This is the final Winter blog of the season, It has been an historic winter in recent years, with very large snow amounts which have lasted for much of the season.
I will continue to post updates in the Main Skiing blog, https://www.netweather.tv/forum/topic/88719-worldwide-mountain-snow-sports-discussion-201718/?page=13 , but not to the extent of these blogs, and with the Easter break being earlier than usual, it seems a good time to end them for the season.
We are now very much into the end of March and while on piste conditions remain generally very good or excellent. Into the afternoon slopes will become slushy or have spring skiing conditions especially on lower and southern facing slopes.
Off piste conditions remain variable and there remains the risk of avalanches.
Next weeks conditions are very much late March with large temperature changes, these perhaps changing by over 10c day to day at times.
This week is very much dominated by low pressure systems moving Eastwards over Northern mainland Europe.
To start this weekend Low Pressure is centred North West of the Alps, with South Westerly winds over the Alps. As the Low Pressure moves Eastwards by Sunday, the winds turn Northerly on the back edge of the Low Pressure system, so turning colder.
Monday sees a ridge of High Pressure, so drier but still remaining cool.
A rinse and repeat pattern for mid-week onwards. Low Pressure is centred North West of the Alps, with another mild SW flow over the Alps, with 850Hpa over 10c over some areas with a localised foehn wind.
Turning cooler/colder once again by the end of the week, As the Low Pressure moves Eastwards for later Thursday into Friday.
So very much a rollercoaster of temperatures and airmasses this week, with exact timing always flexible.
Rainfalls / Snowfalls
For the weekend, this Low pressure in the vicinity of the Alps means unsettled conditions with widespread precipitation at times, this concentrated in southern areas on Saturday, before moving away to the East late Saturday.
As the winds move to the North on Sunday, the precipitation becoming restricted to Northern areas of the Alps, turning drier into Monday and early Tuesday as a ridge of High Pressure moves in.
For Tuesday further precipitation ending in but this largely restricted to South Western area, with other parts staying dry. Wednesday sees this precipitation become far more widespread over the Alps, with heavy bursts in places. This steadily moving East overnight into Thursday with the precipitation becoming concentrated over Northern parts and Austria, this clears away later. Residual precipitation continues over Northern parts of the Alps, before becoming drier for Friday for all parts.
For the first event, Snowfall restricted to 1500m upwards to start this dropping back to around 1000m behind the front as it edges Eastwards. 50cm of snow seems likely in a number of spots, with close to a metre of snow possible in isolated locations over 1500m.
For the 2nd event, there is much milder air associated, so any snowfall initially reserved for over 2000m for Wednesday, this dropping back to over 1500m during Thursday, and finally to around 1000m on Friday as the winds veer Northerly. 50cm of snow seems likely in a number of spots, with close to a metre of snow possible in isolated locations over 2000m. However large falls of rainfalls are far move likely below 1500m.
So for the final blog of the season, another mixed week with some snow at times. As mentioned above forecasts will continue in the main thread, with the Ski blogs returning in December 2018.
