On January 21, 2005, Oklahomans and North-Texans kept their coats in the closet, as an unseasonably warm airmass allowed afternoon temperatures to climb into the 70s. A 37-year-old record was broken at Oklahoma City, as the temperature soared to 77 degrees, breaking the 1967 record by 6 degrees.

Long period waves from a distant storm produced a wave climate on the beaches of Northern California that had a very strong set behavior, though the overall wave height was well below advisory criteria.
Lightning associated with an early morning thunderstorm hit a home in Ocoee. The lightning strikes started a fire which destroyed the home.
A large swell from the north in combination with strong trade winds produced surf of 8 to 15 feet along the east-facing shores of Kauai, Oahu, Molokai, Maui, and the Big Island. A man drowned in windward Big Island waters in the rough surf on the 22nd.
Very high surf conditions (25-28 feet) developed along the Central Coast. The high surf swept a man off the rocks near Morro Rock.
Warm, moist air moved over an extensive snowpack to cause rapid melting of the snow. The result was dense advection fog which reduced visibility to less than a quarter mile and in many areas near zero.
With high pressure remaining dominant over the area, dense fog formed over much of the San Joaquin Valley north of Kern County during the early morning of January 21 where skies remained mainly clear and winds remained light.
