Your Sunday looks nice overall with a mostly sunny start to the day, though clouds will increase from north to south in the afternoon ahead of an approaching cold front. Otherwise, expect a pleasant day with high temperatures in the 70s. Heading into Sunday night, a few showers will be possible very late, but will be long gone by Monday morning.
As far as the work week goes, it starts off fantastic with lots of sunshine, and highs staying in the 70s and lows in the 50s. After Tuesday, we see a big warming trend with highs back in the low to mid-80s by the end of the week.
