Random Weather Facts

Dew Point
The dew point is the temperature to which air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. When the dew point temperature falls below freezing it is called the frost point, as the water no longer creates dew but instead creates frost. The dew point is associated with relative humidity. A high relative humidity indicates that the dew point is closer to the current air temperature. If the relative humidity is 100%, the dew point is equal to the current temperature. Given a constant dew point, an increase in temperature will lead to a decrease in relative humidity.

Weather History for March 14
 
1990   A large F5 tornado went through Hesston, KS. It was on the ground for more than two hours and 47 miles and was, at times, three fourths of a mile wide. A personal check flew from Hesston to Blaine, a distance of 115 miles! As the Hesston tornado dissipated, a new F5 touched down alongside it that also grew to 3/4 mile wide along a 22 mile path.
2003   A flight from Hawaii to San Francisco flew into severe turbulence about an hour before landing. Five flight attendants and five passengers suffered cuts and bruises when the Boeing 767 made a sudden drop in altitude. Meteorologists say the plane was likely flying near a storm front that was approaching California.
