A tornado warning is in effect for the Williamsport area as a nasty line of storms presses southeastward across Pennsylvania.
It's unclear how strong that line would be if it gets this far, but the masters of mayhem at the Storm Prediction Center in Oklahoma have Philadelphia in the "moderate risk" zone for severe weather.
The watch is in effect for Philadelphia and all the neighboring counties on both sides of the river until 11 p.m.
It appears that any storms in the immediate Philadelphia area would arrive right after the peak commuting periods.
Meanwhile, the steam bath is back. The temperature didn't get quite as high as expected -- it was 93 at 4 in Philly -- but the heat index was at 100.
A reminder: The Philadelphia Corporation for Aging will keep the heatline open until 8 p.m., 215-765-9040.
