The weekend ends with a very humid air mass over the Delaware Valley. Dew points reached the 70s on Sunday which is very high. Dew points are another way to measure the humidity.

Once they get above 65 degrees, it feels very uncomfortable outside. Now, changes are on the way as a cold front slides through the Delaware Valley Sunday night.

Ahead of the front, strong to severe thunderstorms broke out again and even a few tornado warnings were hoisted. Once the front moves through, skies will continue to clear and humidity levels will drop overnight as refreshing northerly winds take over. It will be a pleasant start to the work week with sunshine and some clouds for Monday.

Highs will be near 80 with very low humidity. Tuesday starts off with some sunshine but an upper-level low over New England may trigger off a spotty shower during the afternoon. Highs will be even cooler on Tuesday in the mid 70s with more cloud cover.

The below average highs will continue on Wednesday as the upper-level low slowly moves out. Expect some more sunshine on Wednesday with highs back into the upper 70s. The comfortable conditions will continue on Thursday under partly sunny skies ahead of the next approaching storm system. There will be a chance of a shower or storm late in the day at night.

The better chance for showers and storms this week will arrive on Friday as a weak area of low pressure tracks across the mid-Atlantic. Highs on Thursday and Friday will be near 80 degrees. Dry and comfortable conditions will continue for the weekend with sunshine and clouds and warmer highs in the low to mid 80s. There are some hints of another big ridge of high pressure to develop over the mid-Atlantic sometime during the middle of next week, which could mean a return to some heat.
