November 2003 Pennsylvania Weather Summary

Nov 1^st-2^nd

A cold front moved through during the day on the 1^st with light rain.  The front then stalled out across the state bringing more shower activity.  High temperatures were in the 70s on the 1^st as warm air was pumped in from the southwest ahead of the front.  After the front passed, temperatures cooled  to the mid 60s for highs.  Lows were steady in the mid 50s.

Nov 3^rd-9^th

The stationary front moved slightly northward and allowed warm air to surge in from the southwest.  A low pressure system developed along the front in the Midwest and tracked northeastward, putting PA in the warm sector on the 5^th.  Temperatures spiked near 80 in KPIT, while the NE part of the state was slightly cooler.  Precipitation fell near and north of I-80 on the 3^rd followed by a dry day statewide on the 4^th.  Light rain fell on the 5^th followed by more substantial amounts as a cold front finally passed on the 5^th-6^th.  High pressure then built in for the remainder of the week, lowering temps and keeping PA dry.  Temperatures cooled considerably as the week progressed with highs on the 9^th in the 30s and 40s.

Nov 10^th-16^th

High pressure moved eastward as a front pushed toward the region on the 11^th.  Precipitation fell ahead of the system on the 11^th and more rain fell as the front passed on the 12^th.  Temperatures were in the 40s and 50s.  The low, now over southeastern Canada, occluded and moved northeastward.  High pressure began to build in on the 14^th and was over South Carolina on the 15^th.  Easterly flow made for light precipitation on the 16^th.  Temperatures were in the 40s with increasingly colder overnight lows.

Nov 17^th-23^rd

The high pressure system split and continued an easterly flow bringing more clouds and light rain on the 17^th.  The high pressure system retreated northeastward as a low began pushing toward the region on the 18^th.  Another low just east of the trailing cold front tracked through PA on the 19^th-20^th bringing moderate to heavy rainfall to most of the state.  Most locations recorded an inch of precipitation.  A ridge of high pressure moved in on the 21^st and dominated the weather for the remainder of the period.  Temperatures ranged from the low 50s to mid 60s.

Nov 24^th – 30^th

Most of the state saw a cloudy start to the last week in November.  On the 24^th, temperatures were balmy (upper 50s – low 60s) ahead of a cold front approached the region.  This front dropped light to moderate rainfall as it passed.  High pressure then built in on the 25^th, which cleared skies and allowed for a chilly night.  Temperatures warmed from the upper 30s to near 50 on the 27^th, however a low moving off the Eastern Seaboard kept the clouds around.  Temps warmed a bit more on the 28^th as another cold front approached from the west.  The cold front moved through on the 29^th with no precipitation associated with it.  High temperatures were only in the 30s on the 30^th as northwest flow behind the front ushered in some cooler air.
