Iceland is preparing for a significant drop in temperatures as cold polar air is expected to sweep over the country in the coming days. The Icelandic Meteorological Office forecasts that the thermometers may register as much as 18 degrees Celsius below freezing in some areas on this day. The cold air is being dragged in by high pressure over Greenland and low pressure systems west of Norway, contributing to the chill settling across the nation.

In addition to the low temperatures, weather patterns indicate that there will be increased movement of low-pressure systems around Iceland this week. This could bring precipitation throughout various parts of the country, leading to a pause in the dry spell predominantly affecting the southern regions. Specific forecasts suggest that while eastern areas may experience strong winds on Tuesday, conditions will remain relatively dry across most of the rest of the country, except for some occasional snow showers.

As the week progresses, the weather is set to shift with predictions of heavier snowfalls in southwestern Iceland by the end of Tuesday, likely continuing into Wednesday. Wind speeds are expected to decrease gradually while snowfall will begin to pick up in the northern parts of the country by late afternoon on Tuesday, signaling a change that could affect travel and daily activities as conditions become harsher with winter weather returning.
