Unconstrained Principal Components (PC) Analysis ordination of average fire weather and fuel moisture conditions within acceptable fire weather windows from 2005 to 2015 for 20 remote automated weather stations in the Bismarck and Grand Forks fire weather zones that span North Dakota and Minnesota, USA (Fig. 1). Weather and fuel moisture conditions within acceptable daily fire weather windows were averaged across five half-season periods (dates listed in Table 3) in each year for each station (645 data rows total). Lines connect each half-season observation to its respective half-season group centroids. Weather and fuel variables are shown in bold text positioned with respect to their loadings on the first (PC1) and second (PC2) principal component axes
