Weather Rewind: July 29-August 4th, 2012

Last week's weather in the Delaware Valley was typical summer weather -- warm, at times hot, and rather muggy overall. Temperatures for the week averaged out to just over two degrees above normal for this time of the year, with the "coolest" day on Wednesday due to persistent shower and storm activity around the region.  In the wake of those storms on Wednesday with a disturbance moving through the Northeast, heat returned for the latter three days of the week and as a result our tally for 90 degree days now stands at 33 this year, equal to the total we saw last year altogether.

Rainfall in Philadelphia totaled 0.46" last week -- good, but still below what our typical rainfall is in a week at this time of the year (about one inch).  Some places made up for that though -- rainfall to our north and northeast totaled over an inch in some spots...closer to two in some of the highest locations. Northeast Philadelphia, for instance, picked up over an inch and a half of rain between Wednesday and Saturday. The other big story last week with that many storms contained frequent lightning -- eight people locally were struck by lightning between a group of four in Wildwood and a family of four just north of Wilmington.  While all of them luckily survived, lightning is one of the bigger weather killers out there.

Switching back to precipitation, rainfall amounts over the past month have varied around the region but have been heavier to the north and northeast of Philadelphia...with some spots picking up five or six inches the past three weeks while Philadelphia has picked up less than half that.
