Sept 17, 2011 Noon Update

2:30 PM: The forecast from last night mentioned that due to a high pressure over the region, today would bring mostly sunny skies. The high pressure ended up over northern New England, however, and a developing coastal low pressure near the Carolinas was able to spread its cloud cover into the NYC area and as far north as southern New York, and rain in association with this storm is falling as far north as SE Pennsylvania. This area of light rain is moving NE, towards New York City, but the rain is weakening as it is approaching the area of high pressure.
For the rest of today, mostly cloudy skies will continue through the rest of the day with the risk of an isolated shower south and west of NYC. Due to the increased cloud cover, temperatures will peak in the lower 60s inland, in the lower to mid 60s in the immediate NYC area, and the mid 60s in Long Island and southern Connecticut. Mostly cloudy skies will continue through the overnight hours as the coastal low begins to intensify with the rain south of the area, and as the low pressure moves offshore and the high pressure spreads back into the region, skies will clear on Sunday with warmer temperatures. Partly sunny skies will continue on Monday, and the next risk of rain will be on Tuesday.

The next update will be posted tonight, discussing the outlook for the end of next week and next weekend in more details, as well as a brief outlook for the end of September.
