How accurate is weather forecasting for each day in the future?

93 viewsOtherPlanetary Science

I feel like for the last 20 years I’ve felt like tomorrow’s forecast is very accurate, 2 days from now is an educated guess (if it says it’s raining, it’ll rain, but not sure what time of day) and 3+ days is unknown.

What advancements have we made in meteorology and what are the current limitations for weather forecasting?

I’ve definitely seen my phone be very accurate in forecasts for the current day like “in 16 mins, it’ll rain for 22 mins and then stop for an hour”

What the exact accuracy is each day out will heavily dependent on the region and what you mean by “accurate”.  So it’s probably difficult to answer that question.

IIRC after about a week simulations are less accurate than historical averages.  That’s because the air molecules have circulated around the earth like 3 times.
