Today (Wednesday): Partly mostly sunny, hot and humid. Afternoon highs should be in the mid to upper 90s with heat index highs of 105 to 110. A difference today is a noticeable wind from the south, increasing to 10 to 20 mph in the afternoon. So it should move the air a bit, although this will only serve to reinforce the moisture from the south. An isolated shower or thunderstorm is possible in the afternoon. Confidence: Medium High
Tonight: A line of showers and storms is seen crossing the region from west to east as a cold front moves in between 6pm and midnight. However, it is uncertain whether it will be a solid line that submerges the entire region or a line broken by rains and storms. A few storms may have damaging winds. The humidity starts to drop a bit with the wind blowing out of the west and lows in the mid to low 70s. Confidence: Medium
