HOUSTON, Texas  (KIAH) -- Showers and storms are likely today across Southeast Texas as a cold front passes through during the afternoon commute. Temperatures ahead of the front will be in the 70s and 80s, and the air will be muggy. However, quickly after the front passes through, the temperatures will plummet into the 60s and overnight lows will fall into the 50s. A second cold front on Tuesday will cool things off even more for Wednesday.
