Today might be the last cool day for a while, with summer-like temperatures arriving later this week.
High temperatures today will be in the mid-70s inland and near 70 along the coast, but those temperatures are expected to rise significantly by Wednesday.
The National Weather Service predicts that high temperatures Wednesday and Thursday inland will be in the 90s, with afternoon high temperatures along the coast to be in the mid-80s.
A heat wave indicates at least three successive days with temperatures of 90 degrees or higher.
The weather service said that Friday may cool off slightly before a cold front moves across the region.
While this year’s winter and early spring were unusually warm, June has so far been relatively cool, especially compared with last year. This June’s average temperature so far has been 66.6 degrees, or 2.4 degrees below normal.
June 2011 marked several heat extremes reported, with the earliest temperature of 100 degrees or higher recorded on June 9 and the hottest June on record.
