Foggy Start = Cooler Temps

I woke up this morning and was happy that there was fog since it was in the forecast, but that October sun angle did NOT help burn it off very quickly this morning at all, so thankfully the pheasant opener was at noon!This area of white, on the satellite image, I circled is the fog many in Sioux Falls saw this morning...

The reason we had a cooler day than forecast is because this fog didn't burn up as fast as I expected it to. The reason for that is because the low angle of the sun in October makes it harder for that fog to evaporate. There's also an inversion (kind of like a Tupperware lid that keeps food staying the same) that kept a low cloud deck around the Sioux Empire. So those low clouds kept the sun and warmer temps away.

By the afternoon hours you can see those level clouds disappeared from that same area. More fog is in the forecast for Sunday morning as we will have light winds, clearing skies and some low level moisture. Temperatures will still be in the 60s for Sunday before a cold front passes through mid-day bringing much cooler weather.
