Weather Update- Sun 1 PM
The models have been over-predicting thunderstorms for our area, although the MOS (Model Output Statistics) haven kept the chances of rain never much higher than 60%.
It's also been tough to nail down the cloud cover each day, with today (Sunday) having more sun than I expected.
That said, both the GFS and NAM cranked out precipitation for this afternoon and this radar is beginning to support this forecast with showers and thunderstorms developing in Berks and Lancaster county and moving east. The early afternoon should see many areas having showers and thunderstorms as predicted.

Philadelphia Weekend Weather Update -Sat AM
The poorly defined weather pattern described yesterday is resulting in a poorly defined forecast. A big change where Sunday is now wetter than previously predicted.
The early morning clouds today should break, but cloudiness returns later in the afternoon. Some showers and thunderstorms possible Sat night and before daybreak on Sunday morning with the first front. Much of Sunday will be cloudy warm and humid with showers, thunderstorms.
Sat 6/12: Cloudy, becoming partly sunny during the morning, but with increasing clouds during the late afternoon. Showers and thunderstorms at night. High 85.

Much of Sunday will be partly cloudy/sunny, hazy warm and humid. A thunderstorm is possible in the late afternoon.
Sat 6/12: Mostly sunny but with increasing clouds during the late afternoon. High 86.
Sun 6/13: Cloudy early. Then a mix of clouds and hazy sunshine, very warm and humid. Chance of a thunderstorm after 5 PM. High near 90.

Much of Sunday will be partly sunny, hazy warm and humid. A thunderstorm is possible in the late afternoon.
Sat 6/12: Party sunny but with increasing clouds during the afternoon. High 85.

Philadelphia Weekend Weather Forecast -Sat AM
The models continue to trend towards a less wet and less cloudy weekend.
The boundary line between warm moist air and cooler air north will be near our region. Showers and thunderstorms have broken out yesterday along this boundary, but these showers haven't been able to make it into Philadelphia. A more distinct boundary (front) moves though Sunday afternoon with showers and thunderstorms more likely.
Sat 6/5: A mix of clouds and sun. Showers possible late afternoon although not everyone will get one. Warm and humid. High 89.
Sun 6/6: Cloudy. Showers and thunderstorms likely during the early and mid afternoon. Some clearing possible late afternoon. High 87.

Philadelphia Weekend Weather Outlook -Wed PM
An interaction between a southwesterly moist flow around a Bermuda high pressure system and a slowly developing upper air trough will result in unsettled weather beginning Thursday. The GFS model shows this interaction results in the development of a low pressure system over us on Sunday. The details are not well-defined, so expect changes in the forecast specifics. Unsettled with an increasing chance of showers appears to be the trend.
Sat 6/5: Mostly cloudy, some sun possible. Showers, especially during the afternoon. Warm and humid. High 86.
Sun 6/6: Cloudy with rain likely. Humid. High 80.
