Here is a look at high temperatures for Saturday. First graphic is showing only the fire weather stations. These are mostly in Minnesota and located in forested areas. Second are highs at automated sensors at area airports. You will note the very large differences between the Bemidji, Lake Itasca and surrounding areas to that in the Red River valley.

Why is that? Pine trees absorb the sun’s warmth and heats up the surrounding airmass. White snow covered fields without any greenery doesnt absorb much of the sun’s heat and reflects it back to the atmosphere. This will change over time as the snow melts and the black dirt appears, as the black dirt will absorb the sun’s heat. But until then, this time of year will often see in sunny conditions quite large differences between the prairie and pines.
