Good morning Augusta.

The freeze warning expires today at 10 a.m. – winter will be here shortly folks.

This morning it is clear with a High of 52F. Winds from the West at 5 to 10 mph.

Tonight it will be mostly cloudy in the evening, then overcast with a chance of rain. Low of 37F. Winds less than 5 mph. Chance of rain 50%.

The readings taken from my own weather instrumentation are:

A relative humidity of 67% with a Dew Point of 27.4ºF and a wind chill of 29.3ºF.    

The temperature is 36.7ºF.

Presently we have  West Southwest winds between 5.8 MPH and 9.4 MPH.     

Our Barometric pressure is 30.30/HPA 1026.0 and rising with a weather graphic indicating sun.

The UV rating is 0 out of 16, sunset will be at 5:57 PM with Moon Rise at 4:34 a.m. Eastern Daylight Time, and the moon phase is waning crescent.

For the pilots out there: Raw METAR is –

Visibility is 10.0  miles / 16.1  kilometers with clear conditions and a pretty good ceiling.

We have had no rain over the past 24 hours in this area.

IT is that time of year where it is cold enough to remind you what wind chill really means.

The windchill factor is the temperature that a person feels because of the wind. For example, if a thermometer reads 35 degrees Fahrenheit outside and the wind is blowing at 25 miles per hour (mph), the windchill factor causes it to feel like it is 8 degrees F. In other words, your 98-degree body loses heat as though it is 8 degrees outside.

The windchill factor is the same effect that causes you to blow on hot soup to cool it down. The movement of the air increases the soup's loss of heat by convection, so the soup cools down faster.

For an inanimate object, windchill has an effect if the object is warm. For example, say that you fill two glasses with the same amount of 100-degree water. You put one glass in your refrigerator, which is at 35 degrees, and one outside, where it is 35 degrees and the wind is blowing at 25 mph (so the windchill makes it feel like 8 degrees). The glass outside will get cold quicker than the glass in the refrigerator because of the wind. However, the glass outside will not get colder than 35 degrees -- the air is 35 degrees whether it is moving or not. That is why the thermometer reads 35 degrees even though it feels like 8 degrees.
