Questions & Answers about Det kommer att regna och blåsa på måndag.
Why do we use kommer att here instead of ska?
We use kommer att for future predictions, especially for things we cannot control like the weather. If you used ska, it would sound like you are personally planning or promising to make it rain!
Do both regna and blåsa connect to kommer att?
Yes. After kommer att, the main verb must be in its infinitive (dictionary) form. Because they are joined by och (and), the kommer att applies to both verbs, so both regna and blåsa stay in the infinitive.
Is blåsa the usual way to say it will be windy?
Exactly! While English often uses an adjective (it will be windy), Swedish commonly uses the verb blåsa (literally "to blow") to describe windy weather.
Why is it på måndag for "on Monday"?
When talking about an upcoming day of the week, Swedish uses the preposition på followed by the singular day. If you wanted to say "on Mondays" as a repeating habit, you would use the plural form på måndagar.
