According to Dorothea Pätzold of the DWD, Monday and Tuesday are likely to be rainy, with conditions thereafter described as changeable.
But there is better news in the steadily rising temperatures throughout the week, but that warmth is not here to stay, says Pätzold. She suggests that sun-worshippers will have to keep waiting for that big area of high pressure that might herald a prolonged upturn in temperatures.
Monday should be mostly cloudy with intermittent showers, and maybe even scattered thunderstorms in the north-east as the day wears on. Highs of between 10 and 14 degrees Celsius are anticipated, with the sun even coaxing the mercury as high as 16 in the east. Strong breezes are possible in the south-west and in mountain areas.
Overnight a band of rain thickens towards the east. The temperature will drop from seven to one, with some frost possible in high areas.
The west should see a rainy Tuesday, with thunderstorms forecast in the evening. The east may get away with a cloudy but dry morning, but rain is expected in the afternoon. The south will be predominantly windy. The east will again have the best of the temperatures, with a high of 15 degrees, while elsewhere temperatures will struggle to top 13.
Tuesday night should see the rain ease up and the clouds dissipate. The temperature should drop from seven to two, and could even dip below freezing in the south.
Wednesday should bring thick clouds to the west and north-west. Highs of 14 to 17 are expected outside coastal and mountain areas. The night will see clouds and rain with the temperature dropping from nine to four in most parts – though again the south could be colder.
Most areas will see some showers on Thursday, but the south and east should enjoy some sun too. Temperatures there could touch 22 degrees, but the cloudier north and west may have to settle for 13 to 19. Those areas will probably see rain overnight.
