NOVEMBER 22ND
HISTORIC WEATHER EVENTS

An observer at Boston MA recorded a "great tempest of wind and rain from
the southeast all night, as fierce as a hurricane, and thereupon followed
the highest tide which we have seen since our arrival here". (David Ludlum)
...1957...
Extremely destructive Santa Ana winds blew from Oxnard to San Diego and
inland parts of southern California. The high winds produced a 28,000 acre
brush fire on a 40-mile front west of Crystal Lake. People were ordered off
streets in some areas due to flying debris. (21st-22nd) (The Weather
Channel)
...1991...

the London, KY Corbin Airport in 1991. London measured 2.18 inches of 
rain...while Jackson picked up 2.99 inches of precipitation. Both amounts
