With a persistant easterly wind off the ocean, a shield of clouds has kept the Philadelphia Metro cool and grey. That trend will continue into tonight with winds nearly calm and mostly cloudy skies. Lows tonight around the city will stick in the mid-50s with some areas to the south getting down to the upper 50s and we're able to keep the daytime heating close to the ground, thanks to the blanket of clouds. Tomorrow, the clouds will start to erode as winds shift up from the southeast. More sunshine will also mean more warmth as we are forecasted to reach into the 70's again. This may be one of the last times we reach the 70-degree mark before Old Man Winter comes knocking. Temperatures regionally in the upper 60s to lower 70s to the north and west and into the mid-70s to the south and east.
On Saturday, we'll start to watch out for some effects from Sandy. There are still many possibilities, but a hybrid tropical storm/Nor'easter seems like the best description for what might transpire. Remember, both nor'easters and tropical systems are very wide and span hundreds of miles, so even if we don't get a direct impact, we can still feel some effects from it. We'll be posting more Sandy-specific posts in the upcoming days and will be tracking for you. I'll be posing more from my conversation with the NWS tomorrow in a special post.
Saturday will start out nice, with partly cloudy skies and turning more cloudy by the end of the day. Temperatures will be flirting with the 70-degree mark again making Saturday the perfect day to be preparing for the storm. Starting on Sunday, we'll see some banding in the clouds, a sign the outskirts of the storm are in the region. Skies will be mostly cloudy and we could see some outer rain bands pass through as well. Sunday evening will also start to get breezy. Obviously, depending on the track and whatnot will depend on the severity of the weather, but the general timeframe shows Monday and Tuesday to be the most likely worst days. Strong gusty winds and heavy flooding rains are possible. Power outages and flooded roadways are also a possibility, however it is all dependent on the track.. Monday starts our temperatures becoming cooler as the trough in the jet stream, the second player to this big forecast, brings down cooler air. Wednesday and Thursday, we start to clear out and dry out. Skies turn partly sunny to partly cloudy with a chance of lingering showers.
