About the Database
This is a series of ArcGIS maps documenting significant or unusual winter storms affecting Arkansas since written weather history began in the state in 1819. Each map has known accumulations from each winter storm or series of storms mentioned.
How the Database was Compiled
The accumulation maps were compiled using newspaper reports as well as archived cooperative observer and Signal Service/Weather Bureau/National Weather Service data and reports.
How the Database is Divided:
What is Not in the Database
While numerous significant events are documented, not all events are represented.
Some Data Limitations:
-
As of now, the earliest documented storm is from 1843.
-
Data before about 1870 is very sparse, but gets more abundant with the beginning of the Signal Service era (1870), and the beginning of special cotton region stations (early 1880s).
-
Nearly every storm documented is sleet, snow or a combination of both.
-
At this time, there are only a handful of ice storms documented, mainly in the period 2000 to present.
-
Simply put…if it was not reported, it was not included in the maps.
