Hurricane Erin may bring isolated flash and urban flooding, landslides or mudslides, and possible tropical storm conditions to Puerto Rico and the U.S. Virgin Islands this weekend. Scattered thunderstorms and heavy rainfall may bring areas of flooding this weekend over the Upper Midwest. A tropical disturbance will bring locally heavy rain and mainly urban flash flooding to far southern Texas. Read More >
These graphs show approximately how the previous package of normals (1981-2010, in blue) compares to the current one (1991-2020, in orange). These graphs directly compare the two datasets. To create a truly equal basis for comparison, one would need to recalculate the old normals with the data management and computation strategies that were used for the new normals. However, according to a spokesperson from the National Centers for Environmental Information (NCEI), the results from using the recalculation technique should not vary significantly from the results of a direct comparison. Once NCEI makes those recalculated normals available, a new comparison can be developed. In the meantime, the direct comparison shown in the following graphs should still give a general impression of how the normals changed from the old package to the new.
