Atlantic low brings mild, rainy week to Bavaria

An Atlantic low named Pia will bring rain and milder air to Bavaria this week, with temperatures reaching 15 degrees in parts of the south and west by midweek, BR reports.

The change follows several days of high-pressure weather, with fog, low cloud and sunshine but little or no rain. On Monday, fog and low cloud will persist in many places before some areas see sunshine. Clouds will spread from the southwest from midday, with rain later in parts of Swabia and Upper Bavaria. Highs will range from 4 degrees in the Fichtelgebirge to 10 degrees near the Alps.

Tuesday will bring mostly dry weather to the north, with some sunshine in Lower and Upper Franconia. The south will be cloudier, with rain at times, though it should become drier and brighter in parts of Lower Bavaria and along the Danube in the afternoon. Temperatures will reach 6 to 12 degrees.

Clouds and occasional rain are expected on Wednesday, with the north likely to receive more precipitation than the south. Under a slight föhn effect, areas near the Alps may see sunshine and remain mostly dry. Highs will range from 6 to 11 degrees, rising to 15 degrees in parts of Swabia and Upper Bavaria. Thursday is also expected to be mostly cloudy, with occasional rain and highs of 9 to 15 degrees.

Rain is forecast widely overnight into Friday and during the day, gradually retreating towards the Alps. Colder air will arrive from the direction of Iceland, bringing highs of just 4 to 9 degrees. By Friday evening, forecasters expect 5 to 15 litres of rain per square metre in northern Franconia and around 15 to 25 litres across much of Bavaria. Totals could reach 25 to 40 litres in Swabia and western Upper Bavaria, and locally 70 litres in the Allgäu and around Lake Constance. The snow line near the Alps is expected to fall to between 1,000 and 1,300 metres by Friday evening.

Conditions are expected to settle over the weekend as high pressure builds from the northwest. The weather should be mostly dry, with some areas seeing sunshine and others remaining foggy or overcast. Light frost is forecast widely overnight, with daytime highs of 3 to 7 degrees.
