Philadelphia storm front: Damaging winds, rain to plow through Wednesday night

PHILADELPHIA - Rounds of rain will be pushed across the Delaware Valley over the next two days by a sweeping cold front that will plummet unseasonably warm temperatures and could help produce a rare wintertime thunderstorm.

A system is moving in from the west and will be followed by a lull, then another shot of scattered rain overnight and early Wednesday morning.

Scattered showers and daytime temperatures in the mid-60s will continue through the first half of Wednesday, before a cold front shoves a large system of rain with strong winds across the Delaware Valley.

Forecasters aren't ruling out the possibility of a rare wintertime rumble of thunder as a cold front will mix with the warmer air. Temperatures are expected to tumble nearly 20 degrees on Thursday, with the forecasted high for the last day of February slated to barely reach the mid-40s.

A Wind Advisory has been issued for the north and west counties outside of Philadelphia for Wednesday night and Thursday morning, as damaging sustained winds should reach into the 20 mph range, and gusts will be higher. 

Temperatures will quickly rebound to seasonable levels on Friday, and continue to recover through the weekend with highs expected to return to the low-60s by Sunday and Monday.
