You can also determine whether the rain today or tomorrow will be persistent or more intermittent. A weather front is likely to bring a band of rain which could give a few hours or more of continuous rain, whereas showers will bring short bursts of rain, with dry spells in between. You can see if the showers are likely to be frequent, with one quickly following another, or more isolated, with just the odd one popping up here and there.
The scale along the bottom of the map shows you how heavy the rain will be; dark blue being the lightest, through green, orange, yellow and pink, with white being the heaviest.
