2014 brought the Dallas-Fort Worth its coolest July in seven years according to National Weather Service (NWS) data for DFW International Airport.

A few bullet points for the month:

  • Average high temperature 93.7 degrees, 1.9 degrees below normal
  • Average low temperature 73.9 degrees, 1.2 degrees below normal
  • Average temperature 83.8 degrees, 1.5 degrees below normal

Sadly, precipitation was also below normal. Two flash flood events took place just to the north of Denton during the month, but this rain dodged Tarrant and Dallas Counties. In fact, DFW airport recorded just under an inch of rain at .98”, about half of the normal for the month.

Other Metroplex rain gauges also ran on the dry side. Here are some other July precipitation totals:

  • Arlington…..1.34”
  • Dallas-Love…..1.18”
  • Fort Worth…..0.99”

Locations along the northern tier of Metroplex counties such as Collin and Denton fared better, as they benefitted from the heavy rain events:

  • Denton…..6.24”
  • McKinney…..4.80”

According to the latest Drought Monitor report, the DFW area remains in a severe to extreme drought. Northern Denton and Collin Counties have seen the drought ease after the two recent heavy rain events, but stingy skies have left “Big D” and “Cowtown” with little improvement.

Another telling statistic is area lake levels. Lake Ray Roberts rose more than three feet during the last two weeks of July as it absorbed runoff from the Denton area rainfall, and Lake Lewisville rose more than two feet. However, Lake Lavon in eastern Collin County increased only a few inches and it remains at 50% of normal, some 11 feet below its “full” level.

The outlook into early fall calls for a weak El Nino to develop; this usually provides an active weather pattern with above normal precipitation, so there’s cause for hope that the drought will ease over the next few months.
