The weather in Holy Week until Good Friday is very mixed: After a fairly sunny start with a foehn on Tuesday in the northern Alpine valleys, it will be unsettled on Wednesday and Thursday and partly wet, especially on Wednesday. Rain is already falling in the south on Tuesday. On Good Friday, it will remain dry with foehn winds in the north and some sunshine, especially in the east, but it will be cloudy and repeatedly wet in the south. The Easter weekend in the north will be dominated by the foehn wind with friendly weather and very mild to warm air, while in the south it will often be rainy with congestion. On Easter Monday, it is also likely to be wet in the north as the foehn breaks down.
Further heavy precipitation during the day today, Easter Monday
Today, Easter Monday, there was heavy precipitation during the day, especially in the south and in the neighboring areas to the north, with totals locally exceeding 30 mm (see table below). There were also local thunderstorms, especially in Ticino.

In Mosogno, 20 mm were added, resulting in a total of 275 mm since Good Friday, in Robiei it was 16 mm, here we are at 232 mm.
The heavy precipitation event in the south will come to an end in the evening, and it will remain mostly dry during the night and tomorrow (Tuesday).
Balance on Easter Monday morning
Although the precipitation event in the south on early Easter Monday morning is not yet completely over, it is already worth taking stock of the precipitation since Good Friday morning. As predicted, the main focus over the past three days has been from northern Ticino to the south side of the Simplon. Mosogno is in first place by a clear margin, with 255 mm of rain falling here so far! But Robiei and Bosco/Gurin have also exceeded the 200 mm mark. To put this into perspective, the long-term average for northern Ticino is 100 to 140 mm of precipitation throughout March. The almost 160 mm of rain in Locarno also clearly exceeds the March norm (96 mm). A final summary of the precipitation will be published here this evening.
Amount of precipitation (as of 07:00)
A last rebellion of the Föhn
After a brief period of weakness in the night before Easter Sunday, the Föhn made another impressive comeback over the course of Easter day. Once again, wind speeds of well over 100 km/h were measured in the Alpine valleys. For example in Meiringen with 117 km/h or in Bad Ragaz with up to 110 km/h. On the mountains, the highest gusts of over 150 km/h were recorded on the Titlis (158 km/h) and on the Gütsch (154 km/h).

Foehn storm yesterday Saturday, southerly wind storm on the mountains
Yesterday, Saturday, a Föhn storm raged in the Alpine valleys and there was a stormy southerly wind on the mountains (see Fig. 2). The highest wind speed in the mountains was 173 km/h on the Gütsch above Andermatt, while Bad Ragaz and Altdorf led the way in the valleys with 107 km/h.

Stormy Föhn again today, Easter Sunday
After the Föhn weakened during the night with a disturbance and even collapsed in places, it is blowing through the Alpine valleys again today (Easter Sunday) and in the night to Easter Monday. Local wind speeds of just over 100 km/h are possible. Towards Easter Monday morning, the Föhn will then break down and the exceptionally strong and long Föhn phase will come to an end.
Update on wind peaks on Holy Saturday morning
Yesterday evening and during the night of Holy Saturday, a stormy foehn or gale-force south wind continued to blow on the mountains. Some of the wind peaks since the last ticker update on Good Friday evening (see below) were exceeded again. The 190 km/h on the Gütsch above Andermatt are particularly impressive. If this is not a measurement error, then this would be the second-highest measured value at this station since measurements began in 1981. The record dates back to March 22, 2001 and is around 193 km/h.

Stormy foehn and Sahara dust
Strong to stormy southerly foehn winds blew in the Alpine valleys today, Good Friday. In Altdorf, a gale-force gust (= gusts from 118 km/h) of an impressive 130 km/h was even recorded! But Meiringen, Altenrhein and Chur also experienced gale-force gusts. It's also stormy on the mountains, with gale-force gusts measured at several measuring stations since yesterday Thursday evening.

