Philadelphia Week Weather Outlook - Thurs PM
Deep low pressure near the Great Lakes will attempt to spawn a secondary low this weekend in New England. These double low centers are causing differences in the model predictions for this weekend. The NAM and GFS differ by 12 hours with precipitation. The GFS continues the idea that Saturday will start dry and rain will wait for late in the afternoon or early evening. The NAM (which I've recently decided to try to ignore) has rain starting in the morning on Saturday and continuing through the day. The NAM has much cooler temps on Saturday.
For Sunday, the GFS has the rain starting later (on Saturday) and therefore continuing later on Sunday. Much of Sunday morning will be wet (unless we get into a dry slot). I will go with the GFS this week.
Sat 3/28: Cloudy and mild with rain developing late in the afternoon. High near 58.
Sun 3/29: Cloudy with rain ending during the afternoon. Some sunny breaks possible late in the afternoon. Becoming windy. Mild. High 65.

Our cooler than usual weather continues into spring, as the sunspot minimum continues and solar flux remains at a very low level. Expect the spring to be cooler on average. Check out the solar flux at http://www.swpc.noaa.gov/SolarCycle/index.html
