High pressure that brought delightful weather on Friday will drift to our east, allowing a return flow of warmer and more humid air to enter our area.
Saturday will be sunny and warm. High 85-86. Dew points will still be in the comfortable range.
On Sunday, a weak upper air trough moves through. Temperatures will increase as will humidity, with dew points moving into the more noticeable 60s. High temperatures near 87-88.
The weak trough may result in some cloudiness in the afternoon Sunday. Some weak vorticity also present. The models are showing light showers far to our west, with nothing moving in to the immediate PHL area. I’ll keep an eye on it.
A stronger front moves through Monday night.
