General conventions: Times are in Local Standard Time (LST) unless otherwise noted. Temperatures are given in whole degrees Fahrenheit. Wind speeds are in miles per hour, with wind direction given using a 360 degree compass indicating the direction from which the wind was blowing with respect to true north (e.g. 360 = winds blowing from true north, 180 = south, etc.). Precipitation amounts are given in inches, usually to the nearest hundredth, unless otherwise noted. Trace amounts of precipitation are indicated with a “T.”
