An image from the Monthly Weather Review, essentially a recap of the weather in the previous month. While this makes a lot of sense in the pre-internet age, somehow the journal is still published today. From the January edition in 1873:
The monthly rainfall returns for January from the Signal Service stations show that there has been in general a deficiency on the Pacific coas; but east of the Rocky Mountains an excess of rain and snow… The mean temperatures for January, as given by the Signal Service reports, show that over the country east of the Rocky Mountains the weather has been generally coler than usual.
Above from a particularly stormy November, 1950.
