Precipitation measurement is "inches"
Precipitation "T" = trace, precipitation was observed but not enough to be measured
NORMAL (Norm) refers to the 1981-2010 Standard Normals
DEPARTURE is APRIL 2018 Average measured against 1981-2010 normals, °F.
Max = Observed Maximum and Min = Observed Minimum temperatures in °F.
Mean = Observed Mean Daily temperature in °F.
Dep = Departure from normal ( __ = below normal, + above normal), in °F.
Pcpn = Observed daily precipitation (midnight to midnight, CST) in inches.
Rec Pcpn = Record daily amount of precipitation in inches.
Rec Max = Record maximum temperature in °F.
Rec Min = Record Minimum temperature in °F.
HDD = heating degree day units (base of 65 degrees) in °F.
CDD = cooling degree day units (base of 65 degrees) in °F.
Norm Max = Daily Normal High Temperature (1981-2010 normals) in °F.
Norm Min = Daily Normal Low Temperature (1981-2010 normals) in °F.
Norm Mean = Daily Normal Mean Temperature (1981-2010 normals) in °F.
