Red sky in morning over Lake Winnebago

"Red sky in morning, sailor’s warning”

Dawn over the lake

A red sunrise reflects the dust particles of a system that has just passed from the west. This indicates that a storm system may be moving to the east. If the morning sky is a deep fiery red, it means a high water content in the atmosphere. So, rain is on its way.

And indeed rain will arrive tonight according to our local weather forecasters...



On the other hand if we'd seen pink skies at dusk,

“Red sky at night, sailor’s delight." 

When we see a red sky at night, this means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west. Basically good weather will follow.
