A frontal boundary separating drier, warm conditions to our north, from hot and steamy conditions to our south will be the main driver of our weather over the next week. Most days will be rather unsettled with plenty of humidity the boundary nearby (dew points near 70 at times!).

The boundary will be focused from NW PA to southern New England Sunday, allowing the region to be in the warm sector. It’ll be a nice morning, with increasing clouds as a shortwave rides along the boundary. Showers and storms will impact the region later this afternoon with some heavier rain and wind possible. This will last into the evening tonight, with even a few showers and storms possible all night.

The shortwave will move north of the region tonight and Monday with gusty storms possible in the afternoon. The boundary will be very close by Monday and latest trends in guidance keep our region in the warm sector. With that, highs Monday have gone up to near 90 now with lots of humidity. Things will wind down Monday evening and later in the night actually looks dry as things move east and we lose daytime heating along the boundary. Tuesday we will still be near the boundary with plenty of humidity and a shower or thunderstorm around. The location of the boundary is questionable this day, so stay tuned.

As of now, it looks like we will lose some of the humidity Wednesday (dew points down to 60-65) and will have a dry day. Temperatures will remain warm in the mid 80s. The boundary will be around through the end of the week and we may have to deal with some showers and thunderstorms through the weekend before a cold front sweeps everything
out to our east and south by early next week.
