The new month started in the southern regions of Piedmont the way February ended: with fresh snow. Locally, the amounts were already staggering, but since yesterday afternoon it has started snowing again. In the coming days, it will remain mainly dry, but a transition to a north-westerly flow early next week and a weakening high-pressure blocking will cause increasing changeability.
In areas such as Prali and further south, snowfall last night brought about 20-30 centimetres. At the moment it is still snowing a bit, but during the day the snowfall will decrease again. Tomorrow, the flow temporarily turns to the northeast, meaning the northern Alps will again face more cloud cover. This may include some light snow, but it will not bring much anyway. Saturday the sun returns, but on Sunday new clouds with some light snow will follow from the north.
For next week, the weather models are now showing interesting calculations. Increasing low pressure over northern Italy may first bring some snow in the south-eastern Alps on Monday, but the real work seems to be following for the (north) western Alps for several days already. First of all with the depression we see over the North Sea in the map above. The core is deepening considerably and cold air is flowing into central Europe on the western side of the depression. Whether the Alps will also be affected is not yet certain, but quite a bit of snow could possibly start falling in the French Alps and west side of the Swiss Alps from Tuesday, but for details on this snowfall it is still too early.
In the following days too, the changeability seems to persist. With no high-pressure blockade to our west, Atlantic depressions can reach the Alps more easily. How exactly this will happen and what it yields is still uncertain, for instance the snowline could possibly still be a tricky thing in this succession of depressions from the west, but at least it is good news for the north-western Alps, which can expect quite a bit of fresh snow in this weather setting. The ensemble for Geneva shows well why I cannot going into details yet. With the increasing variability (see the precipitation signal), the spread of the ensemble also increases considerably. Other models also still show some differences.
