What happened

The episode as NWS PHI wrote it up.

November 2001 continued the run of unseasonably dry weather. All of Eastern Pennsylvania received less than half of its normal monthly precipitation and was less than one fourth of its normal precipitation totals around Philadelphia. The mounting precipitation deficits prompted Pennsylvania Department of Environmental Protection Secretary David E. Hess on November 6th to issue a drought warning for South Central Pennsylvania (including Chester County) and a drought watch for the rest of Eastern Pennsylvania. The drought warning for Chester County called for a ten to fifteen percent voluntary reduction in water consumption while the drought watch elsewhere called for a voluntary five percent reduction of non-essential water use. On November 8th the Pennsylvania Game Commission banned all open fires in the 1.4 million acres of state game lands due to the very high or extreme risk of fire. There have been about 250 wildfires in the state since July. Monroe County enacted a countywide one month long burning ban on November 18th. The unseasonably dry weather was also leading to increasing well problems. On a county weighted average, November monthly precipitation totals ranged from 0.8 inches in Philadelphia County to 1.9 inches in Monroe County. Normal is around 3.9 inches. At the Philadelphia International Airport, the monthly precipitation total of 0.56 inches was the third driest November on record. November monthly precipitation totals were 1.23 inches at the Reading Regional Airport and 1.10 inches at the Lehigh Valley International Airport.
