High temperatures broke the South Sound record both Sunday and Monday, and the rest of the week is supposed to stay warmer than usual for January.
The 61-degree high recorded at Sea-Tac Airport on Monday broke the 2003 record of 58 for the same date. A 63-degree high Sunday broke the 1986 record, also of 58.
And Saturday reached 58 degrees, tying the 1995 record for that date.
Joint Base Lewis-McChord, for which the National Weather Service has no historical records, had a high of 64 Monday.
Weather Service meteorologists think temperatures for the rest of the week will be in the low 50s, with a chance of rain Tuesday, a mostly cloudy Wednesday, and a partly sunny Thursday. Friday is expected to bring patchy fog.
