April weather is expected to provide a total of five millimeters – Barometer-OT

What we can hope for the coming week is April 1 weather with some local showers here and there, which in total gives a handful of millimeters of rain, maybe five. The weather next week until Wednesday it is difficult to assess, but gets low pressure stressed.

It hardly seems to be the 100 millimeters of rain that Bo Thunholm, a geologist at the Geological Survey of Sweden, Geological Survey of Sweden, in the media in recent days spoken out about the need to bring up the groundwater levels to normal levels again from today’s very low.

They are notoriously at a historically low level due to frequent mild weather and drought since last autumn, bad with snow in winter and a meager supply of water from snowmelt.

How much is a proper rotblöta measured in millimeters of precipitation?

– It varies widely, and are difficult to answer, says Sofia Soderberg, a meteorologist at SMHI in Norrköping.

– the ground must also be able to absorb rainfall. It depends on whether it is dry when the rain comes or if it is saturated and rainfall therefore not flow down, but instead brings flooding, she continues.

As a comparison, she mentions the limits SMHI has to issue warnings for difficult weather.

– about 35 millimeters of precipitation expected over a larger area in the next twelve hours issued a class 1 warning.

class 2 warns of about 70 millimeters or more expected over a larger area the next 24 hours.

– Recently we have introduced warning for local risk. Then it can be about local, sharp bursts of 50 millimeters for a short time in a limited area.

The closest happening with the weather is that a low-pressure front with rain to pass Götaland.

– in the southeast the country can get ten millimeters locally in small areas. Broadly, in the area may in the near future to get a total of up to 5 millimeters of precipitation.

From Thursday there is a weather change but the situation is difficult to assess. Something rainfall area for a long time makes a lot of rain is not in the forecast.

– It’s a long way up to 100 millimeters, says Sofia Soderberg.
