Heavy rainfall, not the norm for mid-summer, graced Texoma soils and lakes on Thursday, July 17 (see map below). The rain was mostly a good thing with the exception of an extreme pocket of 7 to 11 inches of precipitation falling over southern Cooke and northern Denton Counties, between Gainesville and Denton. The torrential downpour centered on the Valley View-Sanger area where it rained at a rate of three inches per hour for more than three hours.
There were about 30 high-water rescues from motorists stranded on I-35 during the morning hours; luckily no one was reported hurt.
Elsewhere, rainfall ranged one to two inches from Ardmore to Gainesville to as much as five inches in Paris. Flash flooding upstream from us in southwestern Oklahoma will run down the Red into Lake Texoma and should boost the level a couple of feet by the middle of next week.
The July downpours were caused by a well-defined mid-level low moving southeastward in a northwesterly flow pattern and interacting with very moist air.
The outlook through the end of the month shows a much drier pattern evolving with upper level high pressure building in.
