Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

The information in the tables below represent the average dates on which the prescribed temperatures occurred - the climatological average first or last frost and freeze dates. Many variables dictate the actual first frost or freeze, including cloud cover, wind speed, soil moisture and location of the temperature sensor. Some temperature reporting sites are located in town while some are more rural. Sites in town tend to experience frosts and freezes a little later in the year, while rural sites tend to see frosts and have freezing temperatures a bit earlier. Based on 1991 - 2020 data.

NOAA's 1991-2020 Climate Normals
NOAA's National Centers for Environmental Information (NCEI, formerly NCDC) released the 1991-2020 Normals on May 4, 2021. Climate Normals are the latest three-decade averages of climatological variables, including temperature and precipitation. This new product replaces the 1991-2020 Normals product. Additional Normals products; such as frost/freeze dates, growing degree days, population-weighting heating and cooling degree days, and climate division and gridded normals; will be provided in a supplemental release at a later date.
