It’s July 4th with 1\/3rd of the summer behind us, and it has not officially hit the century mark at DFW Airport this season. What gives? Well, the average date for the first triple digit reading at DFW Airport is actually only July 1st. There are several other factors that have kept us below the century mark so far.\u00a0 For one, we have seen above normal precipitation to date. This collects in the ground and keeps the grounds from drying out like\u00a0it normally would this time of year. The increased precipitation has also\u00a0kept things greener than normal. The evapotranspiration\u00a0effects (the process by\u00a0which water\u00a0is evaporated back into the atmosphere from the soil and\u00a0plants)\u00a0actually helps to slow the temperature rise while also providing more humidity which makes it feel hotter than it actually is outside. Another reason the temperatures have largely remained below 100\u00b0F is that the typical summertime ridging has largely been centered out to our west across the desert southwest. It has been very\u00a0hot in this region so far this summer. The influences of this ridge has so far been pretty minimal compared to other summers. North Texas has actually been caught between the ridging out west and troughing over the east, and this has provided for more northerly\/northwesterly flow aloft patterns than is typical during summer. This has actually allowed more opportunities for rain as disturbances move into our area around the ridge. So, given that DFW Airport picked up another nearly 2 inches of rainfall overnight, the ridge not fully building in strong keeping heights lower and H85 temps not as warm, and a breezy pattern at the surface keeping the boundary layer well mixed,\u00a0the chances of seeing 100\u00b0F at DFW Airport over the next few days seems pretty unlikely. Highs will continue to top out around 96\u00b0F to 98\u00b0F with heat index values between 103\u00b0F and 105\u00b0F.<\/p>\n","protected":false},"excerpt":{"rendered":"
