DAILY DISCUSSION AND CLIMATE SUMMARY
MONDAY, OCTOBER 22, 2007 
ALL TIMES ARE IN EASTERN STANDARD TIME
 
SUNNY AND VERY WARM OCTOBER WEATHER CONTINUES TODAY...
 
Very sunny and warm conditions are occurring today with 
temperatures approaching the 80-degree mark. However, 
today's record of 85 degrees in 1979, will not be reached. 
The double-digit departures of the past five days, 
including today, will push the monthly average temperature
up to 7 degrees warmer than normal.
 
Despite the 0.79 inch of rain late Friday and early last 
Saturday, we still need a lot more rain to bring the month 
up to normal. Presently we're running close to one inch 
drier than normal.
