Anna Dorste German and English Freshman tries to survive Arizona's on coming winds and recent weather changes on campus Wednesday, Oct 28th.

The UA campus got a shock yesterday with a sudden cold spurt that dipped high temperatures to 20 degrees below Tuesday's.


The cold spell came after a month of unusually high temperatures, peaking at a rare 99 degrees on Oct. 17, according to National Weather Service meteorologist Glenn Lader. Today's projected high of 59 degrees will be the lowest for this date since 1960, he said.

""This cold snap will help bring those numbers down a little bit but we'll still probably end (the month's average) a little higher than normal,"" Lader said.


The unusual weather was caused by a high-altitude low-pressure system passing over Tucson, explained atmospheric sciences Emeritus Professor Benjamin Herman.


The system creates a pocket of cold air high in the sky that prevents the sun from effectively warming the ground during the day and traps cold air at night, he said.


The air – desribed by Lader as an ""cold storm"" - originated in the Gulf of Alaska and stayed cold as it travelled to the desert Southwest, he said, adding that temperatures are likely to rise by the weekend as the storm passes over.


This kind of weather is normal for the winter, Herman said, but less so for October.


""These things are quite common later in the year, but not usually this early,"" Herman said.