Strong to gale-force southerly foehn winds will continue during the night before Holy Saturday and on Holy Saturday, although they are likely to be a little weaker than today (Good Friday). However, gale-force gusts are still to be expected, especially in the Uri and Hasli valleys! Details can be found in the warnings.
In addition, a good portion of Sahara dust has already reached us during the course of today and it has become increasingly hazy (see Fig. 1). Tomorrow, Holy Saturday, there will also be a lot of Sahara dust in the air, so there will be pale sunshine at most and the color and light mood will also be affected.

Already a lot of precipitation in the south in the last 48 hours
A lot of precipitation has already fallen in the south in the last 48 hours, locally up to over 50 liters (see Fig. 1).

As the precipitation cooled yesterday, the snow line dropped as far as the northern Ticino valleys and the southern Grisons valleys.
Over Easter, there are still frequent wet conditions in the south with very large amounts of precipitation in total with lots of fresh snow on the higher mountains and a high avalanche risk in some places. Read more here.
On Tuesday, partly stormy foehn in the Alpine valleys during the day as well
During the day, the northern Alpine valleys were also affected by a partly stormy foehn wind, with gusts in many places slightly higher than last night. It was also stormy in places on the mountains with local south wind gusts of just over 100 km/h (see table below).

Spring-like mild in the north
It was much milder in the north today (Tuesday) than in the last few days, with widespread spring-like temperatures of 15 to 18 degrees. In the cloudy and increasingly wet south, however, it remained much cooler at around 11 degrees (see Fig. 1).

Foehn during the night, then foehn end
During the night, the foehn will still be blowing strongly to gale force in places, then break down tomorrow morning with a cold front . The next foehn phase will then follow from Good Friday.
Partly stormy foehn during the night to Tuesday
Yesterday, Monday, the difference in air pressure between the north and south increased more and more, so that it became increasingly foehn-like in the northern Alpine valleys (for the development of the foehn, see here). We use the pressure difference between Zurich and Lugano as a measure of the strength of the foehn (see Fig. 1). If the air pressure in Lugano is higher than in Zurich, we speak of a southerly overpressure, i.e. a southerly foehn. The opposite is the case with a northerly foehn. From a southerly overpressure of approx. 3 hectopascals, foehn often occurs in the upper Rhine Valley, for example. However, depending on the specific weather situation, the foehn can also occur at a lower pressure difference or even fail to appear at a higher pressure difference. In addition to the pressure differences at low altitudes, the direction and strength of the high-altitude winds are also decisive (southerly winds support the foehn, westerly winds do not). The greater the difference in air pressure between north and south, the greater the likelihood of a foehn, the stronger it will be and the further it will extend towards the Central Plateau.
Fig. 1: Air pressure difference between Zurich and Lugano as a measure for estimating the foehn probability and foehn strength; Source: MeteoNews, UBIMET
The foehn continued to intensify overnight today (Tuesday) and blew through the northern Alpine valleys, sometimes with gale-force winds. There were local wind speeds of over 100 km/h, as the table below shows.

Today, Tuesday, the foehn continues to be stormy in places
According to Fig. 1, the pressure difference continues to increase, which means that the foehn will tend to get a little stronger and move further towards the Swiss Plateau. Gusts of up to over 100 km/h are still possible, especially in the Hasli Valley and Uri. In the afternoon, the foehn may then extend far into the Central Plateau and will probably also blow at times in Lucerne and on the Zürichberg. In the long term, the foehn only blows a little more than four times a year as far as Lucerne and even less on the Zürichberg, namely around twice.
Fig. 2: The Föhn is probably also blowing intermittently on the Zürichberg this afternoon; Source: roundshot
On Tuesday night, the foehn will initially blow strongly to gale force through the Alpine valleys, then gradually weaken by the morning. In the course of tomorrow morning, it will then break down with the arrival of a cold front.
Foehny Easter days
From Good Friday to Easter Sunday, the foehn will be a frequent guest on the northern slopes of the Alps, sometimes blowing gale-force winds through the Alpine valleys, with gusts of around 100 to 130 km/h, possibly even higher locally. In addition, there will be a partly stormy southerly wind on the mountains. At times, the foehn is likely to extend far into the Central Plateau. It will only weaken in the night before Easter Sunday, but will then pick up again considerably over the course of Easter Sunday. A cold front is then expected to put an end to it during Easter Monday, bringing the long and strong foehn phase to an end.
Today Monday quite sunny
After the cool, windy and April-like weather at the weekend, the weather today (Monday) at the start of Holy Week will be fairly sunny and slightly milder than at the weekend. There will only be increasing clouds from the west during the day. After a very cool morning with quite widespread frost on the ground and locally light frost in the huts, temperatures will reach around 11 to 14 degrees in the afternoon with a light breeze, with 15 to 16 degrees possible in the south.

