Nbc 10 first alert chief meteorologist glenn hurricane schwartz tells us what to expect. I believe this is going to start by the morning rush tomorrow. The leading edge of the clouds has already gotten into philadelphia. That is a sign of things to come. This tremendous area of moisture is headed right in our direction. The clouds, you can see already, increasing across the area. The first alert is for the entire area, for the rain thats going to affect us from Tuesday Morning all the way to wednesday night. Not constantly, but there are going to be two specific bursts of that. Periods of heavy rain, slippery roads, and of course the clogged drains due to the leaves. Normally, an inch or two of rain wouldnt necessarily be as big a deal as it is likely to be in this case, because of those leaves blocking the storm drains, you want to sweep some up tonight and consider those slippery conditions for tomorrow morning. There is no doubt that rain is coming in. It wont come in this evening,
