I pulled some data from NOAA on high temperature records for October 2007.
# U.S. Monthly Highest Max Temperature Records set in October 2007After downloading all of the details into Excel and using the subtotal and max functions to locate the highest record for any location on any day in October for each state, I compared it to the all-time high temperature records for October for each state [click on image for larger view]:
# NOTE: These records are based on the historical daily observations archived in NCDC's
# Cooperative Summary of the Day data set and preliminary reports from Cooperative
# Observers and First Order National Weather Service stations, and as such are subject to change.
# When the 6-digit COOP ID does not exist for a station the WBAN ID (5 digits) is used.
# All stations displayed have at least 30 years of data with a minimum of 50% completeness.
# Units are °F.
# # Total Number of Records for October 2007 # New: 134 + Tied: 125 = Total: 259
According to NOAA data, there were locations within 26 states that experienced record highs, but when you compare those to the state records for the month of October [1880-2006] you find that zero states had new high temperature records.
This is despite land use changes, including the spread of the urban heat island effect cities, that raise recorded temperatures in many locations.So, when you hear that 259 high temperature records were either set or tied in October... take it with a grain of salt.
Then look at the image above and see when the records were really set...