A foehn and friendly Tuesday in the north, wet Tuesday in the south
Tuesday will bring a foehn and friendly mix of sun and clouds in central and eastern Switzerland. There will be Sahara dust in the air. It will be much milder at around 14 to 17 degrees, with strong to stormy foehn winds in the Alps with gusts of 70 to 110 km/h. There will be more clouds in the west, the sun will only rarely appear, but it will remain largely dry until the evening. In the south, dense clouds will accumulate, with some rain falling at only around 10 degrees and flakes from around 1000 to 1500 meters (see Fig. 2).
Fig. 2: Weather tomorrow Tuesday; Source: MeteoNews, UBIMET
Cold front on Wednesday
The Föhn will break down during the night to Wednesday, and during the day a cold front will move from west to east with freshening south-westerly to westerly winds. After the last clear spells, it will be cloudy and occasionally wet in the far east. The snow line will drop to around 1000 meters with temperatures of only 6 to 9 degrees in the afternoon. In the west, the clouds will clear again in the afternoon or towards the evening at around 10 degrees. In the south, it will be cloudy and often wet with heavy precipitation at around 8 degrees. Snow will fall in southern Ticino from around 1000 to 1500 meters. In northern Ticino it may snow well below 1000 meters with heavy precipitation!
Another weak front on Maundy Thursday
After the weather calmed down briefly, the next, albeit weaker and only narrow, disturbance will pass over us on Thursday. There will be occasional showers, especially in the east in the morning and some sunshine in the west during the afternoon. Temperatures will reach around 9 to 12 degrees in the north, with slightly higher values in the south.
Easter weather: Often wet in the south, friendliest in the east with a foehn wind
The weather over Easter is not easy, as we are close to an air mass boundary that separates warm air in the east from cooler air in the west. What is clear is that we are in the area of a south to south-westerly current that accumulates moist air on the southern slopes of the Alps. From Good Friday to Easter Monday, the weather will clearly be at its worst here, mostly cloudy and repeatedly wet with heavy rain in places and total precipitation amounts of up to well over 200 liters per square meter (see Figs. 3 and 4). The most precipitation is likely to occur on Easter Sunday night and Easter Monday. Temperatures are expected to reach between 12 and 15 degrees. The snow line will mostly be between around 1500 and 2000 meters, with intense precipitation, especially in the valleys, it may snow further down. It's harsh to say, but it's definitely not worth traveling south for Easter in terms of the weather!

The friendliest weather will be from Good Friday to Easter Sunday with occasional foehn in the Alpine valleys in the east. However, it is difficult to estimate how much sunshine there will be, as there will be Saharan dust in the air again over the Easter weekend, which will encourage the formation of clouds. It will also be mildest in the east, with maximum temperatures likely to be between 15 and 20 degrees from Good Friday to Easter Monday. On Easter Saturday, temperatures of just over 20 degrees are possible in the east and in the Alpine valleys. On Easter Monday, the Föhn is likely to break down, meaning that it will probably be wet from the west and south.
A more detailed Easter forecast will follow here next Wednesday.
Finally, an overview of the weather forecasts from Wednesday to Easter Monday (see Fig. 5).
