A pool of chilly air has been on the move in the west.
The Front Range awoke to morning temps between 40-45 degrees, with Denver at 46 degrees.
It was cooler north of town toward Ft. Collins and Cheyenne.
Some impressive rain totals keep streaming in from the remains of Gustav.
Some storm totals in Louisiana have reached the 10-15 inch range.
Notice the big hole on our map -- Arkansas. They have seen a widespread 3 to 7 inches and it continues to rain.
Hopefully they will be part of our network next year.
All eyes remain on the tropics. Hannah wants to get her act together and become a hurricane once again. Current models take it very near the northeast coast of Florida, turn slightly northeast and then make a landfall near Myrtle Beach, SC.
That is still days away so we will just have to watch it and see what happens.
Currently, the storm is moving north at 2 mph.
Conduction is the transfer of heat from molecule to molecule. An example of this would be to hold one end of a straight pin between your fingers and an open flame and you will soon feel the heat of that flame!
Heat flows from warmer to colder regions.
Some materials, such as the metal pin, are good conductors of heat.
Other materials, such as air, are bad conductors of heat.
Air is such a bad conductor of heat that on a clear, calm day -- heat stored in the ground only warms a shallow layer of air immediately above the ground.
Yet the air can carry energy rapidly from one region to another with no problem. So how if it isn't a good conductor?
The answer is convection.
