Forecast Discussion: Very warm and humid conditions continue across the region this Wednesday afternoon. High temperatures will get up close to 90 degrees with low moderate levels of ozone. Ozone will be improving to the good range Thursday into Friday as a cold front passes through with showers and a thunderstorm Thursday and a drier, cleaner air mass moves in behind this front for the day Friday. A weak front may spawn a shower or thunderstorm across parts of the area late in the day Saturday. Ozone should remain in the upper good range. A nea area of high pressure provides dry weather with near seasonable temperatures Sunday into Monday. A stronger cold front coming through Monday night will bring cooler and drier air back into the picture for the middle of next week.---McAuliffe
