Depends on if the station data they’re derived from is reliable. Funny you posted this because I was just looking at the NOW data for this area for recent Februaries (doing some winter analoging ;) ).

Weird statistical anomaly..we had our warmest February on record in 2017, just 3 years removed from what might be our coldest February on record in 2014 (IAD..haven’t checked the full record yet so don’t hold me to it yet).

2017..a yuuge +8.6 anomaly.

2014..a whopping -10.6 anomaly. ☃️

Some of those days in February 2017 were warmer than SEA’s average July temperature. :lol:
