The following are the meteorological seasons:
- Spring — March, April, May
- Summer — June, July, August
- Fall — September, October, November
- Winter — December, January, February
Since the meteorological seasons fall on the same date every year, it is easier to compare seasonal and monthly statistics.
This winter featured 2.6 inches of snow in January (parts of North Texas had up to five inches.) and a record low of 12 degrees in February. We had 30 freezes. March begins warm with a severe weather threat early next week.
