It was a sunshine to clouds day with highs in the middle 40s(44 at Philly International). The clouds moved in due to a warm front pushing northward and with a southerly wind we'll a) be in the 60s for Friday and b) allow moisture-rich rain from the Gulf of Mexico to infiltrate the region for the weekend.
Lows overnight will be in the upper 30s with a mostly cloudy sky; this will lead to an overcast Friday with rain by the evening commute with highs in the lower 60s thanks to a southerly wind. Overnight Friday into Saturday rain will continue with lows in the lower 50s while Saturday itself will be around 60 despite steady rain.
As the cold front pushes through an area of low pressure will ride along the front; this will make Sunday a complete washout with heavy soaking rains as highs will be in the middle 50s. We may seen 2-3" of rain when this is all said and done Sunday evening, but we'll be rewarded for the start of the new work week; how about highs averaging in the middle 60s with a mostly sunny sky?
I don't know about you, but I'd be calling out of work Monday and Tuesday! You can check out the rest of the 7-day forecast(any time) at www.scottderekwx.com/forecast.html .
