMPORARY STOP WINTER: the continuation of the month of December is forced to one pause to reflect induced by the arrival in Western Europe and the Mediterranean of a large cell of high pressure. It will be an initially subtropical anticyclone and then Azorean because the air mass will come in a first phase (Monday-Tuesday) from North Africa and later (between Wednesday and Thursday) from the Atlantic. His ascent to our latitudes will be caused by a large low pressure vortex close to the UK, which will be the dominant feature throughout the week. The activity of this depression will fluctuate slightly towards central Europe, so we expect, within this period, also more stable cloudiness and some phenomena for part of the Peninsula. In particular, between Tuesday and Wednesday, a slight ripple of the disturbed flow will allow a weak disturbance to get to Italy.

MONDAY BETWEEN SUN AND FOG, TUESDAY WITH INCREASED CLOUDS IN THE NORTH: the beginning of the week will therefore be characterized by the anticyclonic rise of a subtropical matrix over Italy. Time will basically be stable on both Monday and Tuesday but with some pitfalls. In fact, on Monday we will have the presence of fogs in the Po triangle with the sun prevailing over the rest of the Peninsula. Tuesday along with the northern mists we will also have a rise in clouds for the transition of the anticyclone from its subtropical state to the Atlantic of the Azores due to the flattening of the zonal flow. This as said will also deliver a slight disturbance which will affect us more directly on Wednesday but will bring increasing clouds to the north as of Tuesday and with the possibility of some afternoon rain in the northwest. From the climatic point of view we will have a temporary one thermal surge mainly in installment on this day of Monday with thermal zeros that can splash even over 3000 m. This thermal rise in altitude will be a danger to the stability of the snow cover accumulated in the last days in the Alps As of Tuesday the flattening of the zonal flow will bring colder currents at high altitudes and the freezing point will fall again.
