Area-averaged Extreme Minimum Temperatures in Maryland:
1 January - 31 December, 2024

This analysis identifies days when daily minimum temperatures are smaller than 32°F, 28°F, and 24°F. If these freezing days occur for two or more consecutive days they define a spell. Summary tables can be seen in the following links for days below 32°F, below 28°F, and below 24°F.

NOTE: The plots are created from preliminary NCEI's nClimDiv-Daily data set, v1.0.0. Data labeled as scaled on January 10, 2025.

The blue line in each panel marks the extreme temperature threshold of 32°F, 28°F & 24°F.
