Squall Line Possible This Evening


Hi everyone. This is a specialĀ alertĀ post, as we have a threat for a damaging squall line to form. A warm front will pass through the area this morning and combine with a southerly flow, creating instability in the atmosphere this afternoon. Storms should form in northern PA by mid afternoon and start moving southeast. I do expect a severe thunderstorm watch to be issued by this afternoon, as the squall line gets its act together. The storms will mainly have very damaging winds and dangerous cloud to ground lightning. Skies should start to clear after 9 PM tonight, after the line moves through.

High res model 6 PM
High res model at 7 PM today

The Phillies are also playing tonight, and the game will likely be affected by these storms. We have another chance of t-storms tomorrow, as a cold front will move through the region.
