October 2003 Weather Summary

October 1-5: A low pressure system off of the east coast brought some light precipitation to eastern PA through the 2nd.  After a cold front associated with the low moved across the state, temperatures were chilly, though clear skies remained clear due to a high pressure system over the east. Beginning on the 4^th, a low pressure system brought some rainfall. Skies remained cloudy through the 5^th and temperatures cooled some due to another cold front that passed over the state.

October 6-12: A mostly clear sky due to a high pressure system started off the week. The system stayed in place because of a stationary front that left temperatures unseasonable cool. Temperatures slowly started to rise on the 8^th, and stayed relatively warm until the 11th. On the 12^th the temperatures cooled some due to the influence of a low pressure system off of the east coast. The system brought light precipitation to extreme eastern PA on that day.

October 13-19^th:  Temperatures cooled considerably due to a cold front off of the east coast and a high pressure system moved in from the 13^th to the 14^th. Overnight, a low from the west moved northeastward across the state and brought some moderate precipitation. Skies remained cloudy for the majority of the week. Temperatures dropped on the 15^th due to the passing of the low and winds reached up to about 20 knots. Another cold front passed though the state on the 16^th bringing along much cooler temperatures.

October 20-26^th: A low pressure system and a cold front passing over the state dropped temperatures even further and precipitation fell through the 23^rd. A high pressure system over the area on the 24^th and 25^th cleared out some of the remaining clouds. The warm front that passed over the area on the 26^th created warmer temperatures.

October 27^th-31^st: A slow moving low pressure system produced moderate rain over much of the state. A cold front passed late on the 27^th chilling the air, followed by a high pressure system that created clear skies. Another low pressure system traveled over the state on the 29^th and moderate precipitation fell. The eastern coast of PA had higher precipitation amounts from this system. High pressure over the state on the 30^th cleared the skies, though cool temperatures remained in the area through the end of month due to a cold front passage.
