NOTES:

  • Temperatures are degrees F, precipitation is inches of liquid. All normals are based on the period 1971-2000.
  • HDD=Heating degree days, CDD=Cooling degree days
  • Daily normal precipitation values are more appropriate for calculating normals over a period of at least several days, rather than on a strict day-to-day basis.
