Weather: HALLOWEEN Bridge and OGNISSANTI Surprising, but then you risk an early winter. Trend for November
First advances for Halloween and All Saints’ Day Amazing Halloween and All Saints’ Bridge. The autumn confirms one season of extremes and the period between late October and early next month November It will certainly not be an exception, indeed let’s get ready for many surprises. Nothing extraordinary or anomalous, let’s be clear: in this time of year it is not at all rare to go from warm sunny days to extreme situations, such as floods (which unfortunately we have already experienced in this beginning of October) up to an early winter advance with even the first snowfall at low altitude.
The novelty that emerges from the study of the latest updates in view of the end of October is the resumption of the Atlantic disrupted flow in a big way. According to the American GFS model, a large area of low pressure will form between the British Isles and Greenland, called in technical terms Depression of Iceland, which will pilot several times the perturbations towards the old continent. One of these is just waiting for the party of Halloween (October 31) and the subsequent celebration of All Saints when the weather conditions could abruptly worsen starting from the North West regions. Subsequently the bad weather should extend to the rest of the country with the possibility of the formation of a insidious Mediterranean cyclone: these atmospheric structures can persist for several days, causing heavy rains with cumulative of over 2/300 liters per square meter in no time e storms along the coasts more exposed. In this context, temperatures would also suffer a decisive backlash under the pressure of the cold currents descending from Northern Europe.
And what about the snow? Only in the end of the month the trend, and this is the surprise of the latest seasonal update, it is veering towards an early winter, with gradually lower temperatures and with average rainfall. If this is confirmed, it is reasonable to expect the first snowfall of the season as far as hilly shares, prelude to a winter that at that point will be almost upon us.
