From Steve LaNore: Texoma goes from floods to dust

Texoma's tap turned off on August 23, with no rain since that time.

Texoma has seen a drastic change in the weather during the past few weeks, going from flooding and muddy yards to dust.

The tap turned off on August 23, leaving us more than three weeks since our rainfall, and things are starting to dry out.

Lake Texoma is still in pretty good shape in the upper 616’s, but the pattern continues to look very dry as we move into the last half of September. In fact, computer projections show no general rainfall for some time, just a few showers here and there next week that probably won’t amount to much.

A reminder that since we’ve begun to dry out, fire danger has increased and outdoor burning is strongly discouraged as we will be in a windy pattern through the weekend.

The attached graphic takes the average rainfall by month for four Texoma locations: Ada, Ardmore, Paris and Sherman-Denison, thus giving a better picture of the pattern area wide. The Sherman-Denison and Paris areas received some of the most extensive flooding this summer with both locations reporting flash flooding in August.

Other regions of Texoma such as southern Pontotoc County also observed flooding, but the most damaging floods were by far in the Sherman area where more than 20 homes were damaged by high water and numerous water rescues were required on the morning of Aug 13th; in fact an apartment complex was also flooded and Sherman High’s Bearcat Stadium had five feet of water in it at the flood’s peak. Over 10” of rain was recorded near Pecan Grove Park that morning, with most of the city getting at least six inches.

So what caused the pattern shift? It was a combination of Hurricanes Harvey and Irma, as Texoma found itself on the northwestern (dry) side of both systems, plus a couple of unseasonably strong cold fronts reinforcing a stable air mass.

It was a relief to see the floods end; now we’re running on the dry side and it looks like we’ll have to wait a while for the skies to wet the grasses’ whistle.
