Cool, wet and Salt/Fresh water freezing temp variations
This morning it is overcast with a chance of rain, then partly cloudy with a chance of rain. High of 63F. Winds from the SW at 5 to 10 mph. Chance of rain
50%.
Tonight it will be partly cloudy in the evening, then clear. Low of 46F. Winds less than 5 mph.
The readings from my own weather instruments are:
The humidity is 88% with a Dew Point of 53ºF, Temp is 52.9ºF and the wind chill is 52ºF.
Our wind direction is Southeast between 0.2 MPH and 1.0 MPH.
Our Barometric pressure is 30.09 HPA 1018 and falling with a weather graphic indicating rain.
The UV rating is 0 out of 16, Sunrise is at 6:19 a.m. sunset is 6:47 PM and Moon Rise is at p.m. EDT and the moon phase is in its last quarter.
For the pilots out there raw metar is:
METAR KAUG 161153Z AUTO 17003KT 10SM BKN075 OVC090 11/10 A3004 RMK AO2 RAE50 SLP175 P0000 60000 T01060100 10111 20100 50003
Visibility is 10.0 miles/16.1 Kilometers with mostly cloudy conditions down to 7500 ft / 2286 m and overcast to 9000 ft / 2743 m.
We received rain of 0.02 inches so far here over the past 24 hours.
Is there a diference between Salt water and fresh water freezing temps?
Below is an article copied from the Farmer's Almanac in 2009.
Facts about freezing temps for fresh and salt water
Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 0 degrees Celsius (32 degrees Fahrenheit), but seawater freezes at about -1.9 degrees Celsius (28.4 degrees Fahrenheit) because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.
At least 15 percent of the ocean is covered by sea ice some part of the year. On average, sea ice covers almost about 25 million square kilometers (10 million square miles) of the Earth.
Sea water becomes more and more dense as it becomes colder, right down to its freezing point. Fresh water, on the other hand, is most dense while still at 4 degrees Celsius (39.2 degrees Fahrenheit), well above the freezing point. The average temperature of all ocean water is about 3.5 degrees Celsius (38.3 degrees Fahrenheit).
