Monday will start of the week on a humid and relatively cloudy note for the Commonwealth, with highs in the upper 70s and dew points in the upper 60s. Due to the humidity, there will be scattered storms in the afternoon. Rain out ahead of tropical storm Isaias moves into the eastern half of the state for Monday night and Tuesday morning before the storm itself enters the region late in the day on Tuesday. The center of the storm looks to stay just east of the state, moving from the Delmarva across New Jersey and into southern New England. This will keep the Commonwealth on the western side of the storm so most of the strong wind will stay to the east, though Philadelphia and the eastern fringe of the state will still likely see a few tropical storm force wind gusts. However, the storm will still be a significant rain maker for the eastern part of the state, with several inches of rain possible for the area. This rain brings a risk of flooding in these areas. The central and western parts of the state will receive a little rain from the system too, though the heaviest rain will stay in the east. The storm moves out Tuesday night and a much more comfortable air mass moves in for Wednesday and Thursday. Dew points will fall into the 50s and possibly the upper 40s during the day on Wednesday, with temperature slightly below average. Thursday looks to be almost a repeat of Wednesday though the southeastern part of the state will see a few showers due to a weak low situated to the south of the state. The humidity increases again on Friday, and this will lead to scattered afternoon storms throughout the state. This higher humidity looks to stick around for the weekend and the start to next week and it will be accompanied by increasing temperatures as well.
