Daily, Monthly, Seasonal and Annual Climate Reports

 The Daily Climate Report (CLI) is produced twice a day, at around 4:30 pm and 1:30 am. The 4:30 PM report contains data from 12:00 am EST (1:00 am EDT) to 4:00 PM local time and is referred to as "preliminary" data. The 1:30 am "daily" report contains 24 hours of data starting at 12:00 am EST (1:00 am EDT) the previous day.

 Monthly reports are produced after each month has completed. Seasonal reports cover a three month period: Dec-Feb for Winter, Mar-May for Spring, Jun-Aug for Summer, and Sep-Nov for Fall.
