Isnt science great?! The cool spot at 10pm was Fosston MN at 48F. Why? Because of calm winds and clear skies - thus radiative cooling at the earths surface. If a few clouds come over later this evening then temps should go up a few degrees - the blanket effect. If winds would come up, temps might come up a bit - mixing of cooling air near the surface with warmer air a few hundred or thousand feet up. Else, if the temp at Fosston continues to drop to 45F (the currrent dewpoint) then there might be some dew formation, or if the air is moist enough in a deep enough layer, some fog formation. Lots of possibilities out there tonight...
