First Half of Warm July Review


July 2011 has started out a bit like July 2010 -- not as extreme in the heat department but still pretty darn warm.   Temperatures through yesterday were averaging 3.2 degrees above the old averages, 2.3 degrees above the new averages (average temp of 80.4).   We likely won't approach July 2010's standard of heat (81.7) for the month but we will probably see a top ten warmest July on record once all is said and done locally.   Month-to-date, we've had nine days of 90 or warmer in Philadelphia and we'll likely add another half dozen or more in the month's second half as we enter a heat wave this week.

In terms of rainfall, the city and points north/west are generally drier than average.   Philadelphia has picked up 1.51" of rain this month, almost all of it falling on July 8th (that Friday with the heavy thunderstorms).   The only areas that are above average -- much of it thanks to other thunderstorms that popped that week -- are across the Pinelands in New Jersey.   The rest of us are generally pretty dry or very dry, with rainfall rates running near 50% of normal this month.
