How do we determine what “normal” weather is? Climatologists use a 30-year average to calculate normal temperature and precipitation for stations around the US. The last averaging period was 1981-2010, which means that we have less than a year to go before the next averaging period begins (1991-2020). How are the normals expected to change when those calculations are complete. It’s still too early to say (we do have almost a year to go) but Becky Bolinger from Colorado has done a quick preliminary look at what we might expect. There are some expected results (Alaska is getting warmer) and some not so expected (November is getting colder in the Southeast). You can read more about it and see all the maps here.
