Discussion

Temperatures yesterday did indeed reach 90 degrees for the first time this year in Philly (high of 93 at PHL) and they'll make a run at the middle 90's today which would be the highest levels since last July. Relief is definitely in sight; however, for Friday, Saturday and Sunday in terms of temperatures as high pressure builds in across southeastern Canada sending a back door cold front through New England and into the Mid-Atlantic region. This cold front will approach the region later tonight and will help to generate some shower and thunderstorm activity in the Mid-Atlantic region after a mainly sunny and hot day. Some of the storms that form late today and tonight can be on the strong-to-severe side in parts of the area. This cold frontal system will stall to our south and then lift northward this weekend causing the likelihood for some shower and thunderstorm activity in the Mid-Atlantic region; especially, from southern PA southward to the DC metro region.
