Urban heat island

Here is the enhanced infrared image from the GOES satellite this morning. This temperature sensitvie image typically shows the coldest cloud tops. This morning the blue over Minnesota captures the arctic temperatures. Notice the patch of white over the Twin Cities that is somewhat warmer than the surrounding air.

For example Chaska was recording 22 below zero, while the International Airport was measuring 17 below zero at 7am.

Also note how the < -35°F cold air across northern Minnesota is highlighted based on this color scale.

Craig,

This is very interesting to actually see the heat island effect. It doesn't make me feel any warmer though.

BTW, thanks for all you do with JetStreaming. I look forward hearing them each week. I'm admittedly a weather nut. That's what I get for working with Paul Douglas for a few years. Guess it does rub off.

Keep up the good work!

Dave
