The Smoke Boundary Over Kansas

Smoke boundary over north Wichita.

We've had milky skies over Wichita for much of the last 45 days due to the wildfires to our west. It is unusual that we have the boundary over the city.

The 3pm satellite image shows the sharp boundary over the north part of our city (below).
