High pressure is moving off the coast into the Atlantic Ocean. Southwest wind will help boost our temperatures up a couple degrees as our temperatures climb.
This will get our temperatures back to more seasonable conditions.
The dew points will still remain relatively low for this time of the year in the 50s, so humidity will not be a huge problem.
Clouds will stream in from the west through the Ohio Valley. Sunday night, the southwest will continue and overnight lows will be fairly warm for this time of the year. Dew points will also rise back into the 60s Sunday night.
By Monday, a low pressure moving into Quebec will have a trailing cold front through the Ohio Valley. Showers and thunderstorms will move through the the Ohio Valley into central Pennsylvania.
A few thunderstorms can make it into the Poconos and western parts of the viewing area. The I-95 corridor will remain dry throughout the day, but we could see debris clouds from the thunderstorms that do form to the west.
Monday will be the first real hot day with deep southwest flow causing breezy conditions, and we will see temperatures rise into the lower to middle 90s. Dew points will remain in the 60s, so it will feel more like the upper 90s to near 100.
Tuesday will be the warmest day of the next seven. A secondary cold front will move through the Great Lakes into Canada. This will have a trailing cold front through the Ohio Valley.
The thunderstorms will once again form across central Pennsylvania on Tuesday with most of the activity once again remaining in the mountains and into the Susquehanna Valley and western Maryland.
The I-95 corridor may see something spotty in the evening. Temperatures will be getting into the middle 90s with the humidity feeling close to 100.
