MONTHLY SUMMARY	

For the 4th consecutive July, temperatures were above normal. It was quite hot and humid, with consistently
above normal minimum temperatures, averaging in the upper 60s, until the final week when cooler and notably
less humid air finally moved into the region. There was a lack of extremes in either direction, and we did
not experience the intensity of the July heat waves of the previous three years. The most pronounced heat
episode was during the middle of the month, with 6 of the 7 90+ degree readings occurring consecutively from
the 14th-19th. Lows were in the upper 60s to low 70s, though only one of these mild lows set a record. 6 of
the last 8 days had highs in the 70s, with 5 lows in the 50s, a pleasant change from the heat and humidity
the balance of the month.

Despite the lack of any heavy precipitation events (though a modest rainfall record was set on the 7th), the
stormy pattern of the first 12 days, 9 of which saw measurable rainfall, brought over 2 inches of total rain.
Had this pattern continued at a similar pace, we would have had about 4.5 inches of rainfall, above average
for the second consecutive month. Instead, the weather pattern turned bone dry, with a mere .49" falling
after the 12th. Large storms repeatedly evaporated as they approached and on several occasions dumped large
amounts of rain within 10 miles of this location. The most puzzling aspect of this dry pattern was the flow
of storms frequently from the south or southwest, which often favors heavy rainfall on the lee side of the
Allegheny Front. Instead, the LaVale area appeared to be in the rain-shadow of the mountains once again.
