Philly Weekend Weather Update -Sat AM
A change and some uncertainty in the forecast- a backdoor cold front through NY state is close enough to bring clouds to our area this morning. The NAM MOS has sun breaking out by early afternoon, but cloudiness returns later in the afternoon as the front sags south.
The NAM and GFS differ with the position of the front, with the GFS allowing the front to slip to our south, giving us an easterly flow, while the NAM keeps the front to our north, maintaining a warmer southwesterly flow. I'm not really sure which model is correct here, but I'm leaning towards the NAM based on current satellite imagery.
But what appeared to be a perfect summer weekend now looks a bit more uncertain regarding cloud cover and temperatures.
Sat 6/9: Considerable cloudiness, some sun early afternoon, then cloudy with a slight chance of a shower or thunderstorm late. High 88.
Sun 6/10: Partly sunny, very warm and humid. High 90.
